We can only see the world through the eyes we develop as we grow up. Therefore our understanding is a result of our upbringing.

Also:

"Comprehension is a hierarchy, resembling a pyramid, with awareness at the base followed by consciousness, succeeded by knowing, with understanding at the pinnacle".

Now this idea of a pyramidial hierarchy is probably a product of your experience of the above. I don't think you can really regard any one as being more important than the three others. All our ideas are the product of the interaction of all four. In fact I'm sure others at SAGG might like to have more or less than four in any similar pyramid they might conceive.

Another of your comments:

"It was normal 4 years ago to think that America should invade Iraq".

I'm probably abnormal then. Mind you we weren't exposed here to the massive propaganda being delivered to US and British citizens.
