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

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.

I am a left winger, thought.

How could it be that I had a legal obligation to kill people I did not know, and who did certainly not consent to it, while my father's doctor could not help my father to die when my farther asked for it? My consternation brought me to moral philosophy and a life-long search for an answer to the question when and why we should, and when we shouldn't, kill.

One way of submitting your moral intuitions in relation to some issue to cognitive therapy is to learn more about how people in other cultures think about it.

Normative ethics, pursued as a free, systematic, and critical attempt to find moral truth, regardless of religious and other authorities, is a rather new adventure. Let's wait and see what will happen!

I believe that one basic question, what we ought to do, period (the moral question), is a genuine one. There exists a true answer to it, which is independent of our thought and conceptualisation.
