My conjecture is that most people will refuse to let go, even when their lives have become boring (at least in comparisons with possible lives lived by new generations). If this happens, there will eventually be no room for new generations. A kind of collective irrationality will lead to a bleak life for the last generation that decides to stay around. Unless we put and end to the human race (through global warming, for example), before this happens, individual egoism will block the path to a better world.

Even where people in different cultures agree they may all have gone wrong.

I was conscripted to military service, and my gut feeling was to refuse to serve. I did not want to kill other people. This seemed to me wrong, if not in principle, so at least in practice.

I do believe that what I have called populist democracy is to be preferred to what I have called elitist democracy.

It is of note that for a long time moral nihilism was a kind of unquestioned default position in analytic moral philosophy.

I am now a decided non-naturalist realist. And today we may even speak of a trend towards non-naturalist moral realism.

It is hard to tell if capital punishment has such an effect. And even if, in some contexts it has (such as in the American South with a very high incidence of murder), this effect may very well go away if a decent welfare state was replaced for the existing social order.
