The Disease behind the Symptom


In the last 4-5 years, we have employed 5-6 domestic helps. Alcoholism has killed the husbands of two of them. At least 4 of them suffered serious domestic and financial issues due to their husbands being alcoholic.
These questions are hurting me today:

  • What may be the overall damage (in rupees) that alcohol may be doing to our economy?
  • Dismissing them as drunkards is alright. But what insurmountable ignorance, frustration and deprivation stifles their ability to see how self-destructing the habit is.
  • If the wish to not see a slightly smarter phone, a slightly bigger salary, car or house, a bit costlier dresses and jewels with a friend has the potential to drive us to insane levels of competitive activity, what may living in abject poverty right next to the pomp and show of a consumerist mainstream be doing to the morale of these underdogs?

I would just like to broaden it a bit further and stop just when it may start sounding a bit in variance to the tone of fashionable intellect of today. Why is it such a taboo today to talk about the problem that the moment you are out on the streets, it's impossible not to let it become a show off your possessions to a deprived? Probably, there's nothing we can do about it. But we can't wish the problem away.

Seeing other's possessing anything of desire causes pangs of jealousy. Years and years of trying to bear that pain is bound to result in pathological behaviour.

Jealousy is the disease we all suffer from. Some of us have the material possessions so the symptoms don't show up in us. It's not us and they. We all have the germs of this disease in our very make.

Hampi Heat

A Water colour sketch of the Paddy Fields near our Guest House
A quick one here about our recent trip to Hampi.

Getting There and Staying

Stayed two days in a nearby village called Sanapur. Beautiful serene place. Isolated. And surrounded by lush paddy fields and majestic rocky mountains.
Paddy Fields and Rocky Mountains


Lodged at Gowri Guest House. More of a budget place with a reasonably good lodging service and excellent homely food.
Gowri Guest House


Why would you prefer this place? Firstly, Sanapur is not exactly Hampi. It's across the Tungabhadra river. So costs are a bit lower here hopefully. Secondly, the place is full of attractive tourist spots. So, a day loitering around in the neighbouring locales -- particularly the village Anegundi -- is not at all a bad idea.
Hampi from across the River

However, if you do choose to stay across Tungabhadra, here's a word of caution. Getting here from Hospet (which is the nearest railway station, and would probably be your disembarking point) is a breeze during the day. Just take a conveyance to Hampi, and cross the river using the ferry. However, God forbid, if you land up in Hospet at night, you are as good as dead. Ferries stop in the night. So, you have to take a very circuitous and scary ride through dark, deserted stretches to get to Sanapur. And if that misadventure doesn't drill a hole in your pocket, you should consider yourself lucky.

So, here's the bottomline. If staying in Sanapur and coming via Hospet, choose to arrive during the day. If arriving at night, stay put in Hospet.

So, our first day was spent on the other side of Tungabhadra. We saw the following places:
  1. Sanapur Lake: An artificial lake created with the backwaters of Tungabhadra Dam.
  2. Rishimukh Temple: An ancient, very dilapidated and abandoned temple on the spot which is said to be the meeting point of Lord Rama and Shugriva, the monkey king.
  3. Anjaneya Parvat: The alleged birthplace of Hanuman, the monkey god.
  4. Pampa Sarover: The place where, the old lady Shabari had played host to Lord Rama and Lakshmana.
  5. Ranganath Swamy Temple
  6. A Nearby Cottage Industry making very interesting products out of banana tree parts: Essential visit for shopping for curios and seeing some excellent craftmanship.
  7. Chintamani Temple: The spot where Lord Rama is supposed to have killed Vaali, Sugriva's brother.


The second day was spent in Hampi proper. In fact I don't find it important to list down the spots which are very well known and documented about. Here are a few tips which may be practically helpful.

