Accounts of natural law moral philosophy and theology sought principles and precepts for morality, law, and other forms of social authority, whose prescriptive force was not dependent for validity on human decision, social influence, past tradition, or cultural convention, but through natural reason itself. This volume critically explores and assesses our contemporary culture wars in terms of: the possibility of natural law moral philosophy and theology to provide a unique, content-full, canonical morality; the character and nature (...) of moral pluralism; the limits of justifiable national and international policy seeking to produce and preserve human happiness, social justice, and the common good; the ways in which morality, moral epistemology, and social political reform must be set within the broader context of an appropriately philosophically and theologically anchored anthropology. This work will be of interest to philosophers, theologians, bioethicists, ethicists and political scientists. (shrink)

It is often supposed that in order to refute the view that laws of nature are necessary truths it is sufficient to appeal to Hume's argument from the conceivability of to the possibility of their being false. But while Hume's argument does present the necessitarian with insuperable difficulties it needs to be made clear just what these are. The mere appeal to Hume is quite insufficient for what he says can be interpreted in more than one way. And if (...) it constitutes an argument rather than a mere assertion Kneale has given reason to suppose that it is at least not obviously valid. The upshot of this article is that Hume's argument may be seen as a direct challenge to the notion that there could be propositions whose modal value is necessarily "opaque to the human intellect".

Jeremy Bentham's powerful metaphor of Injustice, and her handmaid Falsehood reminds us, if we need reminding, that justice requires not only just laws, and just administration of those laws, but also factual truth - objective factual truth; and that in consequence the very possibility of a just legal system requires that there be objective indications of truth, i.e., objective standards of better or worse evidence... My plan [in this Olin Lecture in Jurisprudence, presented at Notre Dame law School, in (...) October 2004] is to sketch some epistemological themes of mine, and explore their bearing on two familiar, radical epistemological criticisms of our legal system: (i) that an adversarial system is an epistemologically poor way of determining the truth; and (ii) that exclusionary rules of evidence are epistemologically undesirable. Neither criticism, I shall argue, is decisive; both, however, throw harsh light on disturbing aspects of the way our adversarial system actually functions. (shrink)

Which mathematical structures are possible, that is, instantiated by the concrete inhabitants of some possible world? Are there worlds with four-dimensional space? With infinite-dimensional space? Whence comes our knowledge of the possibility of structures? In this paper, I develop and defend a principle of plenitude according to which any mathematically natural generalization of possible structure is itself possible. I motivate the principle pragmatically by way of the role that logical possibility plays in our inquiry into the world.

The ethics of Wolfhart Pannenberg has a nomological dimension at its center. Based on the history of the natural law tradition, Pannenberg maintains the possibility of the natural law theory on the following five grounds. -/- The theological ground is his understanding of the Decalogue, the Sermon on the Mount, and the Pauline interpretation of the law. For its historical ground, Pannenberg articulates the natural law theories of Patristic theology and the theologies of Troeltsch and Brunner. (...) The ontological ground is the order of the world, which God established in the process of history. The anthropological ground is the mutuality of human society. The latter two dimensions are related to the epistemological ground, which is based on the hermeneutics of universal history. -/- Pannenberg attempts to combine the law, the gospel, and love in relation to the Kingdom of God. Thus, Pannenberg’s Kingdom ethics is nomological as well as eschatological. (shrink)

One of the more interesting topics debated by Leibniz and Locke and one that has received comparatively little critical commentary is the nature of essences and the classification of the natural world.1 This topic, moreover, is of tremendous importance, occupying a position at the intersection of the metaphysics of individual beings, modality, epistemology, and philosophy of language. And, while it goes back to Plato, who wondered if we could cut nature at its joints, as Nicholas Jolley has pointed out, (...) the debate between Leibniz and Locke has very clear similarities to the topic that has dominated the philosophy of language from the 1970s on: namely, the challenge mounted by Kripke, Kaplan, Putnam, and others against Russellian and Fregean descriptivist accounts of meaning. Yet, this topic is also, as Jolley writes, one of the “most elusive” in the debate between Leibniz and Locke.2 The purpose of this paper is to examine in detail Leibniz’s critique of Locke’s distinction between real and nominal essences. In doing so, I <span class='Hi'>hope</span> to show certain virtues in Leibniz’s account of metaphysics and philosophy of language that usually escape notice. While I wish to provide a general account of Leibniz’s disagreement with Locke, I also plan to focus on the nature of species and natural kinds. In my opinion, those who have treated this topic have not paid sufficient attention to Leibniz’s claims that “Essence is fundamentally nothing but the possibility of the thing under consideration” (A VI, vi, 293) and “essences are everlasting because they only concern..

In 'Quiddistic Knowledge' (Schaffer [2005]), Jonathan Schaffer argued influentially against the view that the laws of nature are metaphysically necessary. In this reply I aim to show how a coherent and well-motivated form of necessitarianism can withstand his critique. Modal necessitarianism -- the view that the actual laws are the laws of all possible worlds -- can do justice to some intuitive motivations for necessitarianism, and it has the resources to respond to all of Schaffer's objections. It also has certain (...) advantages over contingentism in the domain of modal epistemology. I conclude that necessitarianism about laws remains a live option. (shrink)

In his Essay concerning Human Understanding, John Locke explicitly refers to Newton’s Philosophiae naturalis principia mathematica in laudatory but restrained terms: “Mr. Newton, in his never enough to be admired Book, has demonstrated several Propositions, which are so many new Truths, before unknown to the World, and are farther Advances in Mathematical Knowledge” (Essay, 4.7.3). The mathematica of the Principia are thus acknowledged. But what of philosophia naturalis? Locke maintains that natural philosophy, conceived as natural science (as opposed (...) to natural history), would give us demonstrations of the necessary connection between the (ultimately, simple) ideas constitutive of our complex ideas of various natural kinds of substances (e.g., gold). Indeed Locke goes so far as to suggest that a completely adequate natural science would also realize (perhaps, per impossibile) the goal of transforming the corpuscularian hypothesis into knowledge by demonstrating the necessary connection between the ‘microstructure’ (primary qualities of insensible corpuscles) of a particular natural kind of substance (e.g., gold) and the ideas of secondary qualities constitutive of the complex idea of that kind of substance. Locke’s conclusion concerning the possibility of the development of a natural science thus conceived is pessimistic: In vain therefore shall we endeavor to discover by our Ideas, (the only true way of certain and universal knowledge,) what other Ideas are to be found constantly joined with that of our complex Idea of any Substance: since we neither know the real Constitution of the minute Parts, on which their Qualities do depend; not, did we know them could we discover any necessary connexion between them, and any of their Secondary Qualities: which is necessary to be done, before we can certainly know their necessary co-existence (Essay, 4.3.14). It is understandable that, with such a conception of the science of nature, Locke found little of it in Newton’s Principia. In this paper, I further explore what might, perhaps with some hyperbole, be termed Locke’s ‘disappointment’ with the Prinicipia as a contribution to natural science. In particular, I argue that Locke’s adherence to the idealist epistemology of the Way of Ideas entails that mathematics cannot lend its certainty as a scientia to natural philosophy. Consequently, he finds more mathematics than natural philosophy in the Principia. (shrink)

Broadly speaking, a naturalistic approach to epistemology seeks to explain human knowledge – and justification in particular – as a phenomenon in the natural world, in keeping with the tenets of naturalism. Naturalism is typically defined, in part, by a commitment to scientific method as the only legitimate means of attaining knowledge of the natural world. Naturalism is often thought to entail empiricism by virtue of this methodological commitment. However, scientific methods themselves may incorporate a priori elements, so (...) empiricism does not follow from the methodological commitments of naturalism alone. And given a suitably-naturalistic conception of the a priori, a priori forms of justification may be compatible with naturalism generally. -/- A priori justification is, in principle, compatible with naturalism – and hence naturalistic epistemologies – if the a priori is understood in a way that is free of some of the inessential properties that have been associated with the concept. I argue that some of the more prominent strategies for accommodating normative notions within a naturalistic framework allow for the possibility of a priori justification. These include reliabilism, instrumental rationality, and (partial) nonfactualism about justification. A priori justification thus need not be seen as standing in opposition to all naturalistic epistemologies. It is only with nonnormative naturalistic epistemologies that a priori justification per se is incompatible, and this only because the notion of justification itself has no role to play within a nonnormative approach to epistemology.

I discuss the attitude of Jewish law sources from the 2nd–:5th centuries to the imprecision of measurement. I review a problem that the Talmud refers to, somewhat obscurely, as impossible reduction. This problem arises when a legal rule specifies an object by referring to a maximized (or minimized) measurement function, e.g., when a rule applies to the largest part of a divided whole, or to the first incidence that occurs, etc. A problem that is often mentioned is whether there might (...) be hypothetical situations involving more than one maximal (or minimal) value of the relevant measurement and, given such situations, what is the pertinent legal rule. Presumption of simultaneous occurrences or equally measured values are also a source of embarrassment to modern legal systems, in situations exemplified in the paper, where law determines a preference based on measured values. I contend that the Talmudic sources discussing the problem of impossible reduction were guided by primitive insights compatible with fuzzy logic presentation of the inevitable <span class='Hi'>uncertainty</span> involved in measurement. I maintain that fuzzy models of data are compatible with a positivistic epistemology, which refuses to assume any precision in the extra-conscious world that may not be captured by observation and measurement. I therefore propose this view as the preferred interpretation of the Talmudic notion of impossible reduction. Attributing a fuzzy world view to the Talmudic authorities is meant not only to increase our understanding of the Talmud but, in so doing, also to demonstrate that fuzzy notions are entrenched in our practical reasoning. If Talmudic sages did indeed conceive the results of measurements in terms of fuzzy numbers, then equality between the results of measurements had to be more complicated than crisp equations. The problem of impossible reduction could lie in fuzzy sets with an empty core or whose membership functions were only partly congruent. Reduction is impossible may thus be reconstructed as there is no core to the intersection of two measures. I describe Dirichlet maps for fuzzy measurements of distance as a rough partition of the universe, where for any region A there may be a non-empty set of - _A (upper approximation minus lower approximation), where the problem of impossible reduction applies. This model may easily be combined with probabilistic extention. The possibility of adopting practical decision standards based on -cuts (and therefore applying interval analysis to fuzzy equations) is discussed in this context. I propose to characterize the <span class='Hi'>uncertainty</span> that was presumably capped by the old sages as U-<span class='Hi'>uncertainty</span>, defined, for a non-empty fuzzy set A on the set of real numbers, whose -cuts are intervals of real numbers, as U(A) = 1/h(A) 0 h(A) log [1+(A)]d, where h(A) is the largest membership value obtained by any element of A and (A) is the measure of the -cut of A defined by the Lebesge integral of its characteristic function.

