XXIII. It Depends On What You Mean By "Free Will"--And What You Do With It

[Warning: Another lengthy treatment of an elusive reality. Fair treatment denies brevity, I say. But there is also the matter of how much appetite and patience you have for such topics.]

From the Chronicle Review (of the Chronicle of Higher Education):
Free will has long been a fraught concept among philosophers and theologians. Now neuroscience is entering the fray. 
For centuries, the idea that we are the authors of our own actions, beliefs, and desires has remained central to our sense of self. We choose whom to love, what thoughts to think, which impulses to resist. Or do we? 
Neuroscience suggests something else. We are biochemical puppets, swayed by forces beyond our conscious control. So says Sam Harris, author of the new book, Free Will (Simon & Schuster), a broadside against the notion that we are in control of our own thoughts and actions. Harris's polemic arrives on the heels of Michael S. Gazzaniga's Who's In Charge? Free Will and the Science of the Brain (HarperCollins), and David Eagleman's Incognito: The Secret Lives of the Brain (Pantheon), both provocative forays into a debate that has in recent months spilled out onto op-ed and magazine pages, and countless blogs. 
What's at stake? Just about everything: morality, law, religion, our understanding of accountability and personal accomplishment, even what it means to be human. Harris predicts that a declaration by the scientific community that free will is an illusion would set off "a culture war far more belligerent than the one that has been waged on the subject of evolution." 
---"Is Free Will an Illusion?" The Chronicle Review (3.18.12)
And don't forget the folks most recently studying the genome (which prescribes those neurological, biochemical processes), or the classical and operant conditioning folks, the last-generation students of learning, behavior and acculturation. All have had their reasons and their proofs why so many of our behaviors, including thinking, preferences and choices, are a function of genetic prescriptions or predispositions, or what in one way or another is conditioned or learned in our cultural, social environment. As individuals and as communities, can we work at all well with the notion that an array of deterministic forces render us more complex, but self-deceiving automatons than crafters and directors of our own destiny?

Let's take a look at some excerpts from those recent articles, and try to sort out what neuroscience now adds to this dialogue--and what remains of notions or experience of freedom of thought, choice and behavior. Or does it all depend on what we mean by "free will," the nature, context and focus of the inquiry, the purposes and designs for its conclusions and applications? Of course, I have some thoughts on the subject which I will offer at the end.

