Because I am uncertain about some people, I'll start with the uncertainty. Some people that base their life exclusively on rational thinking seem to be happy if everything in their physical world is alright. They also seem (to me, subjectively) to be somewhat cold, boring, lacking the spark of life. So it's a mystery to me. Are they happy? Are they only kidding themselves? I have no idea. So I leave them out of the equation. For the rest of you lovely people I have some certainties.
