Moral behaviour in animals


Frans de waal on moral behaviour in animals.



The argument being that animals also display cooperative behaviour and empathy.

Irrespective of this argument, there are problems with the talk. Most of the animals have been trained to perform those behaviours.

Cooperation

Chimps and bonobos who display reconciliation behaviour - Isn't reconciliatory behaviour mostly linked to dominance? Yes. But how different is that to humans, you say? Maybe not very different. But our culture and cognition means we need to view reconciliation differently. In any case, dominance should have been mentioned in the talk. And if not, De Waal should have at least mentioned that cooperation in chimps differs from cooperation in humans.

Chimps cooperating to pull a reward - The partner could be motivated by fear. I need more information.

Elephants cooperating to pull a reward - Again, the elephants are trained to use the apparatus. This does not reflect instinctive cooperative behaviour, rather that one elephant is smart enough to learn that he doesn't need to do any work on his part to get a reward. I can just imagine that elephant doing that trial over and over again till he realises he will still get a reward if he just places his foot on the rope. And the fact that the partner does not get any reward also needs to be remembered. How long would the partner keep this up if it wasn't being instructed to by a mahout? This isn't really cooperation as we know it.

Empathy

Chimps and contagious yawning - Firstly, can we really connect yawning with empathy? If so, what part does dominance and gender play in this experiment?

Children empathising with adults - You can't compare children and adults because of dominance again. Would children show similar empathy towards other children?

Prosocial choices by chimps - Again, no control for dominance and gender? A chimp might be prosocial because of dominance, not empathy. Yes, this could be considered one interpretation of what constitutes empathy to begin with, but it must be stressed that this is very different from human empathy, where we put ourselves in someone's else's place and see things from their perspective. Do animals do this? Or is their empathy more basic, if they have any at all?

Capuchins reject unequal pay - This is more about a sense of fairness. Not really empathy.

I have no doubt that many animals have a sense of empathy, but their empathy tends to differ from that of humans. Empathy, like many other things, is a continuum & we seem to be on a different part of this continuum than animals.

If we could devise a series of experiments to show that this complex empathy of ours is really no more than a cover for a more basic reaction with adaptationary value, then I'm wrong, but this hasn't been indicated yet.

Breaking Bio


In case you guys haven't heard about it yet, there's this cool biology podcast series that's happening at http://breakingbio.com

Here are some useful PhD tips I've gleaned off the first few episodes:

1. Be prepared to explain your work to other people. Prepare your elevator speech.
2. Some people have parental support and inspiration. It's tougher for those who don't.
3. It's tough to find jobs after a Phd. You need to relate your degree to stuff that's relevant.
4. you need to find a balance between your work and social media.
5. Online journals can be better than real life meetings and clubs.
6. sometimes, Masters degrees are essential stepping stones to a PhD. It might not be a good idea to phase them out.
7. Don't do a PhD unless you really like the science and have funding.

The Religion-Violence Correlation


Well, Mumbai had another riot a few weeks ago.


A group of Muslims came to Azad Maidan for a demonstration, some carried weapons and the situation soon grew out of hand. The demonstrators went on a rampage, destroying property and attacking people, before being brought under control a few hours later.


I don't want to go into specifics but look at this event in the more general terms of religion and violence as a whole.


In the aftermath of the riot, fingers were pointed and names were called. I'm not talking about political oneupmanship and bureaucracy. I'm taking about you and me. I'm talking about what normal people talk about in homes, on the streets and online.


People antagonistic to Islam and Muslims felt this was yet another sign of how bad Muslims are, or how much of a curse Islam is.

People who don't like religion saw in this riot another indication of why religion is evil, and played up the harm that religion does to society.
Moderate Muslims apologized on behalf of the rioters and urged justice.
Apologetic Muslims urged people to think about the reasons why people would resort to violence to begin with. 

Which brings up so many points.

Who takes the blame for this?


