Whoever participates in universal Knowledge will regard two apparently contradictory truths as he would two points situated on one and the same circumference that links them together by its continuity and so reduces them to unity; in the measure in which these points are distant from and thus opposed to one another there will be contradiction and this contradiction will reach its maximum when the two points are situated at the extremities of a diameter of the circle; but this extreme opposition or contradiction only appears as a result of isolating the points under consideration from the circle and ignoring the existence of the latter.
