Justified Judging

Traditional approaches to epistemology have sought, unsuccessfully, to define knowledge in terms of justification. I follow Timothy Williamson in arguing that this is misconceived and that we should take knowledge as our fundamental epistemological notion. We can then characterise justification as a certain sort of approximation to knowledge. A judgement is justified if and only if the reason (if there is one) for a failure to know is to be found outside the subject's mental states; that is, justified judging is possible knowing (where one world accessible from another if and only if they are identical with regard to a subject's antecedent mental states and judgement forming processes). This view is explained and defended.     

Skepticism about Skepticism about Moral Responsibility

This article rejects Gideon Rosen's skeptical argument that attributions of blameworthiness are never epistemically justified. Granting Rosen's controversial claim that an act is blameworthy only if it is either akratic or the causal upshot of some akratic act, I show that we can and should resist his skeptical conclusion. I show, first, that Rosen's argument is, at best, hostage to a much more global skepticism about attributions of praiseworthiness, doxastic justification, and other phenomena which essentially involve causal‐historical facts about mental states. I then show how, equipped with proper background knowledge, we can justifiedly attribute blameworthiness.     

The problem of evil: skeptical theism leads to moral paralysis

Natural disasters would seem to constitute evidence against the existence of God, for, on the face of things, it is mysterious why a completely good and all-powerful God would allow the sort of suffering we see from earthquakes, diseases, and the like. The skeptical theist replies that we should not expect to be able to understand God’s ways, and thus we should not regard it as surprising or mysterious that God would allow natural evil. I argue that skeptical theism leads to moral paralysis: accepting skeptical theism would undermine our ability to make any moral judgments whatsoever. Second, and more briefly, I argue that skeptical theism would undercut our ability to accept any form of the argument from design, including recent approaches based on fine-tuning.     

Shelter for the Cognitively Homeless

One of the main strands of the Cartesian tradition is the view that the mental realm is cognitively accessible to us in a special way: whenever one is in a mental state of a certain sort, one can know it just by considering the matter. In that sense, the mental realm is thought to be a cognitive home for us, and the mental states it comprises are luminous. Recently, however, Timothy Williamson has argued that we are cognitively homeless: no mental state is in fact luminous. But his argument depends on an excessively strong account of luminosity. I formulate a weaker conception of luminosity that is unaffected by Williamson’s argument and yet is substantial enough to satisfy those who wish to retain this part of the Cartesian tradition.     

Which Mental States Are Rationally Evaluable,And Why?

What makes certain mental states subject to evaluation with respect to norms of rationality and justification, and others arational? In this paper, I develop and defend an account that explains why belief is governed by, and so appropriately subject to, evaluation with respect to norms of rationality and justification, one that does justice to the complexity of our evaluative practice in this domain. Then, I sketch out a way of extending the account to explain when and why other kinds of mental states are rationally evaluable. I argue that the cognitive or psychological mechanisms that give rise to and sustain our mental states help to render our mental states appropriate targets for evaluation with respect to norms of rationality and justification when the operation of these mechanisms is responsive, in a specific way, to our judgments about which kinds of considerations constitute rationalizing and justifying reasons for being in states of the relevant sort.     

Switched-words skepticism: A case study in semantical anti-skeptical argument

Conclusion Semantically based arguments play a crucial role in responding to a certain sort of skeptical strategy, a strategy that is widely generalizable, and which is otherwise peculiarly difficult to answer. The anti-skeptical arguments we have been studying do this while avoiding reliance on the insupportable linguistic claims of co-optionism. Instead, they rely on the prevalence of a certain plausible general feature of the semantics of our language. Not surprisingly, this epistemologically important feature is itself frankly epistemological: in essence, we must (typically) be able to tell what a word refers to, in a way independent of the beliefs we use the word to express. In addition to rendering valuable anti-skeptical service, then, the arguments we have been studying display an additional dimension of interest, for they help to illuminate the ways in which our knowledge of the world at large is bound up with our knowledge of a particular part of that world — the language we use to describe it.I would like to thank Joseph Almog, Richard Healey, David Kaplan, Hilary Kornblith, Arthur Kuflik, William E. Mann, Derk Pereboom, George Sher, and a referee forPhilosophical Studies for helpful discussions and comments on earlier drafts.     

