To prove cannot mean anything other than to bring the other person to my own conviction. The truth lies only in the unification of I and You. The Other of pure thought, however, is the sensuous intellect in general. In the field of philosophy, proof therefore consists only in the fact that the contradiction between sensuous intellect and pure thought is disposed, so that thought is true not only for itself but also for its opposite.
