An utterly fascinating interview of Andrea Morris with Penrose is on the web (https://www.youtube.com/watch?v=itLIM38k2r0). It's worth seeing!
We could dare to argue that, according to the "Hemingway Paradox," free will is impossible. It confirms that classic reality is deterministic (not predictable, not pre-deterministic) and quantum reality is random (not predictable, nevertheless determined by the disfinite +1 possibilities of it). When we introduce the randomness of the quantum level (H can shoot or not shoot himself by 'choice' -among the disfinite-n possibilities), blending it with the classic level, we just add randomness, not necessarily a 'free' choice that in any way we cannot explain where it finds motivation. The myriads of disfinite choices+1 of the quantum level just reduce to the myriads of disfinite-1 choices at each level (because the blocks interactions de facto reduce the possibilities until you reach the disfinite-n choices of the H level, each of one getting more and more determined because the more you add blocks interactions (increasing complexity), the more we restrict the potential outcomes of a single action, consequently the more we determine the path that led to that action, paradoxically adding even more potential paths and outcomes that cannot happen. Thinking of a -more naturally- reversed genealogic tree, but starting from the last offspring, this one is the result of two combinations, themselves the result of four combinations, that are the result of eight combinations, and so on. The more we go back, the more the randomness increases. The closer we get to the last output, the more this is determined by the previous combinations -and the environment, the events, and all. The same happens if we consider all the levels of the physical manifestation (and the metaphysical, intended as the 'unknown' at a physical level), from the quantum level to the highest complex one. Admitting that an interaction between the quantum one and the extreme at the other side (the physical universe?) happens (Why not, for what we know?), there is nevertheless no scientific knowledge on how it happens and what it determines, nor if the process is "conscious" -if ever an agreement on what that means will ever be reached! Nor do we know which "purpose" and which kind of "awareness" is involved, considering that both could -and probably are- different (as said: differently defined and differently acted) for each level -if we accept "purpose" and "awareness" as a more comfortable substitute for the sluggish metaphysical abstraction of "consciousness." The only thing we can hypothesize, as a consequence, is that there is a constant exchange of energy (information) within the different levels and among neighboring levels (that decreases exponentially the more we get far from the level in which an event/action happens like it is for the electromagnetic field laws), plus subject to interferences from a myriad of other events (involving energy/information) at each of the interested levels. What we can physically know (avoiding metaphysical unproved speculations) is that we are aware of the purpose of an action at the level in which we find ourselves and maybe at the neighboring levels. However, we cannot know what the purpose is at further levels. The more we go deep toward the quantum level and adventure deep into outer space, the less we know about the "purpose." For example, suppose we destroy a wasp nest near our house. In that case, we know our purpose, that of the wasps resisting the attack; we know the consequences on the neighborhood. We may know the ecological consequences of our actions, or we can imagine or measure them. However, we cannot know what that means at the quantum and the universal level. At all.
Going further, Penrose affirms that a free will decision in the classic reality (H shoot himself), is a posteriori manifested at the quantum level (hence taking the path of the configured classic reality universe that manifests itself). That is a perfect argument against free will. Imagine a universe (our classic reality)in which every single human is given free will and that continuously and incessantly re-configures itself at the quantum level (hence at the classic level, too) because of the decisions of each one of the sentient beings possessing free will. The result is the most amazing, delightful, complete chaos! The schizophrenic paradise, the ultimate circus, the LSD trip of the divine (if it ever existed and exists)! Something that probably Tom Robbins would appreciate, or maybe not. Just imagine if humans really have free will -influencing the quantum-classic realities- and put that together with the vaccine refusal frenzy or the flat-earth theories...
So, yes, the 'Hemingway paradox" is a paradox that demonstrates that it was inevitable that H shot himself that day, at that moment, likely because of what happened to him when he was two years old, of what he witnessed during WWI, what he ate for dinner the day before, and of how he slept that night, plus that particular word he heard or did read on the newspaper at breakfast, and the weather that morning, the eye of the marlin he caught three years before and the cigar that went wet two hours later on the boat, together with the memory of Pordenone ("sad and rainy") many years before (that is really a suicidal trigger, indeed!). Paradoxically, all apparently so casual, but inevitably determined (yet unpredictable and not pre-determined, precisely as it happens at the quantum level) -as much as shooting himself was not, definitely, casual.
And not even chosen.
