Book 8
5
And friendship is not only indispensable as a means, it is also noble in itself. We praise those who love their friends, and it is counted a noble thing to have many friends; and some people think that a true friend must be a good man.

But there is much difference of opinion as to the nature of friendship. Some define it as a matter of similarity; they say that we love those who are like ourselves: whence the proverbs Like finds his like, Birds of a feather flock together,Literally Jackdaw to jackdaw. and so on. Others on the contrary say that with men who are alike it is always a case of two of a trade.Literally, all such men are potters to each other, an allusion to Hes. WD 25, καὶ κεραμεὺς κεραμεῖ κοτέει καὶ τέκτονι τέκτων—Potter with potter contends, and joiner quarrels with joiner. Some try to find a more profound and scientific explanation of the nature of affection. EuripidesFr. 890 Dindorf, from an unknown play. writes that Earth yearneth for the rain when dried up, And the majestic Heaven when filled with rain Yearneth to fall to Earth. Heracleitus says, Opposition unites, and The fairest harmony springs from difference, and ’Tis strife that makes the world go on. Others maintain the opposite view, notably Empedocles, who declares that Like seeks after like.
