that Lenten season when Lacordaire was preaching in Lyons, proves that, though devoting himself with ardor to the study of economical problems, Proudhon had not lost his interest in questions of religious history. Among his writings on these questions, which he was unfortunately obliged to leave unfinished, we may mention a nearly completed history of the early Christian heresies, and of the struggle of Christianity against Cæsarism.
