Philosophy is never too far from physics. It is in their overlap that I expect breakthroughs.

Faster than Light

CERN has published news about some subatomic particles exceeding the speed of light, according to BBC and other sources. If confirmed true, this will remove the linchpin of modern physics — it is hard to overstate how revolutionary this discovery would be to our collective understanding of world we live in, from finest structure of matter to the time evolution of the cosmos. My own anarchical mind revels at the thought of all of modern physics getting rewritten, but I also have a much more personal stake in this story. I will get to it later in this series of posts. First, I want to describe the backdrop of thought that led to the notion that the speed of light could not be breached. The soundness of that scientific backdrop (if not the actual conclusion about the inviolability of light-speed) makes it very difficult to forgo the intellectual achievements of the past one hundred years in physics, which is what we will be doing once we confirm this result. In my second post, I will list what these intellectual achievements are, and how drastically their form will have to change. The scientists who discovered the speed violation, of course, understand this only too well, which is why they are practically begging the rest of the physics community to find a mistake in this discovery of theirs. As it often happens in physics, if you look for something hard enough, you are sure to find it — this is the experimental bias that all experimental physicists worth their salt are aware of and battle against. I hope a false negation doesn’t happen, for, as I will describe in my third post in this series, if confirmed, this speed violation is of tremendous personal importance to me.

The constancy (and the resultant inviolability) of the speed of light, of course, comes from Einstein’s Special Theory of Relativity, or SR. This theory is an extension of a simple idea. In fact, Einstein’s genius is in his ability to carry a simple idea to its logically inevitable, albeit counter-intuitive (to the point of being illogical!) conclusion. In the case of SR, he picks an idea so obvious — that the laws of physics should be independent of the state of motion. If you are in a train going at a constant speed, for instance, you can’t tell whether you are moving or not (if you close the windows, that is). The statement “You can’t tell” can be recast in physics as, “There is no experiment you can device to detect your state of motion.” This should be obvious, right? After all, if the laws kept changing every time you moved about, it is as good as having no laws at all.

Then came Maxwell. He wrote down the equations of electricity and magnetism, thereby elegantly unifying them. The equations state, using fancy vector notations, that a changing magnetic field will create an electric field, and a changing electric field will create a magnetic field, which is roughly how a car alternator and an electric motor work. These elegant equations have a wave solution.

The existence of a wave solution is no surprise, since a changing electric field generates a magnetic field, which in turn generates an electric field, which generates a magnetic filed and so on ad infinitum. What is surprising is the fact that the speed of propagation of this wave predicted by Maxwell’s equations is c, the speed of light. So it was natural to suppose that light was a form of electromagnetic radiation, which means that if you take a magnet and jiggle it fast enough, you will get light moving away from you at c – if we accept that light is indeed EM wave.

What is infinitely more fundamental is the question whether Maxwell’s equations are actually laws of physics. It is hard to argue that they aren’t. Then the follow-up question is whether these equations should obey the axiom that all laws of physics are supposed to obey — namely they should be independent of the state of motion. Again, hard to see why not. Then how do we modify Maxwell’s equations such that they are independent of motion? This is the project Einstein took on under the fancy name, “Covariant formulation of Maxwell’s equations,” and published the most famous physics article ever with an even fancier title, “On the Electrodynamics of Moving Bodies.” We now call it the Special Theory of Relativity, or SR.

To get a bit technical, Maxwell’s equations have the space derivatives of electric and magnetic fields relating to the time derivatives of charges and currents. In other words, space and time are related through the equations. And the wave solution to these equations with the propagation speed of c becomes a constraint on the properties of space and time. This is a simple philosophical look on SR, more than a physics analysis.

Einstein’s approach was to employ a series of thought experiments to establish that you needed a light signal to sync clocks and hypothesize that the speed of light had to be constant in all moving frames of reference. In other words, the speed of light is independent of the state of motion, as it has to be if Maxwell’s equations are to be laws of physics.

This aspect of the theory is supremely counter-intuitive, which is physics lingo to say something is hard to believe. In the case of the speed of light, you take a ray of light, run along with it at a high speed, and measure its speed, you still get c. Run against it and measure it — still c. To achieve this constancy, Einstein rewrote the equations of velocity addition and subtraction. On consequence of these rewritten equations is that nothing can go faster than light.

This is my long-winded description of the context in which the speed violation measured at OPERA has to be seen. If the violation is confirmed, we have a few unpleasant choices to pick from:

  1. Electrodynamics (Maxwell’s equations) is not invariant under motion.
  2. Light is not really electromagnetic in nature.
  3. SR is not the right covariant formulation of electrodynamics.