This essay is dominated by three themes that recur contrapuntally in Heisenberg’s writings: observation, description , and ontology —prompted always by a concern about the role played by the subjective inquirer in scientific meaning-making, and by the ontology of scientific claims. Among the related themes are; the tension between paradigmatic concerns with structure and philosophical concerns with reality, the possibility of scientific revolutions, such as relativity and quantum mechanics, that can overthrow the classical traditions of natural science and (...) the inadequacy of a psychophysical parallelism for an epistemology of reason . The influence of Husserl and Heidegger is in his neokantian concern about the role of subjectivity. Heisenberg was a long-time friend of Heidegger and familiar with Heidegger’s hermeneutical phenomenology and its critique of Greek philosophy; he also contributed an essay to a Festschrift in Heidegger’s honor in 1959.

The subjectivism of the Austrian school of economics is a special case of Dewey's transactional philosophy, also known as pragmatism or pragmatic epistemology. The Austrian economists Carl Friedrich Menger (1840-1921) and Ludwig von Mises (1881-1973) adopted an Aristotelian deductive approach to economic issues such as social behavior and exchange. Like Menger and Mises, Friedrich A. Hayek (1899-1992) viewed scientific knowledge, even in the social sciences, as asserting and aiming for objective certainty. Hayek was particularly critical of attempts to apply the (...) empiricism of the natural sciences in the social sciences. Though Hayek was not a positivist in the sense ascribed to Milton Friedman (1912-), because he accepted the possibility of final, objective certainty, Hayek's view of scientific knowledge was closer to that of the logical positivists of the Vienna circle than to Dewey's pragmatism. Mises' a priorism, asserting and aiming for apodictic certainty, represented a more extreme form of objectivism even than Hayek's. Mises was similar in this regard to non-Austrian axiomatists such as Gerard Debreau (1921-2005), though he joined Hayek in eschewing mathematical formalism. In Dewey's contrasting view, the scientist commends new, alternative ways of knowing to the scientific community, offering more profound insight or more efficacious practical applications. Alternative ways of knowing which do not offer practical or intellectual benefits are to be rejected. Both the radical subjectivism of the Austrian school and Dewey's transactional strategy justify rejection of the mirage of social justice. Dewey's knowledge as ways of knowing suggests a broader and more fundamental critique of the socialist position in the calculation debate. The arguments presented by the Austrian school can be reformulated in terms of Dewey's pragmatic philosophy. (shrink)

Philosophy in the period immediately after Aristotle is sometimes thought to be marked by the decline of natural philosophy and philosophical disinterest in contemporary achievements in the sciences. But in one area at least, the early third century B.C.E. was a time of productive interaction between such disparate fields as epistemology, physics and geometry. Debates between the sceptics and the dogmatic philosophical schools focus on epistemological problems about the possibility of self-evident appearances, but there is evidence from Euclid's (...) day of a quite different response. The sceptical challenge provoked the development of theories explaining error formation, showing how illusions can be studied systematically and are subject to prediction. Such theories do not legitimate claims about the nature of the underlying entities perceived, but provide justification for forming expectations about future perceptions. While it overtly focuses on purely geometrical considerations, the Euclidean model of optics nonetheless provides support for certain views about the nature of vision and the physics of light. Moreover, by offering a model in which the image received is not thought to be a perspicuous mirroring of the object seen, Euclid may have helped promote a view of perception as something reconstructed from information received, not as a mere form transferred into the eye. The ancient sceptic may indeed have fulfilled his promise to promote inquiry by focusing attention on problems that escape the attention of a hasty theorist. (shrink)

Following on the arguments adumbrated in his previous works, Piotr Hoffman here argues that the notion of and concern with violence are not limited to political philosophy but in fact form the essential component of philosophy in general. The acute awareness of the ever-present possibility of violence, Hoffman claims, filters into and informs ontology and epistemology in ways that require careful analysis. In his previous book, Doubt, Time, Violence , Hoffman explored the theme of violence in relation to Descartes' (...) problematic of doubt and Heidegger's work on temporality. The pivotal notion deriving from that investigation is the notion of the other as the ultimate limit of one's powers. In effect, Hoffman argues, our practical mastery of the natural environment still leaves intact the limitation of human agents by each other. In a violent environment, the other emerges as an insurmountable obstacle to one's aims and purposes or as an inescapable danger which one is powerless to hold at bay. The other is thus the focus of an ultimate resistance to one's powers. The special status of the other, as Hoffman articulates it, is at the root of several key notions around which modern philosophy has built its problematic. Arguing here that when the theme of violence is taken into account many conceptual tensions and puzzles receive satisfying solutions, Hoffman traces the theme through the issue of things versus properties; through Kant's treatment of causality, necessity, and freedom in the Critique of Pure Reason; and through the early parts of Hegel's Logic. The result is a complete reorientation and reinterpretation of these important texts. Violence in Modern Philosophy offers patient and careful textual clarification in light of Hoffman's central thesis regarding the other as ultimate limit. With a high level of originality, he shows that the theme of violence is the hidden impulse behind much of modern philosophy. Hoffman's unique stress on the constitutive importance of violence also offers a challenge to the dominant "compatibilist" tradition in moral and political theory. Of great interest to all philosophers, this work will also provide fresh insights to anthropologists and all those in the social sciences and humanities who occupy themselves with the general theory of culture.

According to the theory of meaning as justification, semantics is closely entangled with epistemology: knowing the meaning of an utterance amounts to knowing the justification one may offer for it. In this perspective, the theory of meaning is connected with the epistemic theory of justification, namely the theory that undergoes the more explicit attempts of naturalization. Is it possible to extend those attempts to the notion of meaning? There are many ways of naturalizing the notion of meaning, independently of its (...) links with the notion of justification. Our goal in this paper is to explore the possibility of naturalizing meaning using those very links. To this aim, we will evaluate in brief three main directions: a) the interaction between justification and discovery; b) Quine's naturalized epistemology; c) the naturalization of logic. (shrink)

Kant’s claims about supersensible objects, and his account of the epistemic status of such claims, remain poorly understood, to the detriment of our understanding of Kant’s metaphysical and epistemological system. In the Critique of Practical Reason, and again in the Critique of Judgment, Kant claims that we have practical cognition (Erkenntnis) and knowledge (Wissen) of the moral law and of our supersensible freedom; that this cognition and knowledge cohere with, yet go beyond the limits of, our theoretical cognition; and that (...) this knowledge grounds rational belief (Vernunftglaube) in the existence of God, the immortality of our soul, and the real possibility of the “highest good.” This essay untangles some of these claims about practical cognition, practical knowledge, and practical belief and their relation to Kant’s account of theoretical cognition and theoretical knowledge. There is a core conception of cognition and knowledge underlying the accounts of theoretical cognition and practical cognition, which allows for a principled distinction between cases of practical knowledge and practical belief. Kant’s doctrine of the “fact of reason” turns out to be crucial to his claims about legitimacy of and distinction between the two forms of practical cognition, one which constitutes knowledge and another which cannot.

This paper deals with two opposite metaphilosophical doctrines concerning the nature of philosophy. More specifically, it is a study of the naturalistic view that philosophical, hence also epistemological, knowledge cannot be distinguished from empirical knowledge, and of the antinaturalistic view that philosophical, hence also epistemological, knowledge, is pure, that is, independent of empirical knowledge and particularly of the special sciences. The conditions of the possibility of naturalistic and of pure epistemology are studied in terms of phenomenological philosophy. It is (...) concluded that pure epistemology is possible under relatively strong conditions but that the version of naturalistic epistemology which denies the pure basis leads to contradiction. That, however, does not shake the possibility of cognitive science. Following Husserl, we may argue that studies of human cognition are possible on the condition that a first basis is assumed which is not naturalized. (shrink)

Quine's (1969) proposal that the foundationalist programs in epistemology should be abandoned in favor of a scientific study of how we come to hold our theories about the world is still widely misunderstood. It does not eliminate the possibility of rational adjudication of scientific dispute, nor is it essentially tied to behaviorist approaches in psychology. On the contrary, recent work in psychology and philosophy of science can very naturally be seen as embodying the sort of program envisioned by Quine; (...) now freed of behaviorist strictures, it clearly addresses issues that have been of interest in traditional epistemology. This view is defended with particular attention to Quine's concerns with translation and the related concerns with belief individuation which have inspired critics of recent cognitive psychology.

Several philosophers have questioned the possibility of a genetic epistemology, an epistemology concerned with the developmental transitions between successive states of knowledge in the individual person. Since most arguments against the possibility of a genetic epistemology crucially depend upon a sharp distinction between the genesis of an idea and its justification, I argue that current philosophy of science raises serious questions about the universal validity of this distinction. Then I discuss several senses of the genetic fallacy, indicating which (...) sense of ‘genesis’ is relevant to epistemology. Next I consider the objection that psychology is irrelevant to epistemology, and that since "genetic epistemology" is really psychology, "genetic epistemology" is irrelevant to a real epistemology. Finally, I take up the objection that nothing discovered in genetic psychology could be relevant to a genetic epistemology. These last two arguments are based upon what I claim to be a mistaken notion of the nature of psychology. Suitably interpreted, psychology can assist genetic epistemology precisely in the way that the history of science assists current philosonhv of science. *I owe considerable thanks to Jann Benson, Ken Freeman, Bernie Rollin and Ron Williams for their helpful discussions concerning many of the issues discussed in this paper. I also wish to thank David Hamlyn, John Heil, William Lycan, Harvey Siegel and an anonymous reviewer for their comments and suggestions. It goes without saying that none of these individuals (especially Hamlyn and Siegel) necessarily agree with me. An earlier version of this paper was read at Colorado State University where the audience's comments were beneficial. (shrink)