Firstly, why do we even need to assign blame? Well, because we choose to live in a society governed by elected representatives who are supposed to ensure that we lead a peaceful non-stressful existence. That's what we pay them do do.


Did they perform? No. The police did an admirable job in not letting the riot escalate, and in ensuring law and order returned asap. This quick response is something they need to be commended for. However, it does not excuse them from the fact that they failed to preempt the riot to begin with, and those in charge need to be punished for this.


OK, so with the obvious blame over, can we blame Islam?


Yes, the rioters were Muslims, yes the riot was seeped in an undercurrent of Islam, and yes, if they weren't Muslims, they wouldn't be rioting. Does that mean we blame Islam? 


No, we don't, because Islam is a religion, not a person. It is merely a collection of ideas that people subscribe to. That the principles behind Islam are both ridiculous and irrelevant in today's context is beside the point. The point is they're just principles, which people are free to ignore.


So do we blame the Muslims, people who choose to follow Islam? 

Well, yes and no. 


We don't blame all Muslims, but we blame those who choose to interpret a religion or a belief system in a manner that leads to violence, because their form of expressing this interpretation goes against our laws. 

However, we can't generalize or extrapolate one set of rioters to all Muslims. Only a fool would do this. Most Muslims were as scared as other Mumbaikars when the riot broke out. Only a moron would look at a Muslim riot and go "we must rid this city of all Muslims". 

OK, but why call the rioters Muslims? Why associate them with Islam? They're just criminals, aren't they? Why associate them with any religion?

Because Islam is what the rioters themselves associate with, and it's stupid for us to ignore that, because this sort of information is useful in observing and predicting the ways in which a society moves and how to best control it in future.

Just because the majority of Muslims are wonderful non-violent people doesn't give us the right to purposely disassociate the rioters from Islam. It is entirely possible for two sub groups of people within the same group to interpret a belief system in two different ways. Both the majority and minority sub groups can scream hoarse about who's a true Muslim and who isn't, but they can't disassociate either subgroup from Islam itself, nor can anyone else.

Speaking of anyone else, the one thing that irritates me as much as anti-Muslim fundamentalists are the clueless liberal elite who think that religious rioters are mindless ignorant beasts with no religion. This is just stupidity and I don't know what kind of ignorant guilt-induced political correctness gone wrong, instigates this. 

Sure, all rioters irrespective of ideology tend to act like mindless ignorant beasts when rioting, but their riot has a basis to begin with, and in this case it's their religion. 

This doesn't mean we generalize the riot to draw ridiculous conclusions about Muslims. It just means the riot has a religious basis and we use this information as usefully as we possibly can. Period.

But wouldn't it be easier to just crackdown on Islam and all Muslims? 

This is illogical. You don't punish the group for the individual.

True, fewer Muslims would technically mean a lower chance of riots, but that's a ridiculous generalisation. By application, if the workers in a Maruti factory in a small town decide to riot, do we then get rid of all Maruti workers, or all Maruti factories, to ensure no further riots occur? 

At some point of time in the evolution of a civilization, any group within that civilization is liable to riot if enough members within the group resort to the same kind of violent herd mentality. 


To ban Islam is to ban Christianity is to ban Hinduism is to ban Buddhism is to ban atheism. They're all guilty because they're all groups, and all groups encourage herdthink. 

That one group is currently more violent than the others doesn't exonerate the others. It merely demonstrates that the difference in violence wrought by these groups at any particular time is one of extent rather than principle.

Is this a sign that religion in general is evil and dangerous?

Dangerous, yes. Evil, no. All religions being collections of principles, the only thing that matters to society is how stupidly people interpret these principles.

We can counter this by guarding against groupism in general, by making sure people are aware of the dangers of religion, of any belief system, of any group, of any fundamentalism.

So in summary, do we associate religion with violence?

Yes, we can, wherever we can, as long as it's not a correlation brought about by sinister or ignorant intentions with personal agendas in mind that don't really help anyone.

