For these reasons it is not a fit thing to be thus unsparing of our virtue, uniting and intertwining it now with one and now with another, but rather only with those who are qualified to keep up the same participation, that is to say, those who are able, in a like manner, to love and participate. For herein plainly is the greatest obstacle of all to having a multitude of friends, in that friendship comes into being through likeness. Indeed, if even the brute beasts are made to mate with others unlike themselves only by forcible compulsion, and crouch aside, and show resentment as they try to escape from each other, while with animals of their own race and kind they consort with mutual satisfaction, and welcome the participation with a ready goodwill, how then is it possible for friendship to be engendered in differing characters, unlike feelings, and lives which hold to other principles? It is true that the harmony produced on harp and lyre gets its consonance through tones of dissonant pitch, a likeness being somehow engendered between the higher and the lower notes; but in our friendship’s consonance and harmony there must be no element unlike, uneven, or unequal, but all must be alike to engender agreement in words, counsels, opinions, and feelings, and it must be as if one soul were apportioned among two or more bodies.
