Translating Renaissance Neoplatonic panpsychism into seventeenth-century corpuscularism: the case of Sir Kenelm Digby (1603–1665)

Abstract

ABSTRACT Kenelm Digby was among the first authors in England to embrace Cartesianism. Yet Digby’s approach to the mind–body problem was irenic: in his massive Two treatises (Paris, 1644), the author advocates a corpuscular philosophy that is applied to physical bodies, whereas the intellectual capacities of human beings remain inexplicable through the powers of matter. The aim of the present article is to highlight the (rather reticent) relationship of Digby’s corpuscularism with doctrines of spirits in connection with the Renaissance Neoplatonic tradition. Not uncommon in seventeenth-century natural philosophies, such “spirits” are notoriously evasive entities: half spirit, half matter acting as mediators between the realms of bodies and souls. This article suggests that Digby sought to preserve the inveterate ideas of a universal spiritus and a world soul and, in particular, that Kenelm Digby translated (rather than “overcame”) Marsilio Ficino’s (1433–1499) spiritus doctrines into the language of seventeenth-century corpuscularism.
