If, as Hegel claims, all philosophy is idealism, then defining his philosophy in these terms makes his idealism a metaphilosophy. This most obvious fact about his definition is the most overlooked. It is the key to a definitive, comprehensive and clear-cut interpretation of Hegel’s idealism. If Hegel defines all philosophy as idealism and thus his own idealism as a metaphilosophy, then his own idealism must be both the same as the old philosophies in this respect and also different in the (...) sense that it embodies self-conscious awareness. Hegel divides philosophy into pre-reflective, pre-speculative, unconscious idealism and his own reflective, speculative, thus self-conscious, absolute idealism. Missing this obvious fact is the Achilles’ heel of Stern’s non-mentalistic interpretation in the only other in-depth study of this topic, the object of this article’s critique. If Hegel’s idealism is a metaphilosophy, then it is a radical mentalistic ontology of mind and its thoughts. (shrink)
