Psychophysics synonyms

In philosophy he began with a strong predilection for the physical side of psychology, and at an early age he came to the conclusion that all existence is sensation, and, after a lapse into noiimenalism under the influence of Fechner's Psychophysics, finally adopted a universal physical phenomenalism.

It becomes necessary, therefore, to determine how far Fechner derived his psychophysics from experience, how far from fallacies of inference, from his romantic imagination and from his theosophic metaphysics, which indeed coloured his whole book on psychophysics.

By his psychophysics he meant the exact doctrine of the relations of dependency between physical and psychical.

Having satisfied himself in what he called " outer psychophysics," that the stimulus causes only the nervous process and not sensation, he passed to what he called " inner psychophysics," or the theory of the relation between nervous and psychical processes.

Fechner first confused physics and metaphysics in psychophysics, and next proceeded to confuse them again in his work on evolution (Einige Ideen zur SchOpfungs and Entwicklungs-geschichte der Organismen, 1873).
