I argue that there are no irrational visual experiences, if we mean just the experiences that one is having now, but there are irrational visual experiences, if we mean also the experiences that one has had in the past. In other words, I will be arguing that perceptual irrationality is a retrospective phenomenon. So as to further support the first conjunct of my thesis, and to contextualize it among contemporary discussions, I also critique Susanna Siegel’s proposal that one could be (...) having an irrational experience, in the sense of a hijacked experience that has inherited a sub-threshold epistemic charge from a corrupt outlook. The present discussion is conducted from a Husserlian point of view, according to which perception is rational, rather than arational. I am, however, in this paper, not undertaking to defend the Husserlian view or the rationality of perception, or even to argue that the view I refer to as Husserlian is, in all aspects, the view that Edmund Husserl actually held. I aim merely to provide certain clarifications concerning the more specific topic of irrational visual experiences. (shrink)

Debunking arguments aim to undermine common sense beliefs by showing that they are not explanatorily or causally linked to the entities they are purportedly about. Rarely are facts about the aetiology of common sense beliefs invoked for the opposite aim, that is, to support the reality of entities that furnish our manifest image of the world. Here I undertake this sort of un-debunking project. My focus is on the metaphysics of ordinary physical objects. I use the view of perception as (...) approximate Bayesian inference to show how representations of ordinary objects can be extracted from sensory input in a rational and truth-tracking manner. Drawing an analogy between perception construed as Bayesian hypothesis testing and scientific inquiry, I sketch out how some of the intuitions that traditionally inspired arguments for scientific realism also find application with regards to proverbial tables and chairs.

The present paper investigates the first step of rational belief acquisition. It, thus, focuses on justificatory relations between perceptual experiences and perceptual beliefs, and between their contents, respectively. In particular, the paper aims at outlining how it is possible to reason from the content of perceptual experiences to the content of perceptual beliefs. The paper thereby approaches this aim by combining a formal epistemology perspective with an eye towards recent advances in philosophy of cognition. Furthermore the paper restricts its focus, (...) it concentrates on the case of color perception and perceptual beliefs about color. (shrink)

Dispositionalism about belief has had a recent resurgence. In this paper we critically evaluate a popular dispositionalist program pursued by Eric Schwitzgebel. Then we present an alternative: a psychofunctional, representational theory of belief. This theory of belief has two main pillars: that beliefs are relations to structured mental representations, and that the relations are determined by the generalizations under which beliefs are acquired, stored, and changed. We end by describing some of the generalizations regarding belief acquisition, storage, and change.

ABSTRACTThis paper provides a naturalistic account of inference. We posit that the core of inference is constituted by bare inferential transitions, transitions between discursive mental representations guided by rules built into the architecture of cognitive systems. In further developing the concept of BITs, we provide an account of what Boghossian [2014] calls ‘taking’—that is, the appreciation of the rule that guides an inferential transition. We argue that BITs are sufficient for implicit taking, and then, to analyse explicit taking, we posit (...) rich inferential transitions, which are transitions that the subject is disposed to endorse.

As an important view in the epistemology of perception, dogmatism proposes that for any experience, if it has a distinctive kind of phenomenal character, then it thereby provides us with immediate justification for beliefs about the external world. This paper rejects dogmatism by looking into the epistemology of imagining. In particular, this paper first appeals to some empirical studies on perceptual experiences and imaginings to show that it is possible for imaginings to have the distinctive phenomenal character dogmatists have in (...) mind. Then this paper argues that some of these imaginings fail to provide us with immediate justification for beliefs about the external world at least partly due to their inappropriate etiology. Such imaginings constitute counterexamples to dogmatism. (shrink)

Terence Horgan and John Tienson argue that there is phenomenal intentionality, i.e., “a kind of intentionality, pervasive in human mental life, that is constitutively determined by phenomenology alone” (p. 520). However, their arguments are open to two lines of objection. First, Horgan and Tienson are not sufficiently clear as to what kind of content it is that they take to be determined by, or to supervene on, phenomenal character. Second, critics have objected that, for their conclusion to follow, Horgan and (...) Tienson would first have to establish the co-variation of phenomenology and intentional content, but even so, phenomenal intentionality would still emerge as less plausible than its converse, representationalism. I will address these two challenges by appeal to Husserlian ideas. A consideration of perceptual phenomenology (i.e., phenomenal character) shows that there is a kind of perceptual content that is, indeed, determined by phenomenal character. Such content is conceived in terms of fulfillment conditions, or what it takes to bring aspects of objects and scenes to different, and more complete, ways of givenness. We can establish the primacy of phenomenology, relative to such fulfillment-conditional content, by tracing it back to the basic phenomenology of visual and other sensations. (shrink)

Part of a symposium on *The Rationality of Perception* by Susanna Siegel (2017 Oxford University Press).

This paper examines how new evil demon problems could arise for our access to the internal world of our own minds. I start by arguing that the internalist/externalist debate in epistemology has been widely misconstrued---we need to reconfigure the debate in order to see how it can arise about our access to the internal world. I then argue for the coherence of scenarios of radical deception about our own minds, and I use them to defend a properly formulated internalist view (...) about our access to our minds. The overarching lesson is that general epistemology and the specialized epistemology of introspection need to talk---each has much to learn from each other. (shrink)

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. (shrink)

In this short essay, I tackle, yet again, the question of the nature of inference and elaborate on the agential conception of inference that I've been pursuing (Boghossian 2014, 2016 and forthcoming). What's new in this essay is a better way of setting up the issue about the na- ture of inference; a better identification of the concerns that lie at the back of this way of thinking about the topic; and a response to some important criticisms that have been (...) made of the agential view I've been advocating.

Predictive approaches to the mind claim that perception, cognition, and action can be understood in terms of a single framework: a hierarchy of Bayesian models employing the computational strategy of predictive coding. Proponents of this view disagree, however, over the extent to which perception is direct on the predictive approach. I argue that we can resolve these disagreements by identifying three distinct notions of perceptual directness: psychological, metaphysical, and epistemological. I propose that perception is plausibly construed as psychologically indirect on (...) the predictive approach, in the sense of being constructivist or inferential. It would be wrong to conclude from this, however, that perception is therefore indirect in a metaphysical or epistemological sense on the predictive approach. In the metaphysical case, claims about the inferential properties of constructivist perceptual mechanisms are consistent with both direct and indirect solutions to the metaphysical problem of perception (e.g. naïve realism, representationalism, sense datum theory). In the epistemological case, claims about the inferential properties of constructivist perceptual mechanisms are consistent with both direct and indirect approaches to the justification of perceptual belief. In this paper, I demonstrate how proponents of the predictive approach have conflated these distinct notions of perceptual directness and indirectness, and I propose alternative strategies for developing the philosophical consequences of the approach.

In her exciting and thought-provoking book, The Rationality of Perception, Susanna Siegel tackles some bedrock issues concerning the nature and epistemology of perception: its rationality and relation to inference. Examining those issues from the perspective of everyday perception, where our vanity, fears, wishful thinking, general outlook, etc. can influence what we believe ourselves to see, Siegel offers a constructive defence of the claim that ‘both perceptual experiences and the processes by which they arise can be rational or irrational’ and goes (...) on to analyze these processes in terms of inference.
