Whether likeness is a cause of love?

❌ Objection 1 : It would seem that likeness is not a cause of love. For the same thing is not the cause of contraries. But likeness is the cause of hatred; for it is written (Prov. 13:10) that "among the proud there are always contentions"; and the Philosopher says (Ethic. viii, 1) that "potters quarrel with one another." Therefore likeness is not a cause of love.

❌ Objection 2 : Further, Augustine says (Confess. iv, 14) that "a man loves in another that which he would not be himself: thus he loves an actor, but would not himself be an actor." But it would not be so, if likeness were the proper cause of love; for in that case a man would love in another, that which he possesses himself, or would like to possess. Therefore likeness is not a cause of love.

❌ Objection 3 : Further, everyone loves that which he needs, even if he have it not: thus a sick man loves health, and a poor man loves riches. But in so far as he needs them and lacks them, he is unlike them. Therefore not only likeness but also unlikeness is a cause of love.

❌ Objection 4 : Further, the Philosopher says (Rhet. ii, 4) that "we love those who bestow money and health on us; and also those who retain their friendship for the dead." But all are not such. Therefore likeness is not a cause of love.
