Reacting against the constitutionalist tendency of the late nineteenth century, Freud insisted that the individual factor be taken into account through psychoanalysis. He substituted for a phylogenetic theory the ontogenetic perspective. It will be seen that the black man's alienation is not an individual question. Beside phylogeny and ontogeny stands sociogeny. In one sense, conforming to the view of Leconte and Damey, let us say that this is a question of a sociodiagnostic.
