More accurately fist/hand = Conscience/brain. Your question is loaded so that by answering the responder must buy into the implicit premise - that consciousness has an independent reality and is not just the nominal word for a brain doing what a brain does. I am not trying to convince you that that is the case, but rather that anyone can prove a philosophical point by setting the question up in a clever way. Your question is no different from "Are you still beating your wife?" - you get the answer you want regardless of what the answer is.
