now my school of analytical nihilism (i just started it, btw) goes even further in criticism. we could even grant that this interaction were possible between these two ontologically distinct substances... and we'd still not have a case of genuine freewill. we would have to ask what compels the immaterial self to interact as it does with the material world, which it is not a part of, without itself being subject to some form of immaterial causality. that is to say, we'd have to posit an infinite regress of 'freewills' to get around this dilemma.
so if you ax me about the cash value of this fact, i'd admit that there is very little to it; we still live in a world as if we have freewill. it certainly seems like we do, and as such we have to find a workable way to live that sustains this illusion without it causing collateral damage. problem is, it's causing a whole lotta collateral damage in ethics (and criminal justice, especially). this is something peacegirl was very attentive to and wrote a lot about.
the great paradox here is that abandoning belief in freewill actually has the opposite effect of fatalism and places more responsibility on man to control his environment and the causes within it. and of course you'd say 'but even that would be part of the dominos toppling over', yes. i admit that at this point we have not yet worked out a way to deal with this redundancy, but our research does show great promise. we're now working on a theory called polymeric causal holism. its central thesis is that when a certain threshold of determined events occurs, an emergent self-determining effect results and is able to separate itself from the causal chain from which it evolved and direct itself as if it had freewill. but this doesn't happen on an individual level. it happens on a ecological level... and by ecological i mean the interactions between environment, intelligent animals, and language users.
no just kidding. there still ain't no freewill. i wuz just bullshitting.
As we move through childhood, with the help of our parents, we hopefully begin to control our impulses and desires. For example, we learn that we can’t have everything exactly when we want it, and so learn to delay gratification, developing self-control. As we need less care and attention from our parents, we exercise more autonomy, learn to make more decisions for ourselves and to follow our own interests and goals. In this sense, human development is a process of becoming less bound by biological and environmental influences and gain more free will and autonomy. And ideally, this process should continue throughout our lives.

Not sure I entirely believe it, but it sure sounds cool.
At any rate, I'll settle for 'unpredictable will', which kicks determinism out the window. Kinda.
Spiritual development can also be seen as a process of gaining increased autonomy. For example, many Eastern spiritual traditions, such as Buddhism or yoga, place great emphasis on self-discipline and self-control: control of our own behaviour, so that we no longer cause harm to others; control of our desires, so that we no longer lust after physical pleasures; control of our thoughts, so that we can quieten the mind through meditation, and so on. In some traditions, spiritual development is seen as a process of ‘taming’ the body and mind, and this is, of course, only possible through intense self-discipline, requiring self-control.
Although it can sometimes occur suddenly and spontaneously, the deep serenity and intensified awareness of spiritual awakening is usually the culmination of a long process of increasing our innate quotient of personal freedom to the point where our minds become the dominant influence. When spiritually awakened people are referred to as ‘masters’, this could easily refer to them as being masters of themselves.
Neuroscience cannot find the self (even less the free agent) for two reasons. Firstly, it doesn’t examine the person but the isolated nervous system and it is an unproven and highly implausible assumption that the person really is the isolated nervous system.
Secondly, it approaches the nervous system from the impersonal standpoint of physical chemistry so that the brain boils down to sets of semi-permeable membranes along which electrochemical impulses propagate. While the brain is a necessary condition of the self (the beheaded are pretty selfless), we should not expect to find the self in a stand-alone bit of brain but in a brain that is part of a body environed by the natural world and a massively complex, historically evolved, culture. Uprooting the brain from all this is a sure-fire way of mislaying the self.
In Western philosophy, Friedrich Nietzsche meant something similar ["being masters of themselves"] with his concept of ‘self-overcoming’. Nietzsche spoke disparagingly of the ‘Ultimate Man’, who is completely satisfied with himself as he is and strives only to make his life as comfortable and pleasurable as possible. But in reality, says Nietzsche, human nature is not fixed or finished. Human beings are part of an evolutionary process – not a goal, but a bridge – “a rope fastened between animal and Superman” (Thus Spake Zarathustra, 1891). The potential Superman is the human being who is not self-satisfied, who has the urge to ‘overcome himself.’ For him, life is an attempt at bridging the gulf between animal and superman.
