The distinction between ‘passion’ and ‘emotion’ has been largely overlooked in the history of psychiatry and the psychopathology of affectivity. A version of the distinction that has gone completely unnoticed is the one proposed by Florentine physician Vincenzo Chiarugi (1759–1820). The purpose of the present discussion is to introduce this Italian version of the distinction and to inquire into its origins.

Locke is famous for defining madness as an intellectual disorder in the realm of ideas. Numerous commentators take this to be his main and only contribution to the history of psychiatry. However, a detailed exegetical review of all the relevant textual evidence suggests that this intellectualist interpretation of Locke’s account of madness is both misleading and incomplete. Affective states of various sorts play an important role in that account and are in fact primordial in the determination of human conduct generally. (...) Locke’s legacy in this domain must therefore be revised and the intellectualist bias that dominates discussions of his views must be redressed. (shrink)
