This article intends to demonstrate that the Project of a Psychology, written by Freud in 1895, is a metaphor. It corresponds to the first attempt made by Freud to produce a general theory of the psyche, in which we encounter a metapsychology formulated in biological terms. It is defended that this metapsychology is not proposed as a neuropsychology, but as a set of auxiliary constructions, speculative in nature, whose value is only heuristic, applicable to problems of psychic nature related to the method of treatment that Freud was developing.