All too skeptical theism

Skeptical theism contends that, due to our cognitive limitations, we cannot expect to be able to determine whether there are reasons which justify God’s permission of apparently unjustified evils. Because this is so, the existence of these evils does not constituted evidence against God’s existence. A common criticism is that the skeptical theist is implicitly committed to other, less palatable forms of skepticism, especially moral skepticism. I examine a recent defense against this charge mounted by Michael Bergmann. I point out that the Bergmannian skeptical theist is unable to determine concerning any event or feature of the world whether that feature or event is good or evil all-things-considered. Because of this the skeptical theist must abandon any attempt to act in such a way that the world becomes better rather than worse as a result. These, I claim, are seriously skeptical conclusions, and should cause us to be skeptical about skeptical theism itself.     

CONCEPTS AND OBJECTIVITY

Some philosophers—indeed, a large number—have presented us with a picture of human knowledge which makes it problematic as to whether we can ever be acquainted with an objective world. Given the nature of perception and thought as characterized by, e.g., Descartes and Hume, there is a problem about how anything I can be aware of can have any sort of objective status; there is a problem of how my awareness of anything can amount to anything other than its merely seeming to me that things are thus and so. And of course many of these same philosophers, and other philosophers, have tried in all sorts of different ways to counter this skeptical thrust. Some, like Descartes, have argued that although human perceiving and human thinking are themselves purely subjective affairs, nevertheless the content of some of our thoughts and ideas is such that it (the content) could not exist if there did not also exist certain things of a quite objective nature. Another way of putting Descartes' thesis is to say that although all our concepts of things are, as concepts, purely subjective entities, nevertheless the content of some of our concepts requires that there exist certain objective entities.     

Phenomenal consciousness with infallible self-representation

In this paper, I argue against the claim recently defended by Josh Weisberg that a certain version of the self-representational approach to phenomenal consciousness cannot avoid a set of problems that have plagued higher-order approaches. These problems arise specifically for theories that allow for higher-order misrepresentation or—in the domain of self-representational theories—self-misrepresentation. In response to Weisberg, I articulate a self-representational theory of phenomenal consciousness according to which it is contingently impossible for self-representations tokened in the context of a conscious mental state to misrepresent their objects. This contingent infallibility allows the theory to both acknowledge the (logical) possibility of self-misrepresentation and avoid the problems of self-misrepresentation. Expanding further on Weisberg’s work, I consider and reveal the shortcomings of three other self-representational models—put forward by Kreigel, Van Gulick, and Gennaro—in order to show that each indicates the need for this sort of infallibility. I then argue that contingent infallibility is in principle acceptable on naturalistic grounds only if we attribute (1) a neo-Fregean kind of directly referring, indexical content to self-representational mental states and (2) a certain ontological structure to the complex conscious mental states of which these indexical self-representations are a part. In these sections I draw on ideas from the work of Perry and Kaplan to articulate the context-dependent semantic structure of inner-representational states.     

Sensitivity,Safety, and Brains in Vats

Both sensitivity and safety theorists concur that their accounts should be relativized to the same method that one employs in the actual world. However, properly individuating methods has proven to be a tricky matter. In this regard, Nozick (Philosophical Explanations, Harvard University Press, Cambridge, 1981) proposes a Same-Experience-Same-Method Principle: if the experiences associated with two method tokens are the same, they are of the same type of method. This principle, however, has been widely rejected by recent safety and sensitivity theorists. In this paper, I raise an argument in favor of Nozick: not endorsing the principle leads to some rather implausible consequences when certain skeptical scenarios are considered—i.e., scenarios in which skeptical possibilities are ‘close’. Additionally, this argument reveals some important lessons about skepticism in general and the place of modal accounts of knowledge in the internalism/externalism debate.

     

An old problem for the new rationalism

A well known skeptical paradox rests on the claim that we lack warrant to believe that we are not brains in a vat (BIVs). The argument for that claim is the apparent impossibility of any evidence or argument that we are not BIVs. Many contemporary philosophers resist this argument by insisting that we have a sort of warrant for believing that we are not BIVs that does not require having any evidence or argument. I call this view ‘New Rationalism’. I argue that New Rationalists are committed to there being some evidence or argument for believing that we are not BIVs anyway. Therefore, New Rationalism, since its appeal is that it purportedly avoids the problematic commitment to such evidence or argument, undermines its own appeal. We cannot avoid the difficult work of coming up with evidence or argument by positing some permissive sort of warrant.     

