“Perhaps the most legitimately dispiriting thing about reciprocal altruism is that it is a misnomer. Whereas with kin selection the "goal" of our genes is to actually help another organism, with reciprocal altruism the goal is that the organism be left under the impression that we've helped; the impression alone is enough to bring the reciprocation.”
“Longing is not always a reciprocal thing.”
“What interferes with this peaceful feeling is our expectation of reciprocity.”
“Reciprocity is not mandatory.”
“You're as good as you reciprocate.”
“Love has to be reciprocated for it to be real.”
