Furthermore, Friendship seems to be the bond of Social Communities, and legislators seem to be more anxious to secure it than Justice even. I mean, Unanimity is somewhat like to Friendship, and this they certainly aim at and specially drive out faction as being inimical.
Again, where people are in Friendship Justice is not required;202 but, on the other hand, though they are just they need Friendship in addition, and that principle which is most truly just is thought to partake of the nature of Friendship.
Lastly, not only is it a thing necessary but honourable likewise: since we praise those who are fond of friends, and the having numerous friends is thought a matter of credit to a man; some go so far as to hold, that “good man” and “friend” are terms synonymous.
Chapter II.
Yet the disputed points respecting it are not few: some men lay down that it is a kind of resemblance, and that men who are like one another are friends: whence come the common sayings, “Like will to like,” “Birds of a feather,” and so on. Others, on the contrary, say, that all such come under the maxim, “Two of a trade never agree.”203
Again, some men push their enquiries on these points higher and reason physically: as Euripides, who says,
“The earth by drought consumed doth love the rain,
And the great heaven, overcharged with rain,
Doth love to fall in showers upon the earth.”
Heraclitus, again, maintains, that “contrariety is expedient, and that the best agreement arises from things differing, and that all things come into being in the way of the principle of antagonism.”
