You have not yet acquired perfect love if your regard for people is still swayed by their characters – for example, if, for some particular reason, you love one person and hate another, or if for the same reason you sometimes love and sometimes hate the same person.
“Mature love says: I need you because I love you.” — Erich Fromm
“Immature love says: ‘I love you because I need you.’ Mature love says: ‘I need you because I love you.’”
“Love is a decision, it is a judgment, it is a promise” — Erich Fromm
“Love is a decision, it is a judgment, it is a promise. If love were only a feeling, there would be no basis for the promise to love each other forever. A feeling comes and it may go. How can I judge that it will stay forever, when my act does not involve judgment and decision.”
