An epistemic argument for liberalism about perceptual content

This paper concerns the question of which properties figure in the contents of perceptual experience. According to conservatives, only low-level properties figure in the contents of perceptual experience. Liberals, on the other hand, claim that high-level properties, such as natural kind properties, artifacts, and even moral properties, can figure in the contents of perceptual experience. I defend a novel argument in favor of liberalism, the Epistemic Argument, which hinges on two crucial claims. The first is that many perceptual experiences of even neurotypical human beings can justify beliefs in high-level properties without providing justification for their low-level constituents. The second claim, roughly, is that any experience that alone provides (defeasible) justification for beliefs about some property p, other things being equal, has p as part of its content. In short, certain perceptual experiences represent high-level but not low-level properties, which entails that liberalism is true.     

A Posteriori Ethical Intuitionism and the Problem of Cognitive Penetrability

According to a posteriori ethical intuitionism (AEI), perceptual experiences can provide non‐inferential justification for at least some moral beliefs. Moral epistemology, for the defender of AEI, is less like the epistemology of math and more like the epistemology of tables and chairs. One serious threat to AEI comes from the phenomenon of cognitive penetration. The worry is that even if evaluative properties could figure in the contents of experience, they would only be able to do so if prior cognitive states influence perceptual experience. Such influences would undermine the non‐inferential, foundationalist credentials of AEI. In this paper, I defend AEI against this objection. Rather than deny that cognitive penetration exists, I argue that some types of cognitive penetrability are actually compatible with AEI's foundationalist structure. This involves teasing apart the question of whether some particular perceptual process has justification‐conferring features from the question of how it came to have those features in the first place. Once this distinction is made, it becomes clear that some kinds of cognitive penetration are compatible with the non‐inferential status of moral perceptual experiences as the proponent of AEI claims.     

Circularity and epistemic principles: A reply to James Keller

This paper is a reply to James Keller's criticisms of my Foundationalism, Coherentism and the Levels Gambit (Synthese 55, April 1983).Foundationalists have often claimed that, within a foundationalist framework, one can justify beliefs about epistemic principles in a mediate, empirical fashion, while escaping the charge of vicious circularity that is usually thought to afflict such methods of justification. In my original paper I attacked this foundationalist strategy; I argued that once mediate, empirical justification of epistemic principles is allowed, the foundationalist must also allow circular patterns of justification of the sort that he typically criticizes coherentists for espousing. Here I argue that Keller's reply only makes matters worse for the foundationalist. At several points, his reply turns out to be inconsistent either with reliabilism or with the foundationalist strategy he is trying to defend.I am indebted to Professor Keller for helpful correspondence.     

A critique of Plantinga's theological foundationalism

Conclusion 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.

Rights

Liberals claim that some perceptual experiences give us immediate justification for certain perceptual beliefs. Conservatives claim that the justification that perceptual experiences give us for those perceptual beliefs is mediated by our background beliefs. In his recent paper ‘Basic Justification and the Moorean Response to the Skeptic’, Nico Silins successfully argues for a non-Moorean version of Liberalism. But Silins's defence of non-Moorean Liberalism leaves us with a puzzle: why is it that a necessary condition for our perceptual experiences to justify us in holding certain perceptual beliefs is that we have some independent justification for disbelieving various sceptical hypotheses? I argue that the best answer to this question involves commitment to Crispin Wright's version of Conservatism. In short, Wright's Conservatism is consistent with Silins's Liberalism, and the latter helps to give us grounds for accepting the former.     

Toward a Noninferentialist,Nonreliabilist Account of Perceptual Justification

While it may be a datum of common sense that perceptual experiences can justify beliefs, there is no clear consensus about how they can do so. According to what I call “inferentialism,” perceptual experiences can justify beliefs because perceptual experiences have propositional contents and thus can serve as reasons for belief. A critical commitment of inferentialism is that justification requires the obtaining of a nonarbitrary or nonaccidental semantic relation between justifier and justified, a requirement that I call semantic appropriateness (SA). By contrast, reliabilists reject SA and argue that perceptual experiences can justify beliefs because perceptual experiences are part of a reliable belief‐forming process. In this paper, I explore whether a commitment to SA inevitably leads to a commitment to inferentialism. This exploration is largely motivated by doubts over whether perceptual experiences have propositional contents. If those doubts prove to be well‐founded, then it seems either that perceptual experiences cannot justify beliefs or that some form of reliabilism is true. I argue that although we should take the doubts seriously, there is a way to make sense of SA that does not require inferentialism.     

Experience and the Space of Reasons: The Problem of Non-Doxastic Justification

It is not difficult to make sense of the idea that beliefs may derive their justification from other beliefs. Difficulties surface when, as in certain epistemological theories, one appeals to sensory experiences to give an account of the structure of justification. This gives rise to the so-called problem of ‘nondoxastic justification’, namely, the problem of seeing how sensory experiences can confer justification on the beliefs they give rise to. In this paper, I begin by criticizing a number of theories that are currently on offer. Finding them all wanting, I shall then offer a diagnosis of why they fail while gesturing towards a promising way of resolving the dispute. It will be argued that what makes the problem of nondoxastic justification a hard one is the difficulty of striking the right balance between a notion of normative justification that is content-sensitive and truth conducive and the possibility of error while acknowledging the fact that our experiences can justify our beliefs in cases we are hallucinating.

