Key ideas in The Big Questions of Philosophy

  • Consequentialism judges whether an act was right or wrong strictly by its end results
  • Deontology argues that certain moral rules—like telling the truth—must never be broken, even for a good outcome
  • A deontologist views lying as inherently wrong even if it saves a life
  • A moral dilemma happens when two equally valid principles clash directly
  • Whichever choice you make in a true dilemma, you inevitably violate a moral commitment
  • Dilemmas produce unavoidable moral regret because there is no win-win escape
  • Both actors made the exact same reckless moral choice with identical intentions
  • People assign far harsher moral blame based purely on an outcome determined by chance
  • Moral luck exposes the contradiction that we hold people responsible for factors beyond their control
  • The doctrine of double effect allows an action with bad side effects only if the bad effect was not the chosen goal or necessary means
  • Using a bad outcome directly as the stepping stone to reach a good end is forbidden under this rule
  • Foreseeing that harm will happen alongside your good act is morally distinct from aiming at the harm
  • An entity inside your moral circle has interests that matter for their own sake, not just for how useful they are to you
  • Expanding the circle means geographic distance or species boundaries no longer automatically disqualify someone from ethical consideration
  • Entities outside your moral circle are treated merely as tools or resources
  • Eudaimonia is human flourishing achieved through an entire lifetime of living and acting well
