Abstract
Hume argued against claims about the role of reasoning in moral thought that had been defended by moral rationalists. In doing so, he criticized the doctrines of the rational intuitionist Samuel Clarke (1675–1729). Clarke has not received much attention from contemporary moral philosophers, and given that rational intuitionism has long fallen out of favor, he may seem an unlikely thinker to defend. Nevertheless, attention to his writings reveals some interesting arguments. By considering how Clarke could respond to Hume's attacks, I believe we can make progress in understanding the nature of moral agency and what it is for reasons to have a justifying as well as an explanatory role.
