The Way Consciousness Is

Thinking about the United States plumbing the depths of kakistocracy (rule by the worst) is all well and good, but back to consciousness.

The human brain is the most complex object anyone has ever tried to understand. It might be the most complex object in the universe. We might never understand how it works. Robert Burton, a neurologist, writes about being surprised by a patient with a paranoid fear of the FBI that was apparently caused by a mutation in his brain:

Though I didn’t know it at the time, I had run headlong into the “hard problem of consciousness,” the enigma of how physical brain mechanisms create purely subjective mental states. In the subsequent 50 years, what was once fodder for neurologists’ late night speculations has mushroomed into the preeminent question in the philosophy of mind. As an intellectual challenge, there is no equal to wondering how subatomic particles, mindless cells, synapses, and neurotransmitters create the experience of red, the beauty of a sunset, the euphoria of lust, the transcendence of music, or in this case, intractable paranoia.

Neuroscientists have long known which general areas of the brain and their connections are necessary for the state of consciousness. By observing both the effects of localized and generalized brain insults such as anoxia [total lack of oxygen] and anesthesia, none of us seriously doubt that consciousness arises from discrete brain mechanisms. Because these mechanisms are consistent with general biological principles, it’s likely that, with further technical advances, we will uncover how the brain generates consciousness.

However, such knowledge doesn’t translate into an explanation for the what of consciousness—that state of awareness of one’s surroundings and self, the experience of one’s feelings and thoughts. Imagine a hypothetical where you could mix nine parts oxytocin, 17 parts serotonin, and 11 parts dopamine into a solution that would make 100 percent of people feel a sense of infatuation 100 percent of the time. Knowing the precise chemical trigger for the sensation of infatuation (the how) tells you little about the nature of the resulting feeling (the what).

But why should we expect that knowing what chemicals cause the feeling of infatuation would tell us anything about what infatuation feels like? Aren’t those two different questions?

Suppose, however, that we keep improving our techniques for studying the brain, as Burton suggests, and eventually figure out how certain kinds of brain activity become consciousness. It doesn’t seem impossible that one day (maybe 1,000 years in the future) that we will fully understand how “subatomic particles, mindless cells, synapses, and neurotransmitters” allow us to be conscious, just as well as we understand how lungs allow us to breathe (although lungs are a lot less complicated than brains). Suppose we discover how one kind of brain activity becomes a feeling of infatuation and another kind becomes a feeling of resentment. 

Burton implies that we would still be left with what he calls the “what” question, although it might be better to call it the “why” question. Why does our consciousness have the specific properties it does? Why does a note on a violin sound just the way it does? Why does red look like this and not like this or this? In the case of color, scientists might understand perfectly well the relationship between different wavelengths of light, the physiology of our eyes and nervous system, and the colors we see. They would understand that such and such conditions, structures and processes are correlated with seeing red and others are correlated with seeing blue. All of our “how does this happen?” questions would have been answered. So would it still make sense to ask why a particular kind of light looks the way it does or a particular feeling feels the way it does?

I’m not sure it would. Once we understood what leads to colors looking the way they do, or what makes feelings feel the way they do, any “why” questions might disappear. Once we understand the “how” of consciousness, maybe there won’t be anything more to figure out. If there are any neurologists or philosophers still asking “why”, the best answer will be “that’s just the way it is” or “stop asking questions and go to sleep”.

That wouldn’t necessarily be a bad thing. After all, in science, we sometimes arrive at what appear to be “brute” facts. Why is the speed of light in a vacuum 186,282 miles per second instead of 186,300 miles per second? We may never know. That’s just the way the universe works. No further explanation is available. If you have a problem with our speed of light, go live in another universe. If you don’t like the particular colors you see, keep your eyes closed. Or become a cat.

Next up on this subject, assuming I stay conscious: What does it mean to say consciousness is a physical phenomenon? It’s obviously a mental phenomenon, so how can it be a physical one too?

