Many people seem to believe that morality depends for its existence on a metaphysical quantity called “free will.” This conviction is occasionally expressed—often with great impatience, smugness, or piety—with the words, “ought implies can.” Like much else in philosophy that is too easily remembered (e.g. “you can’t get an ought from an is.”), this phrase has become an impediment to clear thinking.

In fact, the concept of free will is a non-starter, both philosophically and scientifically. There is simply no description of mental and physical causation that allows for this freedom that we habitually claim for ourselves and ascribe to others. Understanding this would alter our view of morality in some respects, but it wouldn’t destroy the distinction between right and wrong, or good and evil.

The following post has been adapted from my discussion of this topic in The Moral Landscape (pp. 102-110):

We are conscious of only a tiny fraction of the information that our brains process in each moment. While we continually notice changes in our experience—in thought, mood, perception, behavior, etc.—we are utterly unaware of the neural events that produce these changes. In fact, by merely glancing at your face or listening to your tone of voice, others are often more aware of your internal states and motivations than you are. And yet most of us still feel that we are the authors of our own thoughts and actions.

The problem is that no account of causality leaves room for free will—thoughts, moods, and desires of every sort simply spring into view—and move us, or fail to move us, for reasons that are, from a subjective point of view, perfectly inscrutable. Why did I use the term “inscrutable” in the previous sentence? I must confess that I do not know. Was I free to do otherwise? What could such a claim possibly mean? Why, after all, didn’t the word “opaque” come to mind? Well, it just didn’t—and now that it vies for a place on the page, I find that I am still partial to my original choice. Am I free with respect to this preference? Am I free to feel that “opaque” is the better word, when I just do not feel that it is the better word? Am I free to change my mind? Of course not. It can only change me.

There is a distinction between voluntary and involuntary actions, of course, but it does nothing to support the common idea of free will (nor does it depend upon it). The former are associated with felt intentions (desires, goals, expectations, etc.) while the latter are not. All of the conventional distinctions we like to make between degrees of intent—from the bizarre neurological complaint of alien hand syndrome to the premeditated actions of a sniper—can be maintained: for they simply describe what else was arising in the mind at the time an action occurred. A voluntary action is accompanied by the felt intention to carry it out, while an involuntary action isn’t. Where our intentions themselves come from, however, and what determines their character in every instant, remains perfectly mysterious in subjective terms. Our sense of free will arises from a failure to appreciate this fact: we do not know what we will intend to do until the intention itself arises. To see this is to realize that you are not the author of your thoughts and actions in the way that people generally suppose. This insight does not make social and political freedom any less important, however. The freedom to do what one intends, and not to do otherwise, is no less valuable than it ever was.

While all of this can sound very abstract, it is important to realize that the question of free will is no mere curio of philosophy seminars. A belief in free will underwrites both the religious notion of “sin” and our enduring commitment to retributive justice. The Supreme Court has called free will a “universal and persistent” foundation for our system of law, distinct from “a deterministic view of human conduct that is inconsistent with the underlying precepts of our criminal justice system” (United States v. Grayson, 1978). Any scientific developments that threatened our notion of free will would seem to put the ethics of punishing people for their bad behavior in question.

The great worry is that any honest discussion of the underlying causes of human behavior seems to erode the notion of moral responsibility. If we view people as neuronal weather patterns, how can we coherently speak about morality? And if we remain committed to seeing people as people, some who can be reasoned with and some who cannot, it seems that we must find some notion of personal responsibility that fits the facts.

Happily, we can. What does it really mean to take responsibility for an action? For instance, yesterday I went to the market; as it turns out, I was fully clothed, did not steal anything, and did not buy anchovies. To say that I was responsible for my behavior is simply to say that what I did was sufficiently in keeping with my thoughts, intentions, beliefs, and desires to be considered an extension of them. If, on the other hand, I had found myself standing in the market naked, intent upon stealing as many tins of anchovies as I could carry, this behavior would be totally out of character; I would feel that I was not in my right mind, or that I was otherwise not responsible for my actions. Judgments of responsibility, therefore, depend upon the overall complexion of one’s mind, not on the metaphysics of mental cause and effect.

