Key ideas in Philosophical Stress Tests
- Thought experiments control variables by stripping out confounding emotional biases.
- Abstract framing isolates whether a specific feature alone drives moral judgment.
- Messy real-world details often mask the core ethical principle being tested.
- Double effect permits foreseen harm only if it is not the chosen instrument.
- Using a person's death as the causal lever to save others violates the doctrine.
- Side effects are unintended costs that run parallel to the primary goal.
- The shallow pond argument treats geographic distance as morally arbitrary.
- Physical proximity triggers stronger psychological urgency without altering duty.
- Failing to donate life-saving aid is framed as equivalent to watching a child drown.
- A reductio accepts the premise and follows its logic to an unacceptable conclusion.
- Forced organ harvesting from one healthy person to save five tests strict utilitarianism.
- Exposing intolerable derived outcomes proves a rule is an ad-hoc rationalization.
- The control principle states agents are only morally blameworthy for factors under their direct control
- Resultant luck alters consequences without altering the reckless choice or internal culpability of the agent
- Equal recklessness warrants identical moral censure when outcomes hinge purely on extrinsic chance
- Constitutive luck concerns the involuntary formation of an agent's predispositions, traits, and temperament
