The theologian considers sin mainly as an offence against God; the moral philosopher as contrary to reasonableness.

What can be accomplished by a few principles is not effected by many. But it seems that everything we see in the world can be accounted for by other principles, supposing God did not exist. For all natural things can be reduced to one principle, which is nature, and all voluntary things can be reduced to one principle, which is human reason, or will. Therefore there is no need to suppose God's existence.

Love takes up where knowledge leaves off.

Human salvation demands the divine disclosure of truths surpassing reason.

The test of the artist does not lie in the will with which he goes to work, but in the excellence of the work he produces.

If the highest aim of a captain were to preserve his ship, he would keep it in port forever.

Future contingents cannot be certain to us, because we know them as such. They can be certain only to God whose understanding is in eternity above time. Just as a man going along a road does not see those who come after him; but the man who sees the whole road from a height sees all those who are going along the road at the same time.
