This chapter deals with Cyrenaic positions on personal and civic relationships, beginning with a short overview of assumptions about positive and negative reciprocity in ancient Greek culture—friendship and enmity, benefaction and injury, intra-polis solidarity and inter-polis war, etc. The chapter then looks at the tension between involvement in these cultural institutions and withdrawal into self-sufficiency, which develops from Aristippus through mainstream Cyrenaicism. This tension is abolished by Hegesias and Theodorus, who repudiate all of the relationships involved and embrace what we might call ethical solipsism. Finally, the chapter analyzes how Anniceris opposes Hegesias by reappraising the importance of friendship, filial piety, and civic participation for effective hedonism.
