Brain Chemistry And The Self - Patricia Churchland Visits NPR's On Point


Oh how do I disagree with thee, let me count the ways . . . .

I have been waging a mostly private war (aside from a few posts on IOC, such as here, for example) against neurophilosopher Patrica Churchland and her reductionist understanding of mind and consciousness.

Essentially, as she argues here and in her new book, Touching A Nerve: The Self As Brain, consciousness, the mind, or the self are each nothing more than the brain. Her argument, as presented, seems obvious because she sets it against the straw man idea of the soul, which no scientist of consciousness takes seriously as an explanation. In a rational sense, she seems to be making a cogent argument.

But hers is a reductionist viewpoint.

A more comprehensive perspective would argue that the mind or the self (and the notion of a self is another straw man, in my opinion - see the work of Thomas Metzinger) is based in the sensorimotor experience of the body-brain, but layered with the subjective experience of being conscious, the intersubjective and interpersonal experience of being in relationship to others, the cultural experience of shared worldviews, and the social, economic, environmental experience of being situated in a particular place and society - all of which is mediated by the temporal experience of time.

It's way past time that the various factions of cognitive neuroscience, embedded/extended mind proponents, and philosophers of subjectivity begin speaking with each other and sharing ideas.

Patricia Churchland: Brain Chemistry And The Self

Brain chemistry and the self. Neurophilosopher Patricia Churchland argues our self is our brain. And that’s it. She joins us

When Galileo took Earth out of the center of the universe, it shook a lot of people’s worlds. Patricia Churchland wants to shake worlds again. She studies the brain and philosophy. A “neurophilosopher”.

And her message is this. That the more we know about the brain, the clearer it becomes that the brain is each of us. That there is no “mind” beyond the brain. No “self” beyond it. No soul, she says. She knows that rocks world now. She’s here to make the case.

This hour, On Point: neurophilosopher Patricia Churchland on the brain as all we are.

From Tom’s Reading List


The New York Times: Science Events — “After early chapters debunking the soul and afterlife, Dr. Churchland gives a nuanced account of sex, violence and morality, working up gently but ambitiously from brain chemicals to ethical norms. She predicts that consciousness, which she believes may be shared in some form by all mammals and birds, will eventually be understood by the convergence of “a million little important results,” not by a miraculous discovery.”

Nature: Neurophilosophy: My brain and I – “Patricia Churchland is the doyenne of neurophilosophers. She believes, as I do, that to understand the mind, one must understand the brain, using evidence from neuroscience to refine concepts such as free will. Many philosophers and others are unhappy with this proposal. The problem, Churchland writes, is that deep down we are all dualists. Our conscious selves inhabit the world of ideas; our brains, the world of objects.”

Psychology Today: Brain Scans and Brain Scams — “If I peek at your brain, can I tell whether you are a criminal? In his book, The Anatomy of Violence, Adrian Raine thinks he can make a pretty good bet. The give away? A bigger bit here or smaller bit there. That is the anatomy his title refers to. My last blog (Criminal brains and criminal genes) unearthed a slew of problems undermining Raine’s idea that we can already identify ‘criminal genes’. Now let’s look closely at his claims to identify criminal brains.”

Interview: Patricia Churchland, The Really Nice Guy Materialist

Julian Baggini interviews neurophilosopher Patricia Churchland in The Philosophers' Magazine, Issue 57, 2nd Quarter 2012. I rather enjoyed her low opinion of Sam Harris's faux neuromorality.

Her most recent book is Braintrust: What Neuroscience Tells Us about Morality (2011) - the paperback comes out September 1.

“Brian McLaughlin wrote the entry on consciousness for the Cambridge Encyclopedia of Consciousness. He said the Churchlands don’t believe in consciousness. And it was so interesting because we had studiously avoided saying any such thing about consciousness. So I phoned Brian after I read this and I said, ‘Well, what the fuck?’”

PATRICIA CHURCHLAND, THE REALLY NICE GUY MATERIALIST

Interview by Julian Baggini

Read most introductions to contemporary philosophy and you might spot something odd. In amongst the carefully drawn pen-portraits of the discipline’s current leading lights are two little cartoon caricatures, there to demonstrate Cicero’s claim that “There is nothing so absurd that some philosopher has not already said it.” In the best cartoon tradition of the Flintstones and the Simpsons, these characters are known simply by their family name: the Churchlands.

Patricia and Paul Churchland’s comedy double-act is not based around funny one-liners, although as I discovered when I caught up with her in Madrid, Patricia is an often very funny conversationalist. The laughs come from the position for which they have become famous: eliminative materialism. Most people who have heard about it believe this entails the denial that we have any thoughts, feelings, emotions or perceptions at all. Churchland recalled one all-too typical example of how this misconception gets around.

“Brian McLaughlin from Rutgers wrote the entry on consciousness for the Cambridge Encyclopedia of Consciousness. He said the Churchlands don’t believe in consciousness. And it was so interesting because we had (a) studiously avoided saying any such thing about consciousness and (b) had some actual ideas worked out with Rudolph Llinás in NYU, who was a physiologist, about what might actually be involved in the brain. So we were, to use the old vocabulary, identity theorists about consciousness. So why would we deny the existence of one of the relata?

“So I phoned Brian after I read this and I said, ‘Well, what the fuck?’ And he said ‘Well, you’re eliminativists,’ and I said, ‘But Brian, have you ever read anything of ours when we say that?” She pauses. “‘Well no.’ And he was very gracious and said ‘I’ll take it out of the next edition,’ which he did.”

