In order to understand the Freudian concepts, one must set out on the basis that it is the subject who is called-the subject of Cartesian origin. This basis gives its true function to what, in analysis, is called recollection or remembering. Recollection is not Platonic reminiscence -it is not the return of a form, an imprint, a eidos of beauty and good,a supreme truth, coming to us from the beyond. It is something that comes to us from the structural necessities, something humble, born at the level of the lowest encounters and of all the talking crowd that precedes us, at the level of the structure of the signifier, of the languages spoken in a stuttering, stumbling way, but which cannot elude constraints whose echoes, model, style can be found, curiously enough, in contemporary mathematics.
