There is probably another sense, however, in which psychology comes into close relation with ethics. If we look on man as a microcosm, his inner system will more or less reproduce the system of the larger world. The older psychology used to distinguish an upper or superior order of faculties from a lower or inferior. Thus in the intellectual sphere, the intellect, judgment, and reason were set above the senses, imagination, and memory. Among the active powers, reasonable will, practical reason and conscience were ranked as paramount over the appetites and desires and emotions. And this use of the word “faculty” is as old as Plato, who regards science as a superior faculty to opinion or imagination. But this application—which seems a perfectly legitimate one—does not, in the first instance, belong to psychology at all. No doubt it is psychically presented: but it has an other source. It springs from an appreciation, a judgment of the comparative truth or reality of what the so-called psychical act means or expresses. Such faculties are powers in a hierarchy of means and ends and presuppose a normative or critical function which has classified reality. Psychically, the elements which enter into knowledge are not other than those which belong to opinion: but they are nearer an adequate rendering of reality, they are truer, or nearer the Idea. And in the main we may say, that is truer or more real which succeeds in more completely organising and unifying elements—which rises more and more above the selfish or isolated part into the thorough unity of all parts.
