Quantum mind by physicists, some of which regard the "alive and dead" cat superposition as quite real. Schrödinger's famous thought experiment poses the question, ""when" does a quantum system stop existing as a superposition of states and become one or the other?" In the same way, it is possible to ask whether the brain's act of making a decision is analogous to having a superposition of states of two decision outcomes, so that making a decision means "opening the box" to reduce the brain from a combination of states to one state. But even Schrödinger didn't think this really happened to the
Big Book (thought experiment) Big Book (thought experiment) The "Big Book" is a thought experiment developed by Ludwig Wittgenstein about the nature of ethics and the verifiability of ethical knowledge. This account is given by him in an early work, the 1929 "Lecture on Ethics", and it matches also his position given in the early "Tractatus Logico-Philosophicus" (Proposition 6.41).
