Abstract
LaFollette argues that the greatest vice is not cruelty, immorality, or selfishness. Rather, it is a failure on our part to ‘engage in frequent, honest and rigorous self-reflection’. It is that failure which, on his view, explains the lion’s share of the wrongdoings we commit towards one another. In this short reply, I raise (in a sympathetic spirit) some questions about the task of identifying the greatest vice, and draw out some of the implications of LaFollette’s account of moral ignorance.
