As Jon reminded us free will is a spectrum. A few examples ChatGPT helped me to create:Low free will+ Someone has an overwhelming compulsive urge to drink a glass of Jack Daniel's and feels unable to resist it+ Someone automatically pulls their hand away after touching something extremely hot+ Someone threatens to kill you and you hand over your money because you are afraid you will dieMedium free will+ Someone wants to exercise at the gym but has built a habit of checking social media sites on the phone and decides to go later+ Someone wants to eat healthy but is strongly tempted by a new Ben & Jerry's ice cream and eventually gives inHigh free will+ Someone recognizes an impulse, pauses, considers the own values and deliberately chooses whether to act on it+ Someone decides to enroll at Columbia University to study psychology+ After his doctor tells him he has too much weight, someone decides to sign up for a 10km run in his cityBest,Jochen -------- Original message --------From: Eric Charles <[email protected]> Date: 8/17/26 12:31 AM (GMT+01:00) To: The Friday Morning Applied Complexity Coffee Group <[email protected]> Subject: Re: [FRIAM] New philosophy book Well... as you point out in the book, I "Serves as the list's operational skeptic and meeting chronicler. Consistently advocates for "sciencing the problem" and tethering complex philosophical concepts back to empirical behavioral testing (e.g., "rats in mazes")." 😅In that vein I think the crucial starting point would be to find at least a few examples in which we agree someone acted of their own free will and a few examples in which they did not act of their own free will, and integrate those examples to determine the difference. Do I act of my own free will when I select a certain steak from the menu and request a certain doneness? Does the mugging victim act of their own free will when a gun is pointed at their child and their wallet requested? When my kid asks where we are going, and I tell them I want to take the scenic route to school today, was that free will? Etc. Whatever we find freewill to be, when we have finished engaging in that task, I doubt we will find discussion of quantum mechanics or structural-decay-that-might-make-the-past-unknowable to be relevant. (And, by "doubt" I am not asserting certainty of irrelevance, I only mean that I do not think it will be the outcome, but I could be wrong.)

I like the drunkard's streetlight metaphor.Physicists would not agree that "the world" unfolds deterministically. The weather for example that Nick mentions so often is unpredictable in the long run - as you know due to chaos theory and the butterfly effect.Biological systems in turn have and keep low internal entropy because of their high degree of internal order and complexity. Human behavior is operating 4 or 5 levels above the physical level of atoms and molecules, on top of and in a low-entropy biological system.I see the problem differently, more from a human and less from a mere physical perspective. For me the interesting thing is why we can have free will although our behavior is determined by our habits, our emotional reactions, and the character formed by our past environments. By the wiring of our hardware so to speak.The interesting question for me is not if a human mind can magically break the laws of physics by some kind of quantum woo, but how constraints, habits, and conscious interventions interact and which forms of agency emerge from it. But I agree that we should not to let a 17th-century view of the universe dictate the terms of 21st-century thinking. It is probably better to see human freedom and agency as a dynamic spectrum. Some people have fewer cognitive degrees of freedom than others, and there are moments where we show full free will, and others where we lack it.Instead of asking, "Did this person act out of free will?", we should probably better ask "Given their biological state, stress level, history, psychological conditioning, and available information, how many meaningful alternative paths could this system actually evaluate and take in that moment?"-J.-------- Original message --------From: Jon Zingale <[email protected]> Date: 8/15/26 6:21 PM (GMT+01:00) To: The Friday Morning Applied Complexity Coffee Group <[email protected]> Subject: Re: [FRIAM] New philosophy book Jochen,Implicit in many of the group's discussions of free will and determinism is the premise that the world unfolds deterministically, and that the remaining question is whether something extra exists that can escape or modify that mechanism. I do not think that this setup is necessary or given. More importantly, I think it installs a false dichotomy at the center of what may be an ill-posed problem.Locally, and for many purposes, causal accounts work extraordinarily well. We can often treat physical laws as stable, or at least as evolving according to some effective computable rule. We can model bounded domains, specify state variables, solve or approximate equations, and aim to obtain predictive control. Nothing I wish to say here denies that success.But a successful local model is not yet a warrant for the stronger metaphysical conclusion that there exists a complete global state of the universe, that this state retains every relevant distinction in a lossless way, and that its entire evolution is specified by a computable rule. Those are substantive further assumptions.My disagreement with the "aggregation of history" picture begins here. A world with finite physical resources cannot straightforwardly be assumed to be an indefinitely accumulating, lossless record of arbitrarily fine distinctions. Entropy and information bounds are often read as limits on how much information can be stored in a finite region with finite energy. At a minimum, physical history must be represented through selective persistence: some distinctions become stable records, some are dispersed into inaccessible correlations, some are erased relative to a scale of description, and some cease to be recoverable by any physically available process.So I wonder whether *the total state of the universe* is doing more metaphysical work than it has earned. If one allows that the global unfolding may involve non-computable structure, then no finite internal description can, in general, serve as a complete ledger of that unfolding. The universe cannot stand outside itself with a second, lossless copy of its own full history.I am not claiming that noncomputability establishes free will. I am asking whether the familiar determinism vs free will framing already presupposes an idealized total-state picture that may not be physically meaningful.There is a related mathematical point. Scientists understandably favor well-posed models: operators and dynamical systems with domains, regularity, stability, and convergence properties sufficient for analysis and prediction. But those are selected virtues, not neutral evidence that the space of possible physical evolutions is itself globally well behaved. Compact operators, for example, are a special class. They map bounded sets to relatively compact sets and are necessarily bounded, but they are not representative of all operators one might write down. I would like to not confuse the tractability of the mathematical objects we can successfully use with a demonstration that reality is exhausted by such objects.The same caution applies to computability. Under the ordinary Lebesgue measure on the reals, the computable reals form a countable set and therefore a set of *measure-zero*. By contrast, algorithmically random sequences are typical under the fair-coin measure. That is, Martin-Löf random sequences have *measure-one*. Of course, there is no canonical uniform distribution over *all laws* or *all operators*, so this is not a probability calculation showing that physical law is non-computable. It is an admonition against quietly assuming computability merely because computable descriptions are the ones available to us.I am imagining the drunkard under the streetlight metaphor. It is sensible to look where mathematical models offer light: computable dynamics, well-posed initial-value problems, bounded domains, compactness arguments, and stable approximations. But their usefulness does not establish that the deep structure of the universe is confined to those regions of conceptual illumination.For me, the more difficult thought is that materialism may imply not a perfectly preserved cosmic archive, but an unfolding in which persistence is selective and forgetting is real. Perhaps there is no complete *deep history* available even in principle. Instead there may only exist present structures bearing partial, transformed, scale-dependent traces of what preceded them. I am tempted to say that what leaves no trace whatsoever *never existed* in any ontologically robust sense. I suppose I am arguing for a surprisingly shallow image of history.If so, the future may be genuinely productive (immanence) rather than merely unknown to us. Not necessarily because an agent steps outside causality, but because the global boundary conditions, state description, and rule of unfolding are not available in the form demanded by classical determinism.This may make *free will* the wrong label. We may all be acting in ways that are locally causal, constrained, and intelligible while global determinism remains undefined, ungrounded, or simply irrelevant. I do not yet know what positive concept should replace it. But I do not think that uncertainty should be hidden by accepting the *determinism vs free will* dichotomy as our starting point.My two cents.Jon .- .-.. .-.. / ..-. --- --- - . .-. ... / .- .-. . / .-- .-. --- -. --. / ... --- -- . / .- .-. . / ..- ... . ..-. ..- .-..