If you book a auto-rickshaw for the day (which we did), you will be done in less than Rs. 1000. The rickshaw driver may act as a stand in for a guide, though a poor one.
Taking a guide for the day is generally supposed to be a good idea. We didn't though. So, I can't say. I have a perception that guides tend to sensationalise a lot, and mayn't give an accurate account of things. A guide can be hired for the entire day for about Rs. 600. There are trained and authorised guide available from the Tourism department.
The poor man's/scholar's option is to read up a priori, and carry notes if required. There are books available on-site which are somewhat overpriced but of reasonable quality. Doesn't hurt to buy one.

Climate

Hampi is really hot. All those rocks around (whether sculpted or not) add to the heat. Even in October, the heat was sweltering. Of course, the common way out is to visit in season, which is between December to March or something. But then, it's costly and crowded at that time. So, a poor man's alternative: visit at other times of the year, but protect yourself against the heat. It's not crowded at other times, which is a great plus. Drink a lot of water and coconut water. Take rest. Wear caps and goggles. Use sunscreen lotions, but be OK with getting tanned and sunburned. Make sure you are in a reasonable fitness level.

To put your mind at rest, my 4 year old son braved the heat beautifully without ever complaining. With even a modest amount of eye for aesthetics (which, happily and surprisingly, my little son seems to have even at this little age),  the beauty of the place is going to be the predominating component of your experience. So, don't worry!
Vigyan enthusiastically climbed the 600 steps to the Anjaneya Temple all by himself in the scorching midday heat
Cooling our feet in Tungabhadra water

Visit Again!

As, I assume, there's plenty available out there to read about the beauty of Hampi, I won't go into that. All I have to add is that it's a place which deserves to be visited again and again. I am sure with more knowledge about the glorious history of the Vijayanagara empire that those broken remains continually whisper in your ears while you are there, every subsequent visit is bound to be richer and richer in experiences.

As for me, I have resolved to visit again. And very soon!

Love Reciprocated

Beloved, Nature, the world, Universe, Work, Life -- they all seem to say the same thing: 'If you wish to own me, give yourself up completely to me.' Are they mere messengers of someone else?

Off to School



Another new-found pleasure of life: seeing off son to school. Every morning between 7.45 to 8, there's a huge racket at the gate of our apartment complex. Kids and their parents waiting for the school buses. Kids are all bubbling with energy and joy on seeing their playmates. There are handing over school bags, water bottles, lunch boxes. Late comers rushing in at the last minute. 'Byes' and hugs and kisses when the tiny-tots huddle into the buses. Occasionally, some of them (Vigyan included) become a little sentimental and get a bit teary eyed. But just for a brief moment. The energy infects most parents. After seeing their kids get into their buses, parents return home or start off to office. Most are carrying a smile they got from their kids.

What a brilliant way to give such a positive start to the day! :)

Birthday 2013

Yesterday was a very special birthday.

Firstly, my friend Pritesh ordered a beautiful cake for me which was the shape of a study table. On top of it were all things I (used to) spend my time with: writing pad, drawing material, ramen noodles, coffee and so on. Thanks Pritesh! For remembering, and personalising the gift to the extent only a true friend and a true artist can do. As many thanks are due to Sathya! He drove to Malleswaram at 6 AM to collect the cake and was at my house at 7.30 AM. Never was someone so fortunate as I am to have an ace musician and friend playing the delivery boy! :) Sathya! Thanks, man! I must also thank Itsy Bitsy Bytes who made the lovely cake. Lovely work of art!

Cake presented by Pritesh, delivered by Sathya, and made by Itsy Bitsy Bytes

Yesterday was convocation day in IIITB. So, I was there at the institute by 9 in the morning, all dressed up. Then came the next pleasant surprise. Our director, Prof. Sadagopan, in the midst of all the business of preparation of the grand convocation ceremony, had remembered to order a cake for me. And I cut the cake in his very office in the presence of people like Mrs. Sudha Murthy and other important dignitaries.

Post-dinner tea isn't encouraged by my dear wife. However, yesterday, an exception was made, and I was served a cup of delicious hot tea after my dinner. And Shilpi topped it up by having tea herself, and sitting (alone with me) chatting for over an hour -- a prized treat for me!

