Me and My Brain: What the “Double-Subject Fallacy” reveals about contemporary conceptions of the Self

MiBMy latest essay for 3 Quarks Daily is up: Me and My Brain: What the “Double-Subject Fallacy” reveals about contemporary conceptions of the Self

Here’s an excerpt:
What is a person? Does each of us have some fundamental essence? Is it the body? Is it the mind? Is it something else entirely? Versions of this question seem always to have animated human thought. In the aftermath of the scientific revolution, it seems as if one category of answer — the dualist idea that the essence of a person is an incorporeal soul that inhabits a material body — must be ruled out. But as it turns out, internalizing a non-dualist conception of the self is actually rather challenging for most people, including neuroscientists.
 A recent paper in the Journal of Cognitive Neuroscience suggests that even experts in the sciences of mind and brain find it difficult to shake off dualistic intuitions. Liad Mudrik and Uri Maoz, in their paper “Me & My Brain”: Exposing Neuroscienceʼs Closet Dualism, argue that not only do neuroscientists frequently lapse into dualistic thinking, they also attribute high-level mental states to the brain, treating these states as distinct from the mental states of the person as a whole. They call this the double-subject fallacy. ( I will refer to the fallacy as “dub-sub”, and the process of engaging in it as “dub-subbing”.) Dub-subbing is going on in constructions like”my brain knew before I did” or “my brain is hiding information from me”. In addition to the traditional subject — “me”, the self, the mind — there is a second subject, the brain, which is described in anthropomorphic terms such as ‘knowing’ or ‘hiding’. But ‘knowing’ and ‘hiding’ are precisely the sorts of things that we look to neuroscience to explain; when we fall prey to the double-subject fallacy we are actually doing the opposite of what we set out to do as materialists.  Rather than explaining “me” in terms of physical brain processes, dub-subbing induces us to describe the brain in terms of an obscure second “me”. Instead of dispelling those pesky spirits, we allow them to proliferate!

Is neuroscience really ruining the humanities?

For my latest 3QD post, I expanded on my answer to a Quora question: Is neuroscience ruining the humanities?


Here’s an excerpt:

“Neuroscience is ruining the humanities”. This was the provocative title of a recent article by Arthur Krystal in The Chronicle of Higher Education. To me the question was pure clickbait [1], since I am both a neuroscientist and an avid spectator of the drama and intrigue on the other side of the Great Academic Divide [2]. Given the sensational nature of many of the claims made on behalf of the cognitive and neural sciences, I am inclined to assure people in the humanities that they have little to fear. On close inspection, the bold pronouncements of fields like neuro-psychology, neuro-economics and neuro-aesthetics — the sorts of statements that mutate into TED talks and pop science books — often turn out to be wild extrapolations from a limited (and internally inconsistent) data set.

Unlike many of my fellow scientists, I have occasionally grappled with the weighty ideas that emanate from the humanities, even coming to appreciate elements of postmodern thinking. (Postmodern — aporic? — jargon is of course a different matter entirely.) I think the tapestry that is human culture is enriched by the thoughts that emerge from humanities departments, and so I hope the people in these departments can exercise some constructive skepticism when confronted with the latest trendy factoid from neuroscience or evolutionary psychology. Some of my neuroscience-related essays here at 3QD were written with this express purpose [3, 4].

The Chronicle article begins with a 1942 quote from New York intellectual Lionel Trilling: “What gods were to the ancients at war, ideas are to us”. This sets the tone for the mythic narrative that lurks beneath much of the essay, a narrative that can be crudely caricatured as follows. Once upon a time the University was a paradise of creative ferment. Ideas were warring gods, and the sparks that flew off their clashing swords kept the flames of wisdom and liberty alight. The faithful who erected intellectual temples to bear witness to these clashes were granted the boon of enlightened insight. But faith in the great ideas gradually faded, and so the golden age came to an end. The temple-complex of ideas began to decay from within, corroded by doubt. New prophets arose, who claimed that ideas were mere idols to be smashed, and that the temples were metanarrative prisons from which to escape. In this weak and bewildered state, the intellectual paradise was invaded. The worshipers were herded into a shining new temple built from the rubble of the old ones. And into this temple the invaders’ idols were installed: the many-armed goddess of instrumental rationality, the one-eyed god of essentialism, the cold metallic god of materialism…

The over-the-top quality of my little academia myth might give the impression that I think it is a tissue of lies. But perhaps more nuance is called for. As with all myths, I think there are elements of truth in this narrative.

Science: The Quest for Symmetry


My latest 3QD post is up. This time I’m talking about symmetry and its relationship with science.