Consider the following examples of human violence:
1.A four-year-old boy was playing with his father’s gun and killed a young woman. The gun had been kept loaded and unsecured in a dresser drawer.
2.A twelve-year-old boy, who had been the victim of continuous physical and emotional abuse, took his father’s gun and intentionally shot and killed a young woman because she was teasing him.
3.A twenty-five-year-old man, who had been the victim of continuous abuse as a child, intentionally shot and killed his girlfriend because she left him for another man.
4.A twenty-five-year-old man, who had been raised by wonderful parents and never abused, intentionally shot and killed a young woman he had never met “just for the fun of it.”
5.A twenty-five-year-old man, who had been raised by wonderful parents and never abused, intentionally shot and killed a young woman he had never met “just for the fun of it.” An MRI of the man’s brain revealed a tumor the size of a golf ball in his medial prefrontal cortex (a region responsible for the control of emotion and behavioral impulses).

In each case a young woman has died, and in each case her death was the result of events arising in the brain of another human being. The degree of moral outrage we feel clearly depends on the background conditions described in each case. We suspect that a four-year-old child cannot truly intend to kill someone and that the intentions of a twelve-year-old do not run as deep as those of an adult. In both cases 1 and 2, we know that the brain of the killer has not fully matured and that all the responsibilities of personhood have not yet been conferred. The history of abuse and precipitating cause in example 3 seem to mitigate the man’s guilt: this was a crime of passion committed by a person who had himself suffered at the hands of others. In 4, we have no abuse, and the motive brands the perpetrator a psychopath. In 5, we appear to have the same psychopathic behavior and motive, but a brain tumor somehow changes the moral calculus entirely: given its location, it seems to divest the killer of all responsibility. How can we make sense of these gradations of moral blame when brains and their background influences are, in every case, and to exactly the same degree, the real cause of a woman’s death?

It seems to me that we need not have any illusions about a casual agent living within the human mind to condemn such a mind as unethical, negligent, or even evil, and therefore liable to occasion further harm. What we condemn in another person is the intention to do harm—and thus any condition or circumstance (e.g., accident, mental illness, youth) that makes it unlikely that a person could harbor such an intention would mitigate guilt, without any recourse to notions of free will. Likewise, degrees of guilt could be judged, as they are now, by reference to the facts of the case: the personality of the accused, his prior offenses, his patterns of association with others, his use of intoxicants, his confessed intentions with regard to the victim, etc. If a person’s actions seem to have been entirely out of character, this will influence our sense of the risk he now poses to others. If the accused appears unrepentant and anxious to kill again, we need entertain no notions of free will to consider him a danger to society.

Why is the conscious decision to do another person harm particularly blameworthy? Because consciousness is, among other things, the context in which our intentions become available to us. What we do subsequent to conscious planning tends to most fully reflect the global properties of our minds—our beliefs, desires, goals, prejudices, etc. If, after weeks of deliberation, library research, and debate with your friends, you still decide to kill the king—well, then killing the king really reflects the sort of person you are.

While viewing human beings as forces of nature does not prevent us from thinking in terms of moral responsibility, it does call the logic of retribution into question. Clearly, we need to build prisons for people who are intent upon harming others. But if we could incarcerate earthquakes and hurricanes for their crimes, we would build prisons for them as well. The men and women on death row have some combination of bad genes, bad parents, bad ideas, and bad luck—which of these quantities, exactly, were they responsible for? No human being stands as author to his own genes or his upbringing, and yet we have every reason to believe that these factors determine his character throughout life. Our system of justice should reflect our understanding that each of us could have been dealt a very different hand in life. In fact, it seems immoral not to recognize just how much luck is involved in morality itself.

Consider what would happen if we discovered a cure for human evil. Imagine, for the sake of argument, that every relevant change in the human brain can be made cheaply, painlessly, and safely. The cure for psychopathy can be put directly into the food supply like vitamin D. Evil is now nothing more than a nutritional deficiency.

