An approach to philosophy that regards mind, spirit, or ideas as the most fundamental kinds of reality, or at least as governing our experience of the ordinary objects in the world. Idealism is opposed to materialism, naturalism, and realism. Georg Wilhelm Friedrich Hegel was an idealist; so was Immanuel Kant.
