The problem is that you can't know if the cat is dead or alive unless you open the box.
Schrödinger conceived the experiment to "show" that the premises lead to an absurd result: that the cat is dead and alive at the same time.
But now people either consider it plausible (in multiple universes or depending on observer) or try to explain how superposition is lost before it reaches macroscopic objects.
- n4r9 4y agoRight, I agree with everything you say. To me that means the thought experiment was extremely valuable, because it generated a great refinement of our ontological ideas.
- narag 4y agoIt's funny because the author's idea was to discredit the notion altogether, so it's relevant because it failed to do that. The core of Mary's adventures is a false dicotomy: that matter is the only component of physical reality. But processes, structure and energy flow are as real as matter. Actually, at a very small scale, matter seems to be exactly that. So as usual with all these dualism "enigmas", the only problem is starting from an old perspective that doesn't play well with current knowledge. Consciousness seems to be a complex physical process seen from inside itself. There's no mistery or toughness in that, except that we can't compare it with anything else. We can't use the inside and ouside outlooks at the same time. But Wittgenstein already stated that more than a century ago.
