ABSTRACT
Psychical actions and reactions are, like every event known to necessary occurrences; that is to say, they result with compulsory regularity from their conditions and causes. If would compare psychical processes with some group of external phenomena, the physical and a narrower sense mechanical processes are Jess suitable than the functions of the organism. This statement is confirmed by the fact that so-called empirical utility is found in the psychical functions as well as in the organic functions of the bodily sphere. The appropriateness that observe in growth, in propagation and regeneration, in adaptation to environment, in healing, and so on, in the sphere of the organic repeats itself in the psychical processes. The psychical organisi also reacts fittingly to stimuli. Most stress on the practical corroboration, on the experimental test of the utility of the logical structures that are the product of the organic function of thought.