The first choice is patently unacceptable because it is tantamount to stating that electrodynamics is not physics. A moving motor (e.g., if you take your electric razor on a flight) would behave differently from a static one (you may not be able to shave). The second choice also is quite absurd. In addition to the numeric equality between the speed of the waves from Maxwell’s equations and the measured value of c, we do have other compelling reasons why we should believe that light is EM waves. Radio waves induce electric signals in an antenna, light knocks of electrons, microwaves can excite water molecules and cook food and so on.

The only real choice we are left with is the last one — which is to say SR is wrong. Why not discard SR? More reasons than a blog post can summarize, but I’ll try to summarize them any way in my next post.

What is Unreal Blog?

Tell us a little about why you started your blog, and what keeps you motivated about it.

As my writings started appearing in different magazines and newspapers as regular columns, I wanted to collect them in one place — as an anthology of the internet kind, as it were. That’s how my blog was born. The motivation to continue blogging comes from the memory of how my first book, The Unreal Universe, took shape out of the random notes I started writing on scrap books. I believe the ideas that cross anybody’s mind often get forgotten and lost unless they are written down. A blog is a convenient platform to put them down. And, since the blog is rather public, you take some care and effort to express yourself well.

Do you have any plans for the blog in the future?

I will keep blogging, roughly at the rate of one post a week or so. I don’t have any big plans for the blog per se, but I do have some other Internet ideas that may spring from my blog.

Philosophy is usually seen as a very high concept, intellectual subject. Do you think that it can have a greater impact in the world at large?

This is a question that troubled me for a while. And I wrote a post on it, which may answer it to the best of my ability. To repeat myself a bit, philosophy is merely a description of whatever intellectual pursuits that we indulge in. It is just that we don’t often see it that way. For instance, if you are doing physics, you think that you are quite far removed from philosophy. The philosophical spins that you put on a theory in physics is mostly an afterthought, it is believed. But there are instances where you can actually apply philosophy to solve problems in physics, and come up with new theories. This indeed is the theme of my book, The Unreal Universe. It asks the question, if some object flew by faster than the speed of light, what would it look like? With the recent discovery that solid matter does travel faster than light, I feel vindicated and look forward to further developments in physics.

Do you think many college students are attracted to philosophy? What would make them choose to major in it?

In today’s world, I am afraid philosophy is supremely irrelevant. So it may be difficult to get our youngsters interested in philosophy. I feel that one can hope to improve its relevance by pointing out the interconnections between whatever it is that we do and the intellectual aspects behind it. Would that make them choose to major in it? In a world driven by excesses, it may not be enough. Then again, it is world where articulation is often mistaken for accomplishments. Perhaps philosophy can help you articulate better, sound really cool and impress that girl you have been after — to put it crudely.

More seriously, though, what I said about the irrelevance of philosophy can be said about, say, physics as well, despite the fact that it gives you computers and iPads. For instance, when Copernicus came up with the notion that the earth is revolving around the sun rather than the other way round, profound though this revelation was, in what way did it change our daily life? Do you really have to know this piece of information to live your life? This irrelevance of such profound facts and theories bothered scientists like Richard Feynman.

What kind of advice or recommendations would you give to someone who is interested in philosophy, and who would like to start learning more about it?

I started my path toward philosophy via physics. I think philosophy by itself is too detached from anything else that you cannot really start with it. You have to find your way toward it from whatever your work entails, and then expand from there. At least, that’s how I did it, and that way made it very real. When you ask yourself a question like what is space (so that you can understand what it means to say that space contracts, for instance), the answers you get are very relevant. They are not some philosophical gibberish. I think similar paths to relevance exist in all fields. See for example how Pirsig brought out the notion of quality in his work, not as an abstract definition, but as an all-consuming (and eventually dangerous) obsession.

In my view, philosophy is a wrapper around multiple silos of human endeavor. It helps you see the links among seemingly unrelated fields, such as cognitive neuroscience and special relativity. Of what practical use is this knowledge, I cannot tell you. Then again, of what practical use is life itself?

Dualism

After being called one of the top 50 philosophy bloggers, I feel almost obliged to write another post on philosophy. This might vex Jat who, while appreciating the post on my first car, was somewhat less than enthusiastic about my deeper thoughts. Also looking askance at my philosophical endeavors would be a badminton buddy of mine who complained that my posts on death scared the bejesus out of him. But, what can I say, I have been listening to a lot of philosophy. I listened to the lectures by Shelly Kagan on just that dreaded topic of death, and by John Searle (again) on the philosophy of mind.

