Neither determined nor random

I found the following in David Wiggins’s paper “Towards a reasonable libertarianism” (from the 1973 anthology Essays on Freedom of Action, edited by Ted Honderlich) and found it relevant to my recent posts on free will.

[C]an the libertarian even specify a possible world, however different from the actual one, in which there are particular responsible actions which people can (in the libertarian’s sense) do but do not do? Hume has been followed by a large number of philosophers in holding that not even a possible world of the required sort could be specified. If it were false that every event and every action were causally determined then the causally undetermined events and actions would surely, to that extent, be simply random. So the argument goes. That a man could have done x would mean no more than that it might have turned out that way — at random. It will be asked if it makes any better sense to hold a man responsible for actions which happen at random than for ones which arise from his character. Surely then, if it doesn’t, we ought to prefer that our actions be caused?

This is essentially the same argument I’ve been making. I might have known that Hume came up with it first. (That I didn’t know Hume came up with it first is a humbling reminder of just how spotty and haphazard my philosophical education has been. And Hume is one of the thinkers I’m relatively more familiar with, compared to some of the other big names in philosophy!)

Considered simply as an argument this objection is circular, and flagrantly so. One cannot prove that determinism is a precondition of free will by an argument which employs as a premiss everything is either causally determined or random. This is nothing other than a form of the conclusion, that whatever is undetermined is random. This is what had to be shown. But in the form of a challenge something in the objection can stand. If an event is undetermined, if an event of different specification might have taken place, then what does it mean to deny that the event is simply random? What is it justifiably to ascribe the action identical with the event or comprised of the event to an agent whom one holds responsible for that action? In the unclaimed ground between the properly or determinatically [sic] caused and the random, what is there in fact to be found?

This is well put. (Okay, I take that back. I mean, determinatically?) The argument is indeed circular, because it isn’t really a proper argument at all, so much as a bare assertion of something which seems self-evident: that everything is either causally determined or random (or some combination of the two), that those two options exhaust the logical possibilities. The challenge for the libertarian is to show this to be a false dichotomy by coherently describing a third possibility. Later in the paper, Wiggins attempts to do so.

For indeterminism maybe all we really need to imagine or conceive is a world in which (a) there is some macroscopic indeterminacy founded in microscopic indeterminacy, and (b) an appreciable number of the free actions or policies or deliberations of individual agents, although they are not even in principle hypothetico-deductively derivable from antecedent conditions, can be such as to persuade us to fit them into meaningful sequences. We need not trace free actions back to volitions construed as little pushes aimed from outside the physical world. What we must find instead are patterns which are coherent and intelligible in the low level terms of practical deliberation, even though they are not amenable to the kind of generalisation or necessity which is the stuff of rigorous theory. On this conception the agent is conceived as an essentially and straightforwardly enmattered or embodied thing. His possible peculiarity as a natural thing among things in nature is that his biography unfolds not only non-deterministically but also intelligibly; non-deterministically in that personality and character are never something complete, and need not be the deterministic origin of action; intelligibly in that each new action or episode constitutes a comprehensible phase in the unfolding of the character, a further specification of what the man has by now become.

This is an intriguing line of thought. Thinking of intelligible (rather than determined) as the opposite of random offers a different angle from which to view the problem. I’m still not sure it really works, though.

Certainly it is possible in principle for something to be non-deterministic and yet intelligible. The proof of this is that extremely complex systems (the weather, the behavior of other people, etc.), even if it happens to be true that they are “really” completely deterministic, cannot be perceived that way by us. We can see some regularities, enough to make them intelligible to us, but we can’t possibly understand all the causes involved. Even if they are deterministic (which they may be), they are psychologically indistinguishable from truly non-deterministic systems; therefore, if they are intelligible to us, it follows that a truly non-deterministic system could also be intelligible.

But surely (and this is again an assertion of what seems self-evident, not an argument) what makes such systems intelligible is that the randomness is constrained, not that it is not random. Even if truly random processes played a role in, say, the weather, the weather would still be intelligible because it follows certain broadly predictable patterns, because the randomness is not unconstrained. A typhoon may happen to grow stronger or weaker, to last a certain number of days rather than a certain other number, to blow back out to the sea rather than making landfall. I don’t understand why it does the one thing rather than the other, and therefore those aspects of its behavior may as well be truly random as far as I am concerned — but it remains intelligible. If, on the other hand, the behavior of typhoons were pure unconstrained randomness, exhibiting no regularities at all, it would be unintelligible.

The same goes for human behavior. If it is truly non-deterministic and yet intelligible, all it seems to me that that could mean is that it contains randomness, but randomness which is constrained enough that it can still be broadly intelligible. But it’s still just a combination of determinism and randomness.

  1. The Problem with Freewill is that it is so Intangibly Obvious as to What is Required for It to Be FreeWill, That there are very few approaches to Solving It. ( ? )

    There are Only Two Observable Mechanisms for Freewill to Operate from;
    And One ( Randomality ) is only theoretically Existent.
    For Freewill to become Operational; Choices must be ‘Directionally’ Deterministic.
    That is; We ( Our Homunculi ) Makes ‘Deliberate Choices’ for Very Sound Reasons.

