Speaking is an introduction to the philosophy of language from an existential and phenomenological point of view. Gusdorf's central concern is to analyze speech within the context of human reality. Speech is an abstraction, but speaking is not, he says. Speaking expresses the experimental and dialectical relation of man, nature, and society. It is through speaking that nature is sublimated into the meant and expressive world of human reality.
