“Value difference” is often used as a cop-out. How did our terminal values come to be so different, anyway? If I’m extremely selfish and you’re extremely selfish, we will likely have very different values, but if we are both altruistic, our values are combinations of values of all the other people in the world, so they should be pretty similar. For example, if I think society should be organized like an anthill and you think it should be organized like a pool of sharks (to borrow Ken Binmore’s example), this is a factual disagreement about what would make everyone better off, not a value disagreement.
