Debates about nonconceptual content impact many philosophical disciplines, including philosophy of mind, epistemology, and philosophy of language. However, arguments made by many philosophers from within the pragmatist tradition, including Quine, Sellars, Davidson, Rorty, and Putnam, undercut the very role such content purportedly plays. I explore how specifically Sellarsian arguments against the Given and Rortian defenses of “epistemological behaviorism” undermine standard conceptions of nonconceptual content. Subsequently, I show that the standard objections to epistemological behaviorism inadequately attend to the essentially social and (...) practical nature of justification. (shrink)

The aim of this paper is to look at what a parallel deflationist program might be in the theory of knowledge and examine its prospect. In what follows I will simplify matters slightly by focussing on empirical knowledge rather than knowledge in general, though most of what I have to say ought to be applicable, mutatis mutandis, to knowledge in general. Moreover,note that it is not my aim to offer a full defense of a particular deflationist theory of knowledge, which (...) would go well beyond the scope of this paper, but only to defend the utility of taking the deflationist program as regards the theory of knowledge seriously by showing that there is a plausible deflationist position available that is worthy of further scrutiny.

Defenders of the Knowledge Argument contend that physicalism is false because knowing all the physical truths is not sufficient to know all the truths about the world. In particular, proponents of the Knowledge Argument claim that physicalism is false because the truths about the character of conscious experience are not knowable from the complete set of physical truths. This dissertation is a defense of the Knowledge Argument. Chapter one characterizes what physicalism is and provides support for the claim that if (...) knowing all the physical truths is not sufficient to know all the truths about the world, then physicalism is false. In chapter two, I defend the claim that knowing all the physical truths is not sufficient for knowing all the truths about the world. In addition to mounting a prima facie case for the knowledge intuition, I present and defend an epistemology grounded in direct acquaintance to provide a more substantive argument to accept it. Chapters three through five address the physicalist objections to the Knowledge Argument. The first set of objections advocates that knowing all the physical truths is, in fact, sufficient for knowing all the truths about the world. The next set of objections admits that there is some sense in which knowing all the physical truths is not sufficient for knowing all the truths about the world. However, these objections maintain that the kind of knowledge that is absent from the complete set of physical truths is know-how or knowledge by acquaintance, and not factual or propositional knowledge. The final set of objections maintain that the kind of propositional knowledge that is left out of the complete set of physical truths is compatible with physicalism. My response to these objections is part of advancing my prima facie case for the Knowledge Argument. The final chapter addresses a structural question that pertains to the Knowledge Argument. Some philosophers have maintained that the structure of the Knowledge Argument invites a kind of self-refutation of any systematic account of reality. The concern is that the Knowledge Argument proves too much, and that the dualist who uses the argument to refute physicalism risks the argument defeating his own position. I will argue that the Knowledge Argument does not refute dualism. (shrink)

Several recent contextualist theorists have proposed contextualizing the skeptic. Their claim is that oneshould view satisfactory answers to global doubts regarding such subjects as theexternal world, other minds, and induction as requirements for justification incertain philosophical contexts, but not in everyday and scientific contexts. Incontrast, the skeptic claims that a satisfactory answer to a global doubt in eachof these areas is a context-invariant requirement for justified belief. In this paper,I consider and reject the arguments Michael Williams develops in his bookUnnatural (...) Doubts that are intended to show that the skeptic's interpretationof the significance of global doubts is mistaken. In addition, I argue that Williams'general strategy in opposing the skeptic is extremely interesting and worth furtherinvestigation, even if his particular execution of it is unsuccessful. To this end, Iclarify the general strategy, distinguish it from a variety of others, and discuss itsprospects as an answer to the skeptic. (shrink)

In this paper, I argue that Humean theories of moral motivation appear preferable to Kantian approaches only if one assumes a broadly foundationalist conception of rational justification. Like foundationalist approaches to justification generally, Humean psychology aims to counter the regress-of-justification argument by positing a set of ultimate regress-stoppers-in this case, unmotivated desires. If the need for regress-stoppers of this type in the realm of practical deliberation is accepted, desires do indeed appear to be the most likely candidate. But if this (...) foundationalist strategy is rejected, there is no longer any reason to suppose that all motivation must be traceable to some extra-rational incentive. This clears the way for a rehabilitation of the Kantian claim that reasons for action can take the form of categorical imperatives. To illustrate this thesis, I show how a conception of practical rationality that incorporates a contextualist model of justification can be developed that treats social norms as reasons for action, without assigning any mediating role to agent desires. a theory of action of this type eliminates the gap between moral obligation and action, and so articulates the fundamental Kantian intuition that acting on the basis of moral principle-and with disregard for self-interest-is just one way of acting rationally.