If we imagine that a cure for evil exists, we can see that our retributive impulse is ethically flawed. Consider, for instance, the prospect of withholding the cure for evil from a murderer as part of his punishment. Would this make any sense at all? What could it possibly mean to say that a person deserves to have this treatment withheld? What if the treatment had been available prior to his crime? Would he still be responsible for his actions? It seems far more likely that those who had been aware of his case would be indicted for negligence. Would it make any sense at all to deny surgery to the man in example 5 as a punishment if we knew the brain tumor was the proximate cause of his violence? Of course not. The urge for retribution, therefore, seems to depend upon our not seeing the underlying causes of human behavior.

Despite our attachment to notions of free will, most us know that disorders of the brain can trump the best intentions of the mind. This shift in understanding represents progress toward a deeper, more consistent, and more compassionate view of our common humanity—and we should note that this is progress away from religious metaphysics. Few concepts have offered greater scope for human cruelty than the idea of an immortal soul that stands independent of all material influences, ranging from genes to economic systems. And yet one of the fears surrounding our progress in neuroscience is that this knowledge will dehumanize us.

Could thinking about the mind as the product of the physical brain diminish our compassion for one another? While it is reasonable to ask this question, it seems to me that, on balance, soul/body dualism has been the enemy of compassion. The moral stigma that still surrounds disorders of mood and cognition seems largely the result of viewing the mind as distinct from the brain. When the pancreas fails to produce insulin, there is no shame in taking synthetic insulin to compensate for its lost function. Many people do not feel the same way about regulating mood with antidepressants (for reasons that appear quite distinct from any concern about potential side effects). If this bias has diminished in recent years, it has been because of an increased appreciation of the brain as a physical organ.

However, the issue of retribution is a genuinely tricky one. In a fascinating article in The New Yorker, Jared Diamond writes of the high price we often pay for leaving vengeance to the state. He compares the experience of his friend Daniel, a New Guinea highlander, who avenged the death of a paternal uncle and felt exquisite relief, to the tragic experience of his late father-in-law, who had the opportunity to kill the man who murdered his family during the Holocaust but opted instead to turn him over to the police. After spending only a year in jail, the killer was released, and Diamond’s father-in-law spent the last sixty years of his life “tormented by regret and guilt.” While there is much to be said against the vendetta culture of the New Guinea Highlands, it is clear that the practice of taking vengeance answers to a common psychological need.

We are deeply disposed to perceive people as the authors of their actions, to hold them responsible for the wrongs they do us, and to feel that these debts must be repaid. Often, the only compensation that seems appropriate requires that the perpetrator of a crime suffer or forfeit his life. It remains to be seen how the best system of justice would steward these impulses. Clearly, a full account of the causes of human behavior should undermine our natural response to injustice, at least to some degree. It seems doubtful, for instance, that Diamond’s father-in- law would have suffered the same pangs of unrequited vengeance if his family had been trampled by an elephant or laid low by cholera. Similarly, we can expect that his regret would have been significantly eased if he had learned that his family’s killer had lived a flawlessly moral life until a virus began ravaging his medial prefrontal cortex.

It may be that a sham form of retribution could still be moral, if it led people to behave far better than they otherwise would. Whether it is useful to emphasize the punishment of certain criminals—rather than their containment or rehabilitation—is a question for social and psychological science. But it seems clear that a desire for retribution, based upon the idea that each person is the free author of his thoughts and actions, rests on a cognitive and emotional illusion—and perpetuates a moral one.

So many books....I was rereading Harris's "The End of Faith," hoping to recapture some of my exhilaration at the first reading, and I found myself thinking, "Man, this is pretty shallow" about half way through.  I weep.
Thanks so much John. You know I nearly didn't post this because I was worried that I was doing it improperly by not just posting a link, but then I said fuck it, most people if they see a link don't even bother, and then who is going to read this wonderful little article? I really appreciate your comment, which in turn reminds me that there are some sensible folks out there, some who actually are open enough to change their mind on something when faced with new information. Thanks again!
And to make your point for you, the topic currently underneath this one is titled "Atheistic Satanists". ROTFL!!!
To suggest that my father who died of Alzheimer's had, in his last years, anything like free will is absurd, as absurd as it is to suggest that I have free will.  Either there is cause and effect, or there is not.  Either there is a "god"™ who knows the future, or there is not.

