He does talk about QM statistical randomness as far as synaptic activity goes, but he states clearly here: "How exactly such weights or probabilities of firing might work is not understood, but Tse argues that weights would constitute "informational" criteria as opposed to being simply physical. They could represent mental events that supervene on the physical brain events." This sounds a lot more like teleology than randomness or determinism. It has to > be either random or determined. Says who? The entity whose every uttering is a random or determined jittering of meaningless neural activity? > If you say it's something else you're > making up something that is not only physically but also logically > impossible. > A clearer statement of psuedoskeptical prejudice I could not hope for. But I can't blame you - all of your responses are generated randomly or automatically and so cannot possibly contain any intentional meaning.
