Hi Phatboy,
The main point I was trying to make is that logic is only one possible ingredient that contributes to an individual's worldview. Many of us don't articulate our worldview, let alone analyze or critique it, and so don't even notice conflicting or unclear aspects. So long as it "feels right", or comfortable.
Like Dan, I think our fears, and whatever we need to keep them at bay, have a lot to do with it.
That's why I enjoy the way this forum challenges us to examine ourselves.
The chart is certainly easier to read than the middle two websites! I'll respond more detail when I've done a bit of research, but for now, although I don't deny the possible existence of absolute truths, I cannot imagine how we'd recognise one.
