Abstract

The aim of this work is to show how a psychoanalysis may be formalized starting from the six modal categories and the laws that regulate their relations in the sphere of reality identified by Nicolai Hartmann in Possibility and Actuality. Frequently, Lacan uses Aristotelian modal categories – contingency, necessity, impossibility, possibility – to describe both psychic life and the psychoanalytic work. And yet, in our opinion, their revision proposed by Hartmann – actuality, non-actuality, possibility, necessity, contingency – better serves the goals pursued by the French psychoanalyst.
