If this be so, no one ever gave himself a benefit, because no one gives to himself; if not, two opposites coalesce, so that it becomes the same thing to give and to receive. Yet there is a great difference between giving and receiving; how should there not be, seeing that these words are the converse of one another? Still, if anyone can give himself a benefit, there can be no difference between giving and receiving. I said a little before that some words apply only to other persons, and are so constituted that their whole meaning lies apart from ourselves; for instance, I am a brother, but a brother of some other man, for no one is his own brother; I am an equal, but equal to somebody else, for who is equal to himself? A thing which is compared to another thing is unintelligible without that other thing; a thing which is joined to something else does not exist apart from it; so that which is given does not exist without the other person, nor can a benefit have any existence without another person. This is clear from the very phrase which describes it, “to do good,” yet no one does good to himself, any more than he favours himself or is on his own side. I might enlarge further upon this subject and give many examples.
