To kill or not to kill, that was the question that haunted me.

It is hard to tell if capital punishment has such an effect. And even if, in some contexts it has (such as in the American South with a very high incidence of murder), this effect may very well go away if a decent welfare state was replaced for the existing social order.

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

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.

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.

What we need is legislation, not negotiation, for the entire globe.

In many European countries we have populist indirect democratic systems. The people elect, in a proportionate manner, a parliament. The parliament with all its parties is representative of the political opinions among the citizens. It is reasonable to claim that the people rule itself through the political institutions.