In this paper I want to suggest that causal and interpretive approaches to epistemology are in tension with one another. Drawing on the work of hermeneutic writers I suggest that epistemological justification is an interpretive process. The possibility of rational justification requires attention to our locatedness within the domain of reasons, into which we have been culturally initiated. The recognition that there is no transcendent processes of rational justification has to be addressed from within this framework and cannot be (...) resolved in a naturalizing way. The turn to hermeneutics in the context of epistemology allows us to reassign a central role to experience within epistemological justification. Here the very features of experience which render problematic its role in empiricist accounts form the basis of its position in hermeneutic ones. This presents us with an immanent conception of rationality, in place of the transcendent conception which so many writers have problematized. (shrink)

In this paper, I examine the possibility of accounting for the rationality of belief-formation by utilising decision-theoretic considerations. I consider the utilities to be used by such an approach, propose to employ verisimilitude as a measure of cognitive utility, and suggest a natural way of generalising any measure of verisimilitude defined on propositions to partial belief-systems, a generalisation which may enable us to incorporate Popper's insightful notion of verisimilitude within a Bayesian framework. I examine a dilemma generated by (...) the decision-theoretic procedure and consider an adequacy condition (immodesty) designed to ameliorate one of its horns. Finally, I argue in a sceptical vein that no adequate verisimilitude measure can be used decision-theoretically. (shrink)

In a recent contribution to this journal, Jim Cheney argues for a postmodern epistemological framework that supports a conception of inquiry as a kind of “conversation” with nature. I examine how Cheney arrives at this metaphor and consider why it might be an appealing one for environmental philosophers. I note how, in the absence of an animistic account of nature, this metaphor turns out to be problematic. A closer examination of the postmodern insights that Cheney employs reveals that it is (...) possible to stress the agency of nature in epistemology without having to draw on the metaphor of conversation. I conclude that this alternative account is not only more plausible, but can probably do the same ethical work as the problematic metaphor of inquiry as conversation. (shrink)

The question as to the appropriate method of epistemic analysis has always been an issue for epistemologists. In recent years, the traditional method utilized in epistemology - conceptual analysis - has come under attack from various perspectives. Yet, often no replacement method is given in its place. In two works, "A Practical Explication of Knowledge" and Knowledge and the State of Nature, Edward Craig proposes a new way of doing epistemology. Craig's epistemic method eschews traditional conceptual analysis in favor of (...) what he calls "conceptual synthesis". He proposes we start not from the finding of necessary and sufficient conditions that match our intuitions; rather we start from considerations on what the concept of knowledge does for us. Though there is much to discuss in Craig proposal, in this paper I explore one aspect - the good informant. It is this aspect that is central to Craig's epistemic method and perhaps most problematic. In this essay, I evaluate this concept by first articulating three initial worries that some have had about the concept. I show that each of the initial worries can be quelled by looking deeper into the features of what Craig's proposal is. I then assess Craig's proposal on its own terms. Instead of looking to counterexamples for possible problems, I look at the concept of a good informant in light of the criteria for an adequate explication. What I hope to show is that while there is much to be sympathetic with in Craig's proposal, there are some open questions that need to be solved in order to say that an adequate explication has been reached.

The history of the relationship between Christian theology and the natural sciences has been conditioned by the initial decision of the masters of the "first scientific revolution" to disregard any necessary explanatory premiss to account for the constituting organization and the framing of naturally occurring entities. Not paying any attention to hierarchical control, they ended-up disseminating a vision and understanding in which it was no longer possible for a theology of nature to send questions in the direction of the (...) experimental sciences, as was done in the past between theology and many philosophically-based thought-systems. Presenting the history of some hinge-periods in the development of the Western-world sciences, this book first sets out to consider the conceptual revolution which has, in the 20th Century, related consciousness, physical laws and levels of organization, in order to show that a new chance existed then for theology. This discourse was invited to revise its language to open it up to the quest for meaning which we find on the periphery of the project of the experimental sciences. The Century-old reflection on the foundations of probability had prepared the ground for the introduction of the concept of information, at first linked to an effort aimed at maximizing the efficiency of electromagnetic communications. Taking the full measure of the questions that information theory poses to the biological sciences, this work attempts to identify the areas of convergence setting the stage for general systems theory, while it also tries to identify the insufficiencies of this recent vision and to highlight the questions left unanswered. Re-reading some of the traditional proofs of God's existence from the order of the world, relying on some pioneering insights of Ludwig von Bertalanffy and Norbert Wiener, the author brings those proofs and insights in contact with the fascinating initial project of cybernetics and the elements of a "mythical" nature which, from its inception, it could never entirely eliminate. This book ends with the confrontation between the conceptually most extended regulation factors in the history of Western thought. It articulates the poetic utopia concerned with an immediate grasp of the world in its "deictic" character with the concurrent one aimed at the domination over matter and energy expressed by technology's driving rational utopia.

A popular conception of probability for many years now has been the relative frequency interpretation, made famous by the work of Reichenbach and von Mises, and more recently by Salmon and others. The frequency view has played important roles of various sorts in virtually every area in epistemology and the philosophy of science, including explanation, causation, the justification of induction, the nature of laws and lawlike statements, and so on. A major attraction of the frequency conception has been its claim (...) to be a strictly empirical view. In this paper we argue that on prima facie grounds the frequency view violates some of our deepest intuitions regarding the notions of probability and possibility. (shrink)

When the atomic theory was revived in the seventeenth century, the atomists faced a problem concerning the status of the laws of nature. On the face of it, the postulation of absolutely hard, rigid, and impenetrable atoms seems to entail the existence of natural necessities and impossibilities: Atoms A and B cannot interpenetrate, so atom A must push atom B when they collide. The properties of compound bodies are to be explained in terms of their “textures” (i.e., the arrangements (...) of their constituent atoms) on the famous lock-and-key model. Once again, it looks as if we have a domain of natural necessities depending on the textures of compound bodies. But the atomists seem to think of the laws of nature as radically contingent, not the sorts of things that could in principle be known a priori. This article seeks to address this tension between what the atomists seem committed to by their matter theory (real necessary connections in nature) and what they in fact say (that all the laws are contingent). In my Atomism (1995) I sought to resolve the tension by appealing to a sharp distinction between the atomists’ metaphysics and their epistemology. On this interpretation, they remain committed to natural necessity, but insist that we can never do Natural Philosophy in the “high priori” manner, by discovering real essences and their necessary connections. Our sciences of nature must remain empirical. Since publication of Atomism, however, this possible solution of the problem has come to seem more doubtful. Reflection on the work of my three “dissenting voices” (Margaret Osler, Peter Anstey and Rae Langton) has forced a radical rethink, focussing on the problematic relation between the intrinsic properties of the atoms and their (dynamic) powers. If there is no discoverable intelligible connection between what the atom is in itself (its intrinsic properties) and what it does (its powers), then my earlier solution will turn out to be untenable.

In this paper I challenge Paolo Palmieri’s reading of the Mach-Vailati debate on Archimedes’s proof of the law of the lever. I argue that the actual import of the debate concerns the possible epistemic (as opposed to merely pragmatic) role of mathematical arguments in empirical physics, and that construed in this light Vailati carries the upper hand. This claim is defended by showing that Archimedes’s proof of the law of the lever is not a way of appealing to a non-empirical (...) source of information, but a way of explicating the mathematical structure that can represent the empirical information at our disposal in the most general way.

This paper examines Duhem’s concept of good sense as an attempt to support a non rule-governed account of rationality in theory choice. Faced with the underdetermination of theory by evidence thesis and the continuity thesis, Duhem tried to account for the ability of scientists to choose theories that continuously grow to a natural classification. I will examine the concept of good sense and the problems that stem from it. I will also present a recent attempt by David Stump to (...) link good sense to virtue epistemology. I will argue that even though this approach can be useful for the better comprehension of the concept of good sense, there are some substantial differences between virtue epistemologists and Duhem. In the light of this reconstruction of good sense, I will propose a possible way to interpret the concept of good sense, which overcomes the noted problems and fits better with Duhem’s views on scientific method and motivation in developing the concept of good sense.

Freedom is first apprehended as the pursuit of an activity which implies the choice to defend a thesis among other possible ones. This translation of the problem of freedom in an articulate language presupposes a complex nervous system and sensory apparatuses which we take for granted. In this study, I try to explore the undergrounds of the problem of freedom along with the suggestion that the notion of coding could enable one to bridge nature and the mind. When organisms invent, (...) are they doing it in a spontaneous manner, inscribing in their hereditary and mnemonic instructions a stochastic contrivance of random accidents, or are they attempting to select among a limited number of schemes endowed with some optimality of functioning? If we consider them as submitted to physical forces, it is to the extent that we make them part of a strategy to extend the "laws" of a nature understood to respond passively. I suggest in this study that the epistemological understanding must regionalize itself and admit a hierarchy of dispositions in relation to the phenomenon of selection. I end by suggesting the pursuit of affirmation instead of negation, as this alone contains the requirement of integration to the knowing subject as well as the form in its act of understanding, without giving it a spontaneist position.

The theory of recognition arises within Hegel's confrontation with epistemological skepticism and aims at responding to the questions raised by modern skepticism concerning the accessibility of the external world, of other minds, and of one's own mind. This is possible to the extent that the theory of recognition is the guiding thread of a critique of the modern foundational theory of knowledge and, at the same time, the point of departure for an alternative approach. In this article I will dwell (...) on six stages of the evolution of Hegel's thought prior to the Phenomenology (1797-1806),stages shed great light on the direction taken by his argumentative strategy. Synthetically, the stages are as follows: 1. Hegel naturalizes the epistemological questions; 2. to do so he critiques foundationalism qua theory of empirical knowledge; 3. and qua theory of epistemic justification; 4. the critique of foundationalism is linked to a critique of the corresponding representationalistic theory of perception; 5. this, in turn, is linked to a critique of the monological theories of self-consciousness and to the development of a model of the rise of self-conscious knowing; 6. finally, Hegel synthesizes these epistemological views in a theory of knowledge qua recognition and in a metaphilosophical theory of philosophical rationality qua self-recognition: knowledge without foundation is thus the condition of possibility of philosophy’s self-justification.

