To assert is to utter a sentence under certain conventions, claims Michael Dummett. This view runs afoul of empirical evidence indicating the widespread assertoric use of non‐elliptical words and phrases. Dummett also advances two theses apparently related to his sentence conventionalism: that word meaning depends on sentence meaning, and that language is (in some sense) prior to thought. I argue that these latter two theses are independent of the empirically dubious Sentential Thesis. Plausibly, the wider Dummettian logico‐metaphysical programme is (...) not impugned by the existence of non‐sentential assertions. (shrink)

In this book, Jones methodically challenges both the claim that theological doctrines are the source of modern science and the idea that theology has the right to control the content of all scientific theories.

If I decide to disclose information about myself, this act can undermine other people’s ability to effectively conceal information about themselves. One case in point involves genetic information: if I share ‘my’ genetic information with others, I thereby also reveal genetic information about my biological relatives. Such dependencies are well-known in the privacy literature and are often referred to as ‘privacy dependencies’. Some take the existence of privacy dependencies to generate a moral duty to sometimes avoid sharing information about oneself. (...) If true, we argue, then it is sometimes justified for others to impose harm on the person sharing the information to prevent them from doing so. This is a highly revisionary implication. Hence, one must either endorse a highly revisionary view on what one may do to protect one’s privacy, or one must reject the view that privacy dependencies can be used to justify a moral duty that constrains choices about sharing information about oneself.

The Qualitative Thesis says that if you leave open P, then you are sure of if P, then Q just in case you are sure of the corresponding material conditional. We argue the Qualitative Thesis provides compelling reasons to accept a thesis that we call Conditional Locality, which says, roughly, the interpretation of an indicative conditional depends, in part, on the conditional’s local embedding environment. In the first part of the paper, we present an argument—due to Ben (...) Holguín—showing that, without Conditional Locality, the Qualitative Thesis is in tension with a margin for error principle on rational sureness. We show Conditional Locality reconciles the Qualitative Thesis with the margin for error principle. In the second part, we argue the full range of data supports what we call the Strong Qualitative Thesis. Without Conditional Locality, the Strong Qualitative Thesis has unacceptable consequences. But with Conditional Locality, it is tenable. (shrink)

It is widely considered a truism that the only evidence that can provide justification for one's belief that p is evidence in one's possession. At the same time, a good many epistemologists accept another claim seemingly in tension with this "truism," to the effect that evidence not in one's possession can defeat or undermine the justification for one's belief that p. Anyone who accepts both of these claims accepts what I will call the asymmetry thesis: while evidence in one's (...) possession can either enhance or detract from justification, evidence not in one's possession can only detract from it. The asymmetry thesis is not uncontroversial; but any epistemologist who endorses the doctrine of normative defeat will be under tremendous pressure to accept it. In this paper I try to motivate the asymmetry thesis in two steps: first, by appeal to a feature that assessments of justification share with evaluative assessments generally, according to which we can distinguish generic expectations in play from the explicit criteria for satisfying the relevant evaluative standard; and second, by arguing that when it comes to epistemic assessments, the generic expectations themselves derive from our roles as epistemic agents in communities in which we depend on one another for knowledge.

This dissertation explores various attempts to solve the Dependence Problem problem posed by the following question: How can necessary truths stand to God in a one-way relation of dependence, given that neither they nor God could have failed to exist?

Many writers in the field of business ethics seem to have accepted R. Edward Freeman’s argument to the effect that what he calls “the separation thesis,” or the idea that business and morality can be separated in certain ways, should be rejected. In this paper, I discuss how this argument should be understood more exactly, and what position “the separation thesis” refers to. I suggest that there are actually many interpretations (or versions) of the separation thesis going (...) around, ranging from semantic, empirical and reformative to some which are straightforwardly normative. While it is generally agreed that the separation thesis should be rejected, then, there is not as much agreement on what this thesis actually says. I suggest that whether or not we should<br>reject the separation thesis, however, ultimately must depend on how we understand it more exactly—on certain interpretations, the thesis comes out as more or less trivially false, but we should demand more evidence or argument to reject it on certain other interpretations. This result presents a challenge for all those writers who are committed to the rejection of the separation thesis. (shrink)

In earlier articles, the author developed what is known as the "Supersession Thesis," asserting that historic injustice may be overtaken by changes in circumstances so that a situation that was unjust when it was brought about may coincide with what justice requires at a later time. The Supersession Thesis was developed initially as a tool for considering historic injustice suffered by indigenous peoples in the European settlement of countries like Australia, Canada, New Zealand, and the United States. In (...) this paper, the author explores the application of the Supersession Thesis to issues about the Palestinian right of return and also to Israeli settlements in the Occupied Territories. The paper argues that, while it is not unthinkable that the Supersession Thesis might eventually legitimize the settlements and undermine the Palestinian right of return, there is no guarantee that this will happen. The application of the Supersession Thesis does not depend on the passage of time, but on changes in circumstances that a theory of justice makes relevant. Many of the circumstances that make the Supersession Thesis relevant to the post-colonial situations described do not apply in the Israeli situation. Nevertheless, it is worth considering the possibility of applying the Supersession Thesis in this case, because it enables us to assess the merits of the Thesis more sharply in relation to injustice that is taking place now, as opposed to injustice that took place in the nineteenth century.

