Values as constraints on affordances: Perceiving and acting properly

Abstract

At the bottom of all human activities are “values,” the conviction that some things “ought to be” and others not. Science, however, with its immense interest in mere facts seems to lack all understanding of such‘requiredness.’… A science … which would seriously admit nothing but indifferent facts … could not fail to destroy itself. (Kohler, 1938/1966, p. 38‐39)
