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.

The US two party system is very different, of course. Here the people decides about who should rule them, but it is not reasonable to claim that the people rules itself through the political institutions. In comparison, I find that the standard European system is better, also as a model for global democracy.

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.

I have been brought up in a culture where capital punishment is indeed anathema. I have always thought of myself as a principled opponent to capital punishment. However, when thinking about how the topic is handled in other cultures, in particular the American, Russian and Chinese ones, I have realised that my own tack on the issue was utterly superficial.

Different areas present us with possibilities to test different theories.

I wanted to know what it means to know something, whether we can know at all, and, if so, how.

The best explanation why people agree is that they have converged on true answers.
