Note 146 — LECTURE IX THE ORGANIZATION OF UNCONSCIOUS COMPLEXES

Zeitschrift für Psychotherapie und Medizinishe Psychologie, Bd. 11, Hft. 3, 1910.) An example is the well-known psychological diagram which may be perceived at one moment as a flight of steps and at another as an overhanging wall, according as which perception of the same line is switched in.
