We know that there is an infinite, and we know not its nature. As we know it to be false that numbers are finite, it is therefore true that there is a numerical infinity. But we know not of what kind; it is untrue that it is even, untrue that it is odd; for the addition of a unit does not change its nature; yet it is a number, and every number is odd or even (this certainly holds of every finite number). Thus we may quite well know that there is a God without knowing what He is.
Blaise PascalWhen we would think of God, how many things we find which turn us away from Him, and tempt us to think otherwise. All this is evil, yet it is innate.
Blaise PascalOur imagination so magnifies this present existence, by the power of continual reflection on it, and so attenuates eternity, by not thinking of it at all, that we reduce an eternity to nothingness, and expand a mere nothing to an eternity; and this habit is so inveterately rooted in us that all the force of reason cannot induce us to lay it aside.
Blaise Pascal