    The Missing KeyStone is ‘Intelligent Determinism’.
    As soon as someone comes up with a blueprint for this to incorporate into robots,
    The Debate of Freewill will come immediately to a resolution.

    As to The Moral Dilemma of Hold The Criminal Responsible for Their Actions;
    It is Tautologically Obvious that If this Interpretation of Reality Holds True,
    Then The Judge Can Make The Same Argument / or Defense, for his Actions When Sentencing The Accused to Be Hanged until Dead.
    The Judge is Just as Surely A Victim of Determinism as The Criminals.

    Concerning Hume’s Question :
    If an event is undetermined, if an event of different specification might have taken place, then what does it mean to deny that the event is simply random?
    – –
    The Problem with Creating a Dichotomy of Determinism vs Randomality,
    Is that Determinism is generally equated to Dominoes, but Real Life Determinism is much closer to a Raging Hurricane of Chaos that Fills The Entire Universe.
    Everything Influences The Outcome of Everything Else.
    ( Nearly So; Gravity & Electromagnetism extend to Infinity, But some Particles Selectively Interact with Only Some other Particles, Never mind those that Rarely Behave in Either Manner. )
    In Such a Chaotic Fashion; All Deterministic occurrences would surely appear Random,
    As their Actual Causality could never be nailed down.

    i had some difficulty following Wiggin’s argument;
    So Assuming your Analysis is accurate:
    “This is an intriguing line of thought. Thinking of intelligible (rather than determined) as the opposite of random offers a different angle from which to view the problem.”
    – –
    This is Addressing what i call ( And many others ) ‘Emergent Complexity’ in which Determinism in Robots can Express Genuine Intelligence & Perform ALL The Tasks & Vices that Humans are observed performing…
    But — That is Still Determinism. It is very clever Determinism, but no New Mechanism has been introduced.

    Before relenting to your ( wm jas ) analysis, It seemed to me that Wiggin’s was arguing that There are, by some unspecified method, teeny tiny sparks of randomality being mixed with The Deterministic ElectroChemical Activity of The Brain to Generate Consciousness & FreeWill.
    This Argument as been presented many times, sometimes by presumed deep thinkers, Such as Roger Penrose’s MicroTubules to explain Consciousness & Presumably Freewill.
    This is yesterdays meatloaf.
    Tiny Sparks of Randomality = Randomality.

    Emergent Complexity doesn’t need A Random Number Generator,
    It will make plenty of Diverse Choices based on The Chaotic Flood of Sensory Inputs.

    Randomality in The Argument for Freewill is A Great Red Herring.

    What is really needed is an entirely new species of Goldfish.

    [ wm jas ] : “Even if they are deterministic (which they may be), they are psychologically indistinguishable from truly non-deterministic systems; therefore, if they are intelligible to us, it follows that a truly non-deterministic system could also be intelligible.”

    That sound’s very ‘counterintuitive’ ( ??? ) that a Non-Deterministic System could be Intelligible.
    You’d either have to insert into this argument a mechanism of ‘Non-Determinism’
    Or Redefine what you mean by ‘Intelligible’.
    i suspect that my own deep rooted ‘Contrarianism’ has kicked in on this one,
    And i am suddenly drawn to The Idea that what we perceive as ‘Intelligible’ is highly subjective, or perhaps entirely wrong.
    Wouldn’t it be delicious if while ‘Consciousness’ & ‘Awareness’ are Completely Real,
    Our ‘Innate Rationalization of What is Intelligible’ is Completely Delusional?
    The World ( Reality & The Universe ) are completely Random, and for some reason, The Sentient Mind believes that it’s all making sense.

    That Interpretation Solves Everything.

    And lastly; i completely refute The Idea / Suggestion that combining ‘Constrained’ Randomality to Determinism, Solves anything.
    Randomality ( Which probably doesn’t even exist, unless of course, it’s The Only Thing that Exists ) would defeat Determinism.

    i believe that Randomality & Determinism are Entirely Exclusionary Principles.

  2. @chrstphre, I don’t suppose I might persuade you to utilize capitalization and line breaks in more mainstream fashion? The erratic presentation, reminiscent of characterized insanity, makes it surprisingly difficult to take your comments seriously.

    @Wm_Jas, might I suggest you read a bit about entropy (the information-theoretic version, http://en.wikipedia.org/wiki/Entropy_(information_theory))? You seem to be saying that “intelligible” = “low entropy”. That’s a fine definition, but not the one most people mean; I think, rather, that “algorithmicaly simple non-entropic elements” is more common; that is, we can readily discover the structure behind the non-entropy portions of intelligible systems, while for unintelligible systems that structure remains elusive.

    I also find myself increasingly confused by what you mean by “random.” Do you mean random variable (not controlled-for nor modeled but measurable), probabilistic (obeying particular patterns in aggregate), chaotic (magnifying perturbations over time), stochastic (not modeled by any combination of Turing-complete operations)? Do you mean the vernacular “neither predictable nor controllable” or “too complicated to understand”? Perhaps the conceptual extreme of “perpetually surprising in perpetually surprising ways and never agreeing with any generalizations whatever, not even this one”?

  3. Luther, I agree with your comment to Chrs, but good luck getting him to change. We’re just lucky the WordPress comment form doesn’t allow for multicolored fonts with shadows and colorful backgrounds.
