Abstract

Augustine devoted two treatises to the topic of lying, De Mendacio and Contra Mendacium ad Consentium. The treatises raise interesting questions about whatlying is while defending the thesis that all lies are sinful. The first part of this essay offers an interpretation of Augustine’s attempts at definition. The second part exanlines his argunlents for the sinfulness of lying used to trap heretics and for the more general thesis that all lying is sinful