Free will is a fairytale we tell ourselves so that we can ignore the bondage of our existence...kind of like god. The universe is causal, meaning every effect has a cause, and it is deterministic, meaning that the causes and effects can be broken down into fundamental laws. We will never know these laws, although we will contue to make finer and finer estimates of them, but the logical result of their consideration is that everything happening in the universe was set in motion and determined with the universe itself. I'm not responsible for that, and neither are you, so we are not responsible for anything we are doing now because our actions are only the effects of prior causes that could not have happened any other way.


No free will. No choice. No morality. No good. No bad. No right. No wrong.



I seek the nothing, the calm, the still

But I am moved against my will.

I am trapped outside my dreams,

And cannot be no thing, it seems.

The Moral landscape is next on my plie to read.

So I will refrain from commenting at the moment, but your post has got me thinking!!

Question - your profile picture made me smile........from my motherland!!

Answer: I am forced to admit my ignorance. I saw this picture posted elsewhere on here and, feeling I needed a change from the picture of Aristotle I had been using up until then, stole the picture as my own. I just thought it was beautiful, I have no idea what it is or where it (or you) are from. Care to relieve me of my ignorance?
A quick look at your profile reveals New Zealand to be the fantastic locale in question. That's as far as I've got.


I now live near Nelson in the south island of NZ...a nice place. Only been in NZ 3 years, originally from the UK and your profile picture immediately reminded me of the homeland, dark gritsone hills and atmospheric sky. I think the picture is from the Saddlworth Moors area in the North of UK, about an hour or so from were I originated.

Not sure how religious NZ is, although there seems to be alot of churches, but the Kiwis generally seem pretty laid back.

Enjoyed your original post.

Regards, Sean

Thanks for posting this.

I am currently trying to sort out what is meant by 'free will' when people use the term. I do find myself struggling with the idea that whatever anyone does, they were helpless to do otherwise and therefore should be forgiven of whatever they do. Then, how can one non-free person rehabilitate another non-free person (unless of course the rehabilitator is helpless to do otherwise....?) What is the mechanism that makes the rehabilitation effective?

A further question of ethics for me is: why does a society need to invest time and resources into trying to rehabilitate all non-free "offenders" regardless of the depth of their anti-social environmental programming? Is there science-based evidence that this can be done? Do we really know how many "contact hours" a psychopath needs to have with therapists to be even partially rehabilitated?

We easily justify executing an "anti-social" bear or wild cat "before someone else gets hurt". It isn't retribution or meant as a deterrent to other bears.  It is resource management.


(I am already wincing at the flame storm this post will trigger...)

Not at all, thanks for the interesting response. I'll give you my take on things. I take an organismic approach, which means a few things, but basically the idea is that organisms (groups) of any size succeed simply on naturalistic terms: whether they have enough power, motivation, etc. to overcome the obstacles it faces from the environment, competition with other organisms, etc. If you grant me that a social group behaves in just the same way as individual organisms, then all the same rules apply. The organism (individual or group) is healthy when it is motivated towards adaptive behaviors, and vice versa, so 1. the same mechanisms of rehabilitation are operating on the group as well as the individual. Just as we are made "good" individuals by being both internally operational (all our organs working harmoniously towards the health of the individual) and externally operational (working with others harmoniously towards mutual goals), a group of people is made "good" by having internal harmony and also being capable of cooperation with still other groups (when you get to the level of all humanity, I guess we are just one super-organism which itself can aim towards cooperation with all life on the planet, and beyond!). In other words, if an organism is lucky enough to be directed towards/motivated towards adaptive behavior, it already possesses what it needs to redirect enough of its member parts towards the goals of the entire organism. Otherwise the offending part is "lost" and the organism does well to find ways of expelling it.


