Psychoanalysis is the name of a practical psychology, which seeks to make intelligible the aberrant phenomena in the stream of human experience which often are coincident with suffering and ineffectuality. In addition, it has another distinguishing characteristic in that it seeks to create a teachable method for the systematic treatment of these disturbances in adaptation. The application of scientific method to a psychology with these objectives created problems which are unique. These problems stem from the nature of the subject matter with which it deals and the particular objectives of the scientific maneuvers. Its subject matter constitutes material which no other psychology has seen fit to deal with and the objective, namely, therapy, is one which imposes upon this scientific discipline a social responsibility.
