In On Virtue Ethics I offered a criterion for a character trait's being a virtue according to which a virtuous character trait must conduce to, or at least not be inimical to, four ends, one of which is the continuance of the human species. I argue here that this does not commit me to homosexuality's being a vice, since homosexuality is not a character trait and hence not up for assessment as a virtue or a vice. Vegetarianism is not up for such assessment either, for the same reason, but, as a practice, may well be required by the virtue of compassion, and sacrificing one's life for an animal or alien may be required by courage. The clause about the continuance of the human species in my criterion does not specify a foundational value, because, following McDowell, I reject foundationalism.
