A body of work in ethics and epistemology has advanced a collectivist view of virtues. Collectivism holds that some social groups can be subjects in themselves which can possess attributes such as agency or responsibility. Collectivism about virtues holds that virtues (and vices) are among those attributes. By focusing on two different accounts, I argue that the collectivist virtue project has limited prospects.
