Abstract
Abstractabstract:Interpreters of John Stuart Mill's moral philosophy have long disagreed about whether he was an act or rule utilitarian. Though debate has often focused on Utilitarianism, this paper instead analyzes a less studied work, "Whewell on Moral Philosophy," which contains a more detailed and systematic discussion of moral rules. "Whewell," I argue, favors reading Mill as an act utilitarian: it understands the importance of rules in moral reasoning to arise from the uncertainty under which human action occurs, not from any direct role that rule compliance plays in determining right action.
