Abstract
Some observations suggest that friendships are developed and maintained because they involve some form of reinforcement or interpersonal reward. Other observations suggest that friendship has an intrinsic, end-in-itself quality making it unnecessary, if not contradictory, to assume that friendships must be rewarding to be formed and sustained. The present paper outlines a model of friendship based on a conception of self and self-referent motivation. The model represents, in part, an effort to reconcile the observed rewardingness of friendship with its intrinsic, end-in-itself character.
