XVI. I might go on for ever collecting instances to prove that valuable things are sold at a low price. What then? why is it that I owe something extra both to my physician and to my teacher, and that I do not acquit myself of all obligation to them by paying them their fee? It is because they pass from physicians and teachers into friends, and lay us under obligations, not by the skill which they sell to us, but by kindly and familiar good will. If my physician does no more than feel my pulse and class me among those whom he sees in his daily rounds, pointing out what I ought to do or to avoid without any personal interest, then I owe him no more than his fee, because he views me with the eye not of a friend, but of a commander. [Footnote: I read "Nbn tamquam amicus videt sed tamquam imperator.">[ Neither have I any reason for loving my teacher, if he has regarded me merely as one of the mass of his scholars, and has not thought me worthy of taking especial pains with by myself, if he has never fixed his attention upon me, and if when he discharged his knowledge on the public, I might be said rather to have picked it up than to have learnt it from him. What then is our reason for owing them much? It is, not that what they have sold us is worth more than we paid for it, but that they have given something to us personally. Suppose that my physician has spent more consideration upon my case than was professionally necessary; that it was for me, not for his own credit, that he feared: that he was not satisfied with pointing out remedies, but himself applied them, that he sat by my bedside among my anxious friends, and came to see me at the crises of my disorder; that no service was too troublesome or too disgusting for him to perform; that he did not hear my groans unmoved; that among the numbers who called for him I was his favourite case; and that he gave the others only so much time as his care of my health permitted him: I should feel obliged to such a man not as to a physician, but as to a friend. Suppose again that my teacher endured labour and weariness in instructing me; that he taught me something more than is taught by all masters alike; that he roused my better feelings by his encouragement, and that at one time he would raise my spirits by praise, and at another warn me to shake off slothfulness: that he laid his hand, as it were, upon my latent and torpid powers of intellect and drew them out into the light of day; that he did not stingily dole out to me what he knew, in order that he might be wanted for a longer time, but was eager, if possible, to pour all his learning into me; then I am ungrateful, if I do not love him as much as I love my nearest relatives and my dearest friends.
XVII. We give something additional even to those who teach the meanest trades, if their efforts appear to be extraordinary; we bestow a gratuity upon pilots, upon workmen who deal with the commonest materials and hire themselves out by the day. In the noblest arts, however, those which either preserve or beautify our lives, a man would be ungrateful who thinks he owes the artist no more than he bargained for. Besides this, the teaching of such learning as we have spoken of blends mind with mind; now when this takes place, both in the case of the physician and of the teacher the price of his work is paid, but that of his mind remains owing.
XVIII. Plato once crossed a river, and as the ferryman did not ask him for anything, he supposed that he had let him pass free out of respect, and said that the ferryman had laid Plato under an obligation. Shortly afterwards, seeing the ferryman take one person after another across the river with the same pains, and without charging anything, Plato declared that the ferryman had not laid him under an obligation. If you wish me to be grateful for what you give, you must not merely give it to me, but show that you mean it specially for me; you cannot make any claim upon one for having given him what you fling away broad-cast among the crowd. What then? shall I owe you nothing for it? Nothing, as an individual; I will pay, when the rest of mankind do, what I owe no more than they.
XIX. "Do you say," inquires my opponent, "that he who carries me gratis in a boat across the river Po, does not bestow any benefit upon me?" I do. He does me some good, but he does not bestow a benefit upon me; for he does it for his own sake, or at any rate not for mine; in short, he himself does not imagine that he is bestowing a benefit upon me, but does it for the credit of the State, or of the neighbourhood, or of himself, and expects some return for doing so, different from what he would receive from individual passengers. "Well," asks my opponent, "if the emperor were to grant the franchise to all the Gauls, or exemption, from taxes to all the Spaniards, would each individual of them owe him nothing on that account?" Of course he would: but he would be indebted to him, not as having personally received a benefit intended for himself alone, but as a partaker in one conferred upon his nation. He would argue, "The emperor had no thought of me at the time when he benefited us all; he did not care to give me the franchise separately, he did not fix his attention upon me; why then should I be grateful to one who did not have me in his mind when he was thinking of doing what he did? In answer to this, I say that when he thought of doing good to all the Gauls, he thought of doing good to me also, for I was a Gaul, and he included me under my national, if not under my personal appellation. In like manner, I should feel grateful to him, not as for a personal, but for a general benefit; being only one of the people, I should regard the debt of gratitude as incurred, not by myself, but by my country, and should not pay it myself, but only contribute my share towards doing so. I do not call a man my creditor because he has lent money to my country, nor should I include that money in a schedule of my debts were I either a candidate for a public office, or a defendant in the courts; yet I would pay my share towards extinguishing such a debt. Similarly, I deny that I am laid under an obligation by a gift bestowed upon my entire nation, because although the giver gave it to me, yet he did not do so for my sake, but gave it without knowing whether he was giving it to me or not: nevertheless I should feel that I owed something for the gift, because it did reach me, though not directly. To lay me under an obligation, a thing must be done for my sake alone."
XX. "According to this," argues our opponent, "you are under no obligation to the sun or the moon; for they do not move for your sake alone." No, but since they move with the object of preserving the balance of the universe, they move for my sake also, seeing that I am a fraction of the universe. Besides, our position and theirs is not the same, for he who does me good in order that he may by my means do good to himself, does not bestow a benefit upon me, because he merely makes use of me as an instrument for his own advantage; whereas the sun and the moon, even if they do us good for their own sakes, still cannot do good to us in order that by our means they may do good to themselves, for what is there which we can bestow upon them?
