Friendship (e-book) (used book) | Daniel J. Hruschka | bookbook.eu

Description

Friends-they are generous and cooperative with each other in ways that appear to defy standard evolutionary expectations, frequently sacrificing for one another without concern for past behaviors or future consequences. In this fascinating multidisciplinary study, Daniel J. Hruschka synthesizes an array of cross-cultural, experimental and ethnographic data to understand the broad meaning of friendship, how it develops, how it interfaces with kinship and romantic relationships, and how it differs from place to place. Hruschka argues that friendship is a special form of reciprocal altruism based not on tit-for-tat accounting or forward-looking rationality, but rather on mutual goodwill that is built up along the way. Using mathematical models, he shows that such an approach to cooperation can resist exploitation at the hands of false friends, while addressing adaptive problems of mutual aid. Hruschka provides a novel and comprehensive treatise on the anthropology, biology, psychology, and sociology of this essential and universal human relationship.
