We hope for lives whose story leaves us looking admirable; we like our weaknesses to be hidden and deniable... We want to enjoy our lives, and we want to enjoy them with a good conscience... Ethics is disturbing. We are often vaguely uncomfortable when we think of such things as exploitation of the world's resources, or the way our comforts are provided by the miserable labour conditions of the third world... Racists and sexists, like antebellum slave owners in America, always have to tell themselves a story that justifies their system.

Simon Blackburn, Being Good (2001)
