...Consider this then: That there is a level of truth, vitally important to human beings, which lies beyond the explainable, demonstrable natural world. In fact, this truth is often more important and sustaining to human beings because it is an eternal truth, not changeable, never at the mercy of different historical theories, or the whims of the scientist, or the observer of heavenly bodies. This truth, in a sense, is our spiritual food.
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.