Immanuel Kant’s well known and thoroughly discussed criticism of the cosmological argument, hereafter ‘CA’, is that it presupposes or depends upon the cogency of the ontological argument, hereafter ‘OA’. Call this criticism ‘the Dependency Thesis’. It is fair to say that the received view on the matter is that Kant failed to establish the Dependency Thesis.1 In what follows, I argue that the received view is mistaken. I begin by rehearsing the standard objection to what is (...) typically taken to be Kant’s primary argument for the Dependency Thesis. I defend Kant by presenting a different argument for his thesis. This argument is not vulnerable to the standard objection, and there is good reason to think that Kant had such an argument in mind. (shrink)

Which function is computed by a Turing machine will depend on how the symbols it manipulates are interpreted. Further, by invoking bizarre systems of notation it is easy to define Turing machines that compute textbook examples of uncomputable functions, such as the solution to the decision problem for first-order logic. Thus, the distinction between computable and uncomputable functions depends on the system of notation used. This raises the question: which systems of notation are the relevant ones for determining whether a (...) function is computable? These are the acceptable notations. I argue for a use criterion of acceptability: the acceptable notations for a domain of objects D\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {D}}$$\end{document} are the notations that we can use for the usual D\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {D}}$$\end{document}-activities. Acceptable notations for natural numbers are ones that we can count with. Acceptable notations for logical formulas are the ones that we can use in inference and logical analysis. And so on. This criterion makes computability a relative notion—whether a function is computable depends on which notations are acceptable, which is relative to our interests and abilities. I argue that this is not a problem, however, since there is independent reason for taking the extension of computable function to be relative to contingent facts. Similarly, the fact that the use criterion makes a mathematical distinction depend on practical concerns is also not a problem because it dovetails with similar phenomena in other areas of computability theory, namely the roles of notation in computation over real numbers and of Extended Church’s Thesis in complexity theory.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 36.3 (2003) 248-263 [Access article in PDF] The Incommensurability Thesis and the Status of Knowledge Maurice Charland The view that inquiry can be understood in terms of rhetorical theory can be traced to Thomas Kuhn's influential work, The Structure of Scientific Revolutions (1962). Kuhn is often cited by scholars concerned with the discursive strategies by which the natural and social or human sciences justify themselves (...) and their specific claims. Kuhn's legacy is well captured by Nelson, Megill, and McCloskey in the opening essay of The Rhetoric of the Human Sciences (1987) where they link him to Stephen Toulmin and Chaïm Perelman as instigators of the study of the Rhetoric of Inquiry. In their words, Kuhn's landmark classic "challenges philosophy to account for the actual operation of scientific communities—their professional devices of communication and socialization, their political structures, their reliance on aesthetics, and their rhetorical dependence on persuasion" (Nelson, Megill, and McCloskey 1987, 12). Despite this reaction, however, Kuhn's project was in many ways modest. He was not seeking to develop a sociology of science or a rhetoric of inquiry. He sought only to account for the form of modern science's history, which is not marked by linear progress, but by a succession of dominant frameworks, or what he termed paradigms.As I will argue in this essay, Kuhn's conception of paradigms is incompatible with rhetoric, except during scientific revolutions or under conditions of incommensurability. Incommensurability is a problematic category, however, for the opening it affords rhetoric ultimately undermines the very idea of paradigms. Consequently, locating rhetoric within normal science either undermines the very category distinctions that provide science with its specificity, or reduces rhetoric from a particular genre of discourse directed toward human agency to "rhetoricality," an aspect of all discourse. As we shall see, such blurring of genre distinctions is itself fundamentally [End Page 248] problematic, for science and rhetoric as discursive genres and practices are themselves incommensurable, even if not in Kuhn's terms. Rhetoric and revolution Kuhn observed that modern science is characterized by the bracketing of major disagreements regarding basic assumptions except during periods of "crisis." While pre-modern inquiry saw the contemporaneous co-existence of fundamentally incompatible frameworks, each competing for adherents, modern science normally excludes such divisions. Instead, modern science is characterized by a succession of frameworks. Only at periods of transition that are temporally bounded, for which Kuhn coined the term "scientific revolutions," does more than one framework have currency within a given sub-specialty (1962, 10-22).Kuhn accounts for this curious historical phenomenon by arguing that modern science is precisely constituted through an enforced bracketing of debates over first principles. The first principles, or paradigm, of any field are more than a set of epistemological or ontological assumptions. They are the set of rules constitutive of science as an activity. They orient scientists in their work, providing background assumptions, methodological principles, criteria of validity, a research agenda, and so on. The hegemony of a paradigm frees scientists from having to justify their work philosophically, socially, or politically. As Kuhn observes, normally science has the form of puzzle solving (35-42). He even likens it to a game, and like any game the participants need not concern themselves with the extrinsic validity of its rules or of the game itself. As Kuhn notes: Though many scientists talk easily and well about particular individual hypotheses that underlie a concrete piece of current research, they are little better than laymen at characterizing the established bases of their field, its legitimate problems and methods. If they have learned such abstractions at all, they show it mainly through their ability to do research. That ability can, however, be understood without recourse to hypothetical rules of the game. (47) Paradigms render modern science possible by producing practitioners and practices rather than by providing explicit knowledge of the principles such practices instantiate. In Foucault's language, we could say that practices are discursive formations (see Foucault 1972, 31-39). They are productive: [End Page 249] they give to knowledge... (shrink)

According to a widely held view, people's commitments to laws are dependent on the existence in their community of a conventional practice of complying with certain fundamental laws. This conventionalism has significantly hampered our attempts to explain the normative practice of law. Ronald Dworkin has argued against conventionalism by bringing up the phenomenon of persistent fundamental legal controversies, but neither Dworkin nor his legal positivist respondents have correctly understood the real significance of such controversies. This article argues that such controversies (...) pose a deep challenge to any conception of our legal practice as a genuinely normative, rule-mediated, practice. The article also argues that what is needed to deflect this challenge is a new understanding – different from the widely held conventionalist understanding – of how people's commitments to laws are predicated on their fellows’ like commitments.

