Sam Harris on non-self in the NY Times
Sam Harris is a neuroscientist and prominent “new atheist,”
who along with others like Richard Dawkins, Daniel Dennett and
Christopher Hitchens helped put criticism of religion at the forefront
of public debate in recent years. In two previous books, “The End of
Faith” and “Letter to a Christian Nation,” Harris argued that theistic
religion has no place in a world of science. In his latest book, “Waking
Up,” his thought takes a new direction. While still rejecting theism,
Harris nonetheless makes a case for the value of “spirituality,” which
he bases on his experiences in meditation. I interviewed him recently
about the book and some of the arguments he makes in it.
Gary Gutting:
A common basis for atheism is naturalism — the view that only science
can give a reliable account of what’s in the world. But in “Waking Up”
you say that consciousness resists scientific description, which seems
to imply that it’s a reality beyond the grasp of science. Have you moved
away from an atheistic view?
Sam Harris:
I don’t actually argue that consciousness is “a reality” beyond the
grasp of science. I just think that it is conceptually irreducible —
that is, I don’t think we can fully understand it in terms of
unconscious information processing. Consciousness is “subjective”— not
in the pejorative sense of being unscientific, biased or merely personal, but in the sense that it is intrinsically first-person, experiential and qualitative.
The only thing in this
universe that suggests the reality of consciousness is consciousness
itself. Many philosophers have made this argument in one way or another —
Thomas Nagel, John Searle, David Chalmers. And while I don’t agree with
everything they say about consciousness, I agree with them on this
point.
The primary approach to understanding consciousness in neuroscience entails correlating changes in its contents with changes in the brain. But no matter how reliable these correlations become, they won’t allow us to drop the first-person side of the equation. The experiential character of consciousness is part of the very reality we are studying. Consequently, I think science needs to be extended to include a disciplined approach to introspection.

G.G.:
But science aims at objective truth, which has to be verifiable: open
to confirmation by other people. In what sense do you think first-person
descriptions of subjective experience can be scientific?
S.H.:
In a very strong sense. The only difference between claims about
first-person experience and claims about the physical world is that the
latter are easier for others to verify. That is an important distinction
in practical terms — it’s easier to study rocks than to study moods —
but it isn’t a difference that marks a boundary between science and
non-science. Nothing, in principle, prevents a solitary genius on a
desert island from doing groundbreaking science. Confirmation by others
is not what puts the “truth” in a truth claim. And nothing prevents us
from making objective claims about subjective experience.
Are you thinking about
Margaret Thatcher right now? Well, now you are. Were you thinking about
her exactly six minutes ago? Probably not. There are answers to
questions of this kind, whether or not anyone is in a position to verify
them.
And certain truths
about the nature of our minds are well worth knowing. For instance, the
anger you felt yesterday, or a year ago, isn’t here anymore, and if it
arises in the next moment, based on your thinking about the past, it
will quickly pass away when you are no longer thinking about it. This is
a profoundly important truth about the mind — and it can be absolutely
liberating to understand it deeply. If you do understand it deeply —
that is, if you are able to pay clear attention to the arising and
passing away of anger, rather than merely think about why you have every
right to be angry — it becomes impossible to stay angry for more than a
few moments at a time. Again, this is an objective claim about the
character of subjective experience. And I invite our readers to test it
in the laboratory of their own minds.
G. G.:
Of course, we all have some access to what other people are thinking or
feeling. But that access is through probable inference and so lacks the
special authority of first-person descriptions. Suppose I told you that
in fact I didn’t think of Margaret Thatcher when I read your comment,
because I misread your text as referring to Becky Thatcher in “The
Adventures of Tom Sawyer”? If that’s true, I have evidence for it that
you can’t have. There are some features of consciousness that we will
agree on. But when our first-person accounts differ, then there’s no way
to resolve the disagreement by looking at one another’s evidence.
That’s very different from the way things are in science.