Yes, It’s Your Doom and Gloom Roundup, But Maybe With Light at the End of the Tunnel

Arthur Schopenhauer, “On the Sufferings of the World” (1836):

In early youth, as we contemplate our coming life, we are like children in a theater before the curtain is raised, sitting there in high spirits and eagerly waiting for the play to begin. It is a blessing that we do not know what is really going to happen. 

You tell ’em, Art.

Craig Unger, “Trump’s Russian Laundromat”, The New Republic:

A review of the public record reveals a clear and disturbing pattern: Trump owes much of his business success, and by extension his presidency, to a flow of highly suspicious money from Russia. Over the past three decades, at least 13 people with known or alleged links to Russian mobsters or oligarchs have owned, lived in, and even run criminal activities out of Trump Tower and other Trump properties. Many used his apartments and casinos to launder untold millions in dirty money…. Others provided Trump with lucrative branding deals that required no investment on his part. Taken together, the flow of money from Russia provided Trump with a crucial infusion of financing that helped rescue his empire from ruin, burnish his image, and launch his career in television and politics….

By 2004, to the outside world, it appeared that Trump was back on top after his failures in Atlantic City. That January, flush with the appearance of success, Trump launched his newly burnished brand into another medium.

[The Apprentice] instantly revived his career. “The Apprentice turned Trump from a blowhard Richie Rich who had just gone through his most difficult decade into an unlikely symbol of straight talk, an evangelist for the American gospel of success, a decider who insisted on standards in a country that had somehow slipped into handing out trophies for just showing up,” … Michael Kranish and Marc Fisher observe in their book Trump Revealed. “Above all, Apprentice sold an image of the host-boss as supremely competent and confident, dispensing his authority and getting immediate results. The analogy to politics was palpable”….

Without the Russian mafia, it is fair to say, Donald Trump would not be president of the United States.

I sometimes wonder how many of the millions of people who watched The Apprentice for years and years voted for this “poor person’s idea of a rich person” and whether DT’s shady business deals will ever catch up with him.

Rolf Mowatt-Larssen, “Trump Jr.’s Russia meeting sure sounds like a Russian intelligence operation”, The Washington Post:

….everything we know about the meeting — from whom it involved to how it was set up to how it unfolded — is in line with what intelligence analysts would expect an overture in a Russian influence operation to look like. It bears all the hallmarks of a professionally planned, carefully orchestrated intelligence soft pitch designed to gauge receptivity, while leaving room for plausible deniability in case the approach is rejected. And the Trump campaign’s willingness to take the meeting — and, more important, its failure to report the episode to U.S. authorities — may have been exactly the green light Russia was looking for to launch a more aggressive phase of intervention in the U.S. election….

Had this Russian overture been rejected or promptly reported by the Trump campaign to U.S. authorities, Russian intelligence would have been forced to recalculate the risk vs. gain of continuing its aggressive operation to influence U.S. domestic politics. Russian meddling might have been compromised in its early stages and stopped in its tracks by U.S. intelligence and law enforcement agencies before it reached fruition by the late fall.

So the suggestion that this was a nothing meeting without consequence is, in all likelihood, badly mistaken.

Paul Krugman, “Takers and Fakers”, The New York Times: 

… throughout the whole campaign against Obamacare, Republicans have been lying about their intentions.

Believe it or not, conservatives actually do have a more or less coherent vision of health care. It’s basically pure Ayn Rand: if you’re sick or poor, you’re on your own…. Specifically:

1. Health care, even the most essential care, is a privilege, not a right. If you can’t get insurance because you have a preexisting condition, because your income isn’t high enough, or both, too bad.

2. People who manage to get insurance through government aid, whether Medicaid, subsidies, or regulation and mandates that force healthy people to buy into a common risk pool, are “takers” exploiting the wealth creators, aka the rich.

3. Even for those who have insurance, it covers too much. Deductibles and co-pays should be much higher, to give people “skin in the game”…

4. All of this applies to seniors as well as younger people. Medicare as we know it should be abolished, replaced with a voucher system that can be used to help pay for private policies – and funding will be steadily cut below currently projected levels, pushing people into high-deductible, high-copay private policies.

