個性動力論（簡體書）

Galileian Ooncept Formation.
Opposed to Aristotelian concept formation, which I have sought briefly to characterize, there is now evident in psychology a development which appears occasionally in radieal or apparently radical tendencies,more usually in little half steps, sometimes fall- ing into error (especially when it tries most exactly to follow the example of physics), but which on the whole seems clearly and ir- resistibly to be pushing on to modifications that may ultimately mean nothing less than a transition from Aristotelian to Galileian concept formation.
No Value Concepts.No Dichotomies.Unification of Fields.The most important general circumstances which paved the way for Galileian concepts in physics are clearly and distinctly to be seen in present-day psychology.
The conquest over valuative,anthropomorphic classifications of phenomena on bases other than the nature of the mental process itself (see page 3) is not by any means complete, but in many fields, especially in sensory psychology, at least the chief difficulties are past.
As in physics,the grouping of events and objects into paired opposites and similar logical dichotomies is being replaced by groupings with the aid of serial concepts which permit of continu- ous variation, partly owing simply to wider experience and the rec- ognition that transition stages are always present.
This has gone furthest in sensory psychology, especially in psychological optics and acoustics, and lately also in the domain of smell.
