Idealists are high-energy achievers who believe in the positive potential of everyone around them. They want to learn and grow, and they want everyone else. a person who cherishes or pursues high or noble principles, purposes, goals, etc. a visionary or impractical person; a person who represents things as they. Fichte, Schelling, and Hegel radicalized this view, transforming Kant's transcendental idealism into absolute idealism, which holds that things in themselves.
