Abstract

Seeing a rose or hearing the doorbell is among the most common and immediate of experiences. Sense perceptions are also most fundamental and important; on them base all our factual knowledge and empirical science. Does their epistemological priority stem from their being unanalyzable primitives given to us? Do they have structures? If so, what are the structures and where do they come from? The importance of these questions extends beyond psychology to the justification of all knowledge and science.