This is … what conservative health care “experts” say when they aren’t running for public office, or closely connected to anyone who is. I think it’s a terrible doctrine … because buying health care isn’t and can’t be like buying furniture….

But think of how Republicans have actually run against Obamacare. They’ve lambasted the law for not covering everyone, even though their fundamental philosophy is NOT to cover everyone, or accept any responsibility for the uninsured. They’ve denied that their massive cuts to Medicaid are actually cuts, pretending to care about the people they not-so-privately consider moochers. They’ve denounced Obamacare policies for having excessively high deductibles, when higher deductibles are at the core of their ideas about cost control. And they’ve accused Obamacare of raiding Medicare, a program they’ve been trying to kill since 1995.

In other words, their whole political strategy has been based on lies – not shading the truth, not spinning, but pretending to want exactly the opposite of what they actually want.

And this strategy was wildly successful, right up to the moment when Republicans finally got a chance to put their money – or actually your money – where their mouths were. The trouble they’re having therefore has nothing to do with tactics, or for that matter with Trump. It’s what happens when many years of complete fraudulence come up against reality.

As Krugman writes elsewhere:

… everyone, and I mean everyone, who knows something about insurance markets is declaring the same thing: that the [Republican] bill would be a disaster. We’ve got the insurance industry declaring it “simply unworkable”; the American Academy of Actuaries saying effectively the same thing; AARP up in arms; and more [doctors, nurses, state governors, voters]. 

And yet, it still might become law this month. Why?

Jennifer Rubin, “The GOP’s Moral Rot Is the Problem, Not Donald Trump”, The Washington Post:

… for decades now, demonization — of gays, immigrants, Democrats, the media, feminists, etc. — has been the animating spirit behind much of the right. It has distorted its assessment of reality, … elevating Fox News hosts’ blatantly false propaganda as the counterweight to liberal media bias and preventing serious policy debate. For seven years, the party vilified Obamacare without an accurate assessment of its faults and feasible alternative plans. “Obama bad” or “Clinton bad” became the only credo — leaving the party … with “no attachment to any external moral truth or ethical code” — and no coherent policies for governing.

We have always had in our political culture narcissists, ideologues and flimflammers, but it took the 21st-century GOP to put one in the White House….

Out of its collective sense of victimhood came the GOP’s disdain for not just intellectuals but also intellectualism, science, Economics 101, history and constitutional fidelity….the GOP became slaves to its own demons and false narratives. A party that has to deny climate change and insist illegal immigrants are creating a crime wave — because that is what “conservatives” must believe, since liberals do not — is a party that will deny Trump’s complicity in gross misconduct. It’s a party as unfit to govern as Trump is unfit to occupy the White House. It’s not by accident that Trump chose to inhabit the party that has defined itself in opposition to reality and to any “external moral truth or ethical code”. 

Helen Keller, Optimism: An Essay (1903):

The test of all beliefs is their practical effects in life. If it be true that optimism compels the world forward, and pessimism retards it, then it is dangerous to propagate a pessimistic philosophy. One who believes that the pain in the world outweighs the joy, and expresses that unhappy conviction, only adds to the pain. Schopenhauer is an enemy to the race. Even if he earnestly believed that this is the most wretched of possible worlds, he should not promulgate a doctrine which robs men of the incentive to fight with circumstance.

All right, Helen, the good news is that a Republican senator is recovering from surgery and won’t be in Washington this coming week. His vote would be needed to move the Republican bill forward, so the vote has been delayed, giving the opposition more time to terminate this horror show with extreme prejudice.

Hegel: A Very Short Introduction by Peter Singer

Peter Singer is a famous philosopher (as famous as philosophers can be these days) known for his very strong utilitarian views:

He is known especially for his work on the ethics of our treatment of animals, for his controversial critique of the sanctity of life doctrine in bioethics, and for his writings on the obligations of the affluent to aid those living in extreme poverty.  

