INSIGHT

Purpose Of Moral Thought Experiments

  • Moral thought experiments are artificial by design to isolate and test one factor in our moral reasoning.
  • David Edmonds argues this simplification helps clarify which features drive our intuitions in ethics.
ANECDOTE

Trolley Problem And Public Intuition

  • The trolley problem asks whether to flip a switch to save five by killing one, or push a person to stop the train and save five at the cost of one.
  • Experiments show most people approve flipping the switch but reject pushing the person despite identical casualties.

Consequences Include Psychological Ripples

  • Sam Harris suggests consequentialism can account for differences by including psychological and social ripples as consequences.
