[The republic of "humours": Scholarly quarrels in Bayle's dictionary].

Quarrelling is a 'routine' activity of the Republic of Letters. This article demonstrates that quarrels played a key role in the field of historical criticism. The contention of this article is twofold. First, it explores the epistemological issues raised by Bayle while reporting the quarrels of the Republic of Letters, and demonstrates their creative potential, thus applying to historiography conclusions drawn by recent research on scientific controversies. It offers a new understanding of scholarly quarrels, here understood as a socially and intellectually structuring activity. Second, this article takes issue with the debate over Bayle's historical pyrrhonism. As will be shown, the quarrels constitute a key element within a method of writing history that is both conscious of its limits and confident of its investigative powers.