Here’s a snippet:

Attitudes toward science in the public sphere occupy an interesting spectrum. At one extreme there are the cheerleaders — those who seem to think that science is the disembodied spirit of progress itself, and will usher us into a brave new world of technological transcendence, in which we will merge with machines and upload our minds to the cloud. At the other extreme there is decidedly less exuberance. Science in its destructive avatar is often called scientism, and is seen as a hegemonic threat to religions and to the humanities, an imperial colonizer of the mind itself.

The successes of science give the impression that it has no limitations, either in outer space or inner space. But this attitude attributes to science somewhat magical powers. The discourse surrounding science might benefit from an awareness that its successes are closely tied to its limitations. The relationship between scientists and the rest of society needs mutual understanding and constructive criticism, rather than a volatile mix of reverence, fear, and mistrust. The veil of the temple of knowledge must be torn in two — or at least lifted up from time-to-time.

To this end, it might be illuminating to see scientific ideas as tools forged in workshops, rather than spells divined by wizards in ivory towers. The tool metaphor also reminds us that science is not merely an outgrowth of western philosophy — it is also the result of the painstaking work of “miners, midwives and low mechanicks” whose names rarely feature in the annals of Great Men. [1]

So what sort of toolbox is science? I’d like to argue that it’s a set of lenses. These lenses allow us to magnify and clarify our perceptions of natural phenomena, setting the stage for deeper understanding. The lenses of science reveal the symmetries of nature, so we might call them the Symmetry Spectacles. The Symmetry Spectacles are normally worn by mathematicians and theoretical physicists, but I think that even laypeople interested in science might find that the world looks quite interesting when viewed through them.

Does dopamine produce a feeling of bliss? On the chemical self, the social self, and reductionism.

Here’s the intro to my latest blog post at 3 Quarks Daily.

“The  osmosis of neuroscience into popular culture is neatly symbolized by a  phenomenon I recently chanced upon: neurochemical-inspired jewellery. It  appears there is a market for silvery pendants shaped like molecules of  dopamine, serotonin, acetylcholine, norepinephrine and other celebrity  neurotransmitters. Under pictures of dopamine necklaces, the  neuro-jewellers have placed words like “love”, “passion”, or “pleasure”.  Under serotonin they write “happiness” and “satisfaction”, and under  norepinephrine, “alertness” and “energy”. These associations presumably  stem from the view that the brain is a chemical soup in which each  ingredient generates a distinct emotion, mood, or feeling. Subjective  experience, according to this view, is the sum total of the  contributions of each “mood molecule”. If we strip away the modern  scientific veneer, the chemical soup idea evokes the four humors of  ancient Greek medicine: black bile to make you melancholic, yellow bile  to make you choleric, phlegm to make you phlegmatic, and blood to make  you sanguine.

“A dopamine pendant worn round the neck as a symbol for bliss is  emblematic of modern society’s attitude towards current scientific  research. A multifaceted and only partially understood set  of experiments is hastily distilled into an easily marketed molecule of  folk wisdom. Having filtered out the messy details, we are left with an  ornamental nugget of thought that appears both novel and reassuringly  commonsensical. But does neuroscience really support this reductionist  view of human subjectivity? Can our psychological states be understood  in terms of a handful of chemicals? Does neuroscience therefore pose a  problem for a more holistic view, in which humans are integrated in  social and environmental networks? In other words, are the “chemical  self” and the “social self” mutually exclusive concepts?”

The Mysterious Power of Naming in Human Cognition

I’ve written a long-form essay for the blog/aggregator site 3 Quarks Daily

Boundaries and Subtleties: the Mysterious Power of Naming in Human Cognition

Here’s a taster:

I’ve divided up the essay into four parts. Here’s the plan:

  1. We’ll introduce two key motifs — the named and the nameless — with a little help from the Tao Te Ching.
  2. We’ll examine a research problem that crops up in cognitive  psychology, neuroscience and artificial intelligence, and link it with  more Taoist motifs.
  3. We’ll look at how naming might give us power over animals, other people, and even mathematical objects.
  4. We’ll explore the power of names in computer science, which will facilitate some wild cosmic speculation.

The neural shadow-play: A metaphor for how we infer how the brain works from a variety of methods

Can we say that a particular brain area mediates some function? My answer to a good Quora question:

Understanding the brain is like understanding the shape of a very complex, dynamic and multifaceted object by looking at the shadows projected by it on a wall.  The color of the light source and its orientation with respect to the object (and the wall) will change the nature of the shadow. Different scientific techniques are like different light sources. Different experimental protocols are like different angles. We have to look at the sequence of shadows and imagine what the object’s actual form is — it is not possible to view this object simultaneously from all angles and with all illumination sources. So there is a degree of creativity and freedom in each person’s own conception of the true nature of the object. Nevertheless, the conception that scientists eventually agree on is likely to be one that tempers this freedom with rationality and responsibility.”

I elaborate on this here:
