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 have now come to the conclusion (roughly) that capital punishment is defensible, if it can be shown to have a deterrent effect on murder. In that case, a few executions save not only some people from being murdered but also some people from becoming murders.

It is quite possible that we will soon come to live under some sort of global despotism, enlightened or not. This is not a nice prospect. And there is only one way of avoiding that this happens: to establish a global democracy. And it is not too late to strive for such a democracy, of a straightforward populist nature, where people on the globe elect a world parliament, which in turn elects a world government.

It is obvious that humanity faces existential threats of a global nature. They are global in the sense that is not possible to deal with them unless we resort to global governance.

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 own ourselves. This is the core of a libertarian theory of rights. But on this theory, while we are at liberty to kill ourselves (regardless of the consequences of others), we are not allowed to kill others, not even if this means that there we be fewer murders in the future, totally speaking.

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.
