Semiotics... is not concerned with the study of a particular kind of object, but with ordinary objects in so far (and only in so far) as they participate in semiosis.

There are, then, syntactical problems in the fields of perceptual signs, aesthetic signs, the practical use of signs, and general linguistics which have not been treated within the framework of what today is regarded as logical syntax and yet which form part of syntactics as this is here conceived.

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.

What of the term 'meaning'? In the preceding discussion the term 'meaning' has been deliberately avoided. In general it is well to avoid this term in discussions of signs; theoretically, it can be dispensed with entirely and should not be incorporated into the language of semiotic. But since the term has had such a notorious history, and since in its consideration certain important implications of the present account can be made clear, the present section is devoted to its discussion.

Empirical problems of a nonlinguistic sort are not solved by linguistic considerations, but it is important that the two kinds of problems not be confused and that nonlinguistic problems be expressed in such a form as aids their empirical solution.

The Encyclopedia presents a contemporary version of the ancient encyclopedic ideal of Aristotle, the Scholastics, Leibniz, the Encyclopedists, and Comte.

In Foundations of the Theory of Signs (p. 6), the three terms in question were defined follows: pragmatics as the study of "the relation of signs to interpreters", semantics as the study of "the relations of signs to the objects to which the signs are applicable", syntactics as the study of "the formal relations of signs to one another."
