41 | What Can Moral Dilemmas Tell Us About Ourselves? ~ Peter Railton

On Humans

You are driving a car. The brakes stop working. To your horror, you are approaching a busy street market. Many people might be killed if you run into them. The only way to prevent a catastrophe is by turning fast to the right. Unfortunately, a lonely pedestrian might be killed if you do so.

Should you turn? Many people say you should. After all, killing one is better than killing many. But following the same logic, would you kill an individual to collect their organs for people in dire need of one? In this case, too, you would kill one to save many. Yet very few are willing to do so.

Why?

These are variations of the infamous “trolley problems”. Originally formulated half a century ago, these trolley problems continue to elicit heated conversations. They have a whole ⁠meme culture⁠ built around them. Yet for years, I was not convinced of their value. They seemed to squeeze ethics into narrow funnels of “yeses" and "noes", neglecting much of real life's texture.

I have changed my mind. And I’ve done so largely thanks to Peter Railton.

A professor of philosophy at UC Michigan, Railton used to share my scepticism about the trolley problems. But he, too, changed his mind. Having in-depth conversations about them with his students, Railton came to see these problems as revealing some important about morality. Combined with recent evidence from psychology and neuroscience, Railton believes that these insights can reveal a lot about the human mind more generally.

I will let him tell you why.
