Williams objects to utilitarianism on the grounds that it cannot account for the importance of moral integrity and a person's sense of identity. Utilitarianism views people only as a means to maximize utility, leaving no room for understanding how a person's deeply held projects and sense of self relate to their actions. Williams also objects to Kantianism, arguing that in some cases acting from duty alone cannot be the right motivation and that not all actions can be adequately justified by abstract, impartial principles.
