Abstract
In what follows I wish to raise and eventually to suggest an answer to the following question: What is the rationality of human communication? Why should we ask this question? By way of a first approach I would place the problem within the context of the so called “pragmatic turn” of analytic philosophy, i.e. within a context in which the concept of the rationality of logical syntactics and logical semantics of language systems has been integrated into, or superseded by, the rationality concept of the human use of language—say, e.g., of arguments.
