"The theologian considers sin mainly as an offence against God; the moral philosopher as contrary to ..." — Thomas Aquinas

Moral science is better occupied when treating of friendship than of justice.

Distinctions drawn by the mind are not necessarily equivalent to distinctions in reality.

Reason in man is rather like God in the world.

It is possible to demonstrate God's existence, although not a priori, yet a posteriori from some work of His more surely known to us.
