Kyle York came up with a few, here is one of them:
There’s an out of control trolley speeding towards Immanuel Kant. You have the ability to pull a lever and change the trolley’s path so it hits Jeremy Bentham instead. Jeremy Bentham clutches the only existing copy of Kant’s Groundwork of the Metaphysic of Morals. Kant holds the only existing copy of Bentham’s The Principles of Morals and Legislation. Both of them are shouting at you that they have recently started to reconsider their ethical stances.
For the pointer I thank Dennis Boyle.