Listening to these lectures filled me with another kind of dread. I realized once again how ignorant I am, and how much there is to know, think and figure out, and how little time is left to do all that. Perhaps this recognition of my ignorance is a sign of growing wisdom, if we can believe Socrates. At least I hope it is.

One thing I had some misconceptions about (or an incomplete understanding of) was this concept of dualism. Growing up in India, I heard a lot about our monistic philosophy called Advaita. The word means not-two, and I understood it as the rejection of the Brahman and Maya distinction. To illustrate it with an example, say you sense something — like you see these words in front of you on your computer screen. Are these words and the computer screen out there really? If I were to somehow generate the neuronal firing patterns that create this sensation in you, you would see these words even if they were not there. This is easy to understand; after all, this is the main thesis of the movie Matrix. So what you see is merely a construct in your brain; it is Maya or part of the Matrix. What is causing the sensory inputs is presumably Brahman. So, to me, Advaita meant trusting only the realness of Brahman while rejecting Maya. Now, after reading a bit more, I’m not sure that was an accurate description at all. Perhaps that is why Ranga criticized me long time ago.

In Western philosophy, there is a different and more obvious kind of dualism. It is the age-old mind-matter distinction. What is mind made of? Most of us think of mind (those who think of it, that is) as a computer program running on our brain. In other words, mind is software, brain is hardware. They are two different kinds of things. After all, we pay separately for hardware (Dell) and software (Microsoft). Since we think of them as two, ours is an inherently dualistic view. Before the time of computers, Descartes thought of this problem and said there was a mental substance and a physical substance. So this view is called Cartesian Dualism. (By the way, Cartesian coordinates in analytic geometry came from Descartes as well — a fact that might enhance our respect for him.) It is a view that has vast ramifications in all branches of philosophy, from metaphysics to theology. It leads to the concepts of spirit and souls, God, afterlife, reincarnation etc., with their inescapable implications on morality.

There are philosophers who reject this notion of Cartesian dualism. John Searle is one of them. They embrace a view that mind is an emergent property of the brain. An emergent property (more fancily called an epiphenomenon) is something that happens incidentally along with the main phenomenon, but is neither the cause nor the effect of it. An emergent property in physics that we are familiar with is temperature, which is a measure of the average velocity of a bunch of molecules. You cannot define temperature unless you have a statistically significant collection of molecules. Searle uses the wetness of water as his example to illustrate emergence of properties. You cannot have a wet water molecule or a dry one, but when you put a lot of water molecules together you get wetness. Similarly, mind emerges from the physical substance of the brain through physical processes. So all the properties that we ascribe to mind are to be explained away as physical interactions. There is only one kind of substance, which is physical. So this monistic philosophy is called physicalism. Physicalism is part of materialism (not to be confused with its current meaning — what we mean by a material girl, for instance).

You know, the trouble with philosophy is that there are so many isms that you lose track of what is going on in this wild jungle of jargonism. If I coined the word unrealism to go with my blog and promoted it as a branch of philosophy, or better yet, a Singaporean school of thought, I’m sure I can make it stick. Or perhaps it is already an accepted domain?

All kidding aside, the view that everything on the mental side of life, such as consciousness, thoughts, ideals etc., is a manifestation of physical interactions (I’m restating the definition of physicalism here, as you can see) enjoys certain currency among contemporary philosophers. Both Kagan and Searle readily accept this view, for example. But this view is in conflict with what the ancient Greek philosophers like Socrates, Plato and Aristotle thought. They all believed in some form of continued existence of a mental substance, be it the soul, spirit or whatever. All major religions have some variant of this dualism embedded in their beliefs. (I think Plato’s dualism is of a different kind — a real, imperfect world where we live on the one hand, and an ideal perfect world of forms on the other where the souls and Gods live. More on that later.) After all, God has to be made up of a spiritual “substance” other than a pure physical substance. Or how could he not be subject to the physical laws that we, mere mortals, can comprehend?

Nothing in philosophy is totally disconnected from one another. A fundamental stance such as dualism or monism that you take in dealing with the questions on consciousness, cognition and mind has ramifications in what kind of life you lead (Ethics), how you define reality (Metaphysics), and how you know these things (Epistemology). Through its influence on religions, it may even impact our political power struggles of our troubled times. If you think about it long enough, you can connect the dualist/monist distinction even to aesthetics. After all, Richard Pirsig did just that in his Zen and the Art of Motorcycle Maintenance.

As they say, if the only tool you have is a hammer, all problems begin to look like nails. My tool right now is philosophy, so I see little philosophical nails everywhere.

