On the Unchangeableness of God (46-48)

For the mind is the sight of the soul, shining transcendently with its own rays, by which the great and dense darkness which ignorance of things sheds around is dissipated. This species of soul is not composed of the same elements as

for that is the only quality in us which the Father, who created us, thought deserving of freedom; and, unloosing the bonds of necessity, he let it go unrestrained, bestowing on it that most admirable gift and most connected with himself, the power, namely, of spontaneous will, as far as he was able to receive it; for the irrational animals, in whose soul there is not that especial gift tending to freedom, namely, mind, are put under the yoke and have bridles put in their mouths, and so are given unto men to be their slaves, as servants are given to their masters. But man, who has had bestowed on him a voluntary and self-impelling intellect, and who for the most part puts forth his energies in accordance with deliberate purpose, very properly receives blame for the offences which he designedly commits, and praise for the good actions which he intentionally performs.

For, in the case of other plants and other animals, we cannot call either the good that is caused by them deserving of praise, nor the evil that they do deserving of blame; for all their motions in either direction, and, all their changes, have no design about them, but are involuntary. But the soul of man, being the only one which has received from God the power of voluntary motion, and which in this respect has been made to resemble God, and being as far as possible emancipated from the authority of that grievous and severe mistress, necessity, may rightly be visited with reproach if she does not pay due honour to the being who has emancipated her. And therefore, in such a case, she will most deservedly suffer the implacable punishment denounced against slavish and ungrateful minds.
