ABSTRACT
The enquiries developed in empirical research and in general theoretical elucidations under the specific guidance of the psychological gestalt-theoretical conception, in fact continually give indications of this psychophysical sub structure ; and they are, accordingly, essentially co determined by its basic character, as seen from the point of view of scientific theory. The purely psychologically founded gestalt concept, too, always involves what seems to have been ascertained “ from the starting point of physics ” about the definiteness and certainty of the gestalt tenets.