First, from Jerry A. Coyne, a professor in the department of ecology and evolution at the University of Chicago:
The term "free will" has so many diverse connotations that I'm obliged to define it before I explain why we don't have it. I construe free will the way I think most people do: At the moment when you have to decide among alternatives, you have free will if you could have chosen otherwise. To put it more technically, if you could rerun the tape of your life up to the moment you make a choice, with every aspect of the universe configured identically, free will means that your choice could have been different. [But there are other meaningful conceptual understandings and definitions of "free will." GH] 
That's one clear, direct point of view, even if it does not deal with the alternative arguments or views sufficiently. Next is Alfred R. Mele, a professor of philosophy at Florida State University. He is the director of Big Questions in Free Will, an investigation of the science, philosophy, and theology of free will, supported by a $4.4-million grant from the John Templeton Foundation.
Is free will an illusion? Recent scientific arguments for an affirmative answer have a simple structure. First, data are offered in support of some striking empirical proposition—for example, that conscious intentions never play any role in producing corresponding actions. Then this proposition is linked to a statement about what free will means to yield the conclusion that it does not exist. [As in the first essay. GH] 
In my book Effective Intentions: The Power of Conscious Will (Oxford University Press, 2009), I explain why the data do not justify such arguments. Sometimes I am told that even if I am correct, I overlook the best scientific argument for the nonexistence of free will. This claim, in a nutshell, has two parts: Free will depends on the activity of nonphysical minds or souls, and scientists have shown that something physical—the brain—is doing all the work. 
As the majority of philosophers understand the concept, free will doesn't depend at all on the existence of nonphysical minds or souls. But philosophers don't own this expression. If anyone owns it, people in general do. So I conducted some simple studies. 
In one, I invited participants to imagine a scenario in which scientists had proved that everything in the universe is physical and that what we refer to as a "mind" is actually a brain at work. In this scenario, a man sees a $20 bill fall from a stranger's pocket, considers returning it, and decides to keep it. Asked whether he had free will when he made that decision, 73 percent answer yes. This study suggests that a majority of people do not see having a nonphysical mind or soul as a requirement for free will. [Is that satisfactorily proved by this study uncontrolled for whether the participants have fully accepted and internalized the notion that brain equals mind completely? GH] 
If free will does not depend on souls, what is the scientific evidence that it is an illusion? I'll briefly discuss just one study. Chun Siong Soon and colleagues, in a 2008 Nature Neuroscience article, report the results of an experiment in which participants were asked to make simple decisions while their brain activity was measured using functional magnetic resonance imaging, or fMRI. The options were always two buttons, and nothing hinged on which was pressed. Soon and coauthors write: "We found that two brain regions encoded with high accuracy whether the subject was about to choose the left or right response prior to the conscious decision," noting that "the predictive neural information preceded the conscious motor decision by up to 10 seconds." The science writer Elsa Youngsteadt represented these results as suggesting that "the unconscious brain calls the shots, making free will an illusory afterthought." 
In this study, however, the predictions are accurate only 60 percent of the time. Using a coin, I can predict with 50-percent accuracy which button a participant will press next. And if the person agrees not to press a button for a minute (or an hour), I can make my predictions a minute (or an hour) in advance. I come out 10 points worse in accuracy, but I win big in terms of time. 
So what is indicated by the neural activity that Soon and colleagues measured? My money is on a slight unconscious bias toward a particular button—a bias that may give the participant about a 60-percent chance of pressing that button next.
Given such flimsy evidence, I do not recommend betting the farm on the nonexistence of free will. 
---"The Case Against the Case Against Free Will," by Alfred R/ Mele, The Chronicle Review (3.18.12)
There appears more than enough flimsy evidence to go around in that point of view. Next up is Michael S. Gazzaniga, director of the SAGE Center for the Study of the Mind at the University of California at Santa Barbara. He is the author, most recently, of Who's In Charge? Free Will and the Science of the Brain (HarperCollins, 2011).
The exquisite machine that generates our mental life also lives in a social world and develops rules for living within a social network. For the social network to function, each person assigns each other person responsibility for his or her actions. There are rules for traffic that exist and are only understood and adopted when cars interact. It is the same for human interactions. Just as we would not try to understand traffic by studying the mechanics of cars, we should not try to understand brains to understand the idea of responsibility. Responsibility exists at a different level of organization: the social level, not in our determined brains. 
Viewing the age-old question of free will in this framework has many implications. Holding people responsible for their actions remains untouched and intact since that is a value granted by society. We all learn and obey rules, both personal and social. Following social rules, as they say, is part of our DNA. Virtually every human can follow rules no matter what mental state he or she is in. 
[...] We should hold people responsible for their actions. No excuses. That keeps everything simple and clean. Once accountability is established, we can then take up the more challenging questions of what as a society we should do about someone engaged in wrongdoing. We can debate punishment, treatment, isolation, or many other ways to enforce accountability in a social network. Those are truly difficult issues. Establishing how to think about responsibility is not. 
---"Free Will is an Illusion, but You're Still Responsible for Your Actions," by Michael S. Gazzaniga, The Chronicle Review (3.18.12)
Okay, that one was more about the notion of personal responsibility assuming the neuroscientist are right than the reasons why they are; but a conversation worth having. Next is Hilary Bok, an associate professor of philosophy at the Johns Hopkins University. She is the author of Freedom and Responsibility (Princeton University Press, 1998).
Whether this view provides an adequate account of free will is not a problem neuroscience can solve. Neuroscience can explain what happens in our brains: how we perceive and think, how we weigh conflicting considerations and make choices, and so forth. But the question of whether freedom and moral responsibility are compatible with free will is not a scientific one, and we should not expect scientists to answer it. [Ah, but that very statement is very much at the heart of the different understandings of the questions, context, methodologies, purposes and implications. GH] 
Whatever their views on the compatibility of freedom and determinism, most philosophers agree that someone can be free only if she can make a reasoned choice among various alternatives, and act on her decision; in short, only if she has the capacity for self-government. 
Neuroscience can help us to understand what this capacity is and how it can be strengthened. What, for instance, determines when we engage in conscious self-regulation, and how might we ensure that we do so when we need to? If the exercise of self-government can deplete our capacity for further self-government in the short run, what exactly is depleted, and how might we compensate for its loss? Does self-government deplete our resources in the short run while strengthening them over time, like physical exercise, or does it simply weaken our ability to govern ourselves without any compensating benefit? 
Neuroscience can answer those questions, and it can provide causal explanations of human action, but it can't resolve the question of whether or not such explanations are compatible with free will. 
---"Want to Understand Free Will? Don't Look to Neuroscience," by Hilary Bok, The Chronicle Review (3.18.12)
Not bad; not adequately responsive to the points of the scientists, but relevant and worthy considerations. Not bad. Next, Owen D. Jones, a professor of law and biological sciences at Vanderbilt University. His book Law and Neuroscience, with Jeffrey Schall and Francis Shen, is forthcoming from Aspen Publishers next year.
Well, his frustration with the overworked and redundant arguments in the discussion quickly give way to furthering the arguments in the discussion--and advance the discussion very well he does. Now last, the estimable and entertaining Paul Bloom, a professor of psychology and cognitive science at Yale University. His next book, Just Babies: The Origins of Good and Evil, will be published next year by Crown.
I and my views find more compatiblity and comfort with Mr. Bloom and his take on it all. But, as threatened, I reserve the last word for myself. Since a good friend finds it irksome when I use pullquotes from something I've written before, here I will just share with you some long-held views, although you will find very similar ideas and language, but more of it, in two pieces called "Choices"  and "The Limits of Merit & Choice" written by someone or other some years ago.

