SummaryIn this article I was guided outside my special branch of science, by coincidences of the sense of the ideas occuring almost simultaneously in different sciences : correspondence, complementary pairs of opposites and wholeness appear independently both in physics as well as in the ideas of the unconscious. The unconscious t itself has a certain analogy to the field in physics and both are shifted by an observational problem, outside the range of visualibility into the paradoxical. Although in physics one (...) does not speak of archetypes which reproduce themselves, but of statistical laws of nature with primary probabilities, both formulations meet in the tendency to amplify the older more narrow idea of causality to a more general form of connections in nature, toward which the psycho‐physical problem also points. This way of consideration leads me to the expectation, that the ideas on the unconscious will not be developed further in the narrow frame of its therapeutic applications, but that their junction with the general stream of the natural sciences of the phenomena of life will be decisive for them.
