Pegs and holes: In defense of quantum mysticism

[Alex K]

While it is tempting to search for the ineffable "thereness" of consciousness in the realm of quantum states, where due to their seemingly nonlocal nature (one joint wavefunction for the entire brain?) they appear to correspond to the perceived one-ness of the self, I don't quite see how this is viable. Stuff the size of the brain with the temperature of the brain should decohere instantly (i.e. develop strong entanglement with the environment), so it would first of all act like a classical non quantum system, and second of all, the new wavefunction must be one of the brain and the surrounding world including all other people jointly - this breakdown of individuality is not observed subjectively though, making me think that quantum plays no essential part in the brain at scales beyond a neuron.
