Are rationalism and idealism compatible?
Idealism is the belief in mind over matter; the conviction that matter itself has no existence apart from mind (one-directional). "Objects" and "matter" exist only in being perceived. However, several of the most prominent idealist philosophers, such as Socrates, Plato, Berkeley, Hume, Kant and Schopenhauer, are also classified as rationalists. Is this possible? Or is it a fundamental contradiction?
