To the medieval thinker beauty was not a value independent of others, but rather the radiance of truth, the splendor of ontological perfection, and that quality of things which reflects their origin in God. Light and luminous objects, no less than musical consonance, conveyed an insight into the perfection of the cosmos, and a divination of the Creator.
The fairest thing we can experience is the mysterious. It is the fundamental emotion which stands at the cradle of true art and true science. A knowledge of the existence of something we cannot penetrate, of the manifestation of the profoundest reasons and the most radiant beauty, which are only accessible to our reason in their most elementary forms. It is this knowledge and this emotion that constitute the truly religious attitude; in this sense, I am a deeply religious man.
