ABSTRACT
The various sciences which deal with the interpretation of human life all avail themselves of the fundamental categories of Psychology. Hence metaphysicians must ask how the concepts of Psychology are related to actual experience. Psychology is a body of abstract descriptive formulae, not a direct transcript of the individual processes of real life. It presupposes the previous construction of the physical order. The function of Psychology is indeed quite familiar to the student of the moral and historical sciences. In Ethics, as Professor Sidgwick has observed, the whole vocabulary used to characterise human conduct, apart from the specially ethical predicates of worth, is purely psychological. If the historical appreciation of events is a legitimate human interest, the description of events in terms of end and purpose must also be a legitimate form of description. In Ethics, as Professor Sidgwick has observed, the whole vocabulary used to characterise human conduct, apart from the specially ethical predicates of worth, is purely psychological.
