" A man deeply concerned in an affair of great importance, that should take up all the attention of his mind, might pass several days in a room treating about his concerns without taking notice of the proportions of the chamber, the ornaments of the chimney, and the pictures about him, all which objects would continually be before his eyes, and yet none of them make any impression upon him.  In this manner it is that men spend their lives; everything offers God to their sight, and yet they see it nowhere.  “He was in the world, and the world was made by Him, and nevertheless the world did not know Him "

― François Fénelon , The Existence of God
