Carl Hausman is a former editor of The Journal of Speculative Philosophy, a revival of one of the first American philosophy journals, where Peirce published some of his early work; and Hausman has devoted a good deal of his career to Peirce scholarship. He interprets Peirce’s thought “as a fallibilistic foundationalism that affirms a unique realism according to which what is real is a dynamic, evolving extramental condition.” The theme is an interesting one partly in view of the many recent (...) criticisms of foundationalism, some drawing on pragmatist sources. It promises to re-emphasize more conservative moments of the pragmatic conception of inquiry. Similarly, Hausman’s approach highlights the historical continuities between pragmatism and realism in American philosophy. Still, if Peircean realism implies evolutionary pressure due to “extra-mental” conditions, this suggests a question. Can we also expect a corresponding realism or autonomy of human lives, thought, and cultures—themselves evolving through their interactions? A positive answer here might help avoid the de-centering excesses of contemporary anti-foun-dationalists, implying social and institutional space for cross-fertilizations, innovations, and the rejection of social-institutional rigidities.

This paper has two objectives, neither previously attempted in the published literature—first, to outline J. M. Keynes's theory of knowledge in some detail, and, secondly, to justify the contention that his epistemology is a variety of rationalism, and not, as many have asserted, a form of empiricism. Keynes's attitude to empirical data is also analysed as well as his views on prediction and theory choice. 1This paper is partly based on ideas initially advanced in O'Donnell [1982], a revised and expanded (...) version of which is to be published as O'Donnell [1989]. I should like to thank an anonymous referee for helpful comment, and King's College, Cambridge for permission to quote from the Keynes Papers. (shrink)

During the period covered by this volume, Bertrand Russell first retired from and them resumed his philosophical career. In 1927 he published two philosophy books, The Analysis of Matter and An Outline of Philosophy. His next book in academic philosophy, An Inquiry into Meaning and Truth, was not published until 1940. Yet, Russell published many essays and popular books between 1927 and 1946, mostly to finance the running of Beacon Hill School, and his growing family. Those years also saw his (...) break-up with Dora Russell, his marriage to Patricia (Peter) Spence and a move of the family to the United States. Volume 10 brings together Russell's writings on ethics, politics, religion and academic philosophy. (shrink)

This paper concerns the recent debate on the nature and motivations of the epistemological project advanced in Rudolf Carnap's (18911970) Aufbau. Much of this debate has been initiated by Michael Friedman and Alan Richardson who argue (against the received view of the Aufbau as a foundationalist defense of empiricism) that Carnap's epistemological project is located in the tradition of neo-Kantian epistemology. On this revisionist reading of the Aufbau, Carnap's project is not motivated to address traditional empiricist problems regarding the justification (...) of knowledge, but rather to show how objective knowledge is possible. A central aspect of the Aufbau that is neglected in the revisionists' analysis is the role of epistemic justification in Carnap's project. The aim of the present study is to argue that although the general epistemology in the Aufbau can be cast as neo-Kantian, Carnap's method of construction theory (or rational reconstruction) is formulated precisely as an empiricist method for the justification of conceptual knowledge. Construction theory radically redefines `empirical justification' into a formal-conventional notion, and is part of Carnap's more general agenda of redefining epistemology as a purely formal discipline.

Alberto Casullo ("Necessity, Certainty, and the A Priori", Canadian Journal of Philosophy18, 1988) argues that arithmetical propositions could be discon¯rmed by appeal to an invented scenario, wherein our standard counting procedures indicate that 2 + 2 != 4. Our best response to such a scenario would be, Casullo suggests, to accept the results of the counting procedures, and give up standard arithmetic. While Casullo's scenario avoids arguments against previous "disconfirming" scenarios, it founders on the assumption, common to scenario and response, (...) that arithmetic might be independent of standard counting procedures. Here I show, by attention to tallying as the simplest form of counting, that this assumption is incoherent: given standard counting procedures, then (on pain of irrationality) arithmetical theory follows.

The first-person perspective is a challenge to naturalism. Naturalistic theories are relentlessly third-personal. The first-person perspective is, well, first-personal; it is the perspective from which one thinks of oneself as oneself* without the aid of any third-person name, description, demonstrative or other referential device. The exercise of the capacity to think of oneself in this first-personal way is the necessary condition of all our self-knowledge, indeed of all our self-consciousness. As important as the first-person perspective is, many philosophers have not (...) appreciated the force of the data from the first-person perspective, and suppose that the first-person perspective presents no particular problems for the naturalizing philosopher. For example, Ned Block commented, “It is of course [phenomenal] consciousness rather than...self-consciousness that has seemed such a scientific mystery.” (Block 1995, 230) And David Chalmers says that self-consciousness is one of those psychological states that “pose no deep metaphysical enigmas.” (Chalmers 1996, 24).