I am thankful for having made it this far. For having had a life which makes me have more and more of it. For having people in my life who love and appreciate me as I am. And those who keep the excitement up by making me want to learn something new everyday.

I'll stop before it starts sounding like the vote-of-thanks speech I delivered yesterday in the convocation. :)

What Have You Learned So Far?

Often, I suffer from this sudden feeling -- almost like a panic attack -- of blankness. I ask myself the question: 'What have you learnt so far?' And I can't remember anything that I consider worth a mention. Most of the things I seem to know appear too easy, too natural, too unavoidable for me to have learned. As if the gravity of my destiny took me through a path I didn't decide for myself. Whatever learning that happened seem to be dust on the road that stuck to my feet. Most importantly, the context in which I can demonstrate my mastery of any subject, or their applicability to an important problem, are ridiculously specialised and elaborate.

Language? What except a few grammatical constructs, a lexicon of memorised words, a cunning (not-so-respectable) insight into idioms -- what sounds fashionable and appropriate?
Art? Ha! What are you, man?
Math and Science? Try to remember one thing useful you have succeeded in doing with your knowledge in science.
Programming? What but a few ifs, and elses, and brackets and semicolons? How many people have used the programs you have written?
Engineering? What have you built or fixed with your own hands so far?
Worldly knowledge? Look at the shabby, absent-minded, nervous misfit that you are!
Philosophy and Spirituality? How many of the millions of seconds you have lived were truly truly blissful, by the way?

Please don't equate the above feeling with a feeling of worthlessness. I don't feel worthless at all. For example, there are many worthwhile things I have learnt to do: to make the bed, to do the laundry and grocery, drive family and friends around in my car/2-wheeler, purchasing travel/movie-tickets online, entertain people by chit-chatting and cracking non-sense jokes. So, I don't suffer from any feeling of worthlessness. It's just that, there are these moments when I feel seriously doubtful if any of the things I like to call my learning or education or whatever has added even a penny of worth into my real life. My education allows me to shuttle around in various professional positions, some of which are at least so-called respectable and/or somewhat high-paying: a good vehicle of subsistence. They allow me to spin out conversations which sound wise at times. I can boast of knowing probably 20 programming languages in which I can write hardly anything more significant than 'Hello world!' programs. I know 6-7 natural languages in which the most complex communication I am probably able to do is that of my inadequate knowledge of that language: 'kannada gottila!'  (I don't know kannada)

Part of the above state of mind is surely due to my somewhat low-in-confidence personality. Part of it is probably due to my lack of comprehension of how complex the world and the life is so that I even start expecting to see a direct consequence of my learning attaining some sort of a closure on my and others' lives.

But a major part of it -- I have recently realised -- is due to my own forgetfulness. I seem to have somehow forgotten how much struggle it's been to learn whatever I know -- however trivial and inconsequential it might be in the big scheme of things.

I have enjoyed some recent opportunities of teaching youngsters things that my CV says that I might be knowing something about. Math, Electrical engineering, computer science including programming, language and communication skills. More than anything else, I have learnt to appreciate and get reminded of all the trials one must go through to learn such little things which, after learning, invariably appear trivial to us. Here's a list of things which appear deceptively simple, but are learned through tremendous hard work and even luck. For some strange reason, they surely don't end up in the kitty of a large majority of the population, unfortunately.

