things to be done, nor are slaves compelled to obey us in all things; they will not carry out treasonable orders, or lend their hands to an act of crime.
XXI. There are some things which the law neither enjoins nor forbids; it is in these that a slave finds the means of bestowing benefits. As long as we only receive what is generally demanded from a slave, that is mere service; when more is given than a slave need afford us, it is a benefit; as soon as what he does begins to partake of the affection of a friend, it can no longer be called service. There are certain things with which a master is bound to provide his slave, such as food and clothing; no one calls this a benefit; but supposing that he indulges his slave, educates him above his station, teaches him arts which free-born men learn, that is a benefit. The converse is true in the case of the slave; anything which goes beyond the rules of a slave's duty, which is done of his own free will, and not in obedience to orders, is a benefit, provided it be of sufficient importance to be called by such a name if bestowed by any other person.
XXII. It has pleased Chrysippus to define a slave as "a hireling for life." Just as a hireling bestows a benefit when he does more than he engaged himself to do, so when a slave's love for his master raises him above his condition and urges him to do something noble--something which would be a credit even to men more fortunate by birth--he surpasses the hopes of his master, and is a benefit found in the house. Do you think it is just that we should be angry with our slaves when they do less than their duty, and that we should not be grateful to them when they do more? Do you wish to know when their service is not a benefit? When the question can be asked, "What if he had refused to do it?" When he does that which he might have refused to do, we must praise his good will. Benefits and wrongs are opposites; a slave can bestow a benefit upon his master, if he can receive a wrong from his master. Now an official has been appointed to hear complaints of the wrongs done by masters to their slaves, whose duty it is to restrain cruelty and lust, or avarice in providing them with the necessaries of life. What follows, then? Is it the master who receives a benefit from his slave? nay, rather, it is one man who receives it from another. Lastly, he did all that lay in his power; he bestowed a benefit upon his master; it lies in your power to receive or not to receive it from a slave. Yet who is so exalted, that fortune may not make him need the aid even of the lowliest?