How to be a Good Parent

Looking back at how I brought up my children (or, how I have been doing it, for they are still children), I have mixed feelings about how good I have been as a parent. Overall, I have been decent, slightly above average, I guess. But I have certainly formed strong opinions about what it means to be a good parent. I want to share my thoughts with my younger readers in the hope that they may find something useful in it.

In most things we do, there is a feedback, and we can use the feedback improve ourselves. For instance, if we do poorly at work, our bonuses and paychecks suffer, and we can, if we want to, work harder or smarter to remedy the situation. In our dealings with our children, the feedback is very subtle or even absent. We have to be very sensitive and observant to catch it. For instance, when my daughter was less than a year old, I noticed that she wouldn’t make eye contact when I came back late from work or when her mother came back from a business trip. To this day, I am not entirely sure that it was an expression of disapproval on her part, or fanciful imagination on mine.

Even when the children are old enough to articulate their thoughts, their feedback is often subtle to non-existent because they don’t know how to judge us, the parents. You see, they have no yardstick, no standards by which to assess our parenting qualities. We are the only parents they will ever have and, for all our follies, it is very hard for them to find any faults with us. So we have to measure up to a much higher standard — our own.

Coupled with this unvoiced feedback is the huge sense of injustice that our little unfairnesses can inflict on our children’s little hearts. As Dickens said in one of his books, small injustices loom large in the small world of a child. (I am sure he put it a lot better; I am paraphrasing.) We have to appreciate the need to be painstakingly and scrupulously fair with our children. I am not talking about being fair between children, but between us and a child. Don’t hold them to rules that you are not willing to live by. These rules can be small — like don’t watch TV while eating. If you like your TV with your dinner, don’t expect the kids to stick to the dining table. They do what we do, not always what we say.

In fact, imitating our habits and mannerisms is part of their charm for us. By nature and nurture, our kids mirror our looks and actions. If we don’t like what we see in the mirror and complain about it, we are often barking up the wrong tree. In order to improve the image, we have to improve ourselves. We have to live up to a high level of integrity and honesty. Nothing else works.

Another essential virtue for a parent is patience. In today’s busy world, with thousands of thoughts and cares and distractions all vying for our attention, it is always a tussle to be, for instance, a good blogger, a good corporate player, a good spouse and, at the same time, a good parent. One way out of this is to dedicate a certain amount of quality time for our parenting Karma. This may be the only practical advice in this post — so pay attention now. Set aside half an hour (or whatever time you can) every day for your little ones. During this time, focus your undivided attention your kids. No TV, no Internet, no phone calls — only you and your kids. If you can do it on a fairly regular basis, your kids will remember you for a long time after you are gone.

Our children are our legacy. They are what we leave behind. And they are, in many ways, our own reflections — our little addition, little pieces of colored glass in the dome of many-colored glass staining the white radiance of eternity. Let’s try to leave behind as perfect a reflection as we can.

Thinking again about all the sermonizing I did in this post, I find that it is not so specific to being a good parent. It is more about being a good person. I guess what they say (in the Zen way of looking at things) is true — how do you paint a perfect painting? Be perfect and then just paint. How to be a good parent? Be good, and then be a parent! Goodness happens in the stillness of perfection and peace where even “bad” things are good. This statement is perhaps mystical enough to wind up this post with.

The Unreal Universe

We know that our universe is a bit unreal. The stars we see in the night sky, for instance, are not really there. They may have moved or even died by the time we get to see them. It takes light time to travel from the distant stars and galaxies to reach us. We know of this delay. The sun that we see now is already eight minutes old by the time we see it, which is not a big deal. If we want to know what is going on at the sun right now, all we have to do is to wait for eight minutes. Nonetheless, we do have to “correct” for the delay in our perception due to the finite speed of light before we can trust what we see.

Now, this effect raises an interesting question — what is the “real” thing that we see? If seeing is believing, the stuff that we see should be the real thing. Then again, we know of the light travel time effect. So we should correct what we see before believing it. What then does “seeing” mean? When we say we see something, what do we really mean?

Seeing involves light, obviously. It is the finite (albeit very high) speed of light influences and distorts the way we see things, like the delay in seeing objects like stars. What is surprising (and seldom highlighted) is that when it comes to seeing moving objects, we cannot back-calculate the same way we take out the delay in seeing the sun. If we see a celestial body moving at an improbably high speed, we cannot figure out how fast and in what direction it is “really” moving without making further assumptions. One way of handling this difficulty is to ascribe the distortions in our perception to the fundamental properties of the arena of physics — space and time. Another course of action is to accept the disconnection between our perception and the underlying “reality” and deal with it in some way.