In this journal, Luke Russell defends a sophisticated dispositional account of evil personhood according to which a person is evil just in case she is strongly and highly fixedly disposed to perform evil actions in conditions that favour her autonomy. While I am generally sympathetic with this account, I argue that Russell wrongly dismisses the mirror thesis—roughly, the thesis that evil people are the mirror images of the morally best sort of persons—which I have defended elsewhere. Russell’s rejection (...) of the mirror thesis depends upon an independently implausible account of moral sainthood, one that is implausible for reasons that Russell himself suggests in another context. Indeed, an account of moral sainthood that parallels Russell’s account of evil personhood is plausible for the same reasons that his account of evil personhood is, and that suggests that Russell himself is actually committed to the mirror thesis.

This is a response to an argument (by Michael McKinsey) purporting to show that anti-individualism is trivially true. I show that this argument rests upon a misconception of the basic claim of anti-individualism.

The paper reconsiders the Weber Thesis of a linkage between Calvinism and capitalism. It first restates this sociological Thesis in terms of the Calvinist doctrine of predestination as its theological core and premise in virtue of being treated as the crucial religious factor of the spirit of modern capitalism. Consequently, it proposes that the Weber Thesis’ validity and consistency depends on that doctrine, succeeding or failing as a sociological theory with the latter depending on whether or not (...) it is unique in theological terms, as well as economic-social consequences. For that purpose, it reexamines and compares the Calvinist doctrine of predestination with the pre-Calvinist versions and infers that it is basically identical to or compatible with these. It then draws the implications for the Weber Thesis in respect of the degree of its validity or consistence. It concludes that the Weber Thesis likely is fail as a sociological-economic theory with the Calvinist doctrine of predestination to the extent that the latter is its theological ground and revealed not to be unique and new theologically and probably in terms of its societal effects.

This paper begins with a discussion of the logical apparatus of Frege, where his use of Sinn suggests a modification of Leibniz's Principle of the Identity of Indiscernibles. Then, it turns to Strawson's basic particulars with its essentially Kantian orientation. This brings forward the logical ground upon which the Identity Thesis rests. Finally, following Frege with some modifications, the paper suggests that an ontological list where concepts can be treated as objective (materially dependent) subsistent entities would be necessary in (...) order to avoid errors of J. J. C. Smart and other analytic philosophers who hold the Identity Thesis. (shrink)

This article is a methodological discussion of formal approaches to the question of identity of proofs from a philosophical standpoint. First, an introduction to the question of identity of proofs itself is given, followed by a brief reconstruction of the so-called normalisation thesis, proposed by Dag Prawitz in 1971, in which some of its core mathematical and conceptual traits are presented. After that, a comparison between the normalisation thesis and the more well-known Church-Turing thesis on computability is (...) carried out in three main parts: the first dedicated to highlighting some of the analogies between them; the second, their most remarkable differences; and the third, to the possible relations of dependence between the two. Based on these considerations, some concluding remarks concerning the potential of the normalisation thesis and similar approaches to the question of identity of proofs are made in the last section.

In the Transcendental Deductions, Kant attempts to establish the necessary applicability of the categories to what is encountered in experience. As I see it, the argument is intended to deduce two distinct, but, in Kant’s eyes, interrelated, claims. The first is that it is a necessity that experience be of an objective world. Call this rough idea the objectivity thesis. The second thesis is that the categoriesapply only to mere appearances, that is, the world insofar as we structure (...) it. Call this the idealist thesis. P. F. Strawson attempted to split the two claims in order to save the objectivity thesis from what he saw as its unnecessary idealist trappings. My thesis is that the objectivity thesis depends upon the idealist thesis and cannot survive on its own. (shrink)

Moral responsibility theorists divide over whether facts about holding someone morally responsible are dependent on facts about being morally responsible, or whether the dependence relation runs in the other direction. A novel answer, proposed by Michael McKenna, is that neither side depends on the other. Instead, they are interdependent. Call this the ‘interdependence thesis’. A worry is that the interdependence thesis violates formal principles of metaphysical dependence in terms of ground. This paper analyses and defends the interdependence (...) class='Hi'>thesis, interacting with recent work in the metaphysics of grounding. I vindicate the interdependence thesis from the charge that it violates the formal principles of metaphysical grounding. I then pull from recent work in communication theory and apply it to McKenna's ‘conversational theory of moral responsibility’, in order to respond to two new objections. One upshot is that I advance the conversational theory of moral responsibility. (shrink)

