Philosophers of perception frequently assume that we see actual states of affairs, or facts. Call this claim factualism. In his book, William Fish suggests that factualism is supported by phenomenological observation as well as by experimental studies on multiple object tracking and dynamic feature-object integration. In this paper, I examine the alleged evidence for factualism, focusing mainly on object detection and tracking. I argue that there is no scientific evidence for factualism. This conclusion has implications for studies on the phenomenology (...) and epistemology of visual perception. (shrink)

Starting with Gareth Evans, there’s an important tradition of theorizing about perception-based demonstrative thought which assigns necessary epistemic conditions to it. Its core idea is that demonstrative reference in thought is grounded in information links, understood as links which carry reliable information about their targets and which a subject exploits for demonstrative reference by tokening the mental files fed by these links. Perception, on these views, is not fundamental to perception-based demonstrative thought but is only the information link exploited in (...) these cases. Evans himself assigns a further epistemic condition, while more recently Imogen Dickie has expanded the reliability requirement into a more complex account centered around justification. In this paper I synthesize three central proponents of this approach and show that the epistemic conditions they place on perception-based demonstrative thought are not actually required. My argument gives two examples in which there is perceptual contact with an object but this perceptual contact fails to do the epistemic work in question. The first case is stimulus-incorporating dream experiences, the second involves multimodal binding failures. I argue that this perceptual contact still affords demonstrative thought in these cases.

Austere relationism rejects the orthodox analysis of hallucinations and illusions as incorrect perceptual representations. In this article, I argue that illusions of optimal motion present a serious challenge for this view. First, I submit that austere-relationist accounts of misleading experiences cannot be adapted to account for IOMs. Second, I show that any attempt at elucidating IOMs within an austere-relationist framework undermines the claim that perceptual experiences fundamentally involve relations to mind-independent objects. Third, I develop a representationalist model of IOMs. The (...) proposed analysis combines two ideas: Evans' dynamic modes of presentation and Fine's relational semantics for identity. (shrink)