Your freedom and choices, it appears, may be more limited than you think. What remains to you is the constant drumbeat of scholarly research that informs us we are each bound in our own Procrustean bed, genetically-defined, fixed more-or-less, and further limited by the environments we were reared in and live in.

That unwelcome, deterministic reality is an earnest finger poked in our chest, demanding to be heard, attesting repeatedly to the inherited and conditioned responses and qualities that characterize what we do, what we think, who we are. A more euphemistic sentiment might allude to the limits and conditions on the freedom of man. A more direct and fatalistic disposition might charge that what the genes don't dictate, the environment will. And if the genetic brand of determinism is incomprehensible or unacceptable to you, don't expect to find more comfort in the world of conditioned behavior and beliefs. Or do you believe that the realities of family and cultural conditioning are any less powerful than your genetic endowment?

So do not deceive yourself or be deceived. The power of our genetic endowment and the behavioral conditioning of our environment are great indeed. With compelling research in hand, science would reasonably advise you that your very personality and many of your personal traits and predilections are influenced significantly by your genes. So is your predisposition to pursue certain types of vocations or interests, or fall prey to certain illnesses or diseases. And the ubiquitous power of the environment, the impact of family and culture as explained by the learning and conditioning sciences, has been well understood much longer.

Of course, many are simply in denial. They would wish it all away, dismiss it as exaggerated in impact and import. But that's a fool's errand, whether born of intellectual ignorance, emotional defensiveness, or worse, a stiff-necked, misguided mission to carry water for various ideological, religious or social agendas. They greatly underestimate the near uncontrollable, deterministic power of genetic inheritance and environmental conditioning. But operating under a self-constructed illusion of freedom—denying, distorting or reshaping the truth—has never been the right answer, or even a workable answer. Then you are working with a lie, and have no chance at all.

You might well conclude, then, that the natural condition of man is an utter lack of freedom, the absence of real, voluntary personal choices—or, put another way, that any sense of freedom exists only in ignorance.

Moving Toward a Reality of Freedom

If all this is just too emotionally confining and personally limiting, too threatening to your notion of freedom and identity, potential and possibilities—it should be. Oh, it's not that this is all bad science, a cruel, controlling hoax, a lie. No, in large part it is too true. And the only real uncertainty is how large a part each factor plays in influencing the understanding of our alternatives and the making of our choices. But it isn't as bleak as it sounds.

In a real sense, you can enjoy and exercise more real freedom. Your freedom is first in knowing what has made you who you are, the way you are—and how. You can better understand your genetic predispositions and prescriptions; more is being learned about such things every day, and you can have your genetic endowment examined and explained to you for a reasonable price at commercial providers of such services.

It is also in knowing how your family and cultural environment has shaped you, conditioned you, to be who you are, the way you are. You can learn more about such processes, which makes alternatives more real--the potential effect on you of different places and people, different thinking and ways of doing things. Your freedom is in that knowledge. You can also read what different people are reading, listen for what they are saying, watch for what they are doing. In this way you can learn more about what you need to know, and better understand.

You can, then, see yourself and others in a different, more interdependent way, a more understanding and sympathetic way. And to the extent you know the ways you and others are a product of your changeable circumstances—family, culture, your time and place, the box you are in—you have a blueprint for personal change.

You can have real alternatives and choices to make. And you can have better-informed reasons to believe in and make your choices. If there is anything more to your notion of freedom than a hollow log, you can know that there are better choices you can make, actions you can take, to access better opportunities to grow—or not.

And the scope of the alternatives you entertain and understand, and the particular choices you pursue with understanding, also define your freedom, don't they? A choice to refrain from expanding your experience, knowledge or ability is, in effect, a choice to limit or deny your future choices—and therefore the future scope of your freedom. So it is also with choices to indulge foolish, anti-social or base desires and emotions. They can threaten life or health, result in imprisonment or legal limitations, or compromise your honor, trustworthiness, or self-esteem in ways that limit your future relationships and opportunities. These acts, too, limit your future choices and freedom. And they can be better controlled.

So, you can plan your way toward readiness to take the first steps out of the behavioral box you're in. You can plan your way to choosing better alternatives and expand your possibilities, that they are real and waiting for you—even calling you.