Despite its proliferation in technology studies, the concept of “path dependence” has scarcely been applied to epistemology. In this essay, I investigate path dependence in the production of scientific knowledge, first, by considering Kuhn's scattered remarks that lend support to a path-dependence thesis (Section I) and second by developing and criticising Kuhn's embryonic account (Sections II and III). I examine a case from high-energy physics that brings the path-dependent nature of scientific knowledge to the fore and I pay attention (...) to two sources of path dependence—“theoretical” and “instrumental”. The latter source is particularly important in “big science”. I ask in Section IV whether path dependence in scientific knowledge can lead to circumstances like those in the technological field, in which a theory can come to dominate a scientific speciality even though it is inferior to alternatives. In Section V, I ask what implications my thesis has for science policy. (shrink)

It is often claimed that in normative political theory political imagination should remain unaffected by real-world contingencies: our idea of how the world “ought to be” should be independent from how the world “actually is”. According to the practice-dependent thesis, instead, “[t]he content, scope, and justification of a conception of justice depends on the structure and form of the practices that the conception is intended to govern”. This methodological approach conceives the relationship between theory and practice as an interplay: (...) normative theory applies to practice, but practices are also able to affect the content of normative theory. In this paper, I argue that the interplay between theory and practices that the practice-dependent method generates has not been fully understood. Though it may – at a superficial look – appear as a method compliant with the status quo, I will show that this method implies an idea of political theory as an activity of continuous critical engagement. Given an extended account of the method, political imagination has boundaries but these are not fixed nor easilydefinable: the real-world fact that constrains practice-dependent principles is the point and purpose of the practice they are meant to apply to, but this fact in itself is partly shaped and critically assessed by the theorist.

What is the relationship between perception and mental imagery? I aim to eliminate an answer that I call perceptualism about mental imagery. Strong perceptualism, defended by Bence Nanay, predictive processing theorists, and several others, claims that imagery is a kind of perceptual state. Weak perceptualism, defended by M. G. F. Martin and Matthew Soteriou, claims that mental imagery is a representation of a perceptual state, a view sometimes called The Dependency Thesis. Strong perceptualism is to be rejected since (...) it misclassifies imagery disorders and abnormalities as perceptual disorders and abnormalities. Weak Perceptualism is to be rejected since it gets wrong the aim and accuracy conditions of a whole class of mental imagery–projected mental imagery–and relies on an impoverished concept of perceptual states, ignoring certain of their structural features. Whatever the relationship between perception and imagery, the perceptualist has it wrong. (shrink)

This paper reconsiders the challenge presented to scientific realism by the semantic incommensurability thesis. A twofold distinction is drawn between methodological and semantic incommensurability, and between semantic incommensurability due to variation of sense and due to discontinuity of reference. Only the latter presents a challenge to scientific realism. The realist may dispose of this challenge on the basis of a modified causal theory of reference, as argued in the author’s 1994 book, The incommensurability thesis. This referential response has (...) been the subject of a charge of meta-incommensurability by Hoyningen-Huene et al., who argue that the realist’s referential response begs the question against anti-realist advocates of incommensurability. In reply, it is noted that a tu quoque rejoinder is available to the realist. It is also argued that the dialectical situation favours the scientific realist, since the anti-realist defence of incommensurability depends on an incoherent distinction between phenomenal world and world-in-itself. In light of such incoherence, and a strong commonsense presumption in favour of realism, the referential response to semantic incommensurability may be justifiably based on realism. (shrink)

In this chapter, I sketch a conceptual framework which takes it as a starting point that conscious and unconscious cognition are rooted in the same set of interacting learning mechanisms and representational systems. On this view, the extent to which a representation is conscious depends in a graded manner on properties such as its stability in time or its strength. Crucially, these properties are accrued as a result of learning, which is in turn viewed as a mandatory process that always (...) accompanies information processing. From this perspective, consciousness is best characterized as involving (1) a graded continuum defined over “quality of representation”, such that availability to consciousness and to cognitive control correlates with quality , and (2) the implication of systems of metarepresentations. A first implication of these ideas is that the main function of consciousness is to make flexible, adaptive control over behavior possible. A second, much more speculative implication, is that we learn to be conscious. This I call the “radical plasticity thesis” — the hypothesis that consciousness emerges in systems capable not only of learning about their environment, but also about their own internal representations of it.

The developers of ecological ethics claim that the rationale of anthropocentrism is false. Its main message is that natural complexes and resources exist to be useful to the human being who sees them only from the perspective of using them and does not take into account their intrinsic value. Kant’s anthropocentric teaching argues that the instrumental attitude to nature has its limits. These limits are hard to determine because the anthropocentrists claim that the human being is above nature. Indeed, the (...) “human exclusiveness thesis” (J.- M. Schaeffer) assumes that its advocates underestimate nature’s impact on humans and their connection to other living beings. Constructing a dialogue between Kant and Schaeffer helps to solve two problems. First, to determine whether Kant’s ethical and teleological concept is immune to Schaeffer’s critique. Second, to clarify the German philosopher’s contribution to environmental ethics. I come to the conclusion that it is premature to claim that consciousness and free will exist only in the framework of their being conditioned by nature. I also demonstrate that in his teleological teaching Kant sees the mechanism of nature as the dependence of living things on forces that act in an unpremeditated manner. Recognition of these forces sets limits to humans’ instrumental attitude to nature and paves the way for them to become moral subjects. Thus, Kant’s teaching combines “the human exclusiveness thesis” and the intuitions of the representatives of deep ecology and the opponents of anthropocentrism as such. (shrink)

