☞ This term was formerly used to express the same idea as psychological. Recent metaphysicians, however, have employed it to mark the difference between psychh` the living principle in man, and pney^ma the rational or spiritual part of his nature. In this use, the word describes the human soul in its relation to sense, appetite, and the outer visible world, as distinguished from spiritual or rational faculties, which have to do with the supersensible world.
