"A brief introduction to ethics, one that plays lightly and gracefully over a number of philosophical themes, including the relationship between being good and living well."--Jim Holt, The New Yorker"A slender but rich meditation on why humans should choose to behave well when the possibilities for doing evil are so abundant.... Highly accessible, and highly rewarding."--Kirkus"Simon Blackburn's short book takes the big moral questions head on and does so brilliantly...a witty, vivid write with an enviable popular touch...this is a wonderfully enlightening book."--Ben Rogers, Sunday Telegraph
