The principle that observation is the judge imposes a severe limitation to the kind of questions that can be answered. They are limited to questions that you can put this way: “If I do this, what will happen?” There are ways to try it and see. Questions like, “Should I do this?” and “What is the value of this?” are not of the same kind. Richard Feynman
