Non-Duality’s No-Self and Antonio Damasio

Antonio Damasio No-Self Non-Duality Zen Descartes' Error
Non-Duality’s No-Self and Antonio Damasio

Non-Duality is the term for a view of the world as not two, but one—not the duality of a person and the world outside him or her, but instead a subjective experience in which the perceiver and the perceived participate with one another in a sense, according to some experiencers, that all is part of incessant movement, a dance, so to speak. There is no experiencer, no experienced. All is experienc-ing. Everything is part of the subjectivity, with nothing outside. The view derives from Eastern belief, principally Hindu advaita, which literally means without duality and from Buddhism (Zen, for example).

A central tenet of non-duality is that self—that which we call our self—does not exist. The evidence is offered by a methodology. The disciple is told to look for his self, and to do so relentlessly. Eventually, he concludes that he cannot find it. Only thoughts, feelings, and sensations are there. These are subjective—part of a world which is wholly conscious and without "external" objects. As for the chair in which he sits, all that is also subjective. The pressure of his body against the seat is sensation. His visual perception of it is also sensation. A sense of self-survival does not disappear. What fades eventually or vanishes abruptly is the autobiographical self, the sensation that "I am angry," or "I am upset," as examples. Sub-personalities remain. The predilection for mystery novels, as an example, does not go away. A liking of certain types of people remains. One still gets angry, etc, but the sensation passes quickly rather than lingering as fixed-cause for the autobiographical self ("They are always doing that to me.") Advaita and Buddhism have no problem with Damasio's arguments.

The reader would be unwise to dismiss all this as so much balderdash. Quite able intellects, including philosphers George Berkeley and David Hume, have been unable to disregard conclusions they reached. Hume, for example, concluded as much about the self—that insufficient evidence can be found for its existence. Berkeley posited that nothing is material, and to be is to be perceivedEsse est percipi. Speaking only about self, Antonio Damasio has a different take on the situation. Damasio, M.D., Ph.D., currently is Allen Professor of Neurology, and Head of the Neurology Department at the University of Iowa. In Descartes’ Error* he offers another way to look at the phenomenon of the self. (* Subtitled, Emotion, Reason, and The Human Brain) As an example of his point, he refers to neural signals from the elbow joint. Of these signals he says, they



  • will happen in the early somatosensory cortices in the insular regions [of the brain].”

    Of them, he also states,



  • “Note again, that this is a collection of areas, rather than one center.”

    With this comment Damasio offers a point of view as to why the self cannot be found when we introspect for it, either through deliberate search or with meditation. We gain a simple inference from his remark. Introspection requires focus, and focus implies search for isolated neural phenomena. The self is not part of isolated phenomena. It is part of a collective. Picture the focused beam of a flashlight. Self cannot be found with such a search.

    By again referring to the early sensory cortices in the brain, he elaborates and makes an important observation regarding the self. First, the build-up to his comments on the self, then what he has to say about the self. In the build-up to his points, he explains that the early sensory cortices generate topographical representations. That is, the cortices represent sensory input to other areas of the brain. But if that were the end of it,

  • ”I doubt we would ever be conscious of them as images. How would we know they are our images? “

    He states that they would mean nothing to us, these representations. We would not know what to do with them. He says something would be missing, subjectivity—a subject to make meaning out of them. Something else is needed. Here is his first point:



  • “In essence, those neural representations must be correlated with those which, moment by moment, constitute the neural basis for the self. “

    That is, without a sense of self, they offer no utility for the organism, which must use them to survive in the moment or to plan ahead. It must make meaning out of them.

    He lays to rest the homunculus, the little man inside, the intermediary, which somehow bridged Descartes’ gap between mind and the world outside. His second point:

  • “Self is not the infamous homunculus, a little person inside our brain, perceiving and thinking about the images the brain forms. It is, rather, a perpetually re-created neurobiological state. Years of justified attack on the homunculus concept have made many theorists equally fearful of the concept of self. [Emphasis mine—he does not lend support to the no-self camp] But the neural self need not be homuncular at all. What should cause some fear, actually, is the idea of a selfless cognition.”

    In short, cognition cannot occur without a self to cognize things. Introspect, meditate, all you want but, according to Damasio, don’t use your findings as evidence of no-self. Given his explanation, the attempt to find a self implies cognition at work, with a self involved in the effort. Even though self cannot be found—because cognition involves focus and self is non-focused—the neural self is involved in the very attempt to find itself.

