There is only one thing in the world that cannot be defined, and that is the idea of God. If it could be defined it would not be God, because God is greater than His name and higher than our comprehension of Him. We call Him God; if we did not call Him God then what would we call Him? But by giving a name to the nameless, by making a concept of someone who is beyond conception, we only make Him limited; at the same time, if we did not do so then we would not be doing what we ought to do. My meaning is this, that in order to respect a great man we should have some conception of what greatness is; but our conception is not of that great man as he really is, it is the idea that we have made of him. Twenty admirers of a great personality would each have his own conception of that personality.
