Аннотация:Historical epistemology is a form of intellectual history focused on “the history of categories that structure our thought, pattern our arguments and proofs, and certify our standards for explanation” (Lorraine Daston). Under this umbrella, historians have been studying the changing meanings of “objectivity,” “impartiality,” “curiosity,” and other virtues believed to be conducive to good scholarship. While endorsing this historicization of virtues and their corresponding vices, the present article argues that the meaning and relative importance of these virtues and vices can only be determined if their mutual dependencies are taken into account. Drawing on a detailed case study—a controversy that erupted among nineteenth-century orientalists over the publication of R. P. A. Dozy's De Israëlieten te Mekka (The Israelites in Mecca) (1864)—the paper shows that nineteenth-century orientalists were careful to examine (1) the degree to which Dozy practiced the virtues they considered most important, (2) the extent to which these virtues were kept in balance by other ones, (3) the extent to which these virtues were balanced by other scholars’ virtues, and (4) the extent to which they were expected to be balanced by future scholars’ work. Consequently, this article argues that historical epistemology might want to abandon its single-virtue focus in order to allow balances, hierarchies, and other dependency relations between virtues and vices to move to the center of attention.
