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.”
