The general psychological concept of Eugen Bleulers later studies - An attempt to depict a forgotten theory 60 years after the final publication

Documents by Eugen Bleuler from 1921 to 1939 that go into general psycholog ical topics of meaning of consciousness, formation of motive and will, are presented. An effort towards integration of seemingly incompatible, side by side standing, unrelated biological and psychological concepts that probab ly is most likeley explainable by the contemporary background of ideas, is recognizable. In this context, Eugen Bleuler refers to an already (especial ly by Richard Semen) systematically developed theory called "Mnemism" that he interpreted and applied to the psychological circumstances mentioned abo ve. That theory of "mnemism" that can be most adaequately described as a bi ogenetic-vitalistic theory, is assuming, that all organic life - independen t of the possibility of a self-reflecting consciousness - is able to learn experiences made by analysis of environment and to pass it on following gen erations. Pattern of stimulus reactions are in the sense of this theory mem orized ("engraphiert") and reactivated under similar situational circumstan ces ("ekphoriert") by the psychological mode of association. - It can be sh own that Bleuler pursued this theory for a period of more than ten years. I t represents the benchmark for Bleuler's standpoints, for example for the q uestion of determination of human acting, that as itselves are already know n from his earlier documents, but here have found a more theoretically base d explanation. The assumption of the efficacy of specific, not necessary co nsciously remembered "engramms" of memory, suggests the hypothesis of the e xistence of unconsciousness; in this context textual points of contact to t he psychological concepts of S. Freud and C. G. lung - mnemic memory and co llective unconscious - are shown.