Logic. The ability to use existing knowledge to deduce or induce further inferences. To understand about theorems and proofs, about possibilities and probabilities, in a day-to-day sort of way. 
Communication. The ability to express a thought as it exists in one's mind. To listen and interpret what other's are conveying as they mean to.
Concentration. The fundamental experience of being in a flow while thinking of or doing one and only one thing. And to enjoy it. It brings out the real power from inside. It helps you to not get tired even in an intensely effortful activity. It makes you want to have a repeat experience thus enabling the habit of hard work to set in, increasing efficiency and effectiveness in the long run. 
Alertness. To be aware of the world around. For example, It helps manoeuvring safely in a complex traffic condition and making timely decisions in crisis situations. This also gives us the ability to enjoy little experiences and find value in moments which would be a drudgery for most.
Abstraction. The ability to think of thoughts, ideas, dreams, patterns, as real entities. It allows you to do things which are distinct from the knee-jerk thing that any beast would do, that of taking the path of least intellectual resistance. It allows you to set up businesses. It allows you to try and serve the society. It enables to you model and design complex systems. It gives you the courage to cut open a body and fix an ailing heart. It allows you to compose concertos and visualise impressionistic or surrealistic paintings and write novels. It enables you to thing big. It prepares you to be curious and experimentative.
Open-mindedness. The ability to accept, appreciate and be comfortable with the different ways people and situations are. This enables us to take genuine interest in and engage with people apparently different from us and profit from the numerous good things they bring with them in a win-win way.
Self-awareness. The ability to turn one's eyes on oneself, to examine, question, study oneself. The ability to gather the instruments -- scientific, philosophical, sociological, anthropological, spiritual -- that allow such a study to be done. This gradually grows the comfort with the good and bad things about oneself, and find virtue and meaning in life in presence of failures, losses, weaknesses and vices.

I don't mean to say that I am an expert in all the above. But surely I have got to the point that I know that they exist and they are very powerful. They affect the way you live your life and influence others'. I also understand that it's probably vain for me or anybody to try and assess the value of one's learning through the knowledge of science, arts, or engineering. These, with all their success, are too specialised to matter in the general context of an individual's life. There are rather these other things which are listed above, whose value isn't restricted to specific contexts and settings, but are generally applicable in all walks of life, and any setting.

Painting and Life




Some reasons why paintings look similar to life.

  • If you want to be happy with drawing, draw for yourself. Then share your happiness with others.
  • You may want to sell it, but it is worth nothing unless you feel it is worthwhile.
  • Each brush stroke brings the painting closer to what it would become, and only the artist can guess.
  • Little mistakes are all forgotten. Unless you see the big picture, there's no hope. It's too complex if you only look at the details.
  • A copy is just a copy, not a painting. A painting is a painting only if it has its own story to tell.
  • A part of the beauty lies in the eyes of the beholder.

A Day Stolen from Childhood

(Welcome the 250th post on this blog!)



Yesterday was Vigyan's first day at Christ Academy as an LKG student. We were there in the first few moments. The assembly. The prayer. The national anthem. The news, the thought-for-the-day, the saavdhan-vishraam. The school parade-band. While Vigyan stood awestruck and overwhelmed, Shilpi and I stood with millions of memories of our childhood flooding in. The happiness and nostalgia, too intense to be expressed in words, found its outlet through a big lump in the throat and a moment of dampness in my eyes. 

Who says the childhood, gone once, never comes back? We live it day by day, through our child.

IPL's Sexism

With reference to the article, India’s premier sexist league (May 16, 2013, The Hindu), I have the following observations:

Old-timer stalwarts, good at cricket and talking about it, are made to pose
Models, good at posing, are made to comment on cricket

Firstly, use of women as cheerleaders or sexily attired woman hosts in cricket isn't very much in the traditional spirit of cricket. These are the real acts which have associated objectification of women via cricket.

Secondly, the way cricket commentary has evolved in the recent years has put some otherwise remarkable people in very awkward situations. Remember Mandira Bedi, a fairly talented actress and model? She was the first in India brought in to give a make-over (not necessarily much-needed) to Indian Cricket commentary. I am sure she would make a very lovely host to a reality show. But when she was made to sit alongside the likes of Ravi Shastri and Harsha Bhogle, it is hard to expect her to match them in her insights about cricket. No wonder, she was found goofing up rather often. Now, matters have proceeded further in the direction of glamourisation of cricket commentary and analysis. Now, the cricket studio is very little about insightful analysis and mostly about acting like socialites, something models would do much better than cricketers. No wonder, it's the cricket experts' turn to goof up. First, the seniors are made to adapt to this very foreign style of talking and conducting themselves, thereby forcing them to commit errors. Then, they are ridiculed or criticised in public. Not fair!


