Me : No. It starts with observation, then hypothesis (i.e. orientation) then a decision to test a hypothesis (i.e. act) and then more observation ... in a big long running OODA loop stretching over many millenia.
Me : Hmmm. Excellent point. I stand corrected. You could simply start with action ... just walk over the hill with no purpose, no reason, no hypothesis ... just for the sake of walking.