Liberating Freedom
We all possess a degree of freedom, and we all have the capacity to extend the degree of freedom we’re bequeathed – to become less dominated by our genes, our brain chemistry, and the society and wider environment into which we’re born. We are all potentially much more powerful than we have been led to believe, even to the extent of being able to alter or even control the forces that have been supposed to completely control us. And to a large extent our well-being, our achievements and our sense of meaning in life depend on this. The more you exercise and increase your freedom, the more meaningful and fulfilling your life will be.
The eeriest episode in Charles Dickens’ A Christmas Carol is the visit to Ebenezer Scrooge of the Ghost of Christmas Yet To Come. The shrouded specter transports the old man to a bedroom where his own corpse lies “plundered and bereft, unwatched, unwept, uncared for,” and then to his grave in a churchyard “overrun by grass and weeds.” When Scrooge begs to “see some tenderness connected with a death” the ghost conducts him to the Cratchit family grieving over the death of Tiny Tim. Profoundly shaken, Scrooge implores: “Assure me that I yet may change these shadows you have shown me, by an altered life!” The ghost remains silent, but we know from the end of Dickens’ tale that Scrooge begins altering his life on Christmas day.
Fate & Freedom
This story differs in a philosophically interesting way from fatalistic tales of protagonists who, although warned about calamities to come, are unable to avoid them. Oedipus for example, as foretold in prophecy, is fated to kill his father and marry his mother regardless of the steps taken to prevent these deeds from happening. Ignorant of how exactly his fate will unfold, and blind to its inevitability, he becomes the instrument of his own destruction.
Scrooge, on the other hand, wisely asks whether the future that he has glimpsed is inevitable: “Are these the shadows of the things that Will be, or are they shadows of things that May be, only?” He sees at once the critical difference: “Men’s courses will foreshadow certain ends, to which, if persevered in, they must lead… But if the courses be departed from, the ends will change.” Although the ghost remains silent, Scrooge bets on “May be” rather than “Will be.” Hoping that his fate is up to him, he begins to mend his miserly ways.
Scrooge’s mending of his miserly ways is relevant to current debates about free will because of the ‘consequence’ argument. The consequence argument asserts that if past events and the laws of nature determine everything that will ever happen, then no one has any choice about anything. There is no free will.
Since visits by ghosts violate the laws of nature, one might doubt that the consequence argument applies to Scrooge’s story at all. We can sidestep this doubt by interpreting his encounters as dreams or hallucinations. Dreams and hallucinations are natural events, and they have natural causes. Indeed, Scrooge himself suggests this interpretation when he says to the first ghost, his old partner, Jacob Marley, “There is more of gravy than of grave about you, whatever you are!” Given a naturalistic interpretation, Scrooge’s hallucination of the Ghost of Christmas Yet To Come is just another link in the causal chain. Past events, such as eating greasy gravy for dinner, and the laws of nature, have made it inevitable that Scrooge will have this terrifying vision, that he will resolve to become a better man, and that he will make a good start of it. These developments are lucky for Scrooge and the people around him; but if they are the necessary consequences of chains of events that started long before he was born, it seems doubtful that he can take credit for his change of heart, or be said to have done it out of free will.
Past & Future
Philosophers have been debating antecedents of the consequence argument since antiquity, but it gained new credibility at the end of the Seventeenth Century from the dazzlingly accurate predictions of Isaac Newton’s physics of matter and motion. In 1814, the Marquis de Laplace summarized what he took to be the implications of it: “We ought then to regard the present state of the universe as the effect of its anterior state and the cause of the one that is to follow” (A Philosophical Essay on Probabilities, translated from the sixth French Edition by F.W. Truscott and F.L. Emory). This position is now known as determinism. Laplace claimed that if an intelligence (often called ‘Laplace’s demon’) were vast enough to know and analyze all the conditions and forces of nature at a certain moment, then “the future, as the past, would be present to its eyes.”
