ABSTRACT
This chapter considers the structure of perceptual experience. It is important to present at least a basic or general outline of such structure in order to consider the possible ways in which experience can be in error under different positions on time. It is common in the philosophy of perception to treat 'experience' as identical to 'perceptual experience'. It is also common to discuss perceptual illusions when talking about errors of experience. Considerations about non-perceptual experiences opens up the possibility that there are illusions which are not perceptual illusions. This is because, even if what we experience is not present, how it seems can still be mistaken. To discuss the spatial and temporal structure of experience, it is necessary to introduce two general concepts. These concepts have specific analogues in particular debates about the mind. The chapter concerns three possible features of experience that descriptions and explanations of perceptual experience may include.
