Context

“And if we add, as we may fairly do, that nothing so powerfully attracts and draws one thing to itself as likeness does to friendship, it will at once be admitted to be true that the good love the good and attach them to themselves as though they were united by blood and nature. For nothing can be more eager, or rather greedy, for what is like itself than nature. So, my dear Fannius and Scaevola, we may look upon this as an established fact, that between good men there is, as it were of necessity, a kindly feeling, which is the source of friendship ordained by nature.” source
