Nor do men usually say people are united in sentiment merely because they agree in opinion on _any_ point, as, for instance, on points of astronomical science (Unity of Sentiment herein not having any connection with Friendship), but they say that Communities have Unity of Sentiment when they agree respecting points of expediency and take the same line and carry out what has been determined in common consultation. Thus we see that Unity of Sentiment has for its object matters of action, and such of these as are of importance, and of mutual, or, in the case of single States, common, interest: when, for instance, all agree in the choice of magistrates, or forming alliance with the Lacedæmonians, or appointing Pittacus ruler (that is to say, supposing he himself was willing). But when each wishes himself to be in power (as the brothers in the Phœnissæ), they quarrel and form parties: for, plainly, Unity of Sentiment does not merely imply that each entertains the same idea be it what it may, but that they do so in respect of the same object, as when both the populace and the sensible men of a State desire that the best men should be in office, because then all attain their object. Thus Unity of Sentiment is plainly a social Friendship, as it is also said to be: since it has for its object-matter things expedient and relating to life. And this Unity exists among the good: for they have it towards themselves and towards one another, being, if I may be allowed the expression, in the same position: I mean, the wishes of such men are steady and do not ebb and flow like the Euripus, and they wish what is just and expedient and aim at these things in common. The bad, on the contrary, can as little have Unity of Sentiment as they can be real friends, except to a very slight extent, desiring as they do unfair advantage in things profitable while they shirk labour and service for the common good: and while each man wishes for these things for himself he is jealous of and hinders his neighbour: and as they do not watch over the common good it is lost. The result is that they quarrel while they are for keeping one another to work but are not willing to perform their just share. Chapter VII. Benefactors are commonly held to have more Friendship for the objects of their kindness than these for them: and the fact is made a subject of discussion and enquiry, as being contrary to reasonable expectation. The account of the matter which satisfies most persons is that the one are debtors and the others creditors: and therefore that, as in the case of actual loans the debtors wish their creditors out of the way while the creditors are anxious for the preservation of their debtors, so those who have done kindnesses desire the continued existence of the people they have done them to, under the notion of getting a return of their good offices, while these are not particularly anxious about requital.