In 1884 William James argued that determinism is tragic because it deprives us of any opportunity to make the future better than it is destined to be. Determinism, he says, implies an ‘iron block’ universe where the “future has no ambiguous possibilities bidden in its womb; the part we call the present is compatible with only one totality. Any other future complement than the one fixed from eternity is impossible” (‘The Dilemma of Determinism’, The Will to Believe: & Other Essays in Popular Philosophy).
In 1983, Peter van Inwagen breathed new life into this old argument about determinism and its consequences. He asserts: “Determinism is quite simply the thesis that the past determines a unique future.” He fleshes out this thesis with a lot of technical details, but restates it less technically in a later essay: “Determinism says that the past (the past at any given instant, a complete specification of the universe at any given instant in the past) and the laws of nature together determine everything, that they leave no open possibilities.” He argues that if determinism is true, then it consigns us to a predestined future: “it is not up to us what went on before we were born, and neither is it up to us what the laws of nature are. Therefore, the consequences of these things (including our present acts) are not up to us.”
Causation & Free Will
All versions of the consequence argument begin with the premise that determinism is true. But is it?
First, there is disagreement over how to define determinism.
Van Inwagen gives one common definition. Often, however, it is defined as universal causation – the thesis that everything that happens is caused by prior events and the laws of nature. But although this thesis may be true of a great many events, it is not true of every event.
Most physicists believe that atoms and their parts are governed by the merely statistical probabilities of quantum mechanics, rather than by strict causal necessity. They believe, for example, that the emission of an electron from the nucleus of a radioactive atom at any particular time is not determined by prior events, but instead just happens (albeit with a measureable probability). This means that there is an element of pure chance or irreducible randomness in the timing of such emissions, or in any other quantum activity. We can hear this randomness by listening to the clicks of a Geiger counter.
...like Spinoza before him, Nietzsche is a naturalist and a determinist. Human beings are not privileged over other animals – rather, like them, we are part of “a causal web that comprises the whole universe.” Where other writers speak of the freedom of the human will, Nietzsche tells us that the will is neither free nor unfree, but rather strong or weak.
For Simon Blackburn he was the first philosopher to try to assimilate Darwinism. Nietzsche’s The Genealogy of Morals is an exercise in ‘animal psychology’, studying (in Nietzsche’s own words) “the physiology and evolutionary history of organisms and concepts.” In a number of other central works Nietzsche embraces science as providing access to what he sees as ‘the real world of nature’ – whereas our religious, moral and aesthetic sentiments belong only to the surface of things.
Through our need to see the universe as existing for the sake of human beings, in effect we create a merely apparent world, which for Nietzsche is “the value-laden world as error.” To what degree we can live in truth not error is another matter, of course: in some moods Nietzsche praises the value of art precisely as that it protects us from reality. He dares us to be superficial. But it is nonetheless a central intention in his writings precisely to strip us of our illusions – not least the fundamental illusion that we are rational creatures.
Some philosophers seek to save free will...by bringing in indeterminism, such as a measure of quantum randomness in the operations of our brains. However, randomness in the relevant brain activity would actually threaten free will. An action triggered by a random event would be more like an uncontrolled spasm than a voluntary choice.
Indeed, free will seems to require that our choices and actions be determined in accordance with our beliefs and desires, not simply left to chance. If you found yourself choosing to do what you don’t want to do, and don’t believe you should be doing – say, hitting your head against a wall – you would probably think you were losing your mind rather than exercising your free will. So even advocates of free will might have a stake in defending the claim that causal determination is in force when we choose a course of action.
Another popular view among philosophers today rejects the equation of free will with being able to do otherwise under the exactly the same circumstances. This view claims that free will and moral responsibility can be understood in ways that make them compatible with determinism.
These compatibilists believe that free will and moral responsibility are grounded in special features of deterministic causal processes that produce voluntary choice and action.