But he has also written on German philosophy. In 1983, he published Hegel, a brief introduction to the highly influential 19th century philosopher. Hegel is now part of Oxford University Press’s colorful series of “Very Short Introductions”.

Hegel (the philosopher, not the book) wrote a lot and is notoriously hard to understand. That’s one reason so many academics have written about him. Singer does an excellent job. He devotes chapters to four of Hegel’s works (Lectures on the Philosophy of History; Philosophy of Right; The Phenomenology of Mind; and Science of Logic), the principal topics of which are history, freedom, mind and rationality. But since Hegel is what is known as a “systematic” thinker, none of the topics stand alone.

I came away from Hegel with what feels like a better understanding of his thought, although not good enough to explain it to anyone. All I’ll say is that Hegel seems to have viewed Geist (translated as either “mind” or “spirit”) as a real but abstract entity that has progressed through history, advancing toward more and more freedom, culminating in total rationality (the “Absolute”). Singer concludes that Hegel may have been a panentheist:

The term comes from Greek words meaning “all in God”; it describes the view that everything in the universe is part of God, but – and here it differs from pantheism – God is more than the universe, because he is the whole, and the whole is greater than the sum of all its parts. Just as a person is more than all the cells that make up his or her body – although the person is nothing separate from the body – so on this view God is more than all the parts of the universe, but not separate from it. Equally, just as no single cells amount to a person, so no individual parts of the universe amount to God. 

[This] interpretation is plausible, not only because it is consistent with what Hegel says specifically about God, but also because it makes sense of the dominant theme of his philosophy. If God is the absolute idea, the ultimate reality of the universe, the whole of its parts, we can understand why the absolute idea must manifest itself in the world, and there progress to self-comprehension. God needs the universe in the same way a person needs a body.

… Hegel sees God not as eternal and immutable, but as an essence that needs to manifest itself in the world, and, having made itself manifest, to perfect the world in order to be perfect itself…. It is a vision that places immense weight on the necessity of progress: for the onward movement of history is the path God must take to achieve perfection. Therein may lie the secret of the immense influence that Hegel, for all his outward conservatism, has had on radical and revolutionary thinkers [note: Karl Marx being the most obvious instance].

Fear of Knowledge: Against Relativism and Constructivism by Paul Boghossian

Boghossian is a professor of philosophy at New York University. This is a short, well-argued book, although its title is misleading. Its subject is doubt about knowledge or the dismissal of knowledge. The idea that anyone is afraid of knowledge is only mentioned once on the next to last page.

Boghossian’s main target is constructivism: the idea that “knowledge is constructed by societies in ways that reflect their contingent social needs and interests”. He points out that constructivism comes in different varieties. The benign version simply notes that we gather knowledge about topics we’re interested in or need to investigate. He is concerned with versions that lead people, often academics, to say that no group’s or culture’s beliefs are more valid or accurate than anyone else’s. From the epilogue:

There look to be severe objections to each and every version of constructivism about knowledge that we have examined. A constructivism about truth is incoherent. A constructivism about justification is scarcely any better. And there seem to be decisive objections to the idea that we cannot explain belief through epistemic reasons alone.

On the positive side, we failed to find any good arguments for constructivist views…. At its best, … social constructivist thought exposes the contingency of those of our social practices which we had wrongly come to regard as naturally mandated. It does so by relying on the standard canons of good scientific reasoning. It goes astray when it aspires to become a general theory of truth or knowledge. The difficulty lies in understanding why such generalized applications of social construction have come to tempt so many.

He believes that the appeal of constructivism is mainly political, although misguided:

Constructivist views of knowledge are closely linked to such progressive movements as post-colonialism and multiculturalism because they supply the philosophical resources with which to protect oppressed cultures from charges of holding false or unjustified views. [But] if the powerful can’t criticize the oppressed, because the central epistemological categories are inexorably tied to particular perspectives, it also follows that the oppressed can’t criticize the powerful.

