I develop and defend the view that subjects are necessarily psychologically able to revise their beliefs in response to relevant counter-evidence. Specifically, subjects can revise their beliefs in response to relevant counter-evidence, given their current psychological mechanisms and skills. If a subject lacks this ability, then the mental state in question is not a belief, though it may be some other kind of cognitive attitude, such as a supposi-tion, an entertained thought, or a pretense. The result is a moderately revisionary (...) view of belief: while most mental states we thought were beliefs are beliefs, some mental states which we thought were beliefs are not beliefs. The argument for this view draws on two key claims: First, subjects are rationally obligated to revise their beliefs in response to relevant counter-evidence. Second, if some subject is rationally obligated to revise one of her mental states, then that subject can revise that mental state, given her current psychological mechanisms and skills. Along the way to defending these claims, I argue that rational obligations can govern activities which reflect on one’s rational character, whether or not those activities are under one’s voluntary control. I also show how the relevant version of epistemic ‘ought’ implies ‘can’ survives an objection which plagues other variants of the principle. (shrink)

I argue that we sometimes visually perceive the intentions of others. Just as we can see something as blue or as moving to the left, so too can we see someone as intending to evade detection or as aiming to traverse a physical obstacle. I consider the typical subject presented with the Heider and Simmel movie, a widely studied ‘animacy’ stimulus, and I argue that this subject mentally attributes proximal intentions to some of the objects in the movie. I further (...) argue that these attributions are unrevisable in a certain sense and that this result can be used to as part of an argument that these attributions are not post-perceptual thoughts. Finally, I suggest that if these attributions are visual experiences, and more particularly visual illusions, their unrevisability can be satisfyingly explained, by appealing to the mechanisms which underlie visual illusions more generally.

Whether we perceive high-level properties is presently a source of controversy. A promising test case for whether we do is aesthetic perception. Aesthetic properties are distinct from low-level properties, like shape and colour. Moreover, some of them, e.g. being serene and being handsome, are properties we appear to perceive. Aesthetic perception also shares a similarity with gestalt effects, e.g. seeing-as, in that aesthetic properties, like gestalt phenomena, appear to ‘emerge’ from low-level properties. Gestalts effects, of course, are widely observed, which (...) raises the question: do gestalt effects make it plausible that we perceive high-level aesthetic properties? Contra Stokes, this paper argues that they don’t. This is interesting in its own right, but it also points to a more general lesson, namely we should resist the temptation to appeal to gestalt effects to argue for high-level perception. (shrink)