I want to raise a question for which I have no definitive answer. The question is how to understand first-personal phenomena—phenomena that that can be discerned only from a first-personal point of view. The question stems from reflection on two claims: First, the claim of scientific naturalism that all phenomena can be described and explained by science; and second, the claim of science that everything within its purview is intersubjectively accessible, and hence that all science is constructed exclusively form the (...) third-personal point of view. Using these two claims as premises, we can construct a simple valid argument, which I’ll label ‘The Master Argument:’. (shrink)

Since its original publication in 1979, The Possibility of Naturalism has been one of the most influential works in contemporary philosophy of science and social science. It is a cornerstone of the critical realist position, which is now widely seen as offering a viable alternative to move positivism and postmodernism. This revised edition includes a new foreword.

In that book I had two different, though not unrelated aims. The first chapter was concerned with traditional scepticisms about, e.g., the external world and induction. In common with Hume and Wittgenstein (and even Heidegger) I argued that the attempt to combat such doubts by rational argument was misguided: for we are dealing here with the presuppositions, the framework, of all human thought and enquiry. In the other chapters my target was different. It was that species of naturalism which tended (...) to discredit, or somehow to reduce to more scientifically acceptable, physicalistic terms, whole regions of ordinary human thought, language, and experience – in particular the regions of moral discourse, of the subjectively mental and of the intensional. Here my reaction, as well as my target, was different. I did not merely stress the inescapability of the natural or common human standpoint from which we normally take for granted all that is called in question by scientistic naturalism. I also allowed the latter its own validity from its own limited standpoint.2 Philosophical scepticism and scientistic naturalism represent two types of challenge to ‘central features of our ordinary thought and talk’.3 The overall aim of Scepticism and Naturalism is to respond to these challenges and thereby to vindicate what Strawson refers to elsewhere as ‘our natural metaphysics’.

The main characters of a philosophy meant as an activity which is not essentially different from science but deals with questions which go beyond the limits of present sciences are the following: 1) Philosophy is an investigation of the world. It is aimed at dealing with major issues and is justified only insofar as it deals with them. 2) Philosophy provides a global view, it is not limited to sectorial questions. So there cannot be a philosophy of mathematics alone, or (...) physics alone, or biology alone, and so on. 3)Being an investigation about the world, philosophy aims at knowledge. Therefore questions about knowledge are central in philosophy. 4)Philosophy is continuous with sciences. Its objectives are not essentially different from those of sciences. 5)Philosophy makes use of results of sciences. This is not accessory to it, it is essential for its progress. 6)The method of philosophy is essentially the same as that of sciences. 7) Philosophy seeks new knowledge. Seeking new knowledge is part of its deepest nature. 8) Philosophy seeks new discovery methods. Seeking new knowledge, it also seeks new methods to obtain it. 9) Philosophy tries unexplored routes and, by so doing, it may even give origin to new sciences. Its greatest value consists in this. 10) Philosophy makes use of the experience of philosophers of the past. For this may help us to understand where certain ideas lead, avoiding us to try routes which have already revealed fruitless. 11) A conclusive solution of philosophical problems is impossible. Their solutions are always provisional and are bound to be replaced sooner or later by others. Progress exists everywhere, even in philosophy. 12) Philosophy has no specific field of its own, nor specific techniques of its own. But because it moves on an unexplored ground, it is at the same time always exposed to the risk of failure but also capable of surprising developments, originating new sciences. (shrink)

Craig and Moreland present a rigorous analysis and critique of the major varieties of contemporary philosophical naturalism and advocate that it should be abandoned in light of the serious difficulties raised against it. The contributors draw on a wide range of topics including: epistemology, philosophy of science, value theory to basic analytic ontology, philosophy of mind and agency, and natural theology.

