"Hegel's principal achievement is his development of a distinctive articulation of idealism sometimes termed "absolute idealism,"[8] in which the dualisms of, for instance, mind and nature and subject and object are overcome.

"He started Hegelianism and is a part of German Idealism. He influenced many writers and philosophers, including those who agreed with him (Bradley, Sartre, Küng, Bauer, Stirner, Marx), and those who did not agree with him (Kierkegaard, Schopenhauer, Nietzsche, Heidegger, Schelling). Hegel's books are difficult to read and deal with many different ideas at the same time. He has written about history, politics, religion, art, logic and metaphysics."
