That we all depend in every detail, at every instant, as a Christian would say upon God, as even an agnostic would say upon existence and the nature of things, is not an illusion of imagination; on the contrary, it is the fundamental fact which we cover up, as with curtains, with the illusion of ordinary life. That ordinary life is an admirable thing in itself, just as imagination is an admirable thing in itself. But it is much more the ordinary life that is made of imagination than the contemplative life. He who has seen the whole world hanging on a hair of the mercy of God has seen the truth; we might almost say the cold truth. He who has seen the vision of this city upside-down has seen it the right way up.