Many philosophers these days consider themselves naturalists, but it's doubtful any two of them intend the same position by the term. In Second Philosophy, Penelope Maddy describes and practices a particularly austere form of naturalism called "Second Philosophy". Without a definitive criterion for what counts as "science" and what doesn't, Second Philosophy can't be specified directly ("trust only the methods of science" for example), so Maddy proceeds instead by illustrating the behaviors of an idealized inquirer she calls the "Second Philosopher". (...) mhis Second Philosopher begins from perceptual common sense experimentation, theory formation and testing, working all the while to asses, correct and improve her methods as she goes. Second Philosophy is then the result of the Second Philosopher's investigations. Maddy delineates the Second Philosopher's approach by tracing her reactions to various familiar skeptical and transcendental views (Descartes, Kant, Carnap, late Putnam, van Fraassen), comparing her methods to those of other self-described naturalists (especially Quine), and examining a prominent contemporary debate (between disquotationalists and correspondence theorists in the theory of truth) to extract a properly second-philosophical line of thought. She then undertakes to practice Second Philosophy in her reflections on the ground of logical truth, the methodology, ontology and epistemology of mathematics, and the general prospects for metaphysics naturalized.

I argue that philosophy is like science in three interesting and non-obvious ways. First, the claims made by philosophy are synthetic, not analytic: philosophical claims, just like scientific claims, are not guaranteed by the structure of the concepts they involve. Second, philosophical knowledge is a posteriori, not a priori: the claims established by philosophers depend on the same kind of empirical support as scientific theories. And finally, the central questions of philosophy concern actuality rather than necessity: philosophy is primarily aimed (...) at understanding the actual world studied by science, not some further realm of metaphysical modality.

Like coastal cities in the third millennium, important areas of human discourse seem threatened by the rise of modern science. The problem isn't new, of course, or wholly unwelcome. The tide of naturalism has been rising since the seventeenth century, and the rise owes more to clarity than to pollution in the intellectual atmosphere. All the same, the regions under threat are some of the most central in human life--the four Ms, for example: Morality, Modality, Meaning and the Mental. Some (...) of the key issues in contemporary metaphysics concern the place and fate of such concepts in a naturalistic world view. (shrink)

Naturalism as spare as this is by no means platitudinous. However, most opposition to naturalism in contemporary philosophy is not opposition to naturalism in this basic sense, but to a more specific view of the relevance of science to philosophy. Similarly on the pro-naturalistic side. What most self-styled naturalists have in mind is the more specific view. As a result, I think, both sides of the contemporary debate pay insufficient attention to a different kind of philosophical naturalism — a different (...) view of the impact of science on philosophy. This different view is certainly not new — it has been with us at least since Hume — but nor is it prominent in many contemporary debates. (shrink)

Philosophical naturalism, according to which philosophy is continuous with the natural sciences, has dominated the Western academy for well over a century, but Michael Rea claims that it is without rational foundation. Rea argues compellingly to the surprising conclusion that naturalists are committed to rejecting realism about material objects, materialism, and perhaps realism about other minds.

This paper argues that a priori justification is, in principle, compatible with naturalism—if the a priori is understood in a way that is free of the inessential properties that, historically, have been associated with the concept. I argue that empirical indefeasibility is essential to the primary notion of the a priori; however, the indefeasibility requirement should be interpreted in such a way that we can be fallibilist about apriori-justified claims. This fallibilist notion of the a priori accords with the naturalist’s (...) commitment to scientific methodology in that it allows for apriori-justified claims to be sensitive to further conceptual developments and the expansion of evidence. The fallibilist apriorist allows that an a priori claim is revisable in only a purely epistemic sense. This modal claim is weaker than what is required for a revisability thesis to establish empiricism, so fallibilist apriorism represents a distinct position. (shrink)

I discuss two independent topics concerning Michael Devitt's Coming To Our Senses. My discussion of the first topic, naturalism, is brief. My discussion of the second topic, analyticity, is divided into four subsections, the first of which examines the definition of analyticity and is by far the longest.

Pragmatism is a philosophical movement developed near the turn of the century in the work of several prominent American philosophers, most notably, Charles Sanders Peirce, William James, and John Dewey. Although many contemporary analytic philosophers never studied American Philosophy in graduate school, analytic philosophy has been significantly shaped by philosophers strongly influenced by that tradition, most especially W.V. Quine, Donald Davidson, Hilary Putnam, and Richard Rorty. Like other philosophical movements, it developed in response to the then-dominant philosophical wisdom. What unified (...) pragmatism was its rejection of certain epistemological assumptions about the nature of truth, objectivity, and rationality. The rejection of these assumptions springs from the pragmatist's belief that practice is primary in philosophy. Meaningful inquiry originates in practice. Theorizing is valuable, for sure, but its value arises from practice, is informed by practice, and, its proper aim is to clarify, coordinate, and inform practice. Theorizing divorced from practice is useless. (shrink)

