No Representation without Taxation
Introduction
The physical world reaches us as a continuous mass of sensory data, and yet we experience and reason about the world in terms of discrete representations, which we call concepts. Almost all cognitive activities involve the conversion of raw sensory data to concepts, a process that employs a kind of discrimination-learning called categorization. Categorization is an important aspect of cognition, and much effort has been invested to understand how the "stuff of experience" is categorized and represented in the mind. Since "learning" is the process of categorizing raw inputs into meaningful concepts, it is reasonable to ask: How do the ways in which cognitive representations are developed and learned influence what gets learned and represented?
