To pit this single assertion, that “in the Absolute all is one”, against the organized whole of determinate and complete knowledge, or of knowledge which at least aims at and demands complete development—to give out its Absolute as the night in which, as we say, all cows are black—that is the very naïveté of emptiness of knowledge.

(Hegel, tr. Baillie, The Phenomenology of Mind, Preface)