Finally, I agree that the way IPL is being clothed up, it shows a demeaning attitude towards women. Talking of rapes and harrassment in the same breath is a bit of a stretch, if not irrelevant. But our seniors should be left out of this debate, if required, by not subjecting them to the completely changed scenes in the IPL studio.

The Endpoint of Electronics City

People think, probably rightly, that Electronics City is a special economic zone(SEZ) or something. Then, how come we stay in Electronics City? They keep asking. After all, an SEZ isn't supposed to have residential complexes in it, isn't it? I don't know the answer. I write Electronics City in my residential address. I have probably expected a couple of mails or parcels at my residential address so far. They have all reached me. And my guests have never lost their way too. So, colloquially, our residence is indeed within the Electronics City limits. But formally, probably not.

Where is the formal boundary of Electronics City? I don't know who could give me the precise answer. But a bit of looking around gives me a hint. I guess, the answer is: Wipro Gate.

I clicked a few photographs this afternoon while on my way to office after lunch. The sudden contrast in the scenery seems to be a reliable enough indicator. I am quoting some of the photos in this post. For a few more, you are welcome to visit the album.

How To Avoid Gross Generalisations

Here's a list of the kind of generalisations I am talking about:


  • Muslims are terrorists.
  • Men are sex-maniacs.
  • Women are poor in mathematics.
  • Wearing short dresses increases your risk of being raped.
  • Intellectuals are socially impaired.
We live with many such generalisations, most of them are true bullshit. But we often have to tolerate them. People all around us throw at us such nonsense everyday. Opposing each and everyone of them would throw you out from fashionable gatherings in no time. So, there's often no other way but to keep quiet.

But we must protect ourselves at all costs from one thing: making such generalisations ourselves.

Here's one simple trick.

Almost all these generalisations are of the form: "G is/are C." where G is a group of people, and C is a characteristic.

Now, before you admit to any generalisation of the above form, check also if the following are true:
  1. not G is C.
  2. G is not C.
  3. not G is not C.
The first, not G is C, means that people not belonging to the group G have the characteristic C. If so, the generalisation probably doesn't hold.

The second, G is not C, means that there are people belonging to the group G who don't have the characteristic C. If so, this too weakens the case for your generalisation.

The third and the last one, not G is not C, means that people not belonging to the group G are found not to have the characteristic C.

Only after you have examined your hypothesis from all the above angles is there is any significant probability that the hypothesis is well-founded. Otherwise, it's merely a thought, a stereotyping, a gross generalisation.

You may find the above little trick useful to work your way through any unpleasant argument that you may unfortunately get into with someone making an intolerable generalisation. But, without fail, make sure you put it to good use against getting trapped yourself making any such generalisation.

Fall of The Hero




Yesterday, when our housemaid was about to leave after finishing her work, her umbrella broke. I tried to see if I could fix it. I fiddled around with the rods, and buttons and springs and the linkages and the unwieldy cloth on top for a while. Eventually, I found the matter to be more complex than I could handle, and meekly surrendered.

All this action had an audience in my son Vigyan who watched with rapt attention, repeatedly coming dangerously close to all the poky things coming out the broken umbrella and had to be shooed away. He was watching his dad try fixing an umbrella!

Eventually, I handed over the separate pieces to our housemaid begging her pardon and asking her to take them to an umbrella-maker. She left. And we were about get back to our own respective chores and forget all about the little incident when Vigyan did something that made sure that this little incident would stay forever etched in my mind.

I felt a pull on my shirt, and I saw an almost teary-eyed Vigyan looking up at me. I took him in my arms when he asked: 'Baba! I know you are very strong? Then why couldn't you fix the umbrella?'

It was just a matter of time. It had to happen. This painful experience is the destiny of every son and daughter to realise that his father is not the strongest person in the world but an ordinary mortal. That the father too fails and falters like everyone else.