2. I don't believe that there is necessarily a way to reform all people who are simply victims of their environment, so I agree with you that it becomes a matter of resource management for any given organism/social group. Even if it were possible, it might not be economically feasible, and the organism would still be justified, i.e. it would still be in its best interests, to "cut off" resources to the offenders. Whether a person is made offensive/sociopathic purely by negative nurture inputs or purely by negative nature inputs or by some combination thereof isn't important, it becomes important only whether it is possible to rehabilitate them and whether the cost of doing so outweighs the benefits of doing so (at which point we must delve into questions about what a person's "worth" is to a society, which is itself a fascinating question).


3. On all organismic levels then, the only questions are whether the members are properly motivated, or whether they are gifted with (sorry for the semi-religious connotation of such phrases) the necessary powers for living well. One group may have enough motivation/power to send some of its members into action to turn more of its malfunctioning parts into functioning parts, where another group simply may not have it in them. I would expect that the same processes of evolution would take place, and the groups better suited to its environment would manage to strike the proper balance between investing resources towards rehabilitation, sequestration, or simple tolerance of its malfunctioning parts. I think anyone who resorts to proclaiming that another person acted malevolently out of their "free will" and therefore is deserving of whatever punishment they have concocted is simply justifying their own perfectly natural organismic impulses to expel offensive behavior with an ultimately meaningless device, and they have not been capable of thinking things out in a purely naturalistic way. I am only left to wonder whether there is enough motivation present to reveal the nature of reality to such people so that they too might be rehabilitated of their nonsensical (and ultimately maladaptive) beliefs.


Sorry that was so long, it is almost 2 am... whew! And sorry for all the editing too!



"I do find myself struggling with the idea that whatever anyone does, they were helpless to do otherwise and therefore should be forgiven of whatever they do."


First, the terminology of "helpless to do otherwise" is not a very helpful one: that makes it sound as if the person is not acting in accordance with what they will. They absolutely are (usually), it's just that what they will is ultimately going to be the sum total of a large amount of antecedent factors.

People suffering from alien hand syndrome are helpless, because they literally cannot help do these involuntary movements, regardless of their will or what they consciously want to do. An indoctrinated soldier who kills someone he is taught to hate is not helpless in the same way, because he is doing what he wants to do.

All determinism says is that in both cases, what they ultimately want is going to be the sum total of a lot of antecedent factors. People still can and do act in accordance with their will.


"Then, how can one non-free person rehabilitate another non-free person (unless of course the rehabilitator is helpless to do otherwise....?) What is the mechanism that makes the rehabilitation effective?"


I find that a fairly short-sighted question. It's just not that complicated.

We're able to condition dogs quite well, we're able to teach children how to behave, etcetera... we can start thinking very philosophically about how miraculous it is that we can do this and how it could be possibly that we can change a dog's instinctual patterns and change them to something else... but in practice we know that this can be done (to an extent). We do it all the time.


"A further question of ethics for me is: why does a society need to invest time and resources into trying to rehabilitate all non-free "offenders" regardless of the depth of their anti-social environmental programming? Is there science-based evidence that this can be done?"


I'd say we don't have the data to answer that question. The idea that people have free will is a common (and probably innate one) and so punishment has always largely been focused on retribution and revenge. We've only very recently started to realise that the picture is not quite that simple, and people don't have this contra-causal magical component that retributionism assumes.

Because of this, research into how best to rehabilitate prisoners and criminals is meager at best. We just don't know how effective it is, to what extent it works, with who it can work and who it can't be, etcetera. Perhaps it will indeed turn out that people are unchangeable and that you can't "reprogram" people from criminal environments (unlikely though); in this case, we would have to think about isolating these people... but even in that case it's not going to be done with a revenge attitude in mind. It's going to be about protecting us, not taking revenge on them.

But we just don't know what the right alternative is yet. But I think we have a clear moral obligation to find out.