S.H.:
This difference doesn’t run very deep. People can be mistaken about the
world and about the experiences of others — and they can even be
mistaken about the character of their own experience. But these forms of
confusion aren’t fundamentally different. Whatever we study, we are
obliged to take subjective reports seriously, all the while knowing that
they are sometimes false or incomplete.
For instance, consider
an emotion like fear. We now have many physiological markers for fear
that we consider quite reliable, from increased activity in the amygdala
and spikes in blood cortisol to peripheral physiological changes like
sweating palms. However, just imagine what would happen if people
started showing up in the lab complaining of feeling intense fear
without showing any of these signs — and they claimed to feel suddenly
quite calm when their amygdalae lit up on fMRI, their cortisol spiked,
and their skin conductance increased. We would no longer consider these
objective measures of fear to be valid. So everything still depends on
people telling us how they feel and our (usually) believing them.
However, it is true
that people can be very poor judges of their inner experience. That is
why I think disciplined training in a technique like “mindfulness,”
apart from its personal benefits, can be scientifically important.
G.G.:
You deny the existence of the self, understood as “an inner subject
thinking our thoughts and experiencing our experiences.” You say,
further, that the experience of meditation (as practiced, for example,
in Buddhism) shows that there is no self. But you also admit that we
all “feel like an internal self at almost every waking moment.” Why
should a relatively rare — and deliberately cultivated — experience of
no-self trump this almost constant feeling of a self?
S.H.: Because what does not survive scrutiny cannot be real. Perhaps you can see the same effect in this perceptual illusion:
It certainly looks
like there is a white square in the center of this figure, but when we
study the image, it becomes clear that there are only four partial
circles. The square has been imposed by our visual system, whose edge
detectors have been fooled. Can we know that the black shapes
are more real than the white one? Yes, because the square doesn’t
survive our efforts to locate it — its edges literally disappear. A
little investigation and we see that its form has been merely implied.
What could we say to a
skeptic who insisted that the white square is just as real as the
three-quarter circles and that its disappearance is nothing more than,
as you say, “a relatively rare — and deliberately cultivated —
experience”? All we could do is urge him to look more closely.
The same is true about
the conventional sense of self — the feeling of being a subject inside
your head, a locus of consciousness behind your eyes, a thinker in
addition to the flow of thoughts. This form of subjectivity does not
survive scrutiny. If you really look for what you are calling “I,” this
feeling will disappear. In fact, it is easier to experience
consciousness without the feeling of self than it is to banish the white
square in the above image.
G.G.:
But it seems to depend on who’s looking. Buddhist schools of philosophy
say there is no self, and Buddhist meditators claim that their
experiences confirm this. But Hindu schools of philosophy say there is a
self, a subject of experience, disagreeing only about its exact nature;
and Hindu meditators claim that their experiences confirm this. Why
prefer the Buddhist experiences to the Hindu experiences? Similarly, in
Western philosophy we have the phenomenological method, an elaborate
technique for rigorously describing consciousness. Some phenomenologists
find a self and others don’t. With so much disagreement, it’s hard to
see how your claim that there’s really no self can be scientifically
established.
S.H.:
Well, I would challenge your interpretation of the Indian literature.
The difference between the claims of Hindu yogis and those of Buddhist
meditators largely boil down to differences in terminology. Buddhists
tend to emphasize what the mind isn’t — using words like selfless, unborn, unconditioned, empty, and so forth. Hindus tend to describe the experience of self-transcendence in positive terms — using terms such as bliss, wisdom, being, and even “capital-S” Self. However, in a tradition like Advaita Vedanta, they are definitely talking about cutting through the illusion of the self.
The basic claim,
common to both traditions, is that we spend our lives lost in thought.
The feeling that we call “I”— the sense of being a subject inside the
body — is what it feels like to be thinking without knowing that you are
thinking. The moment that you truly break the spell of thought, you can
notice what consciousness is like between thoughts — that is, prior to
the arising of the next one. And consciousness does not feel like a
self. It does not feel like “I.” In fact, the feeling of being a self is
just another appearance in consciousness (how else could you feel it?).
There are glimmers of
this insight in the Western philosophical tradition, as you point out.
