Roger Caillois
Fascinated by human sacrifice, he founded a secret society, "Acéphale", the symbol of which was a headless man. According to legend, Bataille and the other members of Acéphale each agreed to be the sacrificial victim as an inauguration; none of them would agree to be the executioner. An indemnity was offered for an executioner, but none was found before the dissolution of Acéphale shortly before the war. The group also published an eponymous review of Nietzsche's philosophy which attempted to postulate what Derrida has called an "anti-sovereignty". Collaborators in these projects included André Masson, Pierre Klossowski, Roger Caillois, , Jean Rollin and Jean Wahl.
