Dennett Willing to Abandon the term "Free Will"?

By Greg Caruso
Flickers of Freedom Blog
Originally posted March 19, 2014

Here is an excerpt:

But recently I have learned from discussions with a variety of scientists and other non-philosophers (e.g., the scientists participating with me in the Sean Carroll workshop on the future of naturalism) that they lean the other way: free will, in their view, is obviously incompatible with naturalism, with determinism, and very likely incoherent against any background, so they cheerfully insist that of course they don’t have free will, couldn’t have free will, but so what? It has nothing to do with morality or the meaning of life. Their advice to me at the symposium was simple: recast my pressing question as whether naturalism (materialism, determinism, science...) has any implications for what we may call moral competence. For instance, does neuroscience show that we cannot be responsible for our choices, cannot justifiably be praised or blamed, rewarded or punished? Abandon the term “free will” to the libertarians and other incompatibilists, who can pursue their fantasies untroubled. - See more at:

Experimental Approaches to Free Will: Knobe and Nahmias

Joshuan Knobe and Eddy Nahmias

Knobe and Nahmias begin with an overview of the early history and aims of experimental philosophy. Then they discuss experiments on the contrast between bypassing and throughpassing intuitions about free will (8:57); Nahmias’s “theory lite view,” according to which ordinary people have no strong views about the relation between mind and brain (17:34); whether the folk have a causal or an interventionist view of agency (24:17); the effect of descriptions of determinism on folk intuitions (32:52); and Nahmias’s work on “willusionism,” inspired by his critical view of certain popularized versions of free-will skepticism (41:47). Finally, Knobe and Nahmias consider future results that could resolve some of their disagreements (48:49) and forecast the next big steps in experimental philosophy of free will (57:00).

Book Review: Does rationality + consciousness = free will?

Review of Rationality + Consciousness = Free Will
by David Hodgson. New York: Oxford University Press

Review by Brian Earp

Do we have free will or don’t we? Or do we have it in degrees? Is free will compatible with determinism or is it not? What about indeterminism? David Hodgson is not the first to explore this thicket. Following the advice of Hobbes, the first step in any effort to answer such questions should be to pose another set of questions: What do you mean by “free”? By “we”? By “have”and “will”? What is your notion of “compatible” and “incompatible”? How do you define“determinism”? And so on through the list of very pregnant turns-of-phrase.

In his latest book, Hodgson does somewhat less to “examine the Definitions of former Authors”than to “make them himself.” Though he does give some broad gestures at foundational texts in the opening chapters of his work, and while he sprinkles some references to his contemporaries throughout, Hodgson spends the bulk of his time developing his own distinctive account. Let us try to make some sense, then, of what that account is saying.

The War on Reason

Scientists and philosophers argue that human beings are little more than puppets of their biochemistry. Here's why they're wrong.

By Paul Bloom
The Atlantic 
Originally posted on February 19, 2014

Aristotle’s definition of man as a rational animal has recently taken quite a beating.

Part of the attack comes from neuroscience. Pretty, multicolored fMRI maps make clear that our mental lives can be observed in the activity of our neurons, and we’ve made considerable progress in reading someone’s thoughts by looking at those maps. It’s clear, too, that damage to the brain can impair the most-intimate aspects of ourselves, such as the capacity to make moral judgments or to inhibit bad actions. To some scholars, the neural basis of mental life suggests that rational deliberation and free choice are illusions. Because our thoughts and actions are the products of our brains, and because what our brains do is determined by the physical state of the world and the laws of physics—perhaps with a dash of quantum randomness in the mix—there seems to be no room for choice. As the author and neuroscientist Sam Harris has put it, we are “biochemical puppets.”

Free Will Does Not Exist. So What?

By Paul Bloom
The Chronicle of Higher Education
Originally posted March 18, 2012

Here is an excerpt:

This is what many call free will, and most scientists and philosophers agree that it is an illusion. Our actions are in fact literally predestined, determined by the laws of physics, the state of the universe, long before we were born, and, perhaps, by random events at the quantum level. We chose none of this, and so free will does not exist.

