Today, much of psychoanalysis has moved beyond Freud, both methodologically and theoretically. I understand Freud to have been always either explicitly or implicitly committed to the view that psychoanalysis is a science, if only at times as an aspirational goal. The question I intend to raise in this article is not whether psychoanalysis is scientific, but rather whether it should still consider itself so in the light of contemporary theoretical physics' ever greater dependence on mathematical assertions that have not to date been validated by experimental conformation. Bestowing the appellation of science to superstring theory, “the theory of everything,” is at present a self-crowing by its adherents taken as a hereditary birthright. I view the relation between psychoanalytic theory and contemporary theoretical physics as a parallelism – a parallelism between approaches to conceptualisation rather than a reduction of disciplines.
