This from Gareth Stedman Jones's introduction to The Communist Manifest (Penguin Classics):
Like Feuerbach, Marx's aim was wholly to remove Hegel's mediations and return to immediacy. According to Feuerbach, the great defect of Hegel's philosophy was that it lacked 'immediate unity, immediate certainty, immediate truth'. In place of Hegel's process of bifurcation, mediation and reunion, what was needed was a philosophy of man as an immediate whole.
This notion of immediacy is utterly incomprehensive to me! To me, every unity, certainty, or truth need mediation of some kind. Man is incapable of grasping such without mediation. Hard to say, but in this respect Hegel seems to be right.