I agree with the consensus, but it's not the big news that many of my colleagues seem to think it is. For one thing, it isn't news at all. Determinism has been part of Philosophy 101 for quite a while now, and arguments against free will were around centuries before we knew anything about genes or neurons. It's long been a concern in theology; Moses Maimonides, in the 1100s, phrased the problem in terms of divine omniscience: If God already knows what you will do, how could you be free to choose?

More important, it's not clear what difference it makes.

Static and dynamic metaphysics of free will: A pragmatic perspective

By Eric Racine
The Neuroethics Blog
Originally posted January 14, 2014

In the public eye, one of the most striking types of findings neuroscience research claims to unravel concerns how decisions are made and whether these decisions are made “freely”. Unpacking the relationship between what is meant by “freely” and other neighboring notions such as “voluntarily”, “informed”, “conscious”, “undetermined”, “uncoerced”, “autonomous”, “controlled”, “uncaused”, etc., is a matter of serious philosophical debate. Much research, either purely philosophical, neuroscientific, or a mixture of the two in nature, has attempted to tease out the mysteries of free will. In spite of being seemingly committed to addressing these questions scientifically, much of the neuroscientific literature clearly holds presuppositions about the nature of free will that stunts its exploratory power. By this, we mean that many neuroscientific experiments surrounding free will have clung to a static metaphysical notion of its existence and it is only recently that a more dynamic view has emerged. The contrast between these two metaphysical beliefs is the focus of our blog post.

Brain might not stand in the way of free will

By Anil Ananthaswamy
New Scientist
Originally published July 13, 2013

Here is an excerpt:

"Libet argued that our brain has already decided to move well before we have a conscious intention to move," says Schurger. "We argue that what looks like a pre-conscious decision process may not in fact reflect a decision at all. It only looks that way because of the nature of spontaneous brain activity."

So what does this say about free will? "If we are correct, then the Libet experiment does not count as evidence against the possibility of conscious will," says Schurger.

Cognitive neuroscientist Anil Seth of the University of Sussex in Brighton, UK, is impressed by the work, but also circumspect about what it says about free will. "It's a more satisfying mechanistic explanation of the readiness potential.

Can we live without free will?

The New Scientist
Opinion
Originally published on August 9, 2012

New research has reignited the debate about whether humans truly have free will. But what difference would it make if we didn't?

DOES it matter if we have free will? Science has been casting doubt on the concept almost from its beginnings. At first, it was the laws of physics that gave pause for thought. The Newtonian "clockwork universe", in which everything unfolds predictably from any given starting position, seemingly affords little scope for human autonomy.

That deterministic vision was overthrown by the introduction of quantum randomness. This hasn't saved free will, though. On the contrary, it has confused the concept of human agency. But few of us see this as reason to abandon our understanding of how free will operates in our everyday lives.

Free Will, Responsibility, and Psychology

Greg Caruso and Bruce Waller Discussion
Philosophy TV
Originally posted December 16, 2013

Most people believe that we can and should be held morally responsible for our actions. Caruso and Waller both hold that this belief is not only false, but harmful. They recommend that we abandon the notion of moral responsibility. But they disagree about free will: Waller thinks that we can preserve a scientifically and philosophically respectable notion of free will without moral responsibility; Caruso thinks that free will and moral responsibility should both be rejected. They begin their discussion with an overview of the traditional problem of free will (1:09). Next, they discuss Waller’s view of free will (9:14) and debate whether the notion of free will ought to be given up (23:51). Then they lay out their reasons to be skeptical about moral responsibility (41:04) and consider some of the concerns that have been expressed by defenders of moral responsibility (54:05).

Causes, Laws, and Free Will: Why Determinism Doesn't Matter

Book Review by Christopher Evan Franklin
Notre Dame Philosophical Reviews

Book: Causes, Laws, and Free Will: Why Determinism Doesn't Matter
Oxford University Press, 2013, 284pp., $65.00 (hbk), ISBN 9780199795185.

