NARK says: "I feel what we usually call "irrationality" plays a very important, albeit provisional and transitory, role. For instance when one's rationality comes to a crisis, i.e. when our presuppositions change. As a JW I would have sworn that I had been rationally convinced of the three presuppositions to my religious rationality. But now I know this was not the case. I chose to believe because I chose to believe. And I later chose to disbelieve, or believe something else, because I chose so.
I need the light of day. But I also need the darkness of night and its "irrational" dreams (which still belong to language, even though they don't seem so). Both motivate my actions, even if the daylight falsely claims everything."
Hmmm. Are you saying we have to beat our head against the wall to appreciate how much better it feels NOT to?
Presuppositions are __provisional_assessement. They are hypothesis. They are a rough sketch in need of further fleshing out. Reality smacks us and wakes us up and we see what needs erasing and what further details are needed.
Living on Presuppositions is dangerous. All knowledge is provisional. All Concepts must needs remain open to further advancements or refinement.
When we CHOOSE TO BELIEVE we are, in effect saying, "I don't know and my ignorance is the foundation for what I do next".
Most of us can get by with making hundreds of errors. We do so every day. It is not the errors we cherish, however, it is the recalibration that is important. If we do not RECALIBRATE, we are by definition fools. Nobody consciously embraces being a fool.
I'm not really sure how much you are embracing the "darkness". That disturbs me. I'll assume it is hyperbole.