While I hailed him with kisses and hugs, I told him that even strong people can't do everything. My own eyes welled up to imagine how many times Vigyan will be subjected to the excruciating experience of witnessing his father's weaknesses!

We on Our Roads

I just went through this article, and I couldn't agree more.

The article points towards some research findings that being rich robs you of your empathetic nature.

It's really true according to me. Recently, I was discussing on a related matter with a friend of mine about the behaviour of people residing in posh apartment complexes. Particularly on how they find it perfectly justified for them to waste resources like water, electricity and food, just because they have paid for it. It seems when my friend suggested in one of the casual conversations to one of his acquaintances that we should be considerate on such matters, the other person there said, 'that's not life!'


Can anything be any more degrading than to believe that being considerate is no more an option for humans?!

Before this article gets dismissed as another social bitching piece, I want to bring to your notice another issue: about how we look at our right to use public infrastructure, particularly roads. We have no order on our roads. They are polluted and dangerous. But above all, our roads are excessively crowded. The road cries out in pain when yet another car gets added to this mayhem, even if that car is yours or mine! Cars are the main reason why our roads are so dangerous, not the other vehicles like autos, 2-wheelers and buses, however much we might like to blame them for the chaos, and to take pride in our awareness of the mannerisms of more orderly roads of other countries. And that's simply because cars are so inefficient in terms of everything: fuel, space, maneuverability. Once we give up for good all the other more efficient and compassionate modes of travel for a car, what's this we are trying to convey by criticising those other people who scramble around for that little space we have left them with on the roads?

Please consider using public transport sometimes. Please use a 2-wheeler instead of a car if you can. Please take out your rusty bicycle for little personal excursions in and around your locality. It's good for your health. It doesn't pollute. It glides smoothly and noiselessly on the roads and quickly gets you to your destination. It burns up that fat in your body which you struggle to burn on the treadmill in your air-conditioned gym.
I have seen people going further than not accepting the nobility in minimalism. By calling such acts vanity in the disguise of simplicity.

Start by taking the first step: by accepting that it is good to be considerate and compassionate on the road and elsewhere. Please have the courage to accept that the people who have chosen not to crowd and pollute have done an act of integrity. They deserve your respect and admiration; not ignorance and definitely not scorn. And accept that if you aren't able to do the same thing, it's not a happy choice, but has got to do with some limitation on your part: distance, lack of fitness, or -- as is most probably the case  -- mere laziness, or even worse, vanity.


Please stop giving the lame excuses about pollution. Adding to litter just because there's already a heap of it lying there isn't justified. Same applies to corruption. Why doesn't that apply to pollution and crowding? Just because you hate inhaling polluted air, you decide to contribute to this state by pumping in loads of CO everyday by preferring a car to a two-wheeler or public transport? Isn't that selfish and inconsiderate?

I have been driving a 2-wheeler for 25 years (a dozen of them in Bangalore). I have been riding a bicycle for even longer (a dozen of them in Bangalore again). I can't say anything about tomorrow. But I am alive today. I haven't been knocked down so far by any rogue driver. And I can vouch for the fact that I am less unhealthy than I have always been in large part due to my on and off (progressively more on than off) bicycling. I believe that, despite the dangerous conditions of our roads (which I don't fully deny), a lot of your own safety depends on you. Being a bit cautious, and not depending on the same from others, does the trick. It may slow you down, frustrate you a bit. But that's a lot better than risking your life or not cycling at all.

I am sorry to see that while many of the people of my age group are finding their way back to healthier and fitter lifestyles, younger people find it their prerogative to desire cars as a necessary luxury as soon as possible to mark the fact that they are doing well in their lives. What a pity! Isn't it the same mentality as that of thinking that you have every right to consume as much resources as you wish as long as you are paying for it? Wake up guys! Learn that the need to show off one's achievements is already bad enough. To think it one's entitlement to potentially disastrous modes of vanity is nothing less than criminal.