One of the jobs of philosophers of the special sciences is to connect the local concerns of particular disciplines with those of philosophy in general. The two-way complexities of this task are well-illustrated by the case of causation. On the one hand—from the outside, as it were— philosophers interested in general issues about causation are prone to turn to the special sciences for real-life examples of the use of causal notions. On the other hand, from the inside, the special disciplines (...) themselves throw up philosophical puzzles in which the notion of causation plays a role. When does correlation indicate causation, for example? Physics and economics both generate hard cases of this kind. (shrink)

[1] Imagine a well-trained mid-century American philosopher, caught in a rare traffic jam on the New Jersey Turnpike one warm summer afternoon in the early 1950s. He dozes in his warm car ... and awakes in the same spot on a chill Fall evening in the late 1990s, remembering nothing of the intervening years. It is as if he has been asleep at the wheel for almost half a century!

Pragmatists recommend that in approaching a problematic concept in philosophy, we should begin by examining the role it plays in the practical, cognitive and linguistic lives of the creatures who use it. This paper stems from an interest in pragmatic accounts, in this sense, of the various modal notions we encounter in science. I propose that pragmatists about these notions should avail themselves of the vocabulary of theoretical models. This vocabulary brings to the foreground the issues of function, use and (...) role in practice, on which pragmatists want to focus; while downplaying the naive representationalism that pragmatists see as an impediment to good philosophy. I show how this framework may be used to delineate a kind of pragmatic perspectivalism about probability, and argue that the same template offers a promising way to make sense of the link between causation and manipulability.

William James said that sometimes detailed philosophical argument is irrelevant. Once a current of thought is really under way, trying to oppose it with argument is like planting a stick in a river to try to alter its course: “round your obstacle flows the water and ‘gets there just the same’”. He thought pragmatism was such a river. There is a contemporary river that sometimes calls itself pragmatism, although other titles are probably better. At any rate it is the denial (...) of differences, the celebration of the seamless web of language, the soothing away of distinctions, whether of primary versus secondary, fact versus value, description versus expression, or of any other significant kind. What is left is a smooth, undifferentiated view of language, sometimes a nuanced kind of anthropomorphism or “internal” realism, sometimes the view that no view is possible: minimalism, deflationism, quietism. Wittgenstein is often admired as a high priest of the movement. Planting a stick in this water is probably futile, but having done it before I shall do it again, and—who knows?—enough sticks may make a dam, and the waters of error may subside.

Lecture I begins with a distinction between two themes in philosophical naturalism. The first theme takes science to be our best guide to what there is, the second takes it to be our best guide to the nature of our own thought and talk. Thus the first theme ('object naturalism') motivates a scientifically-constrained metaphysics, while the second ('subject naturalism') motivates a scientifically-constrained philosophy of language and philosophical psychology. The lecture discusses a sense in which these two themes may conflict: in (...) particular, a sense in which subject naturalism may undermine a presupposition of object naturalism. The presupposition in question is the assumption that belief, judgement and assertion are 'referential', or 'representational', in some theoretically robust sense. In showing that this assumption is itself open to naturalistic challenge, the lecture identifies a little-recognised vulnerability in popular forms of (object) naturalism. The remaining lectures aim to show, first, what conception(s) of representation might replace the assumption in question; and second, what the project of philosophical naturalism looks like, in the light of these changes. Lecture II begins with the so-called bifurcation thesis -- the view that speech acts into descriptive and non-descriptive categories. The lecture advocates a different bifurcation, between two notions of representation: an 'external', world-tracking notion, and an 'internal', inferentialist notion. I argue that traditional representationalism confuses these notions. Lecture III outlines a conception of the project of naturalistic philosophy, in the light of this new bifurcation thesis. The recognition that not all representations in the inferential sense need be representation in the world-tracking sense permits a new pluralism within the former class: a pluralism about the functions of representation (in the former sense) in the lives of natural creatures in a natural environment. I emphasise that this kind of pluralism is orthogonal to familiar programs for pluralism in the philosophy of science. It involves a new dimension of variability, that conventional representationalism simply hides from view. (shrink)

