Some attempts to develop a language without intensional contexts are considered. Wittgenstein’s “Tractatus Logico-Philosophicus” was a guide sign for such a program, and its careful justification was given by Carnap in his “Meaning and Necessity”. Extensional language would have made possible methodical abstraction from the agents’ sel fun derstanding and the use of solely meta-language in social science. Some examples demonstrate, however, that this program was a failure, and that solution of intensional statements problem is impossible unless a context of (possible) communication of a subject of inquiry and its object is presupposed.