XXI. "I should be sure," replies he, "that the sun and the moon wished to do us good, if they were able to refuse to do so; but they cannot help moving as they do. In short, let them stop and discontinue their work."
See now, in how many ways this argument may be refuted. One who cannot refuse to do a thing may nevertheless wish to do it; indeed there is no greater proof of a fixed desire to do anything, than not to be able to alter one's determination. A good man cannot leave undone what he does: for unless he does it he will not be a good man. Is a good man, then, not able to bestow a benefit, because he does what he ought to do, and is not able not to do what he ought to do? Besides this, it makes a great difference whether you say, "He is not able not to do this, because he is forced to do it," or "He is not able to wish not to do it;" for, if he could not help doing it, then I am not indebted for it to him, but to the person who forced him to do it; if he could not help wishing for it because he had nothing better to wish for, then it is he who forces himself to do it, and in this case the debt which as acting under compulsion he could not claim, is due to him as compelling himself.
"Let the sun and moon cease to wish to benefit us," says our adversary. I answer, "Remember what has been said. Who can be so crazy as to refuse the name of free-will to that which has no danger of ceasing to act, and of adopting the opposite course, since, on the contrary, he whose will is fixed for ever, must be thought to wish more earnestly than any one else. Surely if he, who may at any moment change his mind, can be said to wish, we must not deny the existence of will in a being whose nature does not admit of change of mind."
XXII. "Well," says he "let them stop, if it be possible." What you say is this:—"Let all those heavenly bodies, placed as they are at vast distances from each other, and arranged to preserve the balance of the universe, leave their appointed posts: let sudden confusion arise, so that constellations may collide with constellations, that the established harmony of all things may be destroyed and the works of God be shaken into ruin; let the whole frame of the rapidly moving heavenly bodies abandon in mid career those movements which we were assured would endure for ages, and let those which now by their regular advance and retreat keep the world at a moderate temperature, be instantly consumed by fire, so that instead of the infinite variety of the seasons all may be reduced to one uniform condition; let fire rage everywhere, followed by dull night, and let the bottomless abyss swallow up all the gods." Is it worth while to destroy all this merely in order to refute you? Even though you do not wish it, they do you good, and they wheel in their courses for your sake, though their motion may be due to some earlier and more important cause.
XXIII. Besides this, the gods act under no external constraint, but their own will is a law to them for all time. They have established an order which is not to be changed, and consequently it is impossible that they should appear to be likely to do anything against their will, since they wish to continue doing whatever they cannot cease from doing, and they never regret their original decision, No doubt it is impossible for them to stop short, or to desert to the other side, but it is so for no other reason than that their own force holds them to their purpose. It is from no weakness that they persevere; no, they have no mind to leave the best course, and by this it is fated that they should proceed. When, at the time of the original creation, they arranged the entire universe, they paid attention to us as well as to the rest, and took thought about the human race; and for this reason we cannot suppose that it is merely for their own pleasure that they move in their orbits and display their work since we also are a part of that work. We are, therefore; under an obligation to the sun and moon and the rest of the heavenly host, because, although they may rise in order to bestow more important benefits than those which we receive from them, yet they do bestow these upon us as they pass on their way to greater things. Besides this, they assist us of set purpose, and, therefore, lay us under an obligation, because we do not in their case stumble by chance upon a benefit bestowed by one who knew not what he was doing, but they knew that we should receive from them the advantages which we do; so that, though they may have some higher aim, though the result of their movements may be something of greater importance than the preservation of the human race, yet from the beginning thought has been directed to our comforts, and the scheme of the world has been arranged in a fashion which proves that our interests were neither their least nor last concern. It is our duty to show filial love for our parents, although many of them had no thought of children when they married. Not so with the gods: they cannot but have known what they were doing when they furnished mankind with food and comforts. Those for whose advantage so much was created, could not have been created without design. Nature conceived the idea of us before she formed us, and, indeed, we are no such trifling piece of work as could have fallen from her hands unheeded. See how great privileges she has bestowed upon us, how far beyond the human race the empire of mankind extends; consider how widely she allows us to roam, not having restricted us to the land alone, but permitted us to traverse every part of herself; consider, too, the audacity of our intellect, the only one which knows of the gods or seeks for them, and how we can raise our mind high above the earth, and commune with those divine influences: you will perceive that man is not a hurriedly put together, or an unstudied piece of work. Among her noblest products nature has none of which she can boast more than man, and assuredly no other which can comprehend her boast. What madness is this, to call the gods in question for their bounty? If a man declares that he has received nothing when he is receiving all the while, and from those who will always be giving without ever receiving anything in return, how will he be grateful to those whose kindness cannot be returned without expense? and how great a mistake is it not to be thankful to a giver, because he is good even to him who disowns him, or to use the fact of his bounty being poured upon us in an uninterrupted stream, as an argument to prove that he cannot help bestowing it. Suppose that such men as these say, "I do not want it," "Let him keep it to himself," "Who asks him for it?" and so forth, with all the other speeches of insolent minds: still, he whose bounty reaches you, although you say that it does not, lays you under an obligation nevertheless; indeed, perhaps the greatest part of the benefit which he bestows is that he is ready to give even when you are complaining against him.
