Abstract
In this paper, I examine critically Kimberley Brownlee’s descriptive criteria for identifying when a person has a conscientious moral conviction. Then, I contrast her conception of conscience with other ideas of conscience, including a religious conception, a relativist conception, and those of Butler and Kant. The concepts examined here are central in her argument that, if civil disobedience is grounded in citizens’ conscience-based conscientious convictions, then it deserves legal and moral protection.