In everyday life we often act adequately, yet without deliberation. For instance, we immediately obtain and maintain an appropriate distance from others in an elevator. The notion of normativity implied here is a very basic one, namely distinguishing adequate from inadequate, correct from incorrect, or better from worse in the context of a particular situation. In the first part of this paper I investigate such ‘situated normativity’ by focusing on unreflective expert action. More particularly, I use Wittgenstein’s examples of craftsmen (...) (tailors and architects) absorbed in action to introduce situated normativity. Situated normativity can be understood as the normative aspect of embodied cognition in unreflective skillful action. I develop Wittgenstein’s insight that a peculiar type of affective behaviour, ‘directed discontent’, is essential for getting things right without reflection. Directed discontent is a reaction of appreciation in action and is introduced as a paradigmatic expression of situated normativity. In the second part I discuss Wittgenstein’s ideas on the normativity of what he calls ‘blind’ rule-following and the ‘bedrock’ of immediate action. What matters for understanding the normativity of (even ‘blind’) rule-following, is not that one has the capacity for linguistic articulation or reflection but that one is reliably participating in a communal custom. In the third part I further investigate the complex relationships between unreflective skillful action, perception, emotion, and normativity. Part of this entails an account of the link between normativity at the level of the expert’s socio-cultural practice and the individual’s situated and lived normativity. (shrink)

[After explaining why BonJour’s rationalist version of the abductivist reply to skepticism is more defensible than other versions of the view, I argue that the notion of probability he relies upon is deeply problematic, that he incorporates an implausible double-standard concerning a priori and a posteriori justification, and that his view is vulnerable to skepticism about the a priori. I suggest that some of these problems are due to idiosyncratic commitments BonJour makes and that abductivists would be better off without (...) them. I conclude with some suggestions about how to improve BonJour’s abductivist response to skepticism.]. (shrink)

I reconstruct and critique two arguments Laurence BonJour has recently offered against skepticism about the a priori. While the arguments may provide anti-skeptical, internalist foundationalists with reason to accept the a priori, I show that neither argument provides sufficient reason for believing the more general conclusion that there is no rational alternative to accepting the a priori.

In this paper, it is argued that metaphysics, conceived as an inquiry into the ultimate nature of mind-independent reality, is a rationally indispensable intellectual discipline, with the a priori science of formal ontology at its heart. It is maintained that formal ontology, properly understood, is not a mere exercise in conceptual analysis, because its primary objective is a normative one, being nothing less than the attempt to grasp adequately the essences of things, both actual and possible, with a view to (...) understanding as far as we can the fundamental structure of reality as a whole. Accordingly, it is urged, the deliverances of formal ontology have a modal and epistemic status akin to those of other a priori sciences, such as mathematics and logic, rather than constituting rivals to the claims of the empirical sciences, such as physics.

The Realm of Reason develops a new, general theory of what it is for a thinker to be entitled to form a given belief. The theory locates entitlement in the nexus of relations between truth, content, and understanding. Peacocke formulates three principles of rationalism that articulate this conception. The principles imply that all entitlement has a component that is justificationally independent of experience. The resulting position is thus a form of rationalism, generalized to all kinds of content. To show how (...) these principles are realized in specific domains, Peacocke applies the theory in detail to several classical problems of philosophy, including the nature of perceptual entitlement, induction, and the status of moral thought. These discussions involve an elaboration of the structure of entitlement in ways that have applications in many other areas of philosophy. He also relates the theory to classical and recent rationalist thought, and to current issues in the theory of meaning, reference and explanation. In the course of these discussions, he proposes a general theory of the a priori. The focus of the work lies in the intersection of epistemology, metaphysics, and the theory of meaning, and will be of interest both to students and researchers in these areas, and to anyone concerned with the idea of rationality.

Moderate rationalists maintain that our rational intuitions provide us with prima facie justification for believing various necessary propositions. Such a claim is often criticized on the grounds that our having reliable rational intuitions about domains in which the truths are necessary is inexplicable in some epistemically objectionable sense. In this paper, I defend moderate rationalism against such criticism. I argue that if the reliability of our rational intuitions is taken to be contingent, then there is no reason to think that (...) our reliability is inexplicable. I also suggest that our reliability is, in fact, necessary, and that such necessary reliability neither admits of, nor requires, any explanation of the envisaged sort.

In his most recent treatment of a priori knowledge, Philip Kitcher argues against what he takes to be the widespread view that our knowledge and warranted belief is 'tradition-independent'. Furthermore, he argues that defeasible conceptions of a priori warrant entail that it is not tradition-independent, a conclusion which he thinks is contrary to what most epistemologists hold. I argue that knowledge is not widely believed to be tradition-independent, and that, while warrant is widely believed to be tradition-independent, Kitcher's arguments show (...) neither that this widespread view is mistaken nor that it conflicts with defeasible a priori warrant. I conjecture that Kitcher may be misled by a lack of clarity regarding the analysandum designated by 'warrant'.
