There are some particular moral truths that I believe we have access to (such as the one not to inflict pain on a sentient being for no reason).

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.

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.

There comes a time where next to everyone will resort to techniques that enhance cognitive, mental including emotive, physical, and other capacities. When this has happened, if not before, the ban on doping in sport will have been lifted.

The Chinese are generally speaking much more reluctant than Westerners to killing as a means to the rescue of lives.

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

Are there any good arguments in defence of moral nihilism? I think not.
