The varieties of likeness are very many, and they may be more or less remote. Yet even those which are remote can in time be linked together by various things; chiefly by adapting to the other's desires, by sharing duties, by courtesy, by avoiding unchaste acts, by shared love of babies and taking care of children. Most important is conformity in religious matters, for these bring about the inward linking of even remote likenesses, while the other things only effect an outward linking. But in the case of unlikenesses, no linking is possible since they are hostile.
