In 1976 Bernard Williams and Thomas Nagel each wrote a paper called “Moral Luck”. We say people should be judged only on what they could control, they noticed, and then we judge them on how things turned out. Williams’s example was the painter Gauguin; Nagel’s, a careless driver.
How to play it
Make the same choices for two drivers. Then judge them.
We say a choice should be judged by what the chooser could control, and then we judge it by how it turned out. Nagel thought we can’t stop doing either.
Ask yourself. Whose decision are you judging by how it turned out, not by what they knew?
That’s the whole collection examined, every room. Now imagine doing this with your own life, for a year, with two people who come to know it well. That’s membership.
