If we see some admirable work of human art, we are at once eager to investigate the nature, the manner, the end of its production; and the contemplation of the works of God stirs us with an incomparably greater longing to learn the principles, the method, the purpose of creation. This desire, this passion, has without doubt been implanted in us by God. And as the eye seeks light, as our body craves food, so our mind is impressed with the . . . natural desire to know the truth of God and the causes of what we observe." --Origen(185-254)
