Yes, you can assign values to different world versions, but each version would have their own values. It's a meaningless (to others), subjective categorization.

Yes, you can assign values to different world versions, but each version would have their own values. It's a meaningless (to others), subjective categorization. There is no solution to the trolley problem where both branches agree to let one branch die. I didn't mean that I do not have any preferences, but that my preferences aren't special or better than others' preferences, in the same way that another version of the world (where Pratchett's wishes were overruled) is not a better world than the current one. I think I'm skirting close to Leibniz here. Yes, the world could be better, but it would not be our world, and it would only be better to some of us, and worse for others. It's highly unlikely that your best Kafka is my best Kafka. As such there is no Best Kafka. The world in which I help Kafka finish The Castle is one in which (for want of a nail) a trillion years from now the Zormulons exterminate the Qdhraxians. I doubt the Qdhraxians are happy I at least got an ending to a story.
