The coincidance of their contraries

Nicolas of Cusa's ("Micholas de Cusack") philosophy of the coincidence of opposites.

We arrive at the knowledge of the reality (God), and hence of unity and the infinite, only by means of a third activity of the spirit, the faculty of intellect, which is supra-rational understanding, mystical intuition. This faculty, overcoming all differences and multiplicity, presents the reality (God) as perfect unity, in which all differences are reconciled in the infinite life, the "coincidence of opposites." The principle of coincidence is for Nicholas of Cusa a new one on which logic must be based in order to arrive at the knowledge of reality.