I think that the epistemological theory presented by Plantinga would be more plausible if it were amended in a way that would be consistent with the no-foundations view suggested above. We have considered in detail his conception of basic beliefs in Section II above, and noted that his conception of basicality was obscure. For Plantinga, beliefs are basic only under certain conditions, and this is an obscure notion of basicality because unlike basic beliefs in a more traditional foundationalist theory, there (...) is no incorrigibility at the foundation, with no suitable substitute. Consequently, a foundationalist like Plantinga is faced with the same problem he thinks is inherent in coherentism; namely, how warrant for the noetic structure is guaranteed.In fact, it is unclear how Plantinga's version of foundationalism differs significantly from Williams' no-foundations view. If the noetic structure is potentially unlimited in the way that I have suggested, one could have a temporally local foundationalism which is consistent with Williams' no-foundations view, for all of Williams' arguments attack the notion of ultimate warrant for the noetic structure. And if, at a given time, a person takes certain beliefs in their noetic structure as basic contingent upon subsequent assessment of those beliefs, we have something very much like Plantinga's foundationalism. Such beliefs would be ‘basic’ in the sense of being non-inferentially credible, but this would not entail their functioning as grounds for the noetic structure as a whole, for the element lacking in this no-foundations view is the certain sort of experience which Plantinga thinks is necessary as a ground of the basic belief. But given the problems discussed above concerning criteria for basicality and the consequent problems concerning the identification of what sorts of experience function as a suitable ground, it is unclear in what way Plantinga's position is preferable.Plantinga's fundamental objection to a coherence view of justification was that there is no way of accounting for ultimate warrant for a noetic structure. But in reference to his own theory, Plantinga states that:The justification-conferring conditions mentioned above must be seen as conferring prima facie rather than ultima facie, or all-things-considered justification. This justification can be overridden. (“Reason”, 83)If, however, basic beliefs are merely prima facie justified and can be overridden, then there is no accounting for ultimate warrant in theological foundationalism either. Basic beliefs in a foundationalist position are supposed to serve the function of providing an end to the process of justification, but they do not serve this function in Plantinga's system. In defending the no-foundations view of justification, Williams recognizes that some beliefs are in fact accepted as non-inferentially credible or that some beliefs happen to be reliable (86, 94). If this is all that basic beliefs amount to, i.e. beliefs that are prima facie credible yet still defeasible, then theological foundationalism may as well scrap any hope of supplying adequate grounds for a noetic structure. Although more recent developments of foundationalism and coherentism, e.g. Laurence BonJour's The Structure of Empirical Knowledge (Cambridge: Harvard University Press, 1985) and William P. Alston's Epistemic Justification (Ithaca: Cornell University Press, 1989), contain refinements of the two theories which, ultimately, need to be considered in order to resolve the problems I raise here for theological foundationalism, I do not think these refinements significantly affect the arguments I present in this paper. In any case, I am considering these modifications in a work in progress. (shrink)

Many epistemologists agree with the intuition that “there is no exit from the circle of one’s beliefs”. I shall construe this vague intuition as the claim that justification supervenes on the totality of one’s beliefs: two agents with identical beliefs will be indistinguishable with respect to which of their beliefs are justified and to what degree. My central purpose in this paper is to undermine the supervenience thesis. To this end I shall consider the role(s) of the concept of justification.

This paper describes and assesses a number of dispositions which are instrumental in allowing us to take on the opinions of others unselfconsciously. It is argued that these dispositions are in fact reliable in the environments in which they tend to come into play. In addition, it is argued that agents are, by their own lights, justified in the beliefs they arrive at as a result of these processes. Finally, these processes are argued to provide a basis for rejecting the (...) claim that fixation of belief is radically holistic. (shrink)

Questions of objectivity involve many general philosophy of science issues; when directed toward the social sciences, even more complex issues surface about the status of the social sciences, e.g. can they be sciences as are the natural sciences? This paper does not take on this mass of issues directly, but instead argues for more restricted theses, in particular that questions about objectivity in the social sciences are often usefully seen as local empirical issues. I look at arguments around underdetermination, value (...) ladenness, the indeterminancy or nonquantitative nature of social science categories or attributes, and traditional ontological debates over materialism and idealism. I show that in all these cases some of the key issues about objectivity are specific empirical issues in the social sciences. (shrink)