Kadri Vihvelin offers a detailed and rigorous inquiry into the classic free will debate, defending four main theses: (1) that free will is possible, (2) that Frankfurt-style cases (FSCs) fail to undermine the traditional debate about the compatibility of free will and determinism, (3) that there are no good arguments for incompatibilism, and (4) that we possess free will in virtue of both possessing a bundle of dispositions and being situated in environments in which there are no obstacles to the manifestation of these dispositions. She dubs the position that emerges from her discussion "commonsense metaphysical compatibilism" (32). Her position on free will is 'commonsense' because it agrees with commonsense that we have free will and are morally responsible (32-3). Her position is 'metaphysical compatibilism' because it contends that free will and moral responsibility are compatible with determinism because the ability to do otherwise is compatible with determinism (18). Her metaphysical compatibilism is to be contrasted with "moral compatibilism", which defends the compatibility of moral responsibility and determinism by denying that the ability to do otherwise is necessary for moral responsibility.

Neuroscience and Free Will: New study debunks Libet’s interpretation

By Justin Caouette
A Philosopher's Take
Originally published August 10, 2012

The interconnection of neuroscience and free will has many researchers trying to make bold claims about their findings. In my last post I called Sam Harris’ conclusion that “free will is an illusion” into question. Specifically, I suggested that there were competing interpretations that could be made from the data that neuroscientist Benjamin Libet was using to debunk free will (I mentioned Al Mele’s interpretation as a counterexample to Libet’s). Finally, some neuroscientists seem to have considered Mele’s suggestion (though interestingly I read no reference to Mele) and did some science to test his alternative interpretation. It turns out that Mele was right,and in turn, that Libet was a bit hasty with his conclusion, as was Sam Harris. Click here for the New Scientist article detailing the study. So it seems that the criticisms I levied against Harris might have more sticking power as a result. Seems that Libet has been debunked and not free will. Below you’ll find some central points directly taken from the New Scientist article.

Why you don't really have free will

By Jerry Coyne
USA Today
Originally published in January 2012, but still relevant today.

Here are two excerpts:

The debate about free will, long the purview of philosophers alone, has been given new life by scientists, especially neuroscientists studying how the brain works. And what they're finding supports the idea that free will is a complete illusion.

The issue of whether we have of free will is not an arcane academic debate about philosophy, but a critical question whose answer affects us in many ways: how we assign moral responsibility, how we punish criminals, how we feel about our religion, and, most important, how we see ourselves — as autonomous or automatons.

(cut)

But two lines of evidence suggest that such free will is an illusion.

The first is simple: we are biological creatures, collections of molecules that must obey the laws of physics. All the success of science rests on the regularity of those laws, which determine the behavior of every molecule in the universe. Those molecules, of course, also make up your brain — the organ that does the "choosing." And the neurons and molecules in your brain are the product of both your genes and your environment, an environment including the other people we deal with. Memories, for example, are nothing more than structural and chemical changes in your brain cells. Everything that you think, say, or do, must come down to molecules and physics.

True "free will," then, would require us to somehow step outside of our brain's structure and modify how it works. Science hasn't shown any way we can do this because "we" are simply constructs of our brain. We can't impose a nebulous "will" on the inputs to our brain that can affect its output of decisions and actions, any more than a programmed computer can somehow reach inside itself and change its program.

The entire, interesting article is here.  Feel free to read it or not, but I know some of you have no choice but to read it, while others not.

Interview with Paul Russell on Free Will and Responsibility

Many philosophical theories try to evade the uncomfortable truth that luck and fate play a role in the conduct of our moral lives, argues the philosopher. He chooses the best books on free will and responsibility.

By Nigel Warburton @philosophybites
Five Books
Originally published December 2, 2013

What is free will?

Our interest in free will starts from our self-image. We are conscious of being agents in the world, capable of doing things and being active. We believe that we can intervene and order our own fate. We’re in control of the trajectory of our own life. That self-image immediately tracks something that is deeply important to us, which is our sense that we are also moral agents. We are accountable to one another for the quality of our actions and what flows from them.

So the problem of free will starts off at a very general level with the question ‘Are we really in control?’ In particular, is our view of ourselves as accountable, moral, ethical agents — which is intimately connected with that self-image — really accurate?

