This article presents observations for a discussion on the research method in psychoanalysis. Between psychoanalysis and science there is a relationship of logical compatibility that refers to the use of a qualification that disqualifies the usual meaning of the concepts, thus producing a new concept by means of articulations that were previously impossible. This paper is called by the historical epistemology of qualification, disqualifying, and for Lacan, subversion. The articulation of these two concepts certifies the compatibility between the way of researching in science and in psychoanalysis.
