Abstract

Brentano’s philosophy of perception has often been understood as a special chapter of his theory of intentionality. If all and only mental phenomena are constitutively intentional, and if perceptual experience is mental by definition, then all perceptual experiences are intentional experiences. I refer to this conception as the “standard view” of Brentano’s account of perception. Different options are available to support the standard view: a sense-data theory of perception; an adverbialist account; representationalism. I argue that none of them are real options for the standard view. I suggest that Brentano’s conception of optical illusions introduces a presupposition that not only challenges the standard view - the distinction between the subjectively and objectively given - but that also makes his account more palatable for a naive understanding of perception as openness to and awareness of the world.
