This is a collection of work on perception written between 1999 and 2012. Chapters discuss the relation between perception and thought, between perception and representation, between perception and perceptual experience which is not perception, and between perception and sub-personal processing. It draws heavily on ideas of Frege, in the first instance having to do for him with distinguishing perceptual experience and its objects from thought and its objects. Broadly speaking, the chapters defend a disjunctivist conception of perception, oppose the idea that perception has representational content, explore the appeal of the idea of sense data, and explore various conceptions of modes of presentation of oneself (and one’s own perceptual experience).