But the West has never had a truly rigorous approach to introspection.
The only analog to a Tibetan or Indian yogi sitting for years in a cave
contemplating the nature of consciousness has been a Christian monastic
exerting a similar effort praying to Jesus. There is a wide literature
on Christian mysticism, of course. But it is irretrievably dualistic and
faith-based. Along with Jews and Muslims, Christians are committed to
the belief that the self (soul) really exists as a separate entity and
that the path forward is to worship a really existing God. Granted,
Buddhism and Hinduism have very crowded pantheons, and a fair number of
spooky and unsupportable doctrines, but the core insight into the
illusoriness of the self can be found there in a way that it can’t in
the Abrahamic tradition. And cutting through this illusion does not
require faith in anything.
G.G.:
Suppose we agree that “spiritual experiences” can yield truths about
reality and specifically accept the truth of Buddhist experiences of
no-self. Many Christians claim to have direct experiences of the
presence of God — not visions or apparitions but a strong sense of
contact with a good and powerful being. Why accept the Buddhist
experiences and reject the Christian experiences?
S.H.:
There is a big difference between making claims about the mind and
making claims about the cosmos. Every religion (including Buddhism) uses
first-person experience to do both of these things, but the latter
pretensions to knowledge are almost always unwarranted. There is nothing
that you can experience in the darkness of your closed eyes that will
help you understand the Big Bang or the connection between consciousness
and the physical world. Look within, and you will find no evidence that
you even have a brain, much less gain any insight into how it works.
However, one can
discover specific truths about the nature of consciousness through a
practice like meditation. Religious people are always entitled to claim
that certain experiences are possible — feelings of bliss or
selfless love, for instance. But Christians, Hindus and atheists have
experienced the same states of consciousness. So what do these
experiences prove? They certainly don’t support claims about the unique
divinity of Christ or about the existence of the monkey god Hanuman. Nor
do they demonstrate the divine origin of certain books. These reports
only suggest that certain rare and wonderful experiences are possible.
But this is all we need to take “spirituality” (the unavoidable term for
this project of self-transcendence) seriously. To understand what is
actually going on — in the mind and in the world — we need to talk about
these experiences in the context of science.
G.G.:
I’m not talking about highly specific experiences of Christ or of a
monkey god. I mean simply a sense of a good and powerful spiritual
reality—no more, no less. Why accept Buddhist experiences but not
experiences like that?
S.H.:
I wouldn’t place the boundary between religious traditions quite where
you do — because Buddhists also make claims about invisible entities,
spiritual energies, other planes of existence and so forth. However,
claims of this kind are generally suspect because they are based on
experiences that are open to rival interpretations. We know, for
instance, that people can be led to feel an unseen presence simply by
having specific regions of their brains stimulated in the lab. And those
who suffer from epilepsy, especially in the temporal lobe, have all
kinds of visionary experiences.
Again, the crucial
distinction is between making claims about reality at large or about
possible states of consciousness. The former is the province of
religious belief and science (though science has standards of
intellectual honesty, logical coherence and empirical rigor that
constrain it, while religion has almost none). In “Waking Up,” I argue
that spirituality need not rest on any faith-based assumptions about
what exists outside of our own experience. And it arises from the same
spirit of honest inquiry that motivates science itself.
Consciousness exists
(whatever its relationship to the physical world happens to be), and it
is the experiential basis of both the examined and the unexamined life.
If you turn consciousness upon itself in this moment, you will discover
that your mind tends to wander into thought. If you look closely at
thoughts themselves, you will notice that they continually arise and
pass away. If you look for the thinker of these thoughts, you will not
find one. And the sense that you have — “What the hell is Harris talking
about? I’m the thinker!”— is just another thought, arising in consciousness.
If you repeatedly turn
consciousness upon itself in this way, you will discover that the
feeling of being a self disappears. There is nothing Buddhist about such
inquiry, and nothing need be believed on insufficient evidence to
pursue it. One need only accept the following premise: If you want to
know what your mind is really like, it makes sense to pay close
attention to it.
