Philosophical idealism holds a prominent place in Eastern and Western thought and comes in many, importantly distinct, varieties. There is no unique doctrine to which all idealists would subscribe, but any philosophy worthy of the name denies that reality (either as intelligible to us or in some more ultimate sense) can be adequately characterized in purely mind‐independent ways—i.e. in ways that do not recognize the fundamental and constitutive contributions of the mental or spiritual. As such, idealists reject any philosophy that is founded on the hope or assumption that reality can be adequately and exhaustively understood in entirely disenchanted, impersonal terms. This opposition is evident in all of its major variants which include subjective–ontological, transcendental, and absolute idealism.
