Mark Walker's fascinating paper calls for a Genetic Virtue Program (GVP)—an interdisciplinary effort to enhance human ethics. He urges that we achieve this by “promoting genes that influence the acquisition of the virtues.” Although the GVP is a worthy focus of philosophical debate, I have to confess to some doubts about its viability. We patently don't live in the best of all possible worlds, but I'm skeptical about the notion that the way to improve the world is to make deliberate and specific ethical or moral enhancements.
