Abstract
According to H. H. Price, there have been two major approaches to understanding what it is to have a concept: the classical theory and the symbolist theory. The classical theory, whose heritage extends at least to Plato, takes having a concept to be a relation to a special sort of object, usually called a concept or universal. The kind of relation the thinking mind has to this object is most often conceived as analogous to sight, a version of the classical theory which Price calls inspectivism.