This disconnect between what we see and what is out there is not unknown to many philosophical schools of thought. Phenomenalism, for instance, holds the view that space and time are not objective realities. They are merely the medium of our perception. All the phenomena that happen in space and time are merely bundles of our perception. In other words, space and time are cognitive constructs arising from perception. Thus, all the physical properties that we ascribe to space and time can only apply to the phenomenal reality (the reality as we sense it). The noumenal reality (which holds the physical causes of our perception), by contrast, remains beyond our cognitive reach.

One, almost accidental, difficulty in redefining the effects of the finite speed of light as the properties of space and time is that any effect that we do understand gets instantly relegated to the realm of optical illusions. For instance, the eight-minute delay in seeing the sun, because we can readily understand it and disassociate it from our perception using simple arithmetic, is considered a mere optical illusion. However, the distortions in our perception of fast moving objects, although originating from the same source are considered a property of space and time because they are more complex. At some point, we have to come to terms with the fact that when it comes to seeing the universe, there is no such thing as an optical illusion, which is probably what Goethe pointed out when he said, “Optical illusion is optical truth.”

More about The Unreal UniverseThe distinction (or lack thereof) between optical illusion and truth is one of the oldest debates in philosophy. After all, it is about the distinction between knowledge and reality. Knowledge is considered our view about something that, in reality, is “actually the case.” In other words, knowledge is a reflection, or a mental image of something external. In this picture, the external reality goes through a process of becoming our knowledge, which includes perception, cognitive activities, and the exercise of pure reason. This is the picture that physics has come to accept. While acknowledging that our perception may be imperfect, physics assumes that we can get closer and closer to the external reality through increasingly finer experimentation, and, more importantly, through better theorization. The Special and General Theories of Relativity are examples of brilliant applications of this view of reality where simple physical principles are relentlessly pursued using the formidable machine of pure reason to their logically inevitable conclusions.

But there is another, competing view of knowledge and reality that has been around for a long time. This is the view that regards perceived reality as an internal cognitive representation of our sensory inputs. In this view, knowledge and perceived reality are both internal cognitive constructs, although we have come to think of them as separate. What is external is not the reality as we perceive it, but an unknowable entity giving rise to the physical causes behind sensory inputs. In this school of thought, we build our reality in two, often overlapping, steps. The first step consists of the process of sensing, and the second one is that of cognitive and logical reasoning. We can apply this view of reality and knowledge to science, but in order do so, we have to guess the nature of the absolute reality, unknowable as it is.

The ramifications of these two different philosophical stances described above are tremendous. Since modern physics has embraced a non-phenomenalistic view of space and time, it finds itself at odds with that branch of philosophy. This chasm between philosophy and physics has grown to such a degree that the Nobel prize winning physicist, Steven Weinberg, wondered (in his book “Dreams of a Final Theory”) why the contribution from philosophy to physics have been so surprisingly small. It also prompts philosophers to make statements like, “Whether ‘noumenal reality causes phenomenal reality’ or whether ‘noumenal reality is independent of our sensing it’ or whether ‘we sense noumenal reality,’ the problem remains that the concept of noumenal reality is a totally redundant concept for the analysis of science.”

From the perspective of cognitive neuroscience, everything we see, sense, feel and think is the result of the neuronal interconnections in our brain and the tiny electrical signals in them. This view must be right. What else is there? All our thoughts and worries, knowledge and beliefs, ego and reality, life and death — everything is merely neuronal firings in the one and half kilograms of gooey, grey material that we call our brain. There is nothing else. Nothing!

In fact, this view of reality in neuroscience is an exact echo of phenomenalism, which considers everything a bundle of perception or mental constructs. Space and time are also cognitive constructs in our brain, like everything else. They are mental pictures our brains concoct out of the sensory inputs that our senses receive. Generated from our sensory perception and fabricated by our cognitive process, the space-time continuum is the arena of physics. Of all our senses, sight is by far the dominant one. The sensory input to sight is light. In a space created by the brain out of the light falling on our retinas (or on the photo sensors of the Hubble telescope), is it a surprise that nothing can travel faster than light?

This philosophical stance is the basis of my book, The Unreal Universe, which explores the common threads binding physics and philosophy. Such philosophical musings usually get a bad rap from us physicists. To physicists, philosophy is an entirely different field, another silo of knowledge, which holds no relevance to their endeavors. We need to change this belief and appreciate the overlap among different knowledge silos. It is in this overlap that we can expect to find great breakthroughs in human thought.