The general problem as to the intrinsic nature of the states of consciousness is what these are in themselves, what intrinsic properties they have as the occurrences that they are. William James later holds them to be “pure experiences”; they are intrinsically neutral, not mental or physical, though they are commonly taken as such. This is part of a major ontological revision of James’s well-known earlier approach, since he now holds everything extant is pure experience. In “Does Consciousness Exist?” — (...) on which my article focuses — James applies his new approach to the topic of consciousness, and he proposes that this amounts to the function of knowing, which pure experiences instantiate with respect to other pure experiences, erroneously taking the latter to be as they are not: subjective or objective depending upon a context of associated experiences. Their intrinsic properties are held not to be mental or physical or any combination of such; and James seems to want to conceive of pure experiences as lacking in every property, except as they are interpreted at the moment, or in retrospect, in terms of a group of experiences to which they belong. James’s revised account of the states of consciousness is closely considered in the present article, his new account is contrasted with the one which he advocated in The Principles, and objections are here developed to the thesis that the states of consciousness are actually pure experiences.

The thesis that a temporal asymmetry of counterfactual dependence characterizes our world plays a central role in Lewis’s philosophy, as. among other things, it underpins one of Lewis most renowned theses—that causation can be analyzed in terms of counterfactual dependence. To maintain that a temporal asymmetry of counterfactual dependence characterizes our world, Lewis committed himself to two other theses. The first is that the closest possible worlds at which the antecedent of a counterfactual conditional is true is one in (...) which a small miracle occurs—i.e. one whose laws differ from the actual laws in a small spatiotemporal region. The second is that our world is characterized by a temporal asymmetry of miracles. In this paper, I will argue, first, that the latter thesis is either false or incompatible with the picture of the relations among temporal asymmetries endorsed by Lewis and, second, that former thesis conflicts with some of the intuitions which seem to guide us when engaging in counterfactual reasoning. If there is any fact of the matter as to which possible worlds in which the antecedent of a counterfactual conditional is true are closest to the actual world, these are not worlds at which a small miracle occurs.

The claim that truth is mind dependent has some initial plausibility only if truth bearers are taken to be mind dependent entities such as beliefs or statements. Even on that assumption, however, the claim is not uncontroversial. If it is spelled out as the thesis that “in a world devoid of mind nothing would be true”, then everything depends on how the phrase ‘true in world w’ is interpreted. If ‘A is true in w’ is interpreted as ‘A is (...) true of w’ (i.e. ‘w satisfies A’s truth conditions’, the claim need not be true. If on the other hand it is interpreted as ‘A is true of w and exists in w’ then the claim is trivially true, though devoid of any antirealistic efficacy. Philosophers like Heidegger and Rorty, who hold that truth is mind dependent but reality is not, must regard such principles as “A if and only if it is true that A” as only contingently true, which may be a good reason to reject the mind dependence of truth anyway.

The variety-of-evidence thesis has been criticized by Bovens and Hartmann. This article points to two limitations of their Bayesian model: the conceptualization of unreliable evidential sources as randomizing and the restriction to comparing full independence to full dependence. It is shown that the variety-of-evidence thesis is rehabilitated when unreliable sources are reconceptualized as systematically biased. However, it turns out that allowing for degrees of independence leads to a qualification of the variety-of-evidence thesis: as Bovens and Hartmann claimed, (...) more independence does not always imply stronger confirmation.

In a previous article, I argued against the widespread reluctance of philosophers to treat skeptical challenges to oura prioriknowledge of necessary truths with the same seriousness as skeptical challenges to oura posterioriknowledge of contingent truths. Hamid Vahid has recently offered several reasons for thinking the unequal treatment of these two kinds of skepticism is justified, one of which isa prioriskepticism’s seeming dependence upon the widely scornedkkthesis. In the present article, I defenda prioriskepticism against Vahid’s criticisms.

Medium specificity is a theory, or rather a cluster of arguments, in aesthetics that rests on the idea that media are the physical material that makes up artworks, and that this material contains specific and unique features capable of 1) differentiating media from one another, and 2) determining the aesthetic potential and goals of each medium. As such, medium specificity is essential for aestheticians interested in matters of aesthetic ontology and value. However, as Noël Carroll has vehemently and convincingly argued, (...) the theory of medium specificity is inherently flawed and its many applications in art history ill-motivated. Famously, he concluded that we should ‘forget the medium’ entirely. In this thesis, I reject his conclusion and argue that reconstructing a theory of medium specificity, while taking Carroll’s objections into account, is possible. To do so, I offer a reconceptualization of the main theoretical components of medium specificity and ground this new theory in empirical research. I first redefine the medium not as the physical material that makes up artworks but as sets of practices – not the material itself but how one uses the material. I then show that what makes media specific and unique is not certain physical features, but the human responses, which can be empirically investigated, to the combination of practices that constitute media. This relation is one of response-dependence, albeit of a novel kind, which I develop by appealing to social metaphysics. The resulting theory is more complex but also much more flexible and fine-grained than the original and provides insight into a variety of current aesthetic theories. (shrink)

Does the cosmological argument (CA) depend on the ontological (OA)? That depends. If the OA is an argument “from mere concepts,” then no; if the OA is an argument from possibility, then yes. That is my main thesis. Along the way, I explore a number of subsidiary themes, among them, the nature of proof in metaphysics, and what Kant calls the “mystery of absolute necessity.”.