Apparently, Boghossian doesn’t recognize the appeal of oppressed groups being on an equal footing with the powerful (“your views are merely a matter of perspective and no more valid than ours”). He concludes:

The intuitive view is that there is a way things are that is independent of human opinion, and that we are capable of arriving at belief about how things are that is objectively reasonable, binding on anyone capable of appreciating the relevant evidence regardless of their social or cultural perspective. Difficult as these notions may be, it is a mistake to think that recent philosophy has uncovered powerful reasons for rejecting them.

What We Have In Mind (Consciousness Again)

Last week, I suggested that consciousness is a type of brain activity, the kind that consists in having a phenomenal field that includes sights, sounds, pains and the internal monologue depicted by authors as the “stream of consciousness”.

I also recommended that we reserve the phrase “conscious of” for the most important things we’re conscious of, things like our everyday surroundings, our feelings and our thoughts, not consciousness itself. This approach would rule out questions like “Are you conscious of consciousness?” that to me seem misguided and misleading. I don’t think we’re conscious of consciousness, but rather conscious of other things.

To say that we’re conscious “of” other things is to say that the components of consciousness represent other things. Thus, some of the brain activity that is consciousness represents things outside our bodies (e.g. trees falling in the forest). Some of it represents things inside our bodies (e.g. heartburn). And some represents things that exist neither inside nor outside our bodies: abstract things like possibilities (e.g. sanity in Washington), fictional characters (Wonder Woman) and ideas (justice or the number twelve).

From an article about dreaming, which is usually considered a kind of consciousness:

One of the main functions of our brain is to constantly create a model of the world around us, a sort of virtual reality that helps us interact with our environment.

When we’re awake, that model is heavily influenced by what we are seeing and hearing and feeling. But during sleep, when there’s not much input from our senses, the brain’s model of the world is more likely to rely on internal information, like memories or expectations.

I’d add that the model is also a model of the world within us and the abstract world of memory, intention and imagination. But thinking of the model our brains create as “a sort of virtual reality” is what I have in mind (that’s a pun). It’s the “sort” of virtual reality that isn’t virtual, however. Patterns of neural activation in the brain (what the model is made of) are quite real. And it’s a model or representation of other things that are quite real too, like falling trees and sprained ankles.

One of the things that makes our conscious model interesting is that it includes events and processes that are strictly or primarily mental, like having a premonition. I don’t know if such things are representations of unconscious mental events and processes. Maybe they aren’t representations at all; maybe they’re patterns of neural activation that don’t refer to or represent anything else. But the evidence suggests that we all have a lot of unconscious brain activity that plays a very large role in what we think and how we feel.

So it would be consistent with the view I’m trying to explain that when you have something like a premonition, what you’re conscious of is a representation of the underlying brain activity (the unconscious premonition processing), as well as any related events in your body (like chills).

To sum up, the position I’ve arrived at seems to be a strange, possibly ridiculous mixture of ideas associated with two great philosophers who are generally seen as opponents: the idealist George Berkeley and the materialist Thomas Hobbes.

Berkeley (1685-1753) argued that nothing exists independently of minds: “To be is to be perceived (or to perceive)”. A person is an immaterial mind or soul. The physical world (the Earth, for example) doesn’t exist independently of our minds. Fortunately, our individual minds are able to get along because God (a kind of super-mind) synchronizes our perceptions. He makes sure that when I perceive a red apple (in my mind), you do too.

Hobbes (1588-1679) argued that nothing exists except physical stuff. We human beings, including our minds, are material things. Even God may be a kind of material being. When I see a red apple, and you see a red apple, therefore, it’s because there’s an apple out there and it’s red. That’s the whole story. 

Where I’ve ended up is to agree with Berkeley that our consciousness has the various elements in it that he called “perceptions” and “ideas”. But I agree with Hobbes that consciousness is a physical phenomenon, a very cool physical phenomenon, but a physical one just the same. And the reason my perceptions usually line up with yours so nicely is because our perceptions represent the same physical world, albeit observed from our individual perspectives.Â
