While scientists were performing astounding feats of disciplined reason [during the Enlightenment], breaking down the barriers of the “unknowable” in every field of knowledge, charting the course of light rays in space or the course of blood in the capillaries of man's body -- what philosophy was offering them, as interpretation of and guidance for their achievements was the plain Witchdoctory of Hegel, who proclaimed that matter does not exist at all, that everything is Idea (not somebody's idea, just Idea), and that this Idea operates by the dialectical process of a new “super-logic” which proves that contradictions are the law of reality, that A is non-A, and that omniscience about the physical universe (including electricity, gravitation, the solar system, etc.) is to be derived, not from the observation of facts, but from the contemplation of that Idea's triple somersaults inside his, Hegel's, mind. This was offered as a philosophy of reason.
