When Hillary Clinton ran against Senator [Barack] Obama she thought him naive because he thought it was a good idea to talk to our enemies. I think those are exactly the people you have to talk to and you have to negotiate with.
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.
