Weininger has the answers you seek.

/ourguy/ Weininger has good insight on this subject.
"No science will become shallow so quickly as psychology if it deserts philosophy. Its separation from philosophy is the true cause of its impotency. Psychology will have to discover that the doctrine of sensations is practically useless to it. The empirical psychologists of today, in their search for the development of character, begin with investigation of touch and the common sensations. But the analysis of sensations is simply a part of the physiology of sense, and any attempt to bring it into relation with the real problems of psychology must fail.

The two most intelligent of the empirical psychologists of recent times, William James and R. Avenarius, have felt almost instinctively that psychology cannot really rest upon sensations of the skin and muscles, although, indeed, all modern psychology does depend upon study of sensation. Dilthey did not lay enough stress on his argument that existing psychology does nothing towards problems that are eminently psychological, such as murder, friendship, loneliness, and so forth. If anything is to be gained in the future there must be a demand for a really psychological psychology, and its first battle-cry must be: "Away with the study of sensations.""