The happiness of doing well in life comes with a bunch of responsibilities. Achievement devoid of commensurate awareness, knowledge, thinking, compassion and wisdom is not worth a farthing to anything including yourself. Simply because any such happiness simply can't exist. Consider not searching happiness by inflating your ego endlessly. There are other more direct and less disastrous ways to seek happiness. And they don't eventually end in a naught.

Well, before I turn too acidic and digress, let me conclude with a wish list:

  1. That we all had behaved better on our roads. 
  2. That we had been more respectful to the people who built it, and to those who laid down rules and directives for good driving.
  3. That we followed rules without having to be watched over all the time.
  4. That we showed some respect to our fellow users of the road by keeping distance, by not overtaking too much, by not driving non-linearly, by not honking too much. 
  5. And finally, that we had respected the fact that the space on the road and breathable air in our atmosphere are both exhaustible resources, and had taken to less polluting and less crowding modes of transport wherever possible.

Poem for My Beloved Son

(Poem written by my friend Sudhanshu for my son Vigyan) - Thanks Sudhanshu! There can't be a better gift than a creatively exposed thought or feeling. :)

                   विज्ञान के लिए 


एक शिल्पी के सृजन से ज्ञान की ज्योति जली
ज्ञान की ज्योति में थी जीत की अद्भुद चमक,

                       ज्योति है वो ज्ञान की, शिल्प के अभिमान की 
                       जीत के अनुराग की, जीवन के अनुसन्धान की, 

पर ज्ञान वो विशेष है, सहस का जिसमे निवेश है, 
सुजीत शिल्पी के लिए, वो प्रेम का सन्देश है, 

                         ईश्वर करे वो ज्योति फिर बन जाये अग्नि यज्ञ की,
                         आहुति जिसमे सत्य की, और अर्चना हो कर्म की,

फल मिलेगा यज्ञ का, रूप लेकर ज्ञान का,
ज्ञान के संधान से, होगा जनम विज्ञान का

Is Time Travel Logically Possible?


(This is an extended version of the essay for an online introductory course on philosophy I took in Coursera.)
Introduction
In H. G. WellsThe Time Machine, the protagonist travels both backward and forward in time. The Doraemon animation series which was created in Japan in the 60s features a robotic cat who travels 2 centuries backward. In Hollywood, we have Terminator series which is predominantly based on the theme of travel. A web-search on 'mythology' and 'time travel' would bring up many resources. But human's fascination with time-travel is not new. Einstein's special theory of relativity (1905) and then General theory (1915) gave a hint that time is not a physical absolute that keeps all universe chained to one single point which moves at its own personally chosen pace. Different objects experience different personal times depending on how close their relative speeds are to the speed of light. It's over a 100 years since then. Design of time machine hasn't been achieved yet. That prompts us look at the phenomenon of time-travel with some more scepticism; to investigate what would logically entail when the external and personal times of an object start diverging.
Here I present my thoughts on time travel. In this essay, I present three arguments: Unique existence, impossibility of passive existence and causal loops. My analysis makes me believe that time travel may not be a logically well-founded notion, at least not in the form we popularly perceive it in.

The Issue of Unique Existence

This argument rests on an assumption that, given any point and time in all space -- the (x, y, z, t) co-ordinates -- there can be only one particle occupying it. Suppose I (means, the collection of all particles in me) am occupying a particular space at a given point in time. What happens if an object or person travelling through time pops out this very moment -- apparently from nowhere -- to occupy the same space that I occupy. What would happen to the particles in me? Would they be displayed here and there? Would they just disappear giving place to the newly arrived object? At any rate, two particles occupying the same coordinates in the space is incomprehensible.

