The question regarding psychology and its scientific legitimacy is approached from the point of view of kantian epistemology. In spite of denying psychology scientific legitimacy, Kant placed the object of psychology within the field of experience, the phenomena of internal sense, paving the road for the experimental psychology of the nineteenth century. But it's in Kant´s "Anthropology from the Pragmatic Point of View" that we find an orientation for psychology. Instead of the empirical subject in his passivity, understood as interiority, psychology would consider the subject as activity which is incarnated in the external world, defining the existence of man through his conduct in history.
