Full Idea
Two distinct motives go by the name of altruism: the emotions of liking, love and friendship, making another's interest automatically mine; and the moral motive of respect or considerateness, where another's interests become reasons for me, but not mine.
Gist of Idea
Altruism is either emotional (where your interests are mine) or moral (where they are reasons for me)