Huw Price has argued that on an interventionist account of cause the distinction is perspectival, and the claim prompted some interesting responses from interventionists and in particular an exchange with Woodward that raises questions about what it means to say that one or another structure is perspectival. I’ll introduce his reasons for claiming that the distinction between cause and effect on an interventionist account is perspectival. Then I’ll introduce a distinction between different ways in which a class of concepts can (...) be said to depend on facts about their users. Three importantly different forms of dependence will emerge from the discussion: Pragmatic dependence on us: truth conditions for x-beliefs can be given by a function f \ of more fundamental physical structures making no explicit reference to human agents. But there are any other number of functions ) ontologically on a par with x and what explains the distinguished role f plays in our practical and epistemic lives are facts about us. Implicit relativization: truth conditions for x-beliefs are relative to agent or context; the context supplies the value of a hidden parameter that determines the truth of x-beliefs. Indexicals: like implicit relativization except that the surface syntax contains a term whose semantic value is context-dependent. I suggest that Price’s insights are best understood in the first way. This will draw a crucial disanalogy with his central examples of perspectival concepts, but it will refine the thesis in a way that is more faithful to what his arguments show. The refined thesis will also support generalization to other concepts, and clarify the foundations of the quite distinctive research program that Price has been developing for a number of years.

The Variety of Evidence Thesis (VET) says that (ceteris paribus) the more diverse (or varied) of two bodies of evidence is the more confirmatory of a hypothesis H. Two recent types of Bayesian explication of VET account for the intuitive force of VET by defining variety as some function of the probabilities of the propositions which collectively constitute a body of evidence. I show that these two accounts of VET are not tracking a meaningful property of bodies of evidence, (...) but rather are tracking artifacts of how those bodies of evidence are described. According to each account, whether a body of evidence is more varied than another depends on how the bodies are split into parts. Furthermore, for each type of account there exists a way to redescribe the total evidence such that any two totalities are equally varied. ‡I would like to thank Elliott Sober for comments on multiple drafts of this paper, and Malcolm Forster, John Koolage, and Joel Velasco for comments on a verbal delivery. †To contact the author, please write to: Department of Philosophy, University of Wisconsin-Madison, 5185 Helen C.

Joseph Raz's famous theory of authority is grounded in three claims about the nature and justification of authority. According to the Preemption Thesis, authoritative directives purport to replace the subject's judgments about what she should do. According to the Dependence Thesis, authoritative directives should be based on reasons that actually apply to the subjects of the directive. According to the Normal Justification Thesis (NJT), authority is justified to the extent that subjects are more likely to comply with (...) right reason by following the authority's directives than by following their own judgments about what right reason requires.1In this article, I consider a number of ways in which NJT might be construed as a justification for authority. First, I evaluate NJT construed as a principle that would provide a practical justification for an individual to accept or recognize a particular person or persons as a preemptive authority. Second, I evaluate NJT construed as a principle that describes the conditions under which a state or legal system is morally legitimate. I argue that NJT is true under none of these interpretations.2. (shrink)

: The work of Boris Hessen and Henryk Grossman on the emergence of early modern science is an attempt at a historical sociology of science and a historical epistemology of scientific knowledge. One of their theses is elaborated here, namely that early modern mechanics developed in the study of contemporary technology. In particular I discuss the thesis that the replacement of the Aristotelian concept of motion by the modern general and mathematical concept developed in the study of transmission machines. (...) In addition to a discussion of the thesis and its implications, I also present a case study to substantiate the thesis. I show that Benedetti's famous refutation of Aristotle and his introduction of a new concept of motion depended on empirical knowledge of the newly invented treadle mechanism. I argue that although the historiography of science since the 1930s has explored many of the individual issues first raised by the Marxist historians of science, this perspective remains unique in that it establishes direct and informative connections between the grand narrative of the transition from agrarian-feudal society to industrial production in early capitalism and the development of science and technology down to specific cognitive issues such as shared assumptions concerning the natural order.

This paper considers the relevance of the Duhem-Quine thesis in economics. In the introductory discussion which follows, the meaning of the thesis and a brief history of its development are detailed. The purpose of the paper is to discuss the effects of the thesis in four specific and diverse theories in economics, and to illustrate the dependence of testing the theories on a set of auxiliary hypotheses. A general taxonomy of auxiliary hypotheses is provided to demonstrate the (...) confounding of auxiliary hypotheses with the testing of economic theory. (shrink)

