Any theory of philosophie discourse based on the naive opposition between language and speech, language and discourse, seems to encounter the classic question: is philosophic discourse governed —to what extent and in what ways—by the constraints of language? In other words, if we consider the history of philosophy as one great discourse, a powerful discursive chain, isn't it immersed in a reservoir of language, the systematic fund of a lexicology, a grammar, a group of signs and values? From then on, isn't it limited by the devices and organization of that reservoir?
