"Following Kant, the most significant German philosopher was Georg Wilhelm Friedrich Hegel, whose emphasis on mind and idealism was, if anything, even greater than Kant's, as his practical influence also may have been during the nineteenth century. Hayek abhorred Hegel, considering his work virtually without value. At the same time, Hegel's emphasis on mind and idealism indicate the philosophical heritage from which Hayek sprang."