Perceptual Justification and Warrant by Default

As I use the term, ‘entitlement’ is any warrant one has by default—i.e. without acquiring it. Some philosophers not only affirm the existence of entitlement, but also give it a crucial role in the justification of our perceptual beliefs. These philosophers affirm the Entitlement Thesis: that an essential part of what makes our perceptual beliefs justified is our entitlement to the proposition that I am not a brain-in-a-vat. Crispin Wright, Stewart Cohen and Roger White are among those who endorse this controversial claim. In this paper, I argue that the Entitlement Thesis is false.     

Internalistic foundationalism and the justification of memory belief

In this paper I argue that internalistic foundationalist theories of the justification of memory belief are inadequate. Taking a discussion of John Pollock as a starting point, I argue against any theory that requires a memory belief to be based on a phenomenal state in order to be justified. I then consider another version of internalistic foundationalism and claim that it, too, is open to important objections. Finally, I note that both varieties of foundationalism fail to account for the epistemic status of our justified nonoccurrent beliefs, and hence are drastically incomplete.     

Do looks constitute our perceptual evidence?

Many philosophers take experience to be an essential aspect of perceptual justification. I argue against a specific variety of such an experientialist view, namely, the Looks View of perceptual justification, according to which our visual beliefs are mediately justified by beliefs about the way things look. I describe three types of cases that put pressure on the idea that perceptual justification is always related to looks‐related reasons: unsophisticated cognizers, multimodal identification, and amodal completion. I then provide a tentative diagnosis of what goes wrong in the Looks View: it ascribes a specific epistemic role to beliefs about looks that is actually fulfilled by subpersonal perceptual processes.     

The Mystery of Direct Perceptual Justification

In at least some cases of justified perceptual belief, our perceptual experience itself, as opposed to beliefs about it, evidences and thereby justifies our belief. While the phenomenon is common, it is also mysterious. There are good reasons to think that perceptions cannot justify beliefs directly, and there is a significant challenge in explaining how they do. After explaining just how direct perceptual justification is mysterious, I considerMichael Huemer’s (Skepticism and the Veil of Perception, 2001) and Bill Brewer’s (Perception and Reason, 1999) recent, but radically different, attempts to eliminate it. I argue that both are unsuccessful, though a consideration of their mistakes deepens our appreciation of the mystery.     

Grounds and limits: Reichenbach and foundationalist epistemology

From 1929 onwards, C. I. Lewis defended the foundationalist claim that judgements of the form ‘x is probable’ only make sense if one assumes there to be a ground y that is certain (where x and y may be beliefs, propositions, or events). Without this assumption, Lewis argues, the probability of x could not be anything other than zero. Hans Reichenbach repeatedly contested Lewis’s idea, calling it “a remnant of rationalism”. The last move in this debate was a challenge by Lewis, defying Reichenbach to produce a regress of probability values that yields a number other than zero. Reichenbach never took up the challenge, but we will meet it on his behalf, as it were. By presenting a series converging to a limit, we demonstrate that x can have a definite and computable probability, even if its justification consists of an infinite number of steps. Next we show the invalidity of a recent riposte of foundationalists that this limit of the series can be the ground of justification. Finally we discuss the question where justification can come from if not from a ground.     

Do you see what I know? On reasons,perceptual evidence,and epistemic status

Our epistemology can shape the way we think about perception and experience. Speaking as an epistemologist, I should say that I don't necessarily think that this is a good thing. If we think that we need perceptual evidence to have perceptual knowledge or perceptual justification, we will naturally feel some pressure to think of experience as a source of reasons or evidence. In trying to explain how experience can provide us with evidence, we run the risk of either adopting a conception of evidence according to which our evidence isn't very much like the objects of our beliefs that figure in reasoning (e.g., by identifying our evidence with experiences or sensations) or the risk of accepting a picture of experience according to which our perceptions and perceptual experiences are quite similar to beliefs in terms of their objects and their representational powers. But I think we have good independent reasons to resist identifying our evidence with things that don't figure in our reasoning as premises and I think we have good independent reason to doubt that experience is sufficiently belief‐like to provide us with something premise‐like that can figure in reasoning. We should press pause. We shouldn't let questionable epistemological assumptions tell us how to do philosophy of mind. I don't think that we have good reason to think that we need the evidence of the senses to explain how perceptual justification or knowledge is possible. Part of my scepticism derives from the fact that I think we can have kinds of knowledge where the relevant knowledge is not evidentially grounded. Part of my scepticism derives from the fact that there don't seem to be many direct arguments for thinking that justification and knowledge always requires evidential support. In this paper, I shall consider the three arguments I've found for thinking that justification and knowledge do always require evidential support and explain why I don't find them convincing. I think that we can explain perceptual justification, rationality, and defeat without assuming that our experiences provide us with evidence. In the end, I think we can partially vindicate Davidson's (notorious) suggestion that our beliefs, not experiences, provide us with reasons for forming further beliefs. This idea turns out to be compatible with foundationalism once we understand that foundational status can come from something other than evidential support.     

