This image floating around the internet addresses the common trolley problem of ethics, which was invented by philosopher Philippa Foot. Do you throw the switch and kill one person or do nothing and allow five people to be killed?
In the past, we've examined absurd variations of this thought experiment, the the actual practice of railroad engineers who have to deal with the problem on a regular basis, and a solution developed by a 2-year old.
This variation, which is floating around the internet, imagines two scenarios: one in which the train kills an infinite number of people tied to the track and the other in which it continuously kills a finite number of continuously reincarnating people.
Which option do you choose?
