Book 6.14

"Well, then," says he, "suppose that I were to order all your names to be put into a ballot-box, and that your name was drawn among those who were to be ransomed, would you owe me nothing?" Yes, I should owe you something, but very little: how little, I will explain to you. By so doing you do something for my sake, in that you grant me the chance of being ransomed; I owe to fortune that my name was drawn, all I owe to you is that my name could be drawn. You have given me the means of obtaining your benefit. For the greater part of that benefit I am indebted to fortune; that I could be so indebted, I owe to you.

I shall take no notice whatever of those whose benefits are bestowed in a mercenary spirit, who do not consider to whom, but upon what terms they give, whose benefits are entirely selfish. Suppose that some one sells me corn; I cannot live unless I buy it; yet I do not owe my life to him because I have bought it. I do not consider how essential it was to me, and that I could not live without it; but how little thanks are due for it, since I could not have had it without paying for it, and since the merchant who imported it did not consider how much good he would do me, but how much he would gain for himself, I owe nothing for what I have bought and paid for.
