That is a KEY part of intelligence that MOST people alive today (intractable problems) have NO CLUE the concept even exists (everything HAS an ANSWER a CORRECT answer). If you add up EVERYTHING mankind KNOWS, it doesn't come to ONE MILLIONTH on ONE percent of what there is LEFT to know, and if you DO NOT know EVERTYHING, you CANNOT know ANYTYING really (take it ALL into account) and it's STILL (probably) a SUBJECTIVE (taste) issue. What do you want? What do you need? I don't KNOW. Once you get there in thinking, your "engines" start to FAIL (no point, even though survival STILL looks attractive). To what END? I'm clueless. Sailing! (good weather to ya BTW). SEEMED attractive at one point, then LOST it's luster, BUT under different ("right") circumstances, I imagine it would REAPPEAR on MY radar screen as a "best thing I can think of" option. Oh (from earlier). Didn't mean to mash up heaving to with bare poles. two different heavy weather strategies. Typiing too fast ( another problem I have).