The twist to this story of light and reality is that we seem to have known all this for a long time. Classical philosophical schools seem to have thought along lines very similar to Einstein’s reasonings. The role of light in creating our reality or universe is at the heart of Western religious thinking. A universe devoid of light is not simply a world where you have switched off the lights. It is indeed a universe devoid of itself, a universe that doesn’t exist. It is in this context that we have to understand the wisdom behind the statement that “the earth was without form, and void” until God caused light to be, by saying “Let there be light.”

The Quran also says, “Allah is the light of the heavens and the earth,” which is mirrored in one of the ancient Hindu writings: “Lead me from darkness to light, lead me from the unreal to the real.” The role of light in taking us from the unreal void (the nothingness) to a reality was indeed understood for a long, long time. Is it possible that the ancient saints and prophets knew things that we are only now beginning to uncover with all our supposed advances in knowledge?

I know I may be rushing in where angels fear to tread, for reinterpreting the scriptures is a dangerous game. Such alien interpretations are seldom welcome in the theological circles. But I seek refuge in the fact that I am looking for concurrence in the metaphysical views of spiritual philosophies, without diminishing their mystical and theological value.

The parallels between the noumenal-phenomenal distinction in phenomenalism and the Brahman-Maya distinction in Advaita are hard to ignore. This time-tested wisdom on the nature of reality from the repertoire of spirituality is now being reinvented in modern neuroscience, which treats reality as a cognitive representation created by the brain. The brain uses the sensory inputs, memory, consciousness, and even language as ingredients in concocting our sense of reality. This view of reality, however, is something physics is yet to come to terms with. But to the extent that its arena (space and time) is a part of reality, physics is not immune to philosophy.

As we push the boundaries of our knowledge further and further, we are beginning to discover hitherto unsuspected and often surprising interconnections between different branches of human efforts. In the final analysis, how can the diverse domains of our knowledge be independent of each other when all our knowledge resides in our brain? Knowledge is a cognitive representation of our experiences. But then, so is reality; it is a cognitive representation of our sensory inputs. It is a fallacy to think that knowledge is our internal representation of an external reality, and therefore distinct from it. Knowledge and reality are both internal cognitive constructs, although we have come to think of them as separate.

Recognizing and making use of the interconnections among the different domains of human endeavor may be the catalyst for the next breakthrough in our collective wisdom that we have been waiting for.

Death — Last Words

We all have some genetic logic hard-coded in our DNA regarding death and how to face it — and, much more importantly, how to avoid it. One aspect of this genetic logic perplexes me. It is the meekness with which we seem to face the prospect of death, especially violent death. In violent situations, we seem bent on appealing to the assailant’s better nature to let us be. With apologies to those who may find this reference offensive, I’m thinking of the millions of people who marched quietly into the night during the holocaust, for instance. Given that the end result (death) was more or less guaranteed whether they resisted or not, why didn’t they? Why is there such a motto as “resist no evil”? Why the heck not?

Well, I know some of the answers, but let’s stack some cold and possibly inappropriate logic against these vagaries of our genetic logic. If a Bengal tiger attacks you in a forest, your best chance of survival would be to stand up and fight, I would think. It is possible, though not likely, that the tiger might consider you too much trouble and give up on you. I know the tigerologists out there would laugh at me, but I did say “not likely.” Besides, I have read this story of an Indian peasant who managed to save his friend from a tiger by scaring it off with a stick and a lot of noise. My be the peasant was just lucky that the tiger wasn’t too hungry, nonetheless… Anyhoo, I would have thought the genetic logic in our DNA would reflect this kind of fighting spirit which may improve our survival rate. Appealing to the tiger’s better nature would be somewhat less effective, in my opinion.

A similar meekness is apparent, I reckon, in our follow-the-crowd attitude toward many things in life, including our notion of morality, happiness etc. I suspect these notions are perhaps so complex and taxing to fathom that we let our intellectual laziness overtake our desire to know. My own thinking seems to lead to a dark symphony of aimlessness and lack of ethical values. I am desperately trying to find a happy note in it to wind up this series with.

The “trouble” is that most people are moral, ethical and all-round decent folks, despite the existence of death and their knowledge thereof. It is silly to dismiss it as meekness, lack of intellectual effort etc. There must be some other reason. I don’t think I will be able to find this elusive reason before the end of this series. But I have to conclude that “living everyday as your last” definitely doesn’t help. If anything, it has to be our blissful capacity to ignore death that brings about ethical rectitude. Perhaps the other motto of “living in the present moment” is just that — an appeal to ignore the future where death looms.

