ABSTRACT
Karl Buhler's researches and the subsequent expositions are mutually complementary. Buhler lays especial emphasis on the premises of general psychology which aim at the explanation of primitive thought; he examines theoretically the facts of the certainty of remembrance, of the grasp of facts and their bearing to each other, of the conditions of the processes of judgment, formation of ideas and the drawing of conclusions, in order subsequently to prepare a systematic psychology of thought in childhood. Psychological theory must distinguish thought from conception in two ways: in difference of content and difference of process. The conscious activity is only repetition of former conscious processes, it is not thought, but only perceptual reproduction, hence it happens that psychic processes may assume the logical form of acts of thought in their expression without being such psychologically. As regards quality, the child's earliest judgments are all of a positive nature; they state a condition of things that attracts the child's attention.
