Principles of Natural Theology
Joyce, George H.
Natural Theology is that branch of philosophy which investigates what human reason unaided by revelation can tell us concerning God. The end at which it aims is to demonstrate the existence of God, to establish the principal divine attributes, to vindicate God's relation to the world as that of the Creator to the creature, and, finally, to throw what light it can on the action of divine providence in regard of man and on the problem of evil.
