The light of faith makes us see what we believe.

The Study of philosophy is not that we may know what men have thought, but what the truth of things is.

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.

Man should not consider his material possession his own, but as common to all, so as to share them without hesitation when others are in need.

Sloth is sluggishness of the mind which neglects to begin good...it is evil in its effect, if it so oppresses man as to draw him away entirely from good deeds.

God himself would not permit evil in this world if good did not come of it for the benefit and harmony of the universe.

If you can live amid injustice without anger, you are immoral as well as unjust.
