Abstract

This paper will survey and assess the ways in which moral thinkers in the early modern tradition of casuistry considered a range of cases of conscience (casus conscientiae) relating to lying, deception, and witholding the truth. Arguing that the position of the casuists has been unjustly maligned — not least by Pascal's brillant yet partizan Les Proviniciales — casuistical theories of lying and simulation will be placed in a broad intellectual context which will examine attihules to mendacity among early modern medical writers, political theorists, anbl philosophers. Contrasting casuistical theoriessuch as equivocation and mental reservation with the approach to lying of other early modern writers, the lecture will advancfcahe view that the casuists promulgated a conceptual outlook on the differences betweefc lying and deception which is of inherent interest, and which helps to clarify some of the salient issues that attend a philosophical account of lying
