E = K and Non-Epistemic Perception

Quite plausibly, epistemic justification and rationality is tied to possession of evidence. According to Williamson, one’s evidence is what one knows. This is not compatible with non-epistemic perception, however, since non-epistemic perception does not require belief in what one perceives and, thus, does not require knowledge of the evidence – and, standardly, knowledge does require belief. If one non-epistemically perceives a piece of evidence, this can be sufficient for possessing it as evidence. Williamson’s arguments for the necessity of belief will be discussed and rebutted. Interestingly, the view that non-epistemic perception is sufficient for possession of evidence can allow for conceptual or non-conceptual content of perception and it provides the framework for a neo-foundationalist account of epistemic justification.
