Cassander:  Would you say the love between Achilles and Patroclus is a corrupting _ one _ ?
Aristotle: When men lie together in lust , it is a surrender to the passions and does nothing for the excellence in us . Nor does any other excess , Cassander , jealousy among them . But when men lie together , and knowledge and virtue are passed between them that is pure and excellent . When they compete to bring out the good , the best in each other this is the love between men that can build a city - state and lift us from our frog pond .