Among the causes they stress are: 1) Guidance of our actions by our personal core values; and, 2) Correction of our selves and values through rational responses to what we learn about ourselves and the world. But the consequence argument threatens to nullify these grounds of supposed compatibility by declaring that if determinism is true, then no process of guidance or self correction can alter in the slightest the future that awaits us.
Consider Scrooge again. Although he resolves to alter the course of his life by becoming a better man, and begins his transformation by the end of A Christmas Carol, the consequence argument implies that whatever success he makes will be the actualization of an unavoidable future, not the alteration of a malleable one.
The human brain is adept at picking out short causal chains and inferring outcomes from them. I infer that the tennis ball that you just lobbed over the net is going to come down in the back right corner of the court. You infer that the half pound of salt I accidentally dropped in the stew is going to make the stew taste salty. We rely on inferences such as these to guide our actions: to return a tennis ball, or to avoid eating salty stew. However, our ability to infer future events in this way is limited. We have difficulty foreseeing the results of clashes with other causal chains, such as a sudden gust of wind that blows the tennis ball off the court. Moreover, we are not adept at inferring the future from the remote, or even the relatively recent, past. I cannot infer where the tennis ball is going to land now from events that happened yesterday, much less a thousand years ago.
Does our ability to infer the future, albeit in limited ways, enable us to alter the future in any way? There is a trivial sense in which we cannot. As an old Doris Day song reminds us, “Que sera, sera, whatever will be, will be.” This is a tautology – a truth about the meaning of words rather than an informative statement about the world. The consequence argument may also be tautological, though less obviously so. Let’s define determinism to mean that the state of the world at any given instant plus the laws of nature determine a unique future that leaves no other possibilities. What I think the consequence argument claims is that if determinism is true then the actualization of one possibility rather than another (say, avoiding rather than committing murder) is not up to us.
This is a clever argument, but it tells us only what follows logically from a particular definition of determinism. What we really want to know is whether the future is in fact unalterable. In particular, we want to discover whether possible occurrences in our personal futures can turn out just one way – whether they “Will be” or “May be.” How can we discover this?
Predictability & Liberty
Consider a new version of an old thought experiment. In this experiment Laplace’s demon is replaced by a supercomputer that can calculate what you will do by meticulously observing presents events and applying the laws of nature to them. To test this wonderful machine you ask it to tell you whether you will next move your right hand up or down. The computer says ‘down’; but then, just to defy its prediction, you move your hand up. The computer can’t win.
Even though it can calculate that you are going to defy its predictions, it can’t use that recognition to trump what you’re going to choose to do. As long as you know what it predicts you will do, it will be impossible for it to predict correctly whether you will move your hand up or down. A champion of the consequence argument might protest that this is because the experiment imposes a self-defeating constraint on the computer – namely, that the computer must tell you what it predicts you are going do before you do it. But determinism imposes a similar constraint on the universe. By rendering the universe intellectually friendly, determinism makes it possible in principle for us to infer the outcomes of causal chains, and so prevent some of those outcomes from happening in the same way as we can with the supercomputer.
...an advocate of the consequence argument might pounce on my words and declare that we mistakenly think we can alter the future only because we don’t have a broad or clear enough view of the chains of causes that bring that future about. “Scrooge,” that advocate might say, “assumes that his fate is up to him because he is focused on the probable outcome of his miserly ways, but his view is too narrow. There are a multitude of physical, physiological – remember the gravy – psychological and cultural causes that have brought him to this point in his life. But indeed, it is the minutely intricate successive states of the universe from one instant to the next that sweep him along in an iron progression to an unalterable future.”
This reply sounds better than it is. We have already acknowledged the limited scope of our ability to infer future events; but that does not settle the question of whether we are being swept along by the successive states of the universe to an unalterable future, or rather, whether we can alter the future by our choices.
