CHAPTER IX. Definitions of Psychology

DEFINITIONS OF PSYCHOLOGY

Difficulty of defining psychology--Definition by substance--Psychology not the science of the soul--Definition by enumeration: its error--Definition by method contradicts idea of consciousness--Externospection and introspection sometimes confused--Definition by content--Facts cannot be divided into those of consciousness and of unconsciousness--Descartes' definition of psychology insufficient--"Within and without" simile unanalogous--Definition by point of view--Inconsistencies of Ebbinghaus' contention--W. James' teleological theory--Definition by the peculiar nature of mental laws only one possible: why?
