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.

You should not take the content of your intuitive response as evidence until you have submitted your psychological reaction to what I call cognitive psychotherapy. You should do what you can to learn as much as possible about the origin of your reaction.

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

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

Once we realise that utilitarianism comes with the idea of blameworthy rightdoing (such as when you push a big man onto the tracks in order to save five lives) and blameless wrongdoing (such as when you don't push a big man onto the tracks in order to save five lives), then utilitarianism all of a sudden appears to give the right answers.

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

It is of note that even if utilitarianism has proved to be superior to deontology and the libertarian moral rights theory in the area of killing, we are not allowed to say that it has been finally vindicated; it has to face other challenges in other areas, in particular in situations of distributive justice.
