I share the conviction held by many others that the movement of thought called "symbolism" is of great significance. Not only does this movement cut across the traditional lines of division among philosophers, but it coordinates in a remarkable way the work of linguists, sociologists, psychologists, anthropologists, and biologists, in so far as their work connects with the topic of mind. In the degree that the symbolic movement is significant, a work which develops systematically the basis of the movement, and at the same time applies this analysis to the topic of mind and to certain basic philosophical problems, can at least claim to be an important contribution to critical thought. Whether the claim is substantiated depends, of course, on the quality of the work itself.

The process in which something functions as a sign may be called . This process, in a tradition which goes back to the Greeks, has commonly been regarded as involving three (or four) factors: that which acts as a sign, that which the sign refers to, and the effect on some interpreter in virtue of which the thing in question is a sign to that interpreter. These three components in semiosis may be called, respectively, the sign vehicle, the designatum, and the interpretant; the interpreter may be included as a fourth factor. These terms make explicit the factors left undesignated in the common statement that a sign refers to something for someone.

The full characterization of a language may now be given: A language in the full semiotic sense of the term is any intersubjective set of sign vehicles whose usage is determined by syntactical, semantical, and pragmatical rules.
