Quote from : Philosophic Nights in Paris,: Being Selections from Promenades Philosophiques Book

It is undefinable; and moreover, if it were defined it would lose all its value. God is not all that exists; God is all that does not exist. Therein resides the power & the charm of that mysterious word. God is tradition, God is legend, God is folklore, God is a fairy-tale, God is romance, God is a lie, God is a bell, God is a church window, God is religion, God is all that is absurd, useless, invisible, intangible, all that is nothingness & that symbolizes nothingness. God is the nihil in tenebris-(nothing in the darkness) -men have made of him light, life & love.