Death has the effect of rendering our daily existence absurd, as Sisyphus’s work on rocks. It really does make the notion of existence so absurd as to force one to justify why one should live at all. This dangerous line of thinking is something that every philosopher will have to face up to, at some point. Unless he has some answers, it would be wise to keep his thoughts to himself. I didn’t. But then, very few have accused me of the vice of wisdom.

Does the World Go on?

Notwithstanding the certain rupture in the continuity of consciousness due to death, or a less certain rupture in that of a soul, we have another uninterrupted flow — that of life and of the world. This flow is the end result of a series of projections and perhaps the work of our mirror neurons. Let me explain. We know that the world doesn’t stop just because someone dies. Most of us middle-aged folks have lost a loved one, and, for all the grief, we know that life went on. So we can easily see that when we die, despite all the grief we may succeed in making our loved ones feel through our sheer good deeds, life will go on. Won’t it?

It is our absolute certainty about this continuity that prompts us to buy huge life insurances, and somewhat modulates the risk-reward analysis of our moral actions. I am not going to deny the existence of this continuity, tempted though I am to do just that. I merely want to point out certain facts that may prevent us from accepting it at its face value. The evidence for the world going on after our death is simple, too simple perhaps: We have seen people die; but we live on. Ergo, when we die, other people will live on. But you see, there is a profound difference between somebody else’s death and your death. We are thinking of death as the end of our consciousness or mind. Although I loosely group your mind and my mind as “our” mind in the previous sentence, they are completely different entities. In fact, a more asymmetric system is hard to imagine. The only mind I know of, and will ever know of, is my own. Your mind has an existence only in mine. So the demise of my mind is literally the end of your mind (and indeed all minds) as well. The world does come to an end with my death, quite logically.

This argument, though logical, is a bit formal and unconvincing. It smacks of solipsism. Let’s approach the issue from a different angle. As we did earlier in this essay, let’s think of death as dreamless slumber. If you are in such a state, does the world exist for you? I know the usual responses to this question: Of course it exists; just because you cannot feel it, doesn’t mean that it doesn’t exist. You know it exists, and that is enough. Now, who is this you that knows?

Therein lies the real rub. Once you cease to have a consciousness, be it thanks to sleep or death, you lose the ability to experience everything, including the existence of anything (or lack thereof). Now, we can take the normal approach and just assert that things have an existence independent of your experiencing it; that would the natural, dualistic view — you and everything else, your experiences and their physical causes, cause and effect, action and reaction, and so on. Once you begin to doubt the dualistic worldview and suspect that your experiences are within your consciousness, and that the so-called physical causes are also your cognitive constructs, you are on a slippery slope toward another worldview, one that seriously doubts if it makes any sense to assert that the world goes on after your death.

The world is merely a dream. What sense could a dead man’s dream possibly make?

Primal Soul

One simple way of reinstating an absolute form of morality (as opposed to a relative, risk-reward kind) is to postulate continuity beyond death. The notion of a “soul,” as proposed in almost all religions, serves this purpose. Soul is also the substantive (albeit ethereal) representation of the otherwise elusive consciousness of ours, which is an entity that has no right to exist or be real because it fails all possible tests for real existence, yet is supremely real to each one of us. In fact, consciousness is more than real, it is the arena in which our reality plays out its act. It is so fundamental to our experience and existence that we have a hard time accepting its ephemerality.

I, for one, believe logically that when I die, everything I will have known and experienced till then will just disappear. I believe that death is like an eternal dreamless sleep. Logically. But logic has very little to do with what I can feel and accept, emotionally. I don’t like to drag in the concept of “emotion” here; I am thinking of what I can accept at a gut-level. “Primally” would perhaps be a better word to use, but I am not sure. Any way, once we have conscious awareness, and develop a sense of temporal continuity about things and experiences around us, we cannot help assigning continuity to the backdrop of it all — our consciousness. Continuity of selfhood is encoded into our mind. Primally — yes, that would be the right word.

Logic and rationality, which come after the primal plumbing of the mind, consciousness, selfhood etc. (which may all ultimately mean the same thing) is already in place, can influence our thinking only to a limited extent. Mind grasps at anything that offers a semblance of eternal continuity. Enter religions.

