ABSTRACT

The test of any theory is the completeness with which it explains known facts. The presentation of the facts of mental processes as set forth in the preceding chapters is in some respects different from that usually found. We have been led to this point of view by the study of the feeble-minded; and have been confirmed in these views by the wide application they seem to have, not only to the feeble-minded but to many common phenomena of life. We shall attempt in the following chapters to point out some of these applications.
