Abstract
This essay deals with epistemological issues concerning perception. These can be briefly indicated by the question: “How, if at all, is perception a source of knowledge or justified belief?” To keep a discussion of a very complex subject matter within prescribed bounds, I will mostly focus on the “justified belief” side of the above disjunction, bringing in questions about perceptual knowledge only when dealing with a position that is specially concerned with knowledge. There are some other housekeeping moves to be made before we can get under way.
