Roger Caillois is the name of one of the speakers who is scheduled with Michael Leiris to appear at the College de Sociologie with Bataille. Caillois was needed in Argentina and will not return until two months after their speaking engagement. Leiris chooses not to appear because he thinks the role they assign to the sacred does not conform to his interpretation of Mauss' doctrine of total phenomenon. He is also concerned that their efforts may lead to a literary clique despite Bataille's intention to make sure Caillois' and his own work command respect. Bataille confirms any disagreement Leiris has will not exclude future collaboration when terms are better defined.
