Jaccard finds characteristics of a new mysticism in psychoanalysis: its mode of transmission, its history punctuated with heresies, its rites of institutionalization, initiation, evidence of cultism, and a tendency to become theoretically turned in upon itself. But on the other hand, psychoanalysis resembles a science in its refusal to adhere to a Weltanschauung, in its implacable character of reductivism, in its insistence on staying close to the clinical data in order to form its theory, in the possibility of verification of conclusions, and in the progressive unmasking of illusions, even psychoanalytic illusions. This scientific status is not without a certain ambiguity, however, and the two trends, the one mystical, the other scientific, must be recognized in psychoanalysis.
