  • The most widely read defense of the idea that right and wrong depend on how much happiness our actions bring to everyone they affect.
  • Argues that an action is right if it tends to increase happiness and reduce suffering, counting each person's happiness as equal to anyone else's.
  • Argues that following this rule does not mean selfishness, since a good person must weigh a stranger's happiness as fairly as their own.
  • Made this way of thinking (called "utilitarianism," a word Mill helped spread) one of the main approaches to right and wrong still taught in schools today.
  • Shaped later debates on public policy, where governments and economists often judge laws by how much good they do for the greatest number of people.

  • Built from older drafts

    Mill shaped it from notes and drafts he wrote in the 1850s, partly while his wife Harriet was alive.

  • Raised on these ideas

    His father trained him from childhood in the ideas of Jeremy Bentham, which this book defends and reshapes.

  • Attacked from the start
