There is, I know not how, a certain presage, as it were, of a future existence; and this takes the deepest root, and is most discoverable, in the greatest geniuses and most exalted souls.
A wise unselfishness is not a surrender of yourself to the wishes of anyone, but only to the best discoverable course of action.
God is not discoverable or demonstrable by purely scientific means, unfortunately for the scientifically minded. But that really proves nothing. It simply means that the wrong instruments are being used for the job.