In this dissertation, I explore the reach of the Evolutionary Contingency Thesis—a view that emphasizes the role of dependency relations and chance in evolution. Contingency produces diverse biological entities, processes, and mechanisms. I analyze the implications of evolution’s contingency in three areas. First, I address the problem of evolutionary individuality, which concerns the nature of entities that selection acts on. If we accept Lewontin’s 1970 view that individuals are selected, then what exactly are these individuals? I argue that (...) evolutionary contingency and its diversity of outcomes causes a plurality of individuality types. These types of individuals emerge, evolve, and disappear through evolution. Second, I defend a disunified model of major transitions in evolution. Major transitions mark pivotal turning points in life’s history, such as the transition from unicellularity to multicellularity. Philosophers and biologists aim to unify evolution’s transitions by establishing a property all major events share. I argue that evolutionary contingency’s emphasis on diversity supports a disunified model of transitions. That is, we should expect numerous kinds of major transitions given the diverse sets of outcomes caused by evolutionary contingency. Finally, I extend the contingency analysis to a topic in philosophy of medicine: The nature of cancer. It is common to view cancer as a by-product of our evolution as multicelled creatures. However, Lean and Plutynski argue that cancer is also a direct product of evolution by selection. In both cases, cancer is characterized in terms of how it functions as an object of selection. I argue that the diversity among cancers suggests philosophers should shift their focus to cancers’ structural differences rather than only their functional similarities. (shrink)

According to a widespread view in metaphysics and philosophy of science, all explanations involve relations of ontic dependence between the items appearing in the explanandum and the items appearing in the explanans. I argue that a family of mathematical cases, which I call “viewing-as explanations”, are incompatible with the Dependence Thesis. These cases, I claim, feature genuine explanations that aren’t supported by ontic dependence relations. Hence the thesis isn’t true in general. The first part of the paper defends (...) this claim and discusses its significance. The second part of the paper considers whether viewing-as explanations occur in the empirical sciences, focusing on the case of so-called fictional models. It’s sometimes suggested that fictional models can be explanatory even though they fail to represent actual worldly dependence relations. Whether or not such models explain, I suggest, depends on whether we think scientific explanations necessarily give information relevant to intervention and control. Finally, I argue that counterfactual approaches to explanation also have trouble accommodating viewing-as cases. (shrink)

Othering is the construction and identification of the self or in-group and the other or out-group in mutual, unequal opposition by attributing relative inferiority and/or radical alienness to the other/out-group. Othering can be “crude” or “sophisticated”, the defining difference being that in the latter case othering depends on the interpretation of the other/out-group in terms that are applicable only to the self/in-group but that are unconsciously assumed to be universal. The Mass Noun Thesis, the idea that all nouns in (...) certain languages are grammatically and folk-ontologically similar to mass nouns in English, is an example of such sophisticated othering. According to this Thesis, (a) count nouns refer to discrete objects and mass nouns to stuffs; (b) the other’s language has only mass nouns and thus no count nouns; and therefore, (c) the other’s folk-ontology is an ontology of mass stuffs only. There is much evidence, however, that folk-ontology is independent from language. This paper argues that the Mass Noun Thesis is a case of sophisticated othering rooted in a conflation of grammatical and ontological conceptions of mass and count nouns that is applicable to the language of the interpreter/self but not to the languages of the relevant others, and that othering in this case is driven by a need to create some radically alien other to support a scientific or philosophical theory.

The principle of clinical equipoise requires that, aside from certain exceptional cases, second generation treatments ought to be tested against standard therapy. In violation of this principle, placebo-controlled trials (PCTs) continue to be used extensively in the development and licensure of second-generation treatments. This practice is typically justified by appeal to methodological arguments that purport to demonstrate that active-controlled trials (ACTs) are methodologically flawed. Foremost among these arguments is the so called assay sensitivity argument. In this paper, I take a (...) closer look at this argument. Following Duhem, I argue that all trials, placebo-controlled or not, rely on external information for their meaningful interpretation. Pending non-circular empirical evidence that we can trust the findings of PCTs to a greater degree than the findings of ACTs, I conclude that the assay sensitivity argument fails to demonstrate that placebo-controlled trials are preferable, methodologically or otherwise, to active-controlled trials. Contrary to the intentions of its authors, the fundamental lesson taught by the assay sensitivity argument is Duhemian: the validity of all clinical trials depends on external information. (shrink)

This essay argues that the concept of dependence now invoked in noramtive discussions of the welfare state is both incoherent and biased as a result of its conflation of four distinctly different notions of dependence, ranging from the purely causal to that associated with lower class identities.

The weak natural law thesis asserts that any instance of law is either a rational standard for conduct or defective. At first glance, the thesis seems compatible with the proposition that the validity of a law within a legal system depends upon its sources rather than its merits. Mark C. Murphy has nonetheless argued that the weak natural law thesis can challenge this core commitment of legal positivism via an appeal to law’s function and defectiveness conditions. My (...) contention in the current paper is that in order to make good on the challenge, the defender of the weak natural law thesis should appeal explicitly to the common good, understood as the principal normative reason in the political domain. In section I I outline the main implications of the weak natural law thesis and clarify a common misunderstanding regarding its explanatory role. Section II then argues for the indispensability of the common good to the natural law jurisprudential thesis on the grounds that it has an essential role to play in a natural law account of law’s defectiveness conditions and the presumptive moral obligatoriness of legal norms. Finally, in section III I examine the compatibility of a strengthened version of the weak natural law thesis with legal positivism in light of the centrality of the common good to the natural law jurisprudential position.