Impossibility of Passive Existence

The phenomenon of objects popping out of thin air has yet another issue. Each such event is bound to create counterfactual changes. Even if an object pops out at a point previously occupied by nothing else (i.e. vacuum), it's sure to change the course of history of the universe. If it's a charged particle, it will set an electric field around itself. A radiating object will change the illumination of the place. If not anything else, the very fact of an object having a mass immediately causes it to interact with all other particles of the universe through the force of gravity. The fact of something's existence is fundamentally determined by its ability to interact with the universe surrounding it in someway. Even a passive spectator of events around it must be stimulated by physical stimuli (e.g. light, sound waves etc.) to sense them. Absorbtion of physical signals results in changes in the surrounding that wouldn't have happened if the signals hadn't been absorbed. In other words, an absolutely passive existence sounds like a vacuous idea. May be, invoking Descartes' idea of substance dualism may succeed in modelling such a 'ghost' existence. But, in my mind, I am unable to do so.

Causal Loops

The most serious difficulty in the notion of time-travel, according to me, comes from the notion of causality. If we write out all the events in the universe, and for every pair of events A and B, we draw an arrow from A and B if A directly causes B This exercise (of drawing arrows between events) would give us a directed acyclic graph (DAG) of causality. As per this idea, all events in the history of the universe can be tracked back to a set of events, which in turn, aren't caused by any other event. There can exist no cycles of causality in this graph. Put another way, no event can directly or indirectly cause itself.
However, time travel can create cycles in this causality graph. Several examples are present in the Terminator series of movies. For example, a soldier named Reese is sent back in time by John himself from the Terminator. John is born out of the love between Reese and his mother Sarah. Does this mean that John caused his own existence? In fact, it would have been possible for John to father himself, had the storyteller decided to tighten the loop of causality a bit further! Even more interesting is the advent of the Skynet -- the AI network which wages a war on humans. Skynet develops out of the remains of the first Terminator, the one which had travelled to 1984 from 2029 to assassinate Sarah. And its Skynet which creates Terminator. The question is: wherefrom comes the idea Skynet or Terminator. They seem to have begotten each other! The trouble here is more serious than that a machine invents a machine. We may imagine, at least in theory, that AI machines sophisticated enough may even invent other machines. But the acyclicity of causality is an even more important requirement in the case of ideas and thoughts than in the case of physical events like birth of people.

Conclusion

We have presented three arguments which speak against the logical possibility of time travel. The first objects to time travel based on the incomprehensibility of two particles occupying the same co-ordinates in space at any given instance of time. The second rests on the notion that existence of a physical object can't be passive in true sense; it must interact with the outside world. And therefore, it must have a role in the course of history. The third objection rests on the assumption that causation is acyclic: Time travel makes it possible for events to cause themselves.
There are other difficulties which are physical. For instance, how would time travel as we understand it, fit in with laws of conservation of mass and energy?
It also appears to me that the objections raised above, more than proving a fundamental impossibility of time-travel, brings forth a certain incomprehensibility of the reality that would result from it. To prevent time-travel from creating an anomalous universe, one must imagine a concept of time travel very different from the one popularly held.

The Hidden Horse

Indeed, why does a painting or sketch of something often look better than the thing itself?

I don't know the precise answer. But I am reminded of an anecdote an old friend of mine had once shared with me.

In one of those North European countries (I don't remember which), there happens to be a community of artisans specialised in making wooden toys. My friend, one day during one of his trips to the place, stood watching a person making a wooden horse with fascinating precision and speed, almost hard to believe. After a while, my friend couldn't contain himself and asked the craftsman how he managed to do such a hard thing (building toy horses) with such ease. The good natured man smiled and said in his accented and broken English: "Not hard at all. Not hard at all." Then picking up a block of wood, he said: "Here's wood. You just have to remove what is not horse. And there! You have your horse!"

...and this story seems to be a block of wood hidden in which seems to lie the horse -- the answer to the big question: 'Why does a painting look better than a scenery?'

In every block of wood that passes before our eyes, there's hidden a horse. An artist, in some way or another, just takes that horse out and presents it to you. In every scene that passes before us, there's a painting hidden. An artist just takes that painting out for us. By highlighting what's interesting. Abstracting away the rest. Often, he highlights what could be interesting.
