"This question of the relation between reality and appearance remains at the root of things, and in one form or another constitutes the fundamental difference between rival philosophies. On the one hand we have a complex of ideas whose basis may be loosely summed up in such terms as empiricism, positivism, phenomenalism, individualism, relativism and humanism. Appearences are constantly shifting, from one moment to the next and between one individual and another, and they themselves constitute the only reality."