On Categories and A Posteriori Necessity: A Phenomenological Echo

This article argues for two related theses. First, it defends a general thesis: any kind of necessity, including metaphysical necessity, can only be known a priori. Second, however, it also argues that the sort of a priori involved in modal metaphysical knowledge is not related to imagination or any sort of so‐called epistemic possibility. Imagination is neither a proof of possibility nor a limit to necessity. Rather, modal metaphysical knowledge is built on intuition of philosophical categories and the structures they form.     

A Refutation of Skeptical Theism

Skeptical theists argue that no seemingly unjustified evil (SUE) could ever lower the probability of God's existence at all. Why? Because God might have justifying reasons for allowing such evils (JuffREs) that are undetectable. However, skeptical theists are unclear regarding whether or not God's existence is relevant to the existence of JuffREs, and whether or not God's existence is relevant to their detectability. But I will argue that, no matter how the skeptical theist answers these questions, it is undeniable that the skeptical theist is wrong; SUEs lower the probability of God's existence. To establish this, I will consider the four scenarios regarding the relevance of God's existence to the existence and detectability of JuffREs, and show that in each—after we establish our initial probabilities, and then update them given the evidence of a SUE—the probability of God's existence drops.     

Platonic Knowledge and the Standard Analysis

Abstract

In this paper I explore Plato’s reasons for his rejection of the so‐called standard analysis of knowledge as justified true belief. I argue that Plato held that knowledge is an infallible mental state in which (a) the knowable is present in the knower and (b) the knower is aware of this presence. Accordingly, knowledge (epistēmē) is non‐propositional. Since there are no infallible belief states, the standard analysis, which assumes that knowledge is a type of belief, cannot be correct. In addition, I argue that Plato held that belief (doxa) is only possible for the sort of being capable of knowledge. This is because self‐reflexivity is necessary for infallible knowledge and self‐reflexivity is only possible if the intellect is immaterial. This capacity for self‐reflexivity is also essential for belief, since beliefs are, paradigmatically, not dispositions but self‐reflexive mental states.     

Skeptical theism,moral skepticism,and epistemic propriety

Respondents to the argument from evil who follow Michael Bergmann’s development of skeptical theism hold that our failure to determine God’s reasons for permitting evil does not disconfirm theism (i.e. render theism less probable on the evidence of evil than it would be if merely evaluated against our background knowledge) at all. They claim that such a thesis follows from the very plausible claim that (ST) we have no good reason to think our access to the realm of value is representative of the full realm of value. There are two interpretations of ST’s strength, the stronger of which leads skeptical theists into moral skepticism and the weaker of which fails to rebut the argument from evil. As I demonstrate, skeptical theists avoid the charge of moral skepticism while also successfully rebutting the argument from evil only by embracing an equivocation between these two interpretations of ST. Thus, as I argue, skeptical theists are caught in a troubling dilemma: they must choose between moral skepticism and failure to adequately respond to the argument from evil.     

Assertion,belief, and context

This paper argues for a treatment of belief as essentially sensitive to certain features of context. The first part gives an argument that we must take belief to be context-sensitive in the same way that assertion is, if we are to preserve appealing principles tying belief to sincere assertion. In particular, whether an agent counts as believing that p in a context depends on the space of alternative possibilities the agent is considering in that context. One and the same doxastic state may amount to belief that p in one context but not another. The second part of the paper gives a formal treatment of doxastic states, according to which belief is context-sensitive along just these lines. The model is applied to characterize (but not to refute) skeptical arguments.     

Knowing The World By Knowing One's Mind

This paper addresses the question whetherintrospection plus externalism about mental contentwarrant an a priori refutation of external-worldskepticism and ontological solipsism. The suggestionis that if thought content is partly determined byaffairs in the environment and if we can havenon-empirical knowledge of our current thoughtcontents, we can, just by reflection, know about theworld around us – we can know that our environment ispopulated with content-determining entities. Afterexamining this type of transcendental argument anddiscussing various objections found in the literature,I argue that the notion of privileged self-knowledgeunderlying this argument presupposes that we canlearn, via introspection, that our so-called thoughtsare propositional attitudes rather than contentlessstates. If, however, externalism is correct andthought content consists in the systematic dependencyof internal states on relational properties, we cannotknow non-empirically whether or not we havepropositional attitudes. Self-knowledge (apropositional attitude) is consistent with us lackingthe ability to rule out, via introspection, thepossibility that we don't have any propositionalattitudes. Self-knowledge provides us with knowledgeof what is in our minds, but not that we haveminds. Hence, the combination of externalism with thedoctrine of privileged self-knowledge does not allowfor an a priori refutation of skepticism and istherefore unproblematic.