The concept of necessity plays a central role in Kant's philosophy, but seems to lead to severe paradoxes. On the one hand he states: ‘Notwendigkeit und strenge Allgemeinheit sind sichere Kennzeichen einer Erkenntnis a priori’. On the other hand he talks also about ‘notwendig (d. i. nach einer Regel)’, which means ‘necessary according to the empirical natural laws’. However, he never states explicitly the distinction between these two different concepts of necessity. Either Kant's philosophy is inconsistent or we have (...) to assume that he indeed interchanges two different concepts, even if he does not tell us that there is a difference between synthetic apriori necessity and natural necessity. This paper defends the hypothesis of two different necessities and then shows how this strategy makes possible a rational reconstruction of Kant's epistemology. (shrink)

To be a realist about modality, need one claim that more exists than just the various objects and properties that populate the world—e.g. worlds other than the actual one, or maximal consistent sets of propositions? Or does the existence of objects and properties by itself involve the obtaining of necessities (and possibilities) in re? The latter position is now unpopular but not unfamiliar. Aristotle held that objects have essences, and hence necessarily have certain properties. Recently it has been argued that (...) the identity of any property is tied to the natural laws in which it figures, which entails that the occurrence of properties involves the obtaining of nomological necessities ([24], pp. 206-33 and 234-60; [23]; cf. [25] and [6]). Somewhat less recently, Wittgenstein ([28], p. 168) worried that the reality of at least some properties—precise shades of colors being a prime example—involved the obtaining in re of certain impossibilities. This paper argues that Wittgenstein’s worries were right, and not just concerning some properties, but all properties whatever. That there are objects and properties in the world at all, then, amounts to there obtaining modal states of affairs. This argument supplements, rather than replaces, the others. The position on property incompatibility advanced here actually helps defend Aristotelian essentialism against epistemological objections, or so I have argued ([15]). And while this paper’s position on property incompatibility diverges from the idea that a property’s nomic profile is essential to it—more on this in the next section—it is at least compatible with the thought that the necessity involved in the laws of nature enters into ontology at the ground level.

There is a long tradition in philosophy of using a priori methods to draw conclusions about what is possible and what is necessary, and often in turn to draw conclusions about matters of substantive metaphysics. Arguments like this typically have three steps: first an epistemic claim (about what can be known or conceived), from there to a modal claim (about what is possible or necessary), and from there to a metaphysical claim (about the nature of things in the world).

The paper considers Paul Natorp's Kantian reading of Plato's theory of ideas, as developed in his monumental work, Platos Ideenlehre, eine Einführung in den Idealismus (1903, 1921). Central to Natrop's reading are, I argue, the following two claims: (1) Plato's ideas are laws, not things; and (2) Plato's theory of ideas in the first instance a theory about the possibility and nature of thought - in particular cognitive and indeed scientific or explanatory thought - and only as a consequence (...) is it a theory about the nature of reality. Natrop thus argues that Plato's theory of ideas is at its heart a transcendental theory, and that Plato's metaphysics is built on this basis. The paper considers these claims - and their textual basis in Plato - in some detail, and attempts an initial evaluation of their plausibility as a reading of Plato. I am on the whole sympathetic to Natorp's reading, though a proper assessment goes beyond the present paper. The wider interest of this idealist or anti-realist reading of Plato ought to be obvious, especially in view of the commonly accepted assumption these days that both Plato and Aristotle, and indeed the Greeks in general, took realism entirely for granted (see e.g. M. Burnyeat). Natorp argues that this is true of Aristotle, but quite untrue of Plato. But he is quite clear that the idealism he ascribes to Plato is not Berkeleyan or metaphysical idealism, but a certain kind of transcendental or epistemological idealism. Natorp, however, is no uncritical follower of Kant, and the version of trascendental idealism that he ascribes to Plato is, I argue, very different from Kant's. (shrink)

In the problem of the relationship between chemistry and physics, many authors take for granted the ontological reduction of the chemical world to the world of physics. The autonomy of chemistry is usually defended on the basis of the failure of epistemological reduction: not all chemical concepts and laws can be derived from the theoretical framework of physics. The main aim of this paper is to argue that this line of argumentation is not strong enough for eliminate the idea of (...) a hierarchical dependence of chemistry with respect to physics. The rejection of the secondary position of chemistry and the defense of the legitimacy of the philosophy of chemistry require a radically different philosophical perspective that denies not only epistemological reduction but also ontological reduction. Only on the basis of a philosophically grounded ontological pluralism it is possible to accept the ontological autonomy of the chemical world and, with this, to reverse the traditional idea of the ‘superiority’ of physics in the context of natural sciences.

This article sketches a theory of objective probability focusing on "nomic probability", which is supposed to be the kind of probability figuring in statistical laws of nature. The theory is based upon a strengthened probability calculus and some epistemological principles that formulate a precise version of the "statistical syllogism". It is shown that from this rather minimal basis it is possible to derive theorems comprising (1) a theory of direct inference, and (2) a theory of induction. The theory of induction (...) is not of the familiar Bayesian variety, but consists of a precise version of the traditional Nicod Principle and its statistical analogues. (shrink)

Any study of the 'Scientific Revolution' and particularly Descartes' role in the debates surrounding the conception of nature (atoms and the void v. plenum theory, the role of mathematics and experiment in natural knowledge, the status and derivation of the laws of nature, the eternality and necessity of eternal truths, etc.) should be placed in the philosophical, scientific, theological, and sociological context of its time. Seventeenth-century debates concerning the nature of the eternal truths such as '2 + 2 = (...) 4' or the law of inertia turn on the question of whether these truths were created along with nature, or were uncreated and subsisting in God's mind. One's answer to that question has direct consequences for conceptions of the necessity/contingency of mathematical and natural knowledge, how knowledge of such truths is accomplished by humans, and what grounds these truths. In this paper, I review the positions of four successors to Descartes' philosophy on the question of the eternal truths to illustrate how in specific ways that question with its theological, metaphysical, modal, and epistemological dimensions concerned the objectivity and certainty of the discoveries of the new science.

One of the chief concerns of the young Descartes was with what he, and others, termed “physico-mathematics”. This signalled a questioning of the Scholastic Aristotelian view of the mixed mathematical sciences as subordinate to natural philosophy, non explanatory, and merely instrumental. Somehow, the mixed mathematical disciplines were now to become intimately related to natural philosophical issues of matter and cause. That is, they were to become more ’physicalised’, more closely intertwined with natural philosophising, regardless of which species (...) of natural philosophy one advocated. A curious, short-lived yet portentous epistemological conceit lay at the core of Descartes’ physico-mathematics—the belief that solid geometrical results in the mixed mathematical sciences literally offered windows into the realm of natural philosophical causation—that in such cases one could literally “see the causes”. Optics took pride of place within Descartes’ physico-mathematics project, because he believed it offered unique possibilities for the successful vision of causes. This paper traces Descartes’ early physico-mathematical program in optics, its origins, pitfalls and its successes, which were crucial in providing Descartes resources for his later work in systematic natural philosophy. It explores how Descartes exploited his discovery of the law of refraction of light—an achievement well within the bounds of traditional mixed mathematical optics—in order to derive—in the manner of physico-mathematics—causal knowledge about light, and indeed insight about the principles of a “dynamics” that would provide the laws of corpuscular motion and tendency to motion in his natural philosophical system.

In spite of the seminal work A Philosophical Basis of Medical Practice, the debate on the task and goals of philosophy of medicine still continues. From an European perspective it is argued that the main topics dealt with by Pellegrino and Thomasma are still particularly relevant to medical practice as a healing practice, while expressing the need for a philosophy of medicine. Medical practice is a discursive practice which is highly influenced by other discursive practices like science, law and economics. (...) Philosophical analysis of those influences is needed to discern their effect on the goals of medicine and on the ways in which the self-image of man may be changed. The nature of medical practice and discourse itself makes it necessary to include different philosophical disciplines, like philosophy of science, of law, ethics, and epistemology. Possible scenario's of euthanasia and the human genome project in the USA and Europe are used to exemplify how philosopy of medicine can contribute to a realistic understanding of the problems which are related to the goals of medicine and health care.

I begin by arguing that a consistent general naturalism must be understood in terms of methodological maxims rather than metaphysical doctrines. Some specific maxims are proposed. I then defend a generalized naturalism from the common objection that it is incapable of accounting for the normative aspects of human life, including those of scientific practice itself. Evolutionary naturalism, however, is criticized as being incapable of providing a sufficient explanation of categorical moral norms. Turning to the epistemological norms of science itself, particularly (...) those governing the empirical testing of specific models, I argue that these should be regarded as conditional rather than categorical and that, as such, can be given a naturalistic justification. The justification, however, is more cognitive than evolutionary. The historical development of science is found to be a better place for applying evolutionary ideas. After briefly considering the possibility of a naturalistic understanding of mathematics and logic, I turn to the problem of reconciling scientific realism with an evolutionary picture of scientific development. The solution, I suggest, is to understand scientific knowledge as being “perspectival” rather than absolutely objective. I first argue that scientific observation, whether by humans or instruments, is perspectival. This argument is extended to scientific theorizing which is regarded not as the formulation of universal laws of nature but as the construction of principles to be used in the construction of models to be applied to specific natural systems. The application of models, however, is argued to be not merely opportunistic but constrained by the methodological presumption that we live in a world with a definite causal structure even though we can understand it only from various perspectives.

The often-emphasized tension between the singularity of the patient and technical–scientific reproducibility in medicine cannot be resolved without a discussion of the epistemological and methodological status of the human sciences. On the one hand, the rules concerning human action are analogous to the scientific laws of nature. They are de facto sufficiently stable to allow predictions and explanations similar to those of experimental sciences. From this point of view, it is only a trivial truth, but still a methodological irrelevancy, that (...) the patient and the doctor–patient relationship represent an ontologically irreproducible reality. On the other hand, however, one can never exclude that one can fail in the application of "laws" of the human sciences to the individual patient, for such laws are by no means wholly separated from a patient's personal-hermeneutic mediation, and can at any time be revoked by becoming aware of them. This requires a synergistic collaboration of clinical and statistical methods, and shows a methodologically relevant sense in which one cannot disregard the singularity of the patient. The reason for the crucial role of the patient's singularity in medicine is every individual patient's capacity to revoke, in principle, routines and quasi-automatisms, even though the personal mediation by the patient's consciousness de facto changes them in such a small degree that predictions and explanations modeled in experimental science remain possible.

