"The immense energy Nicholas constantly poured into church reform at every level never obscured his philosophical clarity nor his subtle mysticism. For him, consciousness should ever seek Divine Unity, whilst action should have fraternal harmony as its purpose. The church, according to Nicholas, is a living unity, a fraternity united to the divine presence symbolized in Christ. As Deity is simple and also light, the shadows and reflections which constitute the world catch and transmit the light only to the degree that they form a universal harmony, the primary reflection of Divine Unity. Since Divine Light is simple and therefore the referent of only one Word, language and the categories of thought are necessarily engendered from experience of the realm of shadows...Opposites suggest new levels of synthesis; Deity is the coincidentia oppositorum, the reconciliation of contraries. Thus Nicholas, who taught that knowledge in one sense is conjecture, held that a careful examination of Nature and human thought reveals contraries and contradictions that can guide one to ever greater understanding. He found time to study Islam in detail, to propose a method of squaring any circle, to argue for the rotation of the earth on its axis, and to propose that the universe is boundless in time and space. Harmony is understood, he professed, and unity achieved by loving each and every thing according to its place in the community of Nature...Drawing from Pythagoras, Dionysius the Areopagite, and Meister Eckhart, Nicholas of Cusa kept alive the mystic flame of intuition and passed it to individuals as different as Giordano Bruno and Copernicus. Whilst struggling for moral reform within a decaying structure, he subtly laid the foundation of human dignity upon which both the Renaissance and the Reformation would be built."