  • Damasio's thesis in Descartes' Error is that Rene Descartes mistakenly held that thinking can be separated from emotion. That can be found in Mind Shadows at Descartes' Error:Antonio Damasio, Somatic Markers, As-If Loops, and Moral Decision-Making, 11 April 2004.

    Manufacturing Consent IV: The Bewildered Herd

    Neil Postman Amusing Ourselves to Death Manufacture Consent Mass Media
    Manufacturing Consent, IV: The Bewildered Herd

    This article provides background to the earlier articles on manufacturing consent in the United States, a phenomenon with a scale unprecedented among wealthy nations. Somehow, consent toward corporate values has become assimilated into Mother Culture of America. Few people even think to question how they get the memes that form their opinions, view points, and beliefs about matters social and political. This, Part Four, touches upon early views of social engineering, as well as upon recognition that it has become a major instrument of government. (For articles on memes, see Memes, Genes, and God, 31 December 2003; Memes and Why Evolution Favored The Irrational Brain, 26 February 2004; Beyond Memes, 6 March 2004.)

    Two hundred years ago, the idea of democracy was ripening, and would blossom into the French and American Revolutions, although not everybody thought it a good thing. The masses were regarded with suspicion, and aristocracy with favor. Some, though, simply looked at the situation objectively. Eighteenth Century philosopher David Hume found "nothing more surprising" than

    " to see the easiness with which the many are governed by the few; and to observe the implicit submission with which men resign their sentiments and passions to those of their rulers. When we enquire by what means this wonder is brought about, we shall find, that as Force is always on the side of the governed, the governers have nothing to support them but opinion. 'Tis therefore, on opinion only that government is founded; and this maxim extends to the most despotic and most military governments, as well as to the most free and most popular." (Essays Moral, Political, and Literary)

    Walter Lippmann, early Twentieth Century political and social pundit, wrote that "the public must be put in its place" so that we may "live free of the trampling and the roar of a bewildered herd," which serves to be "interested spectators of action," and not participants. As a "responsible" pubic intellectual, he saw his duty as guiding the voice of the herd in case government does not have sufficient sway over the public. (The Phantom Public)

    Gore Vidal, a prominent, current, novelist and intellectual, has a different take on the situation: "To deny inconvenient opinions a hearing is one way the few have of controlling the many. But as Richard Nixon used to say, ' That would be the easy way.' The slyer way is to bombard the public with misinformation. During more than half a century of corruption by the printed word in the form ' news' --propaganda disguised as fact--I have yet to read a story favorable to another society's social and political arrangements. Swedes have free health care, better schools than ours, child day-care center for working mothers. . . but the Swedes are all drunks who commit suicide (even blonde blue-eyed people must pay for such decadent amenities). Lesson [for the bewildered herd]? No national health care, no education [with high national budget priority] , etc. . . . ."

    "Of the billions now spent each election cycle, most is donated in checks of $1,000 or more. But less than one-tenth of one percent of the general population make individual contributions at this rate. These happy few are prepared to pay a high and rising price for the privilege of controlling our government. In the 1998 election cycle, the average winning House candidate cost the owners about $600,000. The average winning Senate candidate a bit over $5 million. Multiply both figures by two if you want the cost of dislodging an incumbent from office (in a system where, last time around, over 97 percent were re-elected). To finance a race in big media markets like New York, or California, it's a bit more expensive: as of election day 1998, something like $36 and $21 million respectively."

    "The corporate grip on opinion in the United States is one of the wonders of the Western world. No First World country has ever managed to eliminate so entirely from its media all objectivity--much less dissent."

    "Of course, it is possible for any citizen with time to spare, and a canny eye, to work out what is actually going on, but for the many there is not time, and the network news is the only news even though it may not be news at all but only a series of flashing fictions. . . ." (The Decline and Fall of The American Empire)

    Nothing manufactures consent like fear. It guarantees that the bewildered herd will be tamed to conform to the expectations of the governing elite. A common threat marginalizes dissidents, activates supporters, and sways the undecided. It silences all opposing voices. If terrorists strike again in America, the November elections will be decided on only one issue, the war against terrorism. The economy, joblessness, health insurance, worker pensions, social security, environment, the budget deficit--these and other issues will be rendered null and void for practical purposes.

    "Bewildered herd" refers, of course, to you and me, who have a voice only once very four years. Do you feel bewildered? I don't.