Churchland puts some of this down to the sociological fact that “we were these funny little nobodies in this backwards, nothing place in Canada, and I was working in neuroscience, and people thought that this just made for wonderful combination, where really all you had to do was laugh at it, and it would go away.”

We cleared up these misconceptions later, but given how widespread they are, you can understand the trepidation felt by many at the thought of Patricia tackling the issue of morality head-on. But her recent book, Braintrust: What Neuroscience Tells Us about Morality defies such expectations, due largely to the fact that the answer to the question implied by the subtitle is very far from everything. This contrasts starkly with what many see as the scientific hubris of Sam Harris in his recent The Moral Landscape.

“Sam Harris has this vision that once neuroscience is much more developed then neuroscientists will be able to tell us what things are right or wrong, or at least what things are conducive to well-being and not. But even if you cast it in that way, that’s pretty optimistic – or pessimistic, depending on your point of view. Different people even within a culture, even within a family, have different views about what constitutes their own well-being. Some people like to live out in the bush like hermits and dig in the ground and shoot deer for resources, and other people can’t countenance a life that isn’t in the city, in the mix of cultural wonderfulness. So people have fundamentally different ideas about what constitutes well-being.

“I think Sam is just a child when it comes addressing morality. I think he hasn’t got a clue. And I think part of the reason that he kind of ran amuck on all this is that, as you and I well know, trashing religion is like shooting fish in a barrel. If Chris Hitchens can just sort of slap it off in an afternoon then any moderately sensible person can do the same. He wrote that book in a very clear way although there were lots of very disturbing things in it. I think he thought that, heck, it’s not that hard to figure these things out. Morality: how hard can that be? Religion was dead easy. And it’s just many orders of magnitude more difficult.”

What Churchland believes science can do is describe the “neural platform” for ethics. What does she mean by this? It’s perhaps made clearest by looking first at what sits on top of that platform. Moral problems, says Churchland, are essentially “constraint satisfaction problems”.

“For many of the social problems that people have to address, problems of scarcity of resources or what have you, they have to come together, and negotiate, and figure out an amicable solution so that they can carry on. And sometimes those solutions work out fairly well in the short run, and then they have to modify them so they can work out in the longer run. I conceive of that as problem-solving, aka reasoning. And I don’t think neuroscience has anything to say about those things.”

What it does have something to say about is the neural basis which makes such problem solving possible. This “neural platform” is “the basis for sociality, it’s the circuitry in place that makes us want to be with others, that makes us sometimes sacrifice our own interests because we want to be with others, and feel pain when we’re excluded or when we’re ostracized, enjoy the company of others, enjoy the feelings of satisfaction when we co-operate. All those things are the platform. And out of the platform emerges very different social practices, and they’re influenced by many things. History is of course one, but there’s also the ecological conditions. So we can see that certain social practices amongst the Inuit are different from social practices amongst people who are living in Polynesia, and that’s at least partly owing to the fact that life is really, really, really hard in the Arctic.

The Chronicle Review - Is Free Will an Illusion?



The Chronicle Review (from The Chronicle of Higher Education) brought together a group of philosophers and neuroscientists to discuss the nature and even the possibility of free will in the new  reality of brain processes beyond our control.

This post is timely considering the recent publication of Sam Harris's new book, Free Will - an attack (the article calls it a polemic) on the notion that we have control of our individual thoughts and actions - and Michael S. Gazzaniga's Who's In Charge? Free Will and the Science of the Brain - a cogent argument against positions, such as the Harris presents, that our lives are wholly determined by physical processes and we are therefore not responsible for our actions.

What Harris lacks in academic reputation he more than makes up for in cultural popularity, but Gazzaniga is a heavyweight in the world of neuroscience. Harris is likely to win the popular argument, but I'm betting on Gazzaniga to offer the more nuanced and complete perspective. I look forward to reading each of these books.

Is Free Will an Illusion?

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."

The Chronicle Review brought together some key thinkers to discuss what science can and cannot tell us about free will, and where our conclusions might take us.

Gerhard Roth - The Constructive Brain: Neurobiological Aspects of Perception and Cognition


This is an interesting talk on the epistemology of neuroscience, in which the following questions serve as a jumping off point:
  • Is objective ("true") knowledge possible and how can we acquire it?
  • Which role does perception play, which role reasoning, in the acquisition of knowledge?
  • Can perception recognize the world "as it is" ("objectively")?
  • How do my perceptions correspond to the "objective world"?
  • How reliable is perception?
There is some background info on Roth below the video.

Patricia Churchland on Neuroscience and Morality (Brain Science Podcast 81)

Dr. Ginger Campbell, your host of the Brain Science Podcast, has a cool discussion with philosopher Patricia Churchland on the topics of neuroscience and morality. They discuss Churchland's new book, Braintrust: What Neuroscience Tells Us about Morality.

Patricia Churchland on Neuroscience and Morality (BSP 81)

Ginger Campbell, MD

BSP 81 marks the return of philosopher Patricia Churchland, who I first interviewed back in Episode 55. Our recent conversation focuses on her latest book, Braintrust: What Neuroscience Tells Us about Morality. We discuss the historical background and contrast Churchland's approach to that of Sam Harris in The Moral Landscape. Then Professor Churchland discusses how recent discoveries in neuroscience are shedding light on the evolutionary origins of morality. It's a fascinating conversation that you won't want to miss.
