Chap. XI.—Of the Last Times, and of the Soul and Body.
Therefore, when the times which God has appointed for death shall be completed, death itself shall be ended. And because temporal death follows temporal life, it follows that souls rise again to everlasting life, because temporal death has received an end. Again, as the life of the soul is everlasting, in which it receives the divine and unspeakable fruits of its immortality; also its death must be eternal, in which it suffers perpetual punishments and infinite torments for its faults. Therefore things are in this position, that they who are happy in this life, pertaining to the body and the earth, are about to be miserable for ever, because they have already enjoyed the good things which they preferred, which happens to those who adore false gods and neglect the true God. In the next place, they who, following righteousness, have been miserable, and despised, and poor in this life, and have often been harassed with insults and injuries on account of righteousness itself, because virtue cannot otherwise be attained, are about to be always happy, that since they have already endured evils, they may also enjoy goods. Which plainly happens to those who, having despised gods of the earth and frail goods, follow the heavenly religion of God, whose goods are everlasting, as He Himself who gave them. What shall I say of the works of the body and soul? Do not they show that the soul is not subject to death? For, as to the body, since it is itself frail and mortal, whatever works it contrives are equally perishable. For Tullius says that there is nothing which is wrought by the hands of man which is not at some time reduced to destruction, either through injury caused by men, or through length of time, which is the destroyer of all things.
But truly we see that the productions of the mind are immortal. For as many as, devoting themselves to the contempt of present things, have handed down to memory the monuments of their genius and great deeds, have plainly gained by these an imperishable name for their mind and virtue. Therefore, if the deeds of the body are mortal for this reason, because the body itself is mortal, it follows that the soul is shown to be immortal from this, because we see that its productions are not mortal. In the same manner also, the desires of the body and of the soul declare that the one is mortal, the other everlasting. For the body desires nothing except what is temporal, that is, food, drink, clothing, rest, and pleasure; and it cannot desire or attain to these very things without the assent and assistance[1] of the soul. But the soul of itself desires many things which do not extend[2] to the duty or enjoyment of the body; and those are not frail, but eternal, as the fame of virtue, as the remembrance of the name. For the soul even in opposition to the body desires the worship of God, which consists in abstinence from desires and lusts, in the enduring of pain, in the contempt of death. From which it is credible that the soul does not perish, but is separated from the body, because the body can do nothing without the soul, but the soul can do many and great things without the body. Why should I mention that those things which are visible to the eyes, and capable of being touched by the hand, cannot be eternal, because they admit of external violence; but those things which neither come under the touch nor under the sight, but are apparent only in their force and method and effect, are eternal because they suffer no violence from without? But if the body is mortal on this account, because it is equally open to the sight and to the touch, therefore the soul is immortal for this reason, because it can be neither touched nor seen.