The concept of complexity has become very important in theoretical biology. It is a many faceted concept and too new and ill defined to have a universally accepted meaning. This review examines the development of this concept from the point of view of its usefulness as a criteria for the study of living systems to see what it has to offer as a new approach. In particular, one definition of complexity has been put forth which has the necessary precision and (...) rigor to be considered as a useful categorization of systems, especially as it pertains to those we call living. This definition, due to Robert Rosen, has been developed in a number of works and involves some deep new concepts about the way we view systems. In particular, it focuses on the way we view the world and actually practice science through the use of the modelling relation. This mathematical object models the process by which we assign meaning to the world we perceive. By using the modelling relation, it is possible to identify the subjective nature of our practices and deal with this issue explicitly. By so doing, it becomes clear that our notion of complexity and especially its most popular manifestations, is in large part a product of the historical processes which lead to the present state of scientific epistemology. In particular, it is a reaction to the reductionist/mechanistic view of nature which can be termed the Newtonian Paradigm. This approach to epistemology has dominated for so long that its use as a model has become implicit in most of what we do in and out of science. The alternative to this approach is examined and related to the special definition of complexity given by Rosen. Some historical examples are used to emphasize the dependence of our view of what is complex in a popular sense on the ever changing state of our knowledge. The role of some popular concepts such as chaotic dynamics are examined in this context. The fields of artificial life and related areas are also viewed from the perspective of this rigorous view of complexity and found lacking. The notion that in some way life exists at the edge of chaos is examined from the perspective of the second law of thermodynamics given by Schneider and Kay. Finally, the causal elements in complex systems are explored in relation to complexity. Rosen has shown that a clear difference in causal relations exists between complex and simple systems and that this difference leads to a uniquely useful definition of what we mean by living. Rosen makes it very clear that the class of systems which are complex is a much larger class than those which we call living. For that reason, the focus of this review will be on complexity as a stepping stone towards the deeper question of what makes a system alive. (shrink)

The fact that much of our knowledge is gained through the testimony of others challenges a certain form of epistemic individualism. We are clearly not autonomous knowers. But the discussion surrounding testimony has maintained a commitment to what I have elsewhere called epistemic agent individualism. Both the reductionist and the anti-reductionist have focused their attention on the testimony of individuals. But groups, too, are sources of testimony - or so I shall argue. If groups can be testifiers, a natural (...) question to ask is whether our beliefs based on the testimony of groups are ever justified and whether such a justification is to be conferred inferentially or non-inferentially. I consider and dismiss the possibility of extending an anti-reductionist account of justification to our group testimonial beliefs. I also argue against a version of reductionism that would have our group testimonial beliefs justified only in so far as we were able to monitor the trustworthiness of members of the group. However, there are forms of reductionism that can be extended to make sense of the justification of our group testimonial beliefs. There are mechanisms for monitoring the trustworthiness and competency of a group (rather than its members) and, further, a variety of background beliefs allow us to assess the testimony of a group for reliability.

This paper evaluates the claim that it is possible to use nature’s variation in conjunction with retention and selection on the one hand, and the absence of ultimate groundedness of hypotheses generated by the human mind as it knows on the other hand, to discard the ascription of ultimate certainty to the rationality of human conjectures in the cognitive realm. This leads to an evaluation of the further assumption that successful hypotheses with specific applications, in other words heuristics, seem to (...) have a firm footing because they were useful in another context. I argue that usefulness evaluated through adaptation misconstrues the search for truth, and that it is possible to generate talk of randomness by neglecting aspects of a system’s insertion into a larger situation. The framing of the problem in terms of the elimination of unfit hypotheses is found to be unsatisfying. It is suggested that theories exist in a dimension where they can be kept alive rather than dying as phenotypes do. The proposal that the subconscious could suggest random variations is found to be a category mistake. A final appeal to phenomenology shows that this proposal is orphan in the history of epistemology, not in virtue of its being a remarkable find, but rather because it is ill-conceived. (shrink)

Jon Elster worries about the explanatory power of the social sciences. His main concern is that they have so few well-established laws. Elster develops an interesting substitute: a special kind of mechanism designed to fill the explanatory gap between laws and mere description. However, his mechanisms suffer from a characteristic problem that I will explore in this article. As our causal knowledge of a specific problem grows we might come to know too much to make use of an Elsterian mechanism (...) but still lack a law. We might then find ourselves in the paradoxical position of knowing more relevant causal truths about the phenomenon we are interested in than we did before, but being able to explain less. If this possibility is realized in social science settings, as I argue it might well be, Elster?s mechanistic account is threatened. Moreover, even if the possibility is rarely realized in that way, it raises, simply as a possibility, a conceptual problem with Elster?s mechanistic framework. (shrink)

Bernard Bolzano's philosophy of mind is closely related to his metaphysical conceptions of substance, adherence and force. Questions as to how the mind is working are treated in terms of efficient (causal) faculties producing simple and complex representations, conclusive and non-conclusive judgments, and meta-representational attitudes such as believing and knowing. My paper outlines the proximity of Bolzano's account of "mental forces" to contemporary accounts of faculty psychology such as Modularity Theory and Simple Heuristics. While the modularist notions of domain specificity (...) and encapsulated mental faculties align with Bolzano's allotment of domain specific tasks to correspondingly specified psychological forces (e.g. judging to "judgmental force", inferring to "inferential force" etc.), the emphasis of Simple Heuristics on accurate "fast and frugal" processes aligns with Bolzano's views regarding cognitive resources and the importance of epistemic economy. The paper attempts to show how Bolzano's metaphysics of mind supposes a conception of bound rationality that determines his epistemology. Combining the rationalist concern for epistemic agent responsibility in the pursuit of knowledge with a strong confidence in the reliability of causal processes to generate the right beliefs, his epistemology shows close affinities with contemporary Virtue Epistemology. According to Virtue Epistemology, knowledge requires that true beliefs be generated by reliable processes typical of a virtuous character. The thesis that Bolzano anticipates virtue epistemological considerations is corroborated by his discussion of heuristic principles that set the norms for the acquisition of knowledge. The paper explores possible relations between such principles and the presumed low-level heuristics of cognitive processes. (shrink)

In this paper which consists of two parts (Teil I and Teil II) we champion Diophantus of Alexandria and Isabella BaÅ¡makova against Norbert Schappacher. In two publications ([Schappacher 1998a] and [Schappacher 1998b]) he puts forward inter alia two propositions: Questioning Diophantus’ originality he considers affirmatively the possibility that the Arithmetica are the joint work of a team of authors like Bourbaki. And he calls BaÅ¡makova’s claim (in [BaÅ¡makova 1972]) that Diophantus uses negative numbers, a nonsense , reproaching her for (...) her thoughtlessness . Teil I: First, we disprove Schappacher’s Bourbaki thesis. Second, we investigate the semantic meaning and historical significance of Diophantus’ keywords $ λvarepsilon tildeιψιζ and ὕπαρξιζ. Next, we discuss Schappacher’s epistemology of the history of mathematics and defend BaÅ¡makova’s methods. Finally we analyse in detail three problems from Diophantus’ Arithmetica (and their solutions) given by Thomas Heath and Helmuth Gericke as proof of the their claim that Diophantus did not use negative numbers. Teil II: In this Part, we give 33 places where Diophantus uses negative quantities as intermediate results; they appear as differences a − b of positive rational numbers, the subtrahend b being bigger than the minuend a; they each represent the (negative) basis ( πλvarepsilonυρacuteα ) of a square number ( τvarepsilonτρacuteαγω ν o ζ ), which is afterwards computed by the formula (a - b) 2 = a 2 + b 2 - 2ab $ . Finally, we report how the topic Diophantus and the negative numbers has been dealt with by translators and commentators from Maximus Planudes onwards.

Why believe Hume's Dictum, according to which there are, roughly speaking, no necessary connections between wholly distinct entities? Schaffer ('Quiddistic Knowledge', 2009) suggests that HD, at least as applied to causal or nomological connections, is motivated as required by the best account of (the truth) of counterfactuals---namely, a similarity-based possible worlds account, where the operative notion of similarity requires 'miracles'---more specifically, worlds where entities of the same type that actually exist enter into different laws. The main cited motivations for such (...) an account of similarity are first, that some salient contexts presuppose CF asymmetry, and second, that accounts of CFs failing to presuppose CF asymmetry are epistemologically problematic, such that under conditions of determinism, the variations in initial micro-conditions needed to implement a given counterfactual antecedent would result in so many changes to macro-states that evaluation of CFs would be rendered practically impossible. Against the first reason, I argue that no non-artificial contexts presuppose CF asymmetry; against the second, I observe that such micro-variation is compatible, in principle, with significant similarity as regards macroscopic states of affairs---enough, in particular, to allow CFs to be appropriately evaluated.

Physics, at the various stages of knowlege, presents itself as an objective description of the natural world, and makes use, for this purpose, of rational concepts, proposed as universal. However, these concepts are built by human thought in particular subjective and historical situations, and are submitted to transformation processes. Is it possible to conciliate these two points of views, the objective and the relative ones? And how to conceive such transforrnations, uncler the sign of intelligibility, of this science and (...) of history as well? (shrink)

Barry Stroud's work has had a profound impact on a very wide array of philosophical topics, including epistemological skepticism, the nature of logical necessity, the interpretation of Hume, the interpretation of Wittgenstein, the possibility of transcendental arguments, and the metaphysical status of color and value. And yet there has heretofore been no book-length treatment of his work. The current collection aims to redress this gap, with 13 essays on Stroud's work by a diverse group of contributors including some of (...) his most distinguished interlocutors and promising recent students. All but one essay is new to this volume. -/- The essays cover a range of topics, with a particular focus on Stroud's treatments of skepticism and subjectivism. There are also chapters on Stroud's views on meaning and rule-following, on Hume on personal identity, and on the role of desires in the explanation of action. Despite the diversity, the essays are unified by the thematic unity in Stroud's own writings. Stroud approaches every philosophical problem by attempting to get as clear as possible on the nature and source of that problem. He aims to determine what kind of understanding philosophical questions are after, and what the prospects for achieving that understanding might be. This theme--of the nature and possibility of philosophical understanding--is introduced in the opening essay of this volume and recurs in different ways throughout the remaining chapters. -/- In recent years, there has been a renewed interest in the philosophy of philosophy. As these essays show, one important source of insight on this subject is the thought of Barry Stroud, for whom pursuit of the philosophy of philosophy has always been indistinguishable from pursuit of philosophy as such.