Here are three reasons for doubting the deterministic argument that the future is in fact unalterable. First, Einstein showed that it is mistake to talk about ‘the state of the universe at a particular instant in time’. Newton was wrong, in that the countless processes going on in the universe are not synchronized. Experiments with extremely precise clocks have confirmed Einstein’s predictions that what time it is varies with relative speed and gravity. When you get off a plane you have aged a tiny bit less than the people waiting at the airport because they have been stuck in the airport while you were speeding toward them. A clock in your basement runs a tiny bit more slowly than a clock in your attic because gravity varies with distance from the Earth.
Second, very little that is happening in the universe affects the whole universe. Other than gravity and the inflation of space itself, the processes going on in the universe are local. Except for the strange case of quantum entanglements, events and processes do not affect one another unless they locally interact, like the gust of wind blowing the lobbed tennis ball. So there is no hard evidence that these processes together yield a unique universal future rather than a plurality of possible outcomes.
Third, biological evolution has produced organisms of astonishing complexity whose behavior is guided in part by their consciousness. Humans are a prime example. It remains unknown whether all of our conscious experiences, social interactions, and cultural practices can be reduced to physical brain events and so be fully explained by the laws that govern matter. Rather, the emergent realities of mental, social, and cultural life may very well in some ways constrain or control the very atoms that make their existence possible.
Determination & Control
The determinism supposed by the consequence argument asks us to believe that events of great social and cultural complexity, such as the writing of A Christmas Carol, or daily stock market fluctuations, are the inevitable consequences of the state of the universe and laws of nature after the Big Bang.
It asks us to believe that if time could be rolled back even to one second after the Big Bang, then history would unfold in exactly the same way, and all these events would occur again without the slightest variation. There can be no wiggle room in the iron block universe as it rolls forward. This is a lot to ask us to believe, and is far too speculative to be taken on faith. As far as we now know, it is just as likely that the past and present could have turned out differently than they did, and that the future that lies before us is alterable in important respects.
The extent of your responsibility for bringing about a future outcome depends both on causal agency (your making it happen) and motive (why you made it happen). Here I think the compatibilists offer the most plausible account. The more intentional, deliberate, and deeply anchored in your values and aspirations your chosen action is, the more the outcome you make happen is up to you.
There is no need to insert indeterminism into voluntary acts: the ‘will’ in free will depends on causality being operative when you do one thing rather than another. However, the ‘free’ in free will depends on your choice not being the unalterable outcome of causal chains that extend from the remote past. In other words, your freedom depends on there being times in your life when the acts you end up doing are open possibilities; and as you look to the future you can infer other open possibilities, both acts and outcomes of acts, and alter your actions in an ongoing endeavor to actualize your values and aspirations.
So it seems to me that Scrooge (and Dickens) got it right. He bets that his terrifying visions of the future are the “shadows of things that May be” rather than the “shadows of the things that Will be.” Although Scrooge cannot be sure this is true, he recognizes that he cannot change the end toward which the course of his life is leading unless it is true.
Perhaps science will someday confirm the openness of future possibilities in ways relevant to human choice. In the meantime, it is instructive to consider that if we have free will, it is probably the free will of Ebenezer Scrooge.
Compatibilism is the idea that there is no conflict between determinism and free will. Incompatibilism is the idea that free will cannot exist in a deterministic universe. There's been a lot of discussion over which view is correct. What's remarkable about the debate isn't so much the stubbornness or passion which has been exhibited by this or that party, but the fact that the very terms of the debate are controversial.
There is a great deal of confusion about what the key issues in the debate are and how we should be talking about them. As a result, there is a meta-debate within the debate itself. You cannot engage in the debate without also engaging in a debate about the debate--about what issues are at stake and about how the issues should be framed.
So here's what I want to do: I want to explain why I think incompatibilists are doing a very bad job of framing the debate, and also why compatibilism is the most reasonable option on the table. It's an ambitious project, and I don't expect to win over many audiences with my arguments. But I do hope to stimulate a bit of critical reflection and perhaps help guide others towards a more fruitful way of thinking about the issues.
