John Dewey,
Psychology and Social Practice
“ It is not merely incidentally, as a grateful addition to its normal task, that psychology serves us. The essential nature of the standpoint which calls it into existence, and of the abstraction which it performs, is to put in our possession the method by which values are introduced and effected in life. The statement of personality as an object, of social relations as a mechanism of stimuli and inhibitions, is precisely the statement of ends in terms of the method of their realization. ”
