Note: 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. --Heyse.
