It is possible, also, that if his philosophy had been less exclusively moral, if it had implied a more curious study of history and of the universe, it would have escaped a certain excessive rigor. Like the ascetic Christians, Marcus Aurelius sometimes carried renunciation to dryness and subtlety. One feels that this calmness, which never belies itself, is obtained through an immense effort. Certainly, evil had never an attraction for him: he had no passion to struggle against. "Whatever one may do or say," writes he, "it is necessary that I should be a good man; as the emerald might say, 'Whatever one may say or do, I must remain an emerald, and retain my color.'" But, in order to hold one's self always upon the icy summit of stoicism, it is necessary to do cruel violence to nature, and to cut away from it more than one noble element. This perpetual repetition of the same reasoning, the thousand figures under which he seeks to represent to himself the vanity of all things, these frequently artless proofs of universal frivolity, testify to strifes which he has passed through in order to extinguish all desire in himself. At times we find in it something harsh and sad. The reading of Marcus Aurelius strengthens, but it does not console: it leaves a void in the soul which is at once cruel and delightful, which one would not exchange for full satisfaction. Humility, renunciation, severity towards self, were never carried further. Glory—that last illusion of great souls—is reduced to nothingness. It is needful to do right without disturbing one's self as to whether any one knows that we do it. He perceives that history will speak of him: he sometimes dreams of the men of the past with whom the future will associate him. "If they have only played the part of tragic actors," said he, "no one has condemned me to imitate them." The absolute mortification at which he had arrived had destroyed the last fibre of self-love in him.

The consequences of this austere philosophy might have been hardness and obstinacy. It is here that the rare goodness of the nature of Marcus Aurelius shines out in its full brilliancy. His severity is only for himself. The fruit of this great tension of soul is an infinite benevolence. All his life was a study of how to return good for evil. At evening, after some sad experience of human perversity, he wrote only as follows: "If thou canst, correct them; on the other hand, remember that thou shouldest exercise benevolence towards those who have been given to thee. The gods themselves are benevolent to men: they aid them,—so great is their goodness!—to acquire health, riches, glory. Thou art permitted to be like the gods." Another day, some one was very wicked; for see what he wrote upon his tablets: "Such is the order of nature: men of this sort must act thus from necessity. To wish it to be otherwise is to wish that the fig-tree shall bear no figs. Remember, thou, in one word, this thing: in a very short time thou and he will die; soon after, your names even will be known no more." The thoughts of a universal pardon recur without ceasing. At times a scarcely perceptible smile is mingled with this charming goodness,—"The best method of avenging one's self upon the wicked is not to be like them;" or a light stroke of pride,—"It is a royal thing to hear evil said of one's self when one does right." One day he thus reproached himself: "Thou hast forgotten," said he, "what holy relationship unites each man to the human race,—a relationship not of blood, or of birth, but the participation in the same intelligence. Thou hast forgotten that the reasoning power of each one is a god, derived from the Supreme Being."

In the business of life he was always exact, although a little ingenuous, as very good men usually are. The nine reasons for forbearance which he valued for himself (book xi. art. 18) show us his charming good-nature before family troubles, which perhaps came to him through his unworthy son. "If, upon occasion," said he to himself, "thou exhortest him quietly, and shalt give to him without anger some lessons like these,—'No, my child; we are born for each other. It is not I who suffer the evil, it is thou who doest it thyself, my child!'—show him adroitly, by a general consideration, that such is the rule; that neither the bees, nor the animals who live naturally in herds, resemble him. Say this without mockery or insult, with an air of true affection, with a heart which is not excited by anger; not as a pedant, not for the sake of being admired by those who are present; think only of him."

Commodus (if it was for him that he thus acted) was, without doubt, little touched by this good paternal rhetoric. One of the maxims of the excellent emperor was, that the wicked are unhappy, that one is only wicked in spite of himself, and through ignorance. He pitied those who were not like himself: he did not believe that he had the right to obtrude himself upon them.

He well understood the baseness of men; but he did not avow it. This willing blindness is the defect of choice spirits. The world not being all that they could wish, they lie to themselves in order not to see it as it is. From thence arises an expediency in their judgments. In Marcus Aurelius, this expediency sometimes provokes us a little. If we wished to believe him, his instructors, several of whom were men of mediocrity, were, without exception, superior men. One would say that every one near him had been virtuous. This is carried to such a point, that one is forced to ask if the brother for whom he pronounces such a grand eulogy in his thanks to the gods was not his adopted brother, Lucius Verus. It is certain that the good emperor was capable of strong illusions when he undertook to lend to others his own virtues.

