If two norms conflict, if they are mutually inconsistent, then at least one of them must be false.

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

When I was in my late teens I was already interested in philosophy.

People in different cultures think very differently about abortion. Abortion is not seen as a moral problem for example in Sweden or Russia, but it is seen as a difficult moral problem in China and in the USA.

We can be certain that, if there are conflicting views in different cultures, some of these views must be false. This may help us to transcend our own narrow cultural horizon.

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.

Utilitarianism condones killing of innocent human beings, even murder, if it makes the world a better place.