Move, literally. Change the physical place you are in and the people around you. Seek people and situations that will expect more of what you want to expect of yourself. They can notably change your actions, what you do, change your thinking, and to some extent, who you are. And the more you know about yourself—about those influencing factors—the more readily, competently you will make choices for effective change in your life. And yes, that honest knowledge will also have to acknowledge your limitations as well as your potential. That's important, too. But, most often, there will be some better alternatives, some better choices.

Please make some choices that work for other people, too—people you probably don't know or don't know well. To one extent or another, you share with them some of the same space, even if not the same experiential boxes. Make some choices for tolerance or, better still, acceptance and civility. Or, go crazy: think about respect and caring and serving.

Make some choices for community and your best contribution to it. Consider more charitably the poor, the immigrant, the stranger, the prisoner. Consider again issues of access to education and health care, and stewardship of our environment. Be part of solutions, not problems; building up, not tearing down; caring, not neglecting or, worse still, hating. You can do this. But you need to embrace a new sense of responsibility, some knowledge of the alternatives and possibilities—your possibilities. And you have to make some choices.

The Limits of Merit & Choice

Now, let's take a look at another application in the broad arena of social policy that begs for understanding of these deterministic forces in the lives of individuals and groups of people. It's about how ignorance about such things, or unwillingness to understand, leads us embrace social half-truths that harm us more than help us, both as individuals and as a society.

It's not a fabrication, a lie. It's just not the whole truth. And the part that's been omitted—or is it just ignored?—should provide the basis for us to consider providing better for those most in need. I'm speaking of our unwarranted overemphasis on personal merit and, as we've discussed elsewhere, freedom of choice.

It really does appeal to us, all of us. It panders to our self-esteem, our sense of self-determination and self-sufficiency, our self-congratulatory tendencies. We want to believe that we earned what we have—that we pulled ourselves up by our bootstraps, mapped out our plans, prepared ourselves, then worked hard, harder than the next guy, earning our way to our definition of success. And in a very real, experiential sense, it is true. (Most of us feel that's exactly what we've done!)

We also want to believe that it's not our fault if the next guy wasn't as ambitious, didn't prepare himself as well, didn't work as hard, wasn't as able. It's not our fault if he was too lazy or irresponsible, lacked discipline, character or interpersonal capability. It's not our fault if he wasn't intelligent, talented or savvy enough. It's not our fault if he was too different, unstable or disabled. We each get what we earn, what we deserve. (Isn't that right?)

And what of the poor, the competitive failures of whatever stripe? Why, they just suffer the natural consequences of their own failings and failure. And that's not our fault, either. How could it be? (So, why should it be our responsibility?)

Of course it's not your fault or mine—at least not most of the time. But most often, neither is it theirs. Notably, in a most real sense, most often we are no more the author of our successes than they are of their failures. Heresy, indeed! But let me briefly explain why, in more empirical terms, this is also true.

You understand the continuing discussion and research about nature and nurture, of course. We discussed it in Choices. You're familiar with the debate about how much of the way we are is the result of the genetic legacy of our parents and forbears, and how much is the result of the way we are conditioned and schooled, what we learn in our families, communities and cultures. What is not in doubt is that the combination of our genes, family, culture and education determines who we are, how we act, and the likely limits of our potential and achievements. And if most everyone still has some alternatives, some choices, those afforded the least able of our brethren, the least fortunate, are so many fewer and so much narrower, and their ability to act on them is so much less. 

The irony is that we discuss it, make casual affirming observations about it in everyday life, even ponder it with personal satisfaction or dismay, but then go about our lives dealing with each other, making personal and organizational decisions and crafting public policy as though we didn't know it or didn't believe it. The truth is that the power and perceived importance of our public, cultural half-myths trump what we instinctively know and what science more resoundingly than ever confirms. The truth is inconvenient and unwelcome to our sense of independence, accomplishment and self worth. It can coexist only uncomfortably with those cultural values.

So, just how right, how defensible, then, is that laissez-faire foundation on which we stand? How fair or egalitarian, how ethical and moral, how humane and intelligent are our assumptions about getting what we earn or deserve? How even is the playing field, how just the result? Is it not true that there, but for the deal of the genetic cards, the spin of the birth-place roulette, go I—dross in the crucible of our competitive society, failed or failing, and much in need of the help and support of my community, my more fortunate brethren? Shouldn't the integrity of an accountable, civilized society demand a full understanding and honest acknowledgment of this reality? Wouldn't it respond honestly, responsibly, and effectively to the needs of the innocent poor, infirm and unable? Wouldn't health care, education, and subsistence living be their right as it would everyone's?

(My Christian faith informs me that we are each just who God intended us to be based on the dictates of our singular spiritual paths, and the genetic endowment and life circumstances that deliver us there. And more, we have responsibilities and accountabilities for one another. That is the signal characteristic of faith community, and any real community. No one left behind.)