This quality, expressed as an ancient opinion, especially by the pen of the Emperor Julian, caused him to commit an enormous error, which was that of not disinheriting Commodus. This is one of those things which it is easy to say at a distance, when there are no obstacles present, and when one reasons without facts. It is forgotten at first that the emperors, who, after Nerva, made adoption so fruitful a political system, had no sons. Adoption, with the exheredation of the son or grandson, occurred in the first century of the empire without good results. Marcus Aurelius was evidently from principle in favor of direct inheritance, in which he saw the advantage of the prevention of competition.

After the birth of Commodus, in 161, he presented him alone to the people, although he had a twin-brother: he frequently took him in his arms and renewed this act, which was a sort of proclamation. In 166 Lucius Verus demanded that the two sons of Marcus, Commodus and Annius Verus, should be made Cæsars. In 172 Commodus shared with his father the title of Germanicus. In 173, after the repression of the revolt of Avidius, the Senate, in order to recognize in some way the family disinterestedness which Marcus Aurelius had shown, demanded by acclamation the empire and the tribunitial power for Commodus.

Already the natural wickedness of the latter had betrayed itself by more than one symptom known to his tutors; but how shall one foresee the future from a few naughty acts of a child of twelve years? In 176-177 his father made him Imperator, Consul, Augustus. This was certainly an imprudence; but he was bound by his previous acts: Commodus, moreover, still restrained himself. In later years, the evil completely revealed itself. On each page of the last books of the "Thoughts," we see the trace of the martyr within the excellent father, of the accomplished emperor, who saw a monster growing up beside him, ready to succeed him, and to take in every thing through antipathy, the opposite course from that which he had believed to be for the good of men. The thought of disinheriting Commodus must, without doubt, have come often to Marcus Aurelius. But it was too late. After having associated him in the empire, after having so many times proclaimed him to the legions as perfect and accomplished, to come before the world and declare him to be unworthy would be a scandal. Marcus was caught in his own phrases, by that style of benevolent expediency which was too habitual with him. And, after all, Commodus was only seventeen years old: who could be sure that he would not reform? Even after the death of Marcus Aurelius this was hoped for. Commodus at first showed the intention of following the counsels of meritorious persons with whom his father had surrounded him.

The reproach which is made, then, against Marcus Aurelius, is not that of not having, but of having, a son. It was not his fault if the age could not support so much wisdom. In philosophy, the great emperor had placed the ideal of virtue so high, that no one would care to follow him. In politics, his benevolent optimism had enfeebled the state services, above all, the army. In religion, in order not to be too much bound by a religion of the state, of which he saw the weakness, he prepared the great triumph of the non-official worship, and left a reproach to hover above his memory,—unjust, it is true; but even its shadow should not be found in so pure a life. We touch here upon one of the most delicate points in the biography of Marcus Aurelius. It is unhappily certain, that, under his reign, Christians were condemned to death, and executed. The policy of his predecessors had been firm in this particular. Trajan, Antonine, Hadrian himself, saw in the Christians a secret sect, anti-social, dreaming of overturning the empire. Like all men true to the old Roman principles, they believed in the necessity of repressing them. There was no need of special edicts: the laws against the cœtus illiciti, the illicita collegia, were numerous. The Christians fell in the most explicit sense under the force of these laws. Truly, it would have been worthy of the wise emperor who introduced so many reforms full of humanity, to suppress the edicts which entailed such cruel and unjust consequences. But it is necessary to observe primarily, that the true spirit of liberty, as we understand it, was not then understood by any one; and that Christianity, when it was master, practised it no more than the Pagan emperors. In the second place, the abrogation of the laws against illicit societies would have been the ruin of the empire, founded essentially upon the principle that the state ought not to admit within its bosom any society differing from it. The principle was bad, according to our ideas: it is very certain, at least, that it was the corner-stone in the Roman constitution. Marcus Aurelius, far from exaggerating it, extenuated it with all his powers; and one of the glories of his reign is the extension of the right of association. However, he did not go to the root: he did not completely abolish the laws against the collegia illicita, and in the provinces there resulted from them some processes infinitely to be regretted. The reproach which can be made against him is the same that might be made to the rulers of our day, who do not suppress with a stroke of the pen all the laws restrictive of the liberties of re-union, of association, and of the press.
