One of Einstein’s students asked him, “What does logic mean?” Einstein replied with a question: “Suppose two workers go down a chimney to clean it. One comes out with a dirty face, and the other comes out with a clean face. Who will wash their face?” The student immediately answered, “The one with the dirty face.” Einstein said, “That answer is not correct. The person with the clean face would wash their face because they would see that their colleague’s face was dirty and assume their own face was dirty too. The person with the dirty face would see that the other person’s face was clean and assume their own face was also clean.” The student said, “That makes sense.” Einstein replied, “No. The question itself is not logical. If both workers went into the same chimney at the same time, it would not make sense for one to come out clean and the other dirty.” The lesson is simple: Sometimes the problem is not the answer. The problem is the question itself.
