One man, when he has done a service to another, is ready to set it down to his account as a favour conferred. Another is not ready to do this, but still in his own mind he thinks of the man as his debtor, and he knows what he has done. A third in a manner does not even know what he has done, but he is like a vine which has produced grapes, and seeks for nothing more after it has once produced its proper fruit. As a horse when he has run, a dog when he has tracked the game, a bee when it has made the honey, so a man when he has done a good act, does not call out for others to come and see, but he goes on to another act, as a vine goes on to produce again the grapes in season.- Must a man then be one of these, who in a manner act thus without observing it?- Yes.- But this very thing is necessary, the observation of what a man is doing: for, it may be said, it is characteristic of the social animal to perceive that he is working in a social manner, and indeed to wish that his social partner also should perceive it.- It is true what thou sayest, but thou dost not rightly understand what is now said: and for this reason thou wilt become one of those of whom I spoke before, for even they are misled by a certain show of reason. But if thou wilt choose to understand the meaning of what is said, do not fear that for this reason thou wilt omit any social act.
