Dani,
I believe you are correct in a very important way. However, reasoning must have at least a foundation of objectivity (concrete right wrong) in order for it to be reasoning. I'm not sure if you're familiar with Mark Twain's quote on common sense, but it also had some validity in a very important way. But I do see your point, that the most direct cognitive route often bring this to sensible conclusions and intuitively is self preserving. Thank you for your contribution.
