Abstract

TWO OPPOSING VIEWS ABOUT THE RELATIONSHIP between concepts and the world can be found in the history of philosophy. One view—deriving from Immanuel Kant and endorsed by Karl Popper, among many others—claims that in forming and using concepts we structure the world. Concepts produce or increase order. Hence, the world, insofar as it is knowable by human beings, is necessarily a conceptually structured world. The second, still older view—represented by the Aristotelian tradition and by John Locke, for example—holds that concepts are formed by abstracting from the particularities of the world. By leaving out the accidental or irrelevant features of particular entities, we abstract a concept as a general representative of a kind.