The ancient world witnessed a meaningful transition in the conception of human thought and belief. What some have called the “discovery” of the mind can also be understood as a release from dependence on oracular wisdom and mythological explanation, made possible by the invention of more reliable and democratic methods for discovering and explaining truths. During roughly the same epoch, Hellenic sport distinguished itself by developing objective mechanisms for selecting single winners from varied pools of contestants. Is there a connection? (...) Following the general thesis that sport is an expression of thehuman desire to know, this paper will explore the epistemological nature of the earliest forms Hellenic athletics. I begin by interpreting the funeral games depicted in Homer’s Iliad as an unbiased, publicly monitored means for settling questions of social honor. I then consider the ancient Olympic games, arguing that their religious foundations motivated a new focus on objective and reliable methods for selecting single winners who could be symbolically sacrificed to the god. In both manifestations, athletic games are used to objectively answer important questions about merit. Eventually, competitive methods of truth‐seeking would become commonplace in Western thought. By examining early the origins of Greek sport in this light, however, Olympia may be identified as a key source of epistemological testing methods, and sport itself may be characterized fundamentally as a search for knowledge.

In Moral Knowledge? New Readings in Moral Epistemology, editors Walter Sinnott-Armstrong and Mark Timmons bring together eleven specially commissioned essays by distinguished moral philosophers exploring the nature and possibility of moral knowledge. Each essay represents a major position within the exciting field of moral epistemology in which a proponent of the position presents and defends his or her view and locates it vis-a-vis competing views. The authors include established philosophers such as Peter Railton, Robert Audi, Richard Brandt, and Simon (...) Blackburn, as well as newer voices in the field. Topics covered include moral skepticism, moral truth, projectivism, contractarianism, coherentism, feminist views, quasi-realism, and pragmatism. The lively and clear selections do not presuppose specialized knowledge of philosophy, and the philosophical vocabulary used throughout the anthology is uniform, in order to facilitate understanding by those not familiar with the field. The first chapter includes a sustained critical discussion of the major views represented in the following chapters, thereby furnishing beginning students with appropriate background to understand the selections. The volume is further enhanced by an index and an extensive bibliography. An excellent text for undergraduate and graduate courses, Moral Knowledge provides the most up-to-date work on moral knowledge and justification. (shrink)

What is our epistemic access to metaphysical modality? Timothy Williamson suggests that the epistemology of counterfactuals will provide the answer. This paper challenges Williamson's account and argues that certain elements of the epistemology of counterfactuals that he discusses, namely so called background knowledge and constitutive facts, are already saturated with modal content which his account fails to explain. Williamson's account will first be outlined and the role of background knowledge and constitutive facts analysed. Their key role is to restrict our (...) imagination to rule out irrelevant counterfactual suppositions. However, background knowledge turns out to be problematic in cases where we are dealing with metaphysically possible counterfactual suppositions that violate the actual laws of physics. As we will see, unless Williamson assumes that background knowledge corresponds with the actual, true laws of physics and that these laws are metaphysically necessary, it will be difficult to address this problem. Furthermore, Williamson's account fails to accommodate the distinction between conceivable yet metaphysically impossible scenarios, and conceivable and metaphysically possible scenarios. This is because background knowledge and constitutive facts are based strictly on our knowledge of the actual world. Williamson does attempt to address this concern with regard to metaphysical necessities – as they hold across all possible worlds – but we will see that even in this case the explanation is questionable. These problems, it will be suggested, cannot be addressed in a counterfactual account of the epistemology of modality. The paper finishes with an analysis of Williamson's possible rejoinders and some discussion about the prospects of an alternative account of modal epistemology. (shrink)

In this paper I propose a naturalist account of the Buddhist epistemological discussion of _svasavitti_ ('self-awareness', 'self-cognition') following similar attempts in the domains of phenomenology and analytic epistemology. First, I examine the extent to which work in naturalized epistemology and phenomenology, particularly in the areas of perception and intentionality, could be profitably used in unpacking the implications of the Buddhist epistemological project. Second, I argue against a foundationalist reading of the causal account of perception offered by (...) Dignga and Dharmakīrti. Finally, I argue that it is possible to read Dignga's (and following him Dharmakīrti's) treatment of _svasamvitti_ as offering something like a phenomenological account of embodied self-awareness.

This essay identifies two different methodological strategies used by the proponents of anarchism. In what is termed the "ontological" approach, the rationale for anarchism depends on a particular representation of human nature. That characterization of "being" determines the relation between the individual and the structures of social life. In the alternative approach, the epistemological status of "representation" is challenged, leaving human subjects without stable identities. Without the possibility of stable human representations, the foundations underlying the exercise of institutional power (...) can be challenged. This epistemological discussion is traced from Max Stirner to the twentieth-century movement known as poststructuralism. (shrink)

The philosophy of modality investigates necessity and possibility, and related notions--are they objective features of mind-independent reality? If so, are they irreducible, or can modal facts be explained in other terms? This volume presents new work on modality by established leaders in the field and by up-and-coming philosophers. Between them, the papers address fundamental questions concerning realism and anti-realism about modality, the nature and basis of facts about what is possible and what is necessary, the nature of modal knowledge, (...) modal logic and its relations to necessary existence and to counterfactual reasoning. The general introduction locates the individual contributions in the wider context of the contemporary discussion of the metaphysics and epistemology of modality. (shrink)

The paper raises two questions, which seem central to understanding Kant's transcendental epistemology in the first Critique. First, Kant claims that the conditions for the possibility of experience are also conditions for the possibility of the objects of experience (A158/B197). Here the notion of an object is not conceived from the divine standpoint ('the view from nowhere') and is in some sense relativized to experience. But in what sense? Is the notion of an object relativized to one specific (...) kind of experience, human experience? Or is it relativized only to any possible experience? Second, in what sense is Kant's transcendental epistemology a priori? Is it a priori in the strong sense that its starting-point - the notion of experience in the question 'How is experience possible?' - is a priori? Or is it a priori only in the weak sense that, while the notion of experience is obtained empirically, a priori reasoning is required to establish how experience is possible? It has recently been argued (by Patricia Kitcher, Kant's Transcendental Psychology) that (a) the results that Kant wants to establish transcenden-tally about objects are relative to one specific kind of experience, human experience, and (b) Kant's transcendental epistemology is a priori only in the weak sense that the reasoning is a priori, while the starting-point is empirical. These claims are indeed crucial to Kitcher's overall aim of naturalizing Kant's transcendental epistemology. The aim of the paper is to resist both claims. I argue that Kant's notion of an object of experience is the notion of an object of any possible experience, not the notion of an object of one specific kind of experience, human experience. It follows, I argue, that Kant's transcendental epistemology is a priori in the strong sense that its starting-point is a priori. If we deny strong apriority, we fail to account for Kant's move from the nature of experience to the nature of empirical reality: empirical reality as such, not empirical reality as experienced by a particular variety of creatures capable of experience. The upshot is that, for better or worse, Kant's transcendental epistemology cannot be naturalized. (shrink)

Recent psychological research on the connection between culture and thought could have dire consequences for the idea that there are objective standards of reasoning and that meaningful cross-cultural discussion is possible. The problems are particularly acute if research shows that the Law of Noncontradiction (LNC) is not a universal of folk epistemology. It is extremely difficult to provide a non-circular justification for the LNC, and yet the LNC seems to act as a basic standard for reasoning in the West. If (...) non-Western cultures do not believe the LNC holds, then meaningful cross-cultural discussion and debate will be very difficult, to say the least. In this paper it is argued that the distinction between belief and acceptance is important in analyzing cross-cultural studies on the way people reason. Studies conducted by Richard Nisbett and Kaiping Peng concerning differences between East Asians and Westerners are analyzed. The distinction between belief and acceptance is used to demonstrate that the empirical data currently available fail to show that the LNC is not a universal of folk epistemology. A brief proposal for further research is presented. (shrink)

In this essay I take issue with entrenched conceptions of individual autonomy for how they block understandings of the implications of rape in patriarchal cultures both 'at home' and in situations of armed conflict. I focus on human vulnerability as it manifests in sedimented assumptions about violence against women as endemic to male-female relations, thwarting possibilities of knowing the specific harms particular acts of rape enact well enough to render intelligible their far-reaching social-political-moral implications. Taking my point of departure from (...) Debra Bergoffen's call for 'a new epistemology of rape', I consider what such a call can amount to within an instituted social imaginary where male domination and female subordination are taken for granted—naturalized.

Visual thinking -- visual imagination or perception of diagrams and symbol arrays, and mental operations on them -- is omnipresent in mathematics. Is this visual thinking merely a psychological aid, facilitating grasp of what is gathered by other means? Or does it also have epistemological functions, as a means of discovery, understanding, and even proof? By examining the many kinds of visual representation in mathematics and the diverse ways in which they are used, Marcus Giaquinto argues that visual thinking in (...) mathematics is rarely just a superfluous aid; it usually has epistemological value, often as a means of discovery. Drawing from philosophical work on the nature of concepts and from empirical studies of visual perception, mental imagery, and numerical cognition, Giaquinto explores a major source of our grasp of mathematics, using examples from basic geometry, arithmetic, algebra, and real analysis. He shows how we can discern abstract general truths by means of specific images, how synthetic a priori knowledge is possible, and how visual means can help us grasp abstract structures. Visual Thinking in Mathematics reopens the investigation of earlier thinkers from Plato to Kant into the nature and epistemology of an individual's basic mathematical beliefs and abilities, in the new light shed by the maturing cognitive sciences. Clear and concise throughout, it will appeal to scholars and students of philosophy, mathematics, and psychology, as well as anyone with an interest in mathematical thinking. (shrink)

This article investigates the place of postmodernism in sociology today by making a distinction between its epistemological and empirical forms. During the 1980s and early 1990s, sociologists exposited, appropriated, and normalized an epistemological postmodernism that thematizes the tentative, reflective, and possibly shifting nature of knowledge. More recently, however, sociologists have recognized the potential of a postmodern theory that turns its attention to empirical concerns. Empirical postmodernists challenge classical modern concepts to develop research programs based on new concepts like time-space reorganization, (...) risk society, consumer capitalism, and postmodern ethics. But they do so with an appreciation for the uncertainty of the social world, ourselves, our concepts, and our commitment to our concepts that results from the encounter with postmodern epistemology. Ultimately, this article suggests that understanding postmodernism as a combination of these two moments can lead to a sociology whose epistemological modesty and empirical sensitivity encourage a deeper and broader approach to the contemporary social world.