All conventional religions have some notion of a “soul,” which comes in different forms and with a multitude of meanings and contexts, although, logically, it can only mean our consciousness, or an entity holding our consciousness and pretty much nothing else. Thanks to our primal need to search and find continuity, we readily buy into whatever notion of soul our parents’ religion happens to uphold, ignoring the gaping holes in logic associated with it. From the perspective of religions (speaking of religions as organizational entities with intentions and purposes), the notion of continuity implied in the concept of a soul has a great benefit — it completely alters the risk-reward analysis at the root of morality. And it takes out death (or at least, greatly diminishes its significance) in the analysis. For death is only the beginning, as the horror-comedy taught us.

If the wages of sin are eternal third-degree burns, not some material comfort followed by thirty-to-life in a federal facility till death sets you free, you do think twice before doing the crime. The “time” that you may have to do could well be an eternity. Other religions offer other kinds of divine carrots and sticks. For instance, if you are a Hindu engaged in a particularly unsavory Karma, you will reincarnate as somebody (or something) on the receiving end of the stick, roughly neutralizing your risk-reward equation. On the other hand, if you are willing to take it on your chin with some amount of fortitude, you will be upgraded to business class in your next life.

In all notions of spiritual continuity of consciousness, and/or soul, there is something I find logically wanting. It is the lack of continuity of memory. Death is still a point of phase transition where all the existing memory is erased. If we think of soul as the eternal manifestation of mind and consciousness, erasing its memory is as good or as bad as killing it, is it not?

What I find interesting in this Hindu notion is that the ultimate reward for presumably the best possible Karma is not an eternal life of comfort in heaven, but a release from the cycle of reincarnations, which, in my view, is similar to an eternal dreamless sleep — which is the only logical notion of death we can scientifically entertain. So, in the Hindu notion of the reward for ultimate good is, in some sense, the ultimate death. Makes me wonder…

From Here to Eternity

The temporal aspect of punishment extends beyond the span between the crime and its punishment. The severity of the punishment is also measured in terms of its duration. And death puts a definitive end to all man-made durations. This interference of death in our temporal horizons messes up what we mean by proportional punishment, which is the reason behind the general lack of gratification on Madoff’s long sentence. If a heinous crime like a senseless murder brings about only a life-sentence, and if you know that “life” means only a couple of months or so, then the punishment in and of itself is incapable of deterring the crime. And when the crime is not as senseless, but prompted by careful material considerations, it is a deliberate risk-reward analysis that determines its commission. A comprehensive risk-reward analysis would involve, I imagine, a consideration of the probability of detection, the intensity and duration of the potential punishment, and the time one has to enjoy the spoils and/or suffer the punishment. There may be other factors to consider, of course. I wouldn’t know because I haven’t actually done such analyses. Not yet.

The smallpox story I mentioned earlier brings these considerations to the foreground, along with how the relatively high probability of death from the disease affects them. Knowing that there isn’t much time to enjoy life (or face the music), two older gentlemen of the story decide to go and feast themselves on a local prostitute of the village whom they have been eying for a while. It is not that the consequences (spousal anger, bad diseases etc.) of their action have changed. Just that their potential duration has decreased drastically because of the outbreak of smallpox. Knowledge of our death has a dramatic effect on our moral inhibitions born out of risk-reward analyses.

It is in this light that we have to examine clichéd statements like, “Live in the present moment,” or “Live everyday as though it is your last.” What do these statements really mean? The second one is especially interesting because it makes a direct reference to death. Is it asking us to shed our inhibitions vis-à-vis all our actions? If so, it may not be such a positive invitation (which, of course, is a statement of value-judgment emanating form a sense of a morality of unknown origins). Or it could be a simple exhortation not to procrastinate — a positive thing by the same uncertain morality.

“Living in the present” is even more puzzling. I guess it comes from the Zen notion of “here” and “now.” I can kind of understand the Zen notion in terms of cognitive neuroscience, although that is the sort of thing that Zen would ask us not to do — understanding one thing in terms of something else. According to the Zen school, an experience has to be assimilated before the intellect has a chance to color it in terms of preconceived notions and filters. In the absolute stillness of a mind, presumably brought about by years of introspection and intense mediation, experiences take on perceptually accurate and intellectually uncolored forms, which they say is a good thing. If the statement “Live in the present moment” refers to this mode of experiencing life, fine, I can go with that, even though I cannot fully understand it because I am not a Zen master. And if I was, I probably wouldn’t worry too much about logically understanding stuff. Understanding is merely a misguided intellectual exercise in futility.

As a moral statement, however, this invitation to live in the present moment leaves much to be desired. Is it an invitation to ignore the consequences of your actions? You compartmentalize your timeline into a large past, a large future and tiny present. You ignore the past and the future, and live in the present. No regrets. No anxieties. What else could this slogan “Live in the present moment” mean?
