The Divine Institutes

But our inquiry is as to the object for which we are born: and thus we are able to trace out what is the effect of virtue. There are two parts of which man is made up, soul and body. There are many things peculiar to the soul, many peculiar to the body, many common to both, as is virtue itself; and as often as this is referred to the body, it is called fortitude for the sake of distinction. Since, therefore, fortitude is connected with each, a contest is proposed to each, and victory held forth to each from the contest: the body, because it is solid, and capable of being grasped, must contend with objects which are solid and can be grasped; but the soul, on the other hand, because it is slight and subtle, and invisible, contends with those enemies who cannot be seen and touched. But what are the enemies of the soul, but lusts, vices, and sins? And if virtue shall have overcome and put to flight these, the soul will be pure and free from stain. Whence, then, are we able to collect what are the effects of fortitude of soul? Doubtless from that which is closely connected with it, and resembles it, that is, from fortitude of the body; for when this has come to any encounter and contest, what else does it seek from victory but life? For whether you contend with a man or beast, the contest is for safety. Therefore, as the body obtains by victory its preservation from destruction, so the soul obtains a continuation of its existence; and as the body, when overcome by its enemies, suffers death, so the soul, when overpowered by vices, must die. What difference, therefore, will there be between the contest carried on by the soul and that carried on by the body, except that the body seeks for temporal, but the soul eternal life? If, therefore, virtue is not happy by itself, since its whole force consists, as I have said, in the enduring of evils; if it neglects all things which are desired as goods; if in its highest condition it is exposed to death, inasmuch as it often refuses life, which is desired by others, and bravely undergoes death, which others fear; if it must necessarily produce some great good from itself, because labours, endured and overcome even until death, cannot fail of obtaining a reward; if no reward, such as it deserves, is found on earth, inasmuch as it despises all things which are frail and transitory, what else remains but that it may effect some heavenly reward, since it treats with contempt all earthly things, and may aim at higher things, since it despises things that are humble? And this reward can be nothing else but immortality.

With good reason, therefore, did Euclid, no obscure philosopher, who was the founder of the system of the Megareans, differing from the others, say that that was the chief good which was unvarying and always the same. He certainly understood what is the nature of the chief good, although he did not explain in what it consisted; but it consists of immortality, nor anything else at all, inasmuch as it alone is incapable of diminution, or increase, or change. Seneca also unconsciously happened to confess that there is no other reward of virtue than immortality. For in praising virtue in the treatise which he wrote on the subject of premature death, he says: “Virtue is the only thing which can confer upon us immortality, and make us equal to the gods.” But the Stoics also, whom he followed, say that no one can be made happy without virtue. Therefore, the reward of virtue is a happy life, if virtue, as it is rightly said, makes a happy life. Virtue, therefore, is not, as they say, to be sought on its own account, but on account of a happy life, which necessarily follows virtue. And this argument might have taught them in what the chief good consisted. But this present and corporeal life cannot be happy, because it is subjected to evils through the body. Epicurus calls God happy and incorruptible, because He is everlasting. For a state of happiness ought to be perfect, so that there may be nothing which can harass, or lessen, or change it. Nor can anything be judged happy in other respects, unless it be incorruptible. But nothing is incorruptible but that which is immortal. Immortality therefore is alone happy, because it can neither be corrupted nor destroyed. But if virtue falls within the power of man, which no one can deny, happiness also belongs to him. For it is impossible for a man to be wretched who is endued with virtue. If happiness falls within his power, then immortality, which is possessed of the attribute of happiness, also belongs to him.

The chief good, therefore, is found to be immortality alone, which pertains to no other animal or body; nor can it happen to any one without the virtue of knowledge, that is, without the knowledge of God and justice. And how true and right is the seeking for this, the very desire of this life shows: for although it be but temporary, and most full of labour, yet it is sought and desired by all; for both old men and boys, kings and those of the lowest station, in fine, wise as well as foolish, desire this. Of such value, as it seemed to Anaxagoras, is the contemplation of the heaven and the light itself, that men willingly undergo any miseries on this account. Since, therefore, this short and laborious life, by the general consent not only of men, but also of other animals, is considered a great good, it is manifest that it becomes also a very great and perfect good if it is without an end and free from all evil. In short, there never would have been any one who would despise this life, however short it is, or undergo death, unless through the hope of a longer life. For those who voluntarily offered themselves to death for the safety of their countrymen, as Menœceus did at Thebes, Codrus at Athens, Curtius and the two Mures at Rome, would never have preferred death to the advantages of life, unless they had thought that they should attain to immortality through the estimation of their countrymen; and although they were ignorant of the life of immortality, yet the reality itself did not escape their notice. For if virtue despises opulence and riches because they are frail, and pleasures because they are of brief continuance, it therefore despises a life which is frail and brief, that it may obtain one which is substantial and lasting. Therefore reflection itself, advancing by regular order, and weighing everything, leads us to that excellent and surpassing good, on account of which we are born. And if philosophers had thus acted, if they had not preferred obstinately to maintain that which they had once apprehended, they would undoubtedly have arrived at this truth, as I have lately shown. And if this was not the part of those who extinguish the heavenly souls together with the body, yet those who discuss the immortality of the soul ought to have understood that virtue is set before us on this account, that, lusts having been subdued, and the desire of earthly things overcome, our souls, pure and victorious, may return to God, that is, to their original source. For it is on this account that we alone of living creatures are raised to the sight of the heaven, that we may believe that our chief good is in the highest place. Therefore we alone receive religion, that we may know from this source that the spirit of man is not mortal, since it longs for and acknowledges God, who is immortal.