This article draws out an epistemological tension implicit in Cosmides and Tooby's conception of evolutionary psychology. Cosmides and Tooby think of the mind as a collection of functionally individuated, domain-specific modules. Although they do not explicitly deny the existence of domain-general processes, it will be shown that their methodology commits them to the assumption that only domain-specific cognitive processes are capable of producing useful outputs. The resultant view limits the scope of biologically possible cognitive accomplishments and these limitations, it will (...) be argued, are such as to deny us epistemic capacities that evolutionary psychology presupposes in its pursuit of an objective, comprehensive account of human nature.

The article investigates the sceptical challenge from an information-theoretic perspective. Its main goal is to articulate and defend the view that either informational scepticism is radical, but then it is epistemologically innocuous because redundant; or it is moderate, but then epistemologically beneficial because useful. In order to pursue this cooptation strategy, the article is divided into seven sections. Section 1 sets up the problem. Section 2 introduces Borel numbers as a convenient way to refer uniformly to (the data that individuate) (...) different possible worlds. Section 3 adopts the Hamming distance between Borel numbers as a metric to calculate the distance between possible worlds. In Sects. 4 and 5, radical and moderate informational scepticism are analysed using Borel numbers and Hamming distances, and shown to be either harmless (extreme form) or actually fruitful (moderate form). Section 6 further clarifies the approach by replying to some potential objections. In the conclusion, the Peircean nature of the overall approach is briefly discussed. (shrink)

The present paper is guided by the belief that Edmund Husserl’s concept of noema can be significantly enriched when considered in light of extreme epistemological instances. These include the phenomena of the absurd and nonsense, but also intentional conflict and cases of consciousness directed to contradictory objects. The paper shows that the noema, when experienced in such a context, exhibits interesting characteristics that are rather difficult to note in other circumstances. The paper consists of five sections. The first interprets and (...) relates concepts from Logical Investigations to those from Ideas I. The second section discloses the noematic ability to assemble senses for which there is no corresponding object. The third section stresses that the noema must, in some instances, be able to comprise two separate structures of senses through which two different objects are meant. In the fourth section, all of these characteristics are shown to be restricted by the concept of nonsense and the laws of meaning-compounding. In this way, the noema is clarified as “possibly thinkable content.” Finally, in Sect. 5, this idea is brought into dialogue with the most significant interpretations of the noema. (shrink)

Epistemologies and research methods are not free of metaphysics. This is to say that they are both, supported by (or presumed by), and support (or presume) fundamental ontologies. A discussion of the epistemological foundations of "multimethod" research in the social sciences—in as much as such research claims to unearth "causal" relations—therefore cannot avoid the ontological presuppositions or implications of such a discussion. But though there isn’t necessarily a perfect correspondence between ontology, epistemology, and methodology, they do constrain each other. As (...) such it is possible to make methodological choices that are at odds with one’s (implicit) ontology or argue from an ontology that is inconsistent one’s choice of methods.Yet lack of recognition of this fact has hampered methodological discussions in political science, especially with respect to the discussion on the merits of multimethod research. The ontology implicitly accepted in such discussions is "reductionist" and "regularist," that is, one that respectively defines causes in terms of noncausal relations and states of affair and affirms that such noncausal relations are regularities in nature. This article will argue that any attempt to fit "multimethod" research (where "multimethod" signifies some combination of inferential statistics and case studies) within this narrow ontology is destined to fail since such a metaphysics logically cannot accord case studies a necessary or sufficient role in the in the establishment of causal relations. However, there are metaphysical positions within the ambit of an empiricist philosophy of science that can accommodate multiple methods without contradiction. The article discusses two such ontologies and suggests ways in which they might allow the establishment of a coherent epistemological foundation for multimethod research, however, within a decidedly empiricist philosophy of science.

Epistemology answers to a daunting variety of senses in the humanities and the social sciences. Even when we restrict our attention to epistemology as it is understood in contemporary Anglo- American philosophy, the only uncontroversial claim we can make is that epistemology is an attempt to make sense of the possibility, nature, and limits of human intellectual achievement. Typically, the epistemologist does this by trying to illuminate the difference between knowledge and opinion, or the difference between good reasoning and (...) poor reasoning. This project is distinct from merely giving a descriptive account of what people claim to know or to believe reasonably. Instead, epistemologists try to understand what it is really to know or really to believe reasonably, even if people routinely fail to know or are frequently irrational. Moving beyond the descriptive details of knowledge or belief formation to what people ought to believe is a normative philosophical enterprise. Construed one way, epistemology aims to understand general and ubiquitous elements of human inquiry, such as perceptual knowledge or inductive inference. This project has sometimes.. (shrink)

Recent responses to evidential formulations of the argument from evil have emphasized the possible limitations on human cognitive access to the goods and evils that might be connected with various wordly states of affairs. This emphasis, I argue, is a twin-edged sword, as it imperils a popular form of natural theology. I conclude by arguing that the popularity enjoyed by Reformed Epistemology does not detract from the significance of this result, since Reformed Epistemology is not inimical to natural (...) theology, and Reformists themselves concede the usefulness of theistic proofs.

Internalism and Epistemology is a powerful articulation and defense of a classical answer to an enduring question: What is the nature of rational belief? In opposition to prevailing philosophical fashion, the book argues that epistemic externalism leads, not just to skepticism, but to epistemic nihilism - the denial of the very possibility of justification. And it defends a subtle and sophisticated internalism against criticisms that have widely but mistakenly been thought to be decisive. Beginning with an internalist response to (...) the Gettier problem, the authors deal with the problem of the connection to truth, stressing the distinction between success and rationality as critical to its resolution. They develop a metaregress argument against externalism that has devastating consequences for any view according to which epistemic principles are contingent. The same argument does not, they argue, affect the version of internalism they espouse, since its epistemic principles are analytic and knowable a priori. The final chapter addresses the problem of induction and shows that its solution turns critically on the distinction between success and rationality - the very distinction that lies at the heart of the dispute between internalists and externalists. Provocative, probing, and deliberately unfashionable, Internalism and Epistemology is a ringing defense of internalism that will interest specialists and students alike. It is essential reading for anyone who suspects that rumors of the death of traditional epistemology have been greatly exaggerated. (shrink)

This work develops an epistemology of measurement, that is, an account of the conditions under which measurement and standardization methods produce knowledge as well as the nature, scope, and limits of this knowledge. I focus on three questions: (i) how is it possible to tell whether an instrument measures the quantity it is intended to? (ii) what do claims to measurement accuracy amount to, and how might such claims be justified? (iii) when is disagreement among instruments a sign of error, (...) and when does it imply that instruments measure different quantities? Based on a series of case studies conducted in collaboration with the US National Institute of Standards and Technology (NIST), I argue for a model-based approach to the epistemology of physical measurement. To measure a physical quantity, I argue, is to estimate the value of a parameter in an idealized model of a physical process. Such estimation involves inference from the final state (‘indication’) of a process to the value range of a parameter (‘outcome’) in light of theoretical and statistical assumptions. Contrary to contemporary philosophical views, measurement outcomes cannot be obtained by mapping the structure of indications. Instead, measurement outcomes as well as claims to accuracy, error and quantity individuation can only be adjudicated relative to a choice of idealized modelling assumptions. (shrink)

Kant's views on the epistemological status of physical science provide an important example of how a philosophical system can be applied to understand the foundation of scientific theories. Michael Friedman has made considerable progress towards elucidating Kant's philosophy of science; in particular, he has argued that Kant viewed Newton's law of universal gravitation as necessary for the possibility of experiencing what Kant called true motion, which is more than the mere relative motion of appearances but is different from Newton's (...) concept of absolute motion. In this context, Friedman has provided an account of how Kant must have viewed Newton's supposed derivation of universal gravitation from Kepler's laws, based on, among other things, Kant's claim that Newton really needed to make extra assumptions in order to derive universal gravitation. In this paper, I argue that Friedman's account is incomplete for three reasons. First, Friedman has overlooked an important aspect of how Newton's third law is applied in the relevant sections of the Principia; as a result, Friedman's account partially misconstrues the relation between the planetary phenomena and the theory of universal gravitation. Second, his account fails to account for Kant's apparent belief that Kepler's laws are only empirically-based rules, even though they seem to be necessary for the derivation of universal gravitation and hence also necessary for Kant's own definition of true motion. Third, Friedman has overlooked some remarks by Kant that indicate that Kant thought the crucial properties of universal gravitation could be known without reference to the empirically determined motions of the planets and hence seemingly without any help from Newton.

‘Naturalized’ philosophers of mind regularly appeal to the empirical psychological literature in support of the ‘theory-theory’ account of the natural epistemology of mental state ascription (to self and others). It is argued that such appeals are not philosophically neutral, but in fact presuppose the theory-theory account of mental state ascription. It is suggested that a possible explanation of the popularity of the theory-theory account is that it is generally assumed that alternative accounts in terms of introspection (and simulation) presuppose (...) a discredited ‘inner ostensive definition’ account of the meaning of mental state terms. However, the inner ostensive definition account is not the only alternative to the theory-theory account of the meaning of mental state terms, and commitment to a theory-theory account of the meaning of mental state terms does not mandate commitment to a theory-theory account of the epistemology of mental state ascription.

I propose a few epistemological and methodological reflexions to account for intercultural daily communication. These reflexions emerged during a sociological research in Mendoza, Argentina, with Huarpes Indigenous students at the University of Cuyo. I observed that Indigenous people became quasi ethnographers of diverse environments. To make intelligible their classmates’ behavior, and to account for their own behavior, Huarpes follow, in diverse environments and interactions, public rules of meaning. The objective of this paper is twofold: (a) to stress the methodological scope (...) of ordinary communication and ordinary reasoning in order to study understanding between people from different groups and categories, and (b) to contest a kind of pessimist standpoint in social sciences and philosophy according to which the use of ordinary language reduces possibilities for understanding. Interviews, participant observation in natural situations, and a review of literature about language and understanding are the basis of this paper. (shrink)

This paper is concerned with the debate in evolutionary epistemology about the nature of the evolutionary process at work in the development of science: whether it is Darwinian or Lamarckian. It is claimed that if we are to make progress through the many arguments that have grown up around this issue, we must return to an examination of the concepts of change and evolution, and examine the basic kinds of mechanism capable of bringing evolution about. This examination results in two (...) kinds of processes being identified, dubbed direct and indirect, and these are claimed to exhaust all possibilities. These ideas are then applied to a selection of the debates within evolutionary epistemology. It is shown that while arguments about the pattern and rate of evolutionary change are necessarily inconclusive, those concerning the origin of novel variations and the mode of inheritance can be resolved by means of the distinctions made here. It is claimed that the process of selection in the evolution of science can also be clarified. The conclusion is that the main process producing the evolution of science is a direct or Lamarckian one although, if realism is correct, an indirect or Darwinian process plays a vital role.