Most people feel, to some degree, in control of how they behave. There may be moments when they become irrational and other forces take over,  or where outside people force them to do things, but if I want to raise my hand or say “Stop!” those things seem to be easily within my conscious control. We also feel very strongly that people, including ourselves, merit praise and blame for the actions they perform because it’s us that’s performing them. It’s not someone else doing those things. And if we do something wrong, knowingly, it’s right to blame us for that.

That’s right. The common sense view — although we may articulate it in different ways in different cultures — is that there is some relevant sense in which we are in control and we are morally accountable. What makes philosophy interesting is that sceptical arguments can be put forward that appear to undermine or discredit our confidence in this common sense position. One famous version of this difficulty has theological roots. If, as everyone once assumed, there is a God, who creates the world and has the power to decide all that happens in it, then our common sense view of ourselves as free agents seems to be threatened, since God controls and guides everything that happens – including all our actions. Similar or related problems seem to arise with modern science.

The scientific challenge is that for everything that we do, we can explain it causally. There’s some prior cause that made us do that — you can go back to childhood, to genetics, early conditioning, environmental factors. When you give the full picture, it seems there is no room for freedom.

Exactly. As in a lot of other familiar philosophical problems, critical reflection and self-consciousness about our commitments erodes our natural easy confidence, or, if you want, our complacency.

US courts see rise in defendants blaming their brains for criminal acts

By Ian Sample, Science Correspondent in San Diego
The Guardian, Sunday 10 November 2013

Criminal courts in the United States are facing a surge in the number of defendants arguing that their brains were to blame for their crimes and relying on questionable scans and other controversial, unproven neuroscience, a legal expert who has advised the president has warned.

Nita Farahany, a professor of law who sits on Barack Obama's bioethics advisory panel, told a Society for Neuroscience meeting in San Diego that those on trial were mounting ever more sophisticated defences that drew on neurological evidence in an effort to show they were not fully responsible for murderous or other criminal actions.

Lawyers typically drew on brain scans and neuropsychological tests to reduce defendants' sentences, but in a substantial number of cases the evidence was used to try to clear defendants of all culpability.

Are We Just a Bunch of Busybodies? (A Dialogue)

Originally posted on November 9, 2013

Here is an excerpt:

Busybody [biz-ee-bod-ee] noun: a person who pries into or meddles in the affairs of others.

In the last two posts I described some cases that are hard for most existing theories of moral responsibility to handle.  What I want to suggest in this post is that any attempt to develop a systematic condition-based theory of responsibility is both philosophically and morally problematic.   Why morally?  Because it turns philosophers into meddlesome busybodies who stick their noses in the private affairs of others and don't know when to mind their own business.

So here's the set-up:  Sarah is at a party and has a few too many glasses of wine on a relatively empty stomach.  She overhears her colleague Emma talking about her in another conversation.  She’s drunk and she misinterprets the meaning of Emma’s remarks and gets angry.  Without thinking, Sarah confronts Emma and lets off some biting insults about her performance at work.  Emma is bewildered and humiliated in front of her friends and co-workers.  Soon, the initial misunderstanding is cleared up and Sarah, mortified, realizes she was way out of line. She offers a bunch of drunken apologies, but the damage is done.  Emma is furious and resentful and Sarah feels terrible overwhelming guilt what happened.

Epigenetics: How to alter your genes

We’ve long been told our genes are our destiny. But it’s now thought they can be changed by habit, lifestyle, even finances. What does this mean for our children?

By Chris Bell
The Telegraph
Originally published on October 16, 2013

Here is an excerpt:

And yet a quiet scientific revolution is changing that thinking. For it seems you might also be what your mother ate. How much your father drank. And what your grandma smoked. Likewise your own children, too, may be shaped by whether you spend your evenings jogging, worrying about work, or sat on the sofa eating Wotsits. And that nurture, rather than our intractable nature, may determine who we are far more than was ever previously thought.

