Idealism, that view of the universe which, in opposition to Materialism (q.v.), refers everything to and derives everything from a spiritual root; is Subjective if traced no further back than the ego, and Objective if traced back to the non-ego likewise, its counterpart, or other, in the objective world. Idealism in art is art more or less at work in the region of the ideal in comparative disregard of the actual.