Philosophers, Henri Bergson once observed, "seem to philosophize as if they were sealed in the privacy of their study and did not live on a planet surrounded by the vast organic world of animals, plants, insects, and protozoa." Providing a solid overview of ecological philosophy and original insights into this developing field, Minding Nature focuses on some of the most influential thinkers who, in fact, have emphasized our natural relations to the earth, our social creations, and each other. Combining (...) philosophy, ecology, and political theory, chapters thoroughly examine, critique, and build upon the ideas of such luminaries as Thomas Hobbes, Martin Heidegger, Ernst Bloch, Hannah Arendt, Herbert Marcuse, Barry Commoner, Rachel Carson, and Jurgen Habermas, among others. Each thinker considered has contributed significantly to both contemporary discussion and historical understanding of political, epistemological, or social aspects related to nature and, with several exceptions, stimulated constructive dialogue within progressive, democratic, and radical left circles. By challenging the notion that conservation is inherently politically conservative or that our oikos (home) must be rendered uniformly economic where ecology is concerned, they enable us to rethink the possibility of creating a more democratic and ecological society.

The main aim of this paper is to investigate what becomes of normativity in naturalistic epistemologies. What particular stand a given naturalistic epistemology takes on normativity will depend both on what it thinks is wrong with traditional epistemology and on what level of normativity is at stake. I propose a tentative typology of possible attitudes towards normativity from within naturalistic epistemology. In section I, I give a brief presentation of traditional epistemology, stressing the dimensions of this approach that may appear (...) problematic to naturalists. In section II, I present and discuss the naturalist project in its radical form, as personified by Quine, who questions not only the way in which traditional epistemology proceeds in order to attain its objectives, but also the validity of these objectives. The last two sections concentrate on more moderate versions of naturalism. Section III investigates the various possible roles that may be assigned to psychology in these moderate forms of naturalism and the ensuingconsequences vis-a-vis the problem of normativity. In section IV, I distinguish between two levels of normativity in epistemology, what I call the normativity of means and the normativity of ends and I discuss the prospects of a naturalization of epistemic ends.

This paper examines the question whether foundational epistemology (“FE”) can be replaced by naturalized epistemology (“NE”). First, it argues that Quine's defense of NE is inadequate since it is only based on arguments showing the impossibility of the logical empiricist version of FE rather than on arguments for the impossibility of FE as such. Second, it proposes that a more promising argument for the impossibility of FE can be found in the Münchhausen-trilemma which aims at showing that ultimate foundations (and, (...) hence, FE) are unattainable. However, Karl-Otto Apel has shown that this trilemma is unconclusive since it uncritically presupposes the premise that all argumentation is deductive in nature. Apel's argument implies that FE is possible if and only if it is possible to devise a non-deductive foundation (“NDF”). It is argued, however, that the possibility of NDF cannot be demonstrated. This leads to a situation called the Multatuli-dilemma: we cannot prove the possibility of ultimate foundations nor can we prove the impossibility of ultimate foundations. This dilemma shows that the discussion about the possibility of FE is pointless. Thus, it suggests that it is legitimate to replace FE by NE. Barry Stroud and Henri Lauener, however, argue that this replacement is not feasible since NE is not capable of refuting scepticism (Stroud) or justifying methodological rules (Lauener). But these objections are shown to be mistaken: First, epistemological scepticism is practically impossible and, hence, does not pose a serious threat to NE. Second, NE is capable of justifying methodological norms if and only if it makes use of so-called internal justifications. Thus, the final conclusion of this paper is that FE can be replaced by NE.

What is the relation between philosophical analysis and sociological method? Sociology has traditionally looked to Philosophy to provide either an indubitable epistemic foundation for its practices or alternatively to legislate invariant criteria of scientificity which might guide the social sciences in questions of methodology. But has Philosophy itself such an autonomy from the developing knowledge domains of the different sciences,natural and social? A structural analysis of philosophic discourse in the twentieth century reveals as a key element of recent philosophic'al (...) thought a central anthropologism. This study traces the rupture in philosophic thought which has occurred with the dissolution and collapse of classical epistemology and the emergence in turn of a radically new mode of philosophizing based on a recognition of the centrality of social reality to ontological judgement and epistemological critique. Just as the analytic epistemOlogy of the seventeenth century can be seen as an accommodation by Philosophy to the emergence and development of the empirical natural sc~ences, so the appearance of 'conversational' epistemology can be viewed as Philosophy's attempt to think'the implications for the nature of knowledge-in-general of the emergence and subsequent development of the social sciences at the end of the nineteenth century. The key theoretical instance which demarcates classical epistemology fram the anthropologistic philosophy since the 1920's is its inability to accommodate the category of intersubjectiv:itJY successfully within its egological structure. Contemporary philosophy, phenomenological, analytical, pragmatist and marxist, is forced to grapple with the new awareness of man's essential sociality. This has profound implications for epistemology. The question of the relationship of philosophical analysis to sociological method must be re-addressed in the light of the revealed epistemic proximity of the two disciplines. What sort of philosophical critique, we ask, is possible and appropriate in an age of sociological reason and historical method? (shrink)

In this thesis I provide an interpretation of Kant's theories of knowledge, nature, and being in order to argue that Kant's ontology is a productive ontology: it is a theory of being that includes a notion of production. I aim to show that Kant's epistemology and philosophy of nature are based on a theory of being as productivity. The thesis contributes to knowledge in that it considers in detail Kant's ontology and theory of being, topics which have generally been ignored (...) or misunderstood. In arguing for Kant's productive ontology, I argue against Heidegger's interpretation of Kant, which states that Kant understands being as "produced permanent presence" or as divinely created materiality. Based on Kant's definition of being as positing, I argue, by contrast to Heidegger, that Kant understands being as the original productive relation between subject and object. This can also be expressed as the relation between formality and materiality, or between epistemic conditions and existence, that is productive of objects of experience. Being is not producedness but a relation of productivity, through which both subject and object are themselves productive. The subject is productive in its spontaneity, and nature, determined as dynamical interaction, is interpreted as productive. The subject, I will argue, does not understand nature as produced, but approaches it with a comportment towards its production as object of experience. Because of its own subjective productivity - spontaneity or "life" - the subject has a "productive comportment" towards nature. Ontology, I claim, concerns the realm of the productive relation of being, the realm of the relation between epistemic conditions and existence, and therefore the realm of possible experience. This marks Kant as divergent not only from what Heidegger calls "the ontology of the extant", but also from the concept-based ontology of the German rationalists. The general aims of the thesis are, first, to argue that being for Kant is the original relation between subject and object, and that ontology concerns this relation; second, to argue that ontology and being are understood in terms of production and productivity; and third, to argue that Heidegger is wrong to ascribe to Kant an understanding of being as "produced pennanent presence". I approach these aims by examining a number of Kant's texts in detail, focusing particularly on Kant's theses about existence and being in The One Possible Basis for a Demonstration of the Existence of God and the Critique of Pure Reason; on Kant's philosophy of nature and dynamical matter in the Transcendental Analytic and Metaphysical Foundations of Natural Science; on Kant's doctrine of experience and objectivity in the Transcendental Deductions; on ontological reflection and the productive comportment of "life" in the Critique of Judgment; and on Kant's final theory of matter, life and production in the Opus Postumum.

If something like Reformed Epistemology is correct, an agent is innocent in regarding certain ways of forming beliefs to be reliable until those ways have been proven guilty. An important species of argument purporting to show guilt (1) identifies the ways of forming beliefs at the core of our cognitive activity, (2) isolates the features of our core practices which account for their reliability, and (3) determines whether or not peripheral practices which ought to have those features enjoy at least (...) their functional equivalents. An example. Sense perception is at the heart of our cognitive activity; a feature of sense-perception which provides us with confidence in its reliability is that we can subject sense-perceptual beliefs to intersubjective criticism - others can check our beliefs. Beliefs about God formed on the basis of religious experience cannot be so checked and therefore lack positive epistemic status.An important response to such criticism consists of arguing that the difference between two ways of forming beliefs is just what we should expect given some relevant difference between the subject matters of those two ways of forming beliefs. This species of response employs what I call ‘the Ontological Principle,’ viz., that the nature or characteristics of an object constrain the way an agent ought to form beliefs about that object.In this paper, I attempt to provide a rationale for the Ontological Principle. I argue as follows. Any epistemic norm which requires of an agent that she enter into causal relations with an object which she cannot in the ‘nature’ of the case enter lacks epistemic merit - it violates the ought implies can dictum. Because the epistemic norms properly governing the cognitive activity of a given agent are constrained by the causal relations possible between an agent and an object of belief, and because the causal relations possible between an object of belief and an agent are determined in part by the characteristics of the object of belief, the epistemic norms properly governing the cognitive activity of a given agent are determined in part by the characteristics of the object of belief. That is, the Ontological Principle is true. (shrink)

The theory of living beings as machines of nature and the conception of composite substances endowed with conjoined souls, entelechies, or monads, as well as that of organic bodies, were solidified over the course of the transformations of Leibniz's thought that issued in the New System of Nature. On this basis, the monadological versions of a system of nature centered upon the integrated organization ad infinitum of living beings were gradually articulated. Leibniz aimed to spell out a science, or physiology (...) of vital processes, that would be, as much as possible, in agreement with the epistemological exigencies of the complex metaphysical model that he had elaborated. On the one hand, Leibniz offers a critical evaluation of the methodological options that divide the allegiances of the physicians and naturalists who are his contemporaries; what is more, he determines the profile of the analyses and explications that are to be promoted. For This double preoccupation translates into the scientific exchanges and correspondences that accompany the construction of the theory of organic bodies as constituents of machines of nature. The author focuses on the particular case of the propositions concerning the science of the living that stem from his reaction to the work of Georg Ernst Stahl. (shrink)
