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.

It is true (independently of our conceptualisation) that it is wrong to inflict pain on a sentient creature for no reason (she doesn't deserve it, I haven't promised to do it, it is not helpful to this creature or to anyone else if I do it, and so forth). But if this is a truth, existing independently of our conceptualisation, then at least one moral fact (this one) exists and moral realism is true. We have to accept this, I submit, unless we can find strong reasons to think otherwise.

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

The democratic thought is based on that 'ordinary people' are suitable to rule themselves.

Actually, I defend the right to free abortion.

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.

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