This paper argues that reliabilist virtue epistemology is mistaken. Descartes supposes a supremely powerful deceiver is determined to trick him into believing falsehoods. Beliefs Descartes cannot rationally doubt, even allowing the demon’s best efforts, count as indubitable knowledge. I give an instance of indubitable knowledge and argue that it is not attributable to an epistemic competence. Since not all knowledge is virtuous, knowledge cannot be identified with virtuous true belief.