Epigenetics is a relatively new scientific field; research only began in earnest in the mid Nineties, and has only found traction in the wider scientific community in the last decade or so. And the sources of its data are eclectic, to say the least – stretching from famines in northern Sweden to the 9/11 attacks to the medical notes of Audrey Hepburn.

Ethics: Taboo genetics

By Ericka Check Hayden
Nature.com
Originally published October 2, 2013

Here is an excerpt:

At the root of this caution is the widespread but antiquated idea that genetics is destiny — that someone's genes can accurately predict complex behaviours and traits regardless of their environment. The public and many scientists have continued to misinterpret modern findings on the basis of this — fearing that the work will lead to a new age of eugenics, preemptive imprisonment and discrimination against already marginalized groups.

“People can take science and assume it is far more determinative than it is — and, by making that assumption, make choices that we will come to regret as a society,” says Nita Farahany, a philosopher and lawyer at Duke University School of Law in Durham, North Carolina.

But trying to forestall such poor choices by drawing red lines around certain areas subverts science, says Christopher Chabris of Union College in Schenectady, New York. Funding for research in some areas dries up and researchers are dissuaded from entering promising fields. “Any time there's a taboo or norm against studying something for anything other than good scientific reasons, it distorts researchers' priorities and can harm the understanding of related topics,” he says.

The Neural Basis of Free Will: Criterial Causation by Peter Ulric Tse (MIT Press, 2013)

By Stephen L. Macknik | August 12, 2013
Scientific American Book Review

Here are two excerpts:

If our universe is deterministic in this way there can be no free will because you were destined to make that same decision—every single one of your decisions—from the very moment of the big bang. It’s not that you don’t make decisions: you do. But you’ll make them the same exact way in two different universes that have identical big bangs. It means that the universe conspired from its very inception to bring you and your significant other together. It’s quite romantic, actually, so long as you’ve been fortunate enough to have a nice life. But if not, you’re truly screwed, and the universe has been literally plotting your demise for the last 14 billion years.

(cut)

Tse has thought through this enormous problem and realized something important that brings free will back to the realm of the living. Remember that determinism is an unavoidable fact of the universe at the macroscopic but not the quantum level. Well what if the macroscopic universe is not deterministic because the brain is designed to amplify quantum level particle effects to the macroscopic level through the action of specialized neuronal channels that make decisions potentially truly stochastic?

Does non-belief in free will make us better or worse?

Studies have shown that people who believe things happen randomly and not through our own choice often behave much worse than those who believe the opposite.

Are you reading this because you chose to? Or are you doing so as a result of forces beyond your control?

After thousands of years of philosophy, theology, argument and meditation on the riddle of free will, I’m not about to solve it for you in this column (sorry). But what I can do is tell you about some thought-provoking experiments by psychologists, which suggest that, regardless of whether we have free will or not, whether we believe we do can have a profound impact on how we behave.

The issue is simple: we all make choices, but could those choices be made otherwise? From a religious perspective it might seem as if a divine being knows all, including knowing in advance what you will choose (so your choices could not be otherwise). Or we can take a physics-based perspective?

Is Neuroscience the Death of Free Will?

By Eddy Nahmias
The New York Times - Opinionator
Originally published November 13, 2011, but still relevant

Is free will an illusion?  Some leading scientists think so.  For instance, in 2002 the psychologist Daniel Wegner wrote, “It seems we are agents. It seems we cause what we do… It is sobering and ultimately accurate to call all this an illusion.” More recently, the neuroscientist Patrick Haggard declared, “We certainly don’t have free will.  Not in the sense we think.”  And in June, the neuroscientist Sam Harris claimed, “You seem to be an agent acting of your own free will. The problem, however, is that this point of view cannot be reconciled with what we know about the human brain.”

Such proclamations make the news; after all, if free will is dead, then moral and legal responsibility may be close behind.  As the legal analyst Jeffrey Rosen wrote in The New York Times Magazine, “Since all behavior is caused by our brains, wouldn’t this mean all behavior could potentially be excused? … The death of free will, or its exposure as a convenient illusion, some worry, could wreak havoc on our sense of moral and legal responsibility.”
