Re intelligence vs. power: think about it as quality of engine vs. how you apply the engine. You can have a perfect car, and still drown it in a pool. Quality of engine is abstract knowledge about it, it's not derived from performance of that engine on a specific race track. If you are highly intelligent, but get hit by a stone fallen from the sky, it doesn't mean that it was your preferred outcome. When the outcome turns out wrong each time, it shows that your abstract knowledge was wrong, but quality of engine is not outcome itself.
