PHILOSOPHICAL DICTIONARY – Psychology

Psychology. The science of the ψυχή or soul. It sometimes has been called pneumatology, but that name is by no means so happy as the one now before us.

Psychology is engaged with all the manifestations of mind, distinct from the logical process which furnishes materials for its own science logic, and from the illumination and the ideas of reason. Sensation, perception, memory, and the laws of association, all come within its province. At the end of last century, and the beginning of this, it was very commonly, but very inaccurately, called metaphysics, the name of a distinct branch of philosophy. See Metaphysics.