Resumen: Derek Parfit en Personas, racionalidad y tiempo sostiene que si bien es posible concebir experiencias sin referir a personas, las experiencias dependen para su existencia de las personas, y a su vez, las experiencias dependerían para su identidad de cierta otra entidad no idéntica con la entidad persona. Tal tesis, que deviene de determinado experimentos mentales de Parfit, específicamente del argumento Mi División y el Argumento del Hospital, se revisará desde ciertas nociones metafísicas de E. J. Lowe, en específico, (...) desde la tesis que supone que dependencia de identidad implica dependencia existencial, de forma que si x depende para su identidad de y, x dependería, de igual forma, para su existencia de y. Tal supuesto permitirá desarrollar ciertas problemáticas para lo que Parfit sostiene en su esquema sobre la dependencia de las experiencias.: Derek Parfit in People, rationality and time argues that although it is possible to conceive experiences without referring to people, experiences depend on people for their existence, and in turn, experiences would depend on certain other entity not identical to the person entity for their identity. This thesis, which comes from certain mental experiments of Parfit, specifically from My Division argument and the Hospital Argument, will be reviewed from certain metaphysical notions of E. J. Lowe, specifically, from the thesis that assumes that identity dependence implies existential dependence, so that if x depends on the identity of y, x would depend, in the same way, on the existence of y. This assumption will bring to developing certain problems concerning what Parfit holds in his scheme on the dependence of experiences. (shrink)

The practice-dependent approach to justice has received a lot of attention in post-millennium political philosophy. It has been developed in different directions and its normative implications have been criticized, but little attention has been directed to the very distinction between practice-dependence and practice-independence and the question of what theoretically differentiates a practice-dependent account from mainstream practice-independent accounts. The core premises of the practice-dependent approach, proponents argue, are meta-normative and methodological. A key feature is the presumption that a concept of justice (...) is dependent on the function or aim of the social practices to which it is supposed to be applied. Closely related to this meta-normative thesis is an interpretive methodology for deriving principles of justice from facts about existing practices, in particular regarding their point and purpose. These two premises, practice-dependent theorists claim, differentiate their account since they are not accepted by practice-independent accounts and they justify different principles of justice than practice-independent accounts. Our aim in this article is to refute both and, demonstrating that practice-independent accounts may indeed accept the meta-normative and methodological premises of the practice-dependent accounts, and that we are given no theoretical reason to think that practice-dependent accounts justify other principles of justice for a practice than do practice-independent accounts. In other words, practice-dependent theorists have not substantiated their claim that practice-dependence is theoretically differentiated from mainstream accounts. When practice-dependent proponents argue for other principles of justice than mainstream theorists, it will be for the usual reason in normative theory: their first-order normative arguments differ.

According to the Extended Mind thesis, the mind extends beyond the skull or the skin: mental processes can constitutively include external devices, like a computer or a notebook. The Extended Mind thesis has drawn both support and criticism. However, most discussions—including those by its original defenders, Andy Clark and David Chalmers—fail to distinguish between two very different interpretations of this thesis. The first version claims that the physical basis of mental features can be located spatially outside the (...) body. Once we accept that the mind depends on physical events to some extent, this thesis, though not obvious, is compatible with a large variety of views on the mind. The second version applies to standing states only, and has to do with how we conceive the nature of such states. This second version is much more interesting, because it points to a potential tension in our conception of minds or selves. However, without properly distinguishing between the two theses, the significance of the second is obscured by the comparative triviality of the first. (shrink)

Alvin Plantinga’s externalist religious epistemology, which incorporates a proper function account of warrant, forms the basis for his standard and extended Aquinas/Calvin models. Respectively, these models show how it could be that Theistic Belief and Christian Belief could be warranted for believers in a properly basic manner. Christianity and Islam share fundamental theses that underlie the plausibility of Plantinga’s models: the Dependency Thesis, the Design Thesis, and the Immediacy Thesis. Accordingly, an Islamic worldview can endorse the (...) truth of the standard A/C model but recommend a uniquely Islamic extension. Thus, there are multiple viable extensions of the standard A/C model. That there are Multiple Viable Extensions of the standard A/C model grounds the Multiple Viable Extensions Objection (MVE): given the truth of the standard A/C model, it is more likely than not that a given extension of it is probably incorrect, thus those who accept some extension of the standard A/C model have a reason to think that model they affirm is incorrect. After considering the plausibility of second-order knowledge states and responding to objections, I conclude that because a uniquely Islamic extension of the standard A/C model advocates a limited second-order awareness condition on knowledge, it is plausible to think that an Islamic model of warrant (and its corresponding Islamic extension) suggests ways in which a satisfactory response to the MVE objection might be formulated.

This paper defends the naïve thesis that the method of experiment has per se an epistemic superiority over the method of computer simulation, a view that has been rejected by some philosophers writing about simulation, and whose grounds have been hard to pin down by its defenders. I further argue that this superiority does not come from the experiment’s object being materially similar to the target in the world that the investigator is trying to learn about, as both sides (...) of dispute over the epistemic superiority thesis have assumed. The superiority depends on features of the question and on a property of natural kinds that has been mistaken for material similarity. Seeing this requires holding other things equal in the comparison of the two methods, thereby exposing that, under the conditions that will be specified, the simulation is necessarily epistemically one step behind the corresponding experiment. Practical constraints like feasibility and morality mean that scientists do not often face an other-things- equal comparison when they choose between experiment and simulation. Nevertheless, I argue, awareness of this superiority and of the general distinction between experiment and simulation is important for maintaining motivation to seek answers to new questions. (shrink)
