Again, it is perhaps absurd to make our Happy man a solitary, because no man would choose the possession of all goods in the world on the condition of solitariness, man being a social animal and formed by nature for living with others: of course the Happy man has this qualification since he has all those things which are good by nature: and it is obvious that the society of friends and good men must be preferable to that of strangers and ordinary people, and we conclude, therefore, that the Happy man does need Friends. But then, what do they mean whom we quoted first, and how are they right? Is it not that the mass of mankind mean by Friends those who are useful? and of course the Happy man will not need such because he has all good things already; neither will he need such as are Friends with a view to the pleasurable, or at least only to a slight extent; because his life, being already pleasurable, does not want pleasure imported from without; and so, since the Happy man does not need Friends of these kinds, he is thought not to need any at all. But it may be, this is not true: for it was stated originally, that Happiness is a kind of Working; now Working plainly is something that must come into being, not be already there like a mere piece of property. If then the being happy consists in living and working, and the good man’s working is in itself excellent and pleasurable (as we said at the commencement of the treatise), and if what is our own reckons among things pleasurable, and if we can view our neighbours better than ourselves and their actions better than we can our own, then the actions of their Friends who are good men are pleasurable to the good; inasmuch as they have both the requisites which are naturally pleasant. So the man in the highest state of happiness will need Friends of this kind, since he desires to contemplate good actions, and actions of his own, which those of his friend, being a good man, are. Again, common opinion requires that the Happy man live with pleasure to himself: now life is burthensome to a man in solitude, for it is not easy to work continuously by one’s self, but in company with, and in regard to others, it is easier, and therefore the working, being pleasurable in itself will be more continuous (a thing which should be in respect of the Happy man); for the good man, in that he is good takes pleasure in the actions which accord with Virtue and is annoyed at those which spring from Vice, just as a musical man is pleased with beautiful music and annoyed by bad. And besides, as Theognis says, Virtue itself may be improved by practice, from living with the good.