Foundationalism,circular justification,and the levels gambit

In Foundationalism, Coherentism, and the Levels Gambit, David Shatz argued that foundationalists must countenance a circular mediate justification of perceptual beliefs which the foundationalist holds are already immediately justified. Because the circularity of coherentist accounts of the justification of beliefs is a major basis of foundationalist criticism of coherentism, Shatz's claim is a serious challenge to foundationalism. In this paper, using a moderate foundationalism with a reliabilist conception of justification, I give an account of immediately and mediately justified beliefs which shows that such a foundationalism need not accept such a circular justification (and in crucial cases cannot do so) and that Shatz's claim is therefore incorrect.     

GOD AND THE EXTERNAL WORLD

There are a number of apparent parallels between belief in God and belief in the existence of an external world beyond our experiences. Both beliefs would seem to condition one's overall view of reality and one's place within it – and yet it is difficult to see how either can be defended. Neither belief is likely to receive a purely a priori defence and any empirical evidence that one cites either in favour of the existence of God or the existence of the external world would seem to blatantly beg the question against a doubter. I will explore just how far this parallel can be pushed by examining some strategies for resisting external world scepticism 1 .     

Perception and the external world

In this paper, I argue that perception justifies belief about the external world in virtue of its phenomenal character together with its relations to the external world. But I argue that perceptual relations to the external world impact on the justifying role of perception only by virtue of their impact on its representational content. Epistemic level-bridging principles provide a principled rationale for avoiding more radically externalist theories of perceptual justification.     

Epistemic Elitism and Other Minds

Experiences justify beliefs about our environment. Sometimes the justification is immediate: seeing a red light immediately justifies believing there is a red light. Other times the justification is mediate: seeing a red light justifies believing one should brake in a way that is mediated by background knowledge of traffic signals. How does this distinction map onto the distinction between what is and what isn't part of the content of experience? Epistemic egalitarians think that experiences immediately justify whatever is part of their content. Epistemic elitists deny this and think that there is some further constraint the contents of experience must satisfy to be immediately justified. Here I defend epistemic elitism, propose a phenomenological account of what the further constraint is, and explore the resulting view's consequences for our knowledge of other minds, and in particular for perceptual theories of this knowledge.     

The Role of Sensory Experience in Epistemic Justification: a Problem for Coherentism

The author argues that coherence views of justification, in spite of their crucial insight into the interpenetration of our beliefs, neglect a key constraint on justification: they are unable to accommodate the epistemic significance of experience. Epistemic justification is not just a function of our beliefs and their interrelations. Both, beliefs and experiences, are relevant to the justification of an empirical belief. Experience is not itself a form of belief or disposition to believe; it cannot be analyzed in doxastic terms. And, yet, nondoxastic experiences play a justificatory role, not merely a causal role. The positive epistemic status of a perceptual belief depends upon being appeared to in appropriate ways. It is important that, for an ordinary perceptual belief to be justified, one does not have to believe that one is appeared to in these ways. It is the experiences themselves, the ways of being appeared to, not our beliefs about them, that are required for justification.     

Perceptual Skill And Social Structure

Visual perception relies on stored information and environmental associations to arrive at a determinate representation of the world. This opens up the disturbing possibility that our visual experiences could themselves be subject to a kind of racial bias, simply in virtue of accurately encoding previously encountered environmental regularities. This possibility raises the following question: what, if anything, is wrong with beliefs grounded upon these prejudicial experiences? They are consistent with a range of epistemic norms, including evidentialist and reliabilist standards for justification. I argue that we will struggle to locate a flaw with these sorts of perceptual beliefs so long as we focus our analysis at the level of the individual and her response to information. We should instead broaden our analysis to include the social structure within which the individual is located. Doing so lets us identify a problem with the way in which unjust social structures in particular “gerrymander” the regularities an individual is exposed to, and by extension the priors their visual system draws on. I argue that in this way, social structures can cap perceptual skill.     

Reply to Kurth,Crosby, and Basse’s review of Emotions,Values, and Agency

In this reply, I argue that the worries raised by Kurth and this coauthors are not fatal for the perceptual theory of emotions. A first point to keep in mind in discussing the analogy argument in favor of that account is that what counts is the overall balance of similarities and differences, given their respective weight. In any case, I argue that none of the alleged differences between sensory perceptual experiences and emotions are such as to rule out that emotions are a kind of perceptual experience which can confer epistemic justification of our evaluative beliefs. Finally, I suggest that the perceptual theory is in a position to nicely capture what happens when we disagree about evaluative issues.