The Church of Atheism


I've been observing an increasingly disturbing trend lately. Atheists are forming organised groups. They're showing signs of fundamentalism - acting privileged, entitled, superior, rude and harassing religious people online.

To Begin With

I've written before on the futility of belief, and why non-belief is logical. However, these are my personal views, and I hold that imposing these views on anyone else in wrong. Also, it would be wrong on my part to expect everyone else to adhere to my personal views. Just because I see a way of life to be logical or rational doesn't mean everyone has to hold to that view. It is fine for people be irrational, even purposely so, as long as they're not hurting anyone else.


Take religion for example. Religion is irrational, yet it's OK for people to be religious. It's their personal choice. Should religion be encouraged? No more than any other form of irrationality is. Should religion be protected? Of course not. Ordinarily, a state has no part to play in the religions or personal belief systems of it's citizens.

Which is why I'm growing uneasy over this new type of militant atheism, an atheism that people subscribe to like an actionable belief system, rather than merely a philosophy or a personal set of viewpoints. An atheism that has loyal followers who are beginning to resemble religious fundamentalists, ready to defend their atheist leaders and core principles, ever ready to preach to those disinclined to listen. 


We need to guard against this new type of militant atheism.

Atheism Does Not Need Fundamentalism to Work 

I think religion will eventually die out when people see there's no point in taking things on faith, when they realise that the concept of belief itself is pointless. This will happen slowly over time. The number of people who associate with non-belief increases each year. 

Arguments that rationally undermine the concept of belief have been around for ages. These arguments form the foundation of atheism and do not need patron saints like Christopher Hitchens or Richard Dawkins, or their lapdogs to defend or promote them. 

Militant Atheism is Really Harmful to the Cause

As a rationalist, I have to say that men like Christopher Hitchens and Richard Dawkins actually do more harm to rational thought, simply because they rarely indulge/d in any. 

Men like these may occasionally present their ideas logically, but spend more time asserting their superiority over religious people, insulting them, being rude, acting superior and generally just being assholes, that they alienate not just religious people, but the fence sitters as well.

Hitchens in particular was adept at using rhetoric and hyperbole, side-stepping any attempt at debate with humour that reinforced his own one-dimensional points. That his original arguments made sense by themselves is beside the point. The point is that he used the same arguments in contexts that rendered them irrelevant. 

For example, in this debate with Shashi Tharoor on freedom of speech, Hitchens shuns any attempt at engaging in actual intelligent debate. He seems incapable of looking at the world and questioning it in any way that doesn't allow him to spurt his crowd/ratings-friendly one-liners at every opportunity he gets.

Now, as a result of this, two things happen.

One, you give your detractors more ammunition to work with. You are going to be seen as someone who changes the subject and avoids debate, preferring narrow mindedness instead. 

Two, you alienate all those people who want to be on your side, who genuinely care about intelligent debate and an exchange of ideas, and make a mockery of their time.

Groupism is Bad

A true rationalist is interested in debate and an exchange of ideas. That's not what I'm seeing today. I'm seeing people who under the guise of enlightenment, take great pleasure in forming a clique and shoving their non-belief down religious people's throats. 

This is dangerous because, as we've seen in history, any type of groupism has potential to go very wrong. The moment like-minded people get organised around an idea, the potential for disaster is present, especially when that idea revolves around persecution of supposedly inferior beings. 

This is the same kind of groupism that we've seen in religious groups, and we all know the kind of violence it can lead to. In fact, groupism isn't confined to religion. How many millions of people did atheist governments in China and the former USSR kill?

This sort of 'lynch mob' mentality is exactly what happens when you have people eager to belong, to be part of a group, to be part of a movement, something greater to themselves, so that they have meaning in their lives. You see this kind of tribe mentality in all sorts of groups.

On Intelligent Atheism

Is it surprising then that it manifests itself in atheism too? To me it is, because I never imagined any kind of rationalist movement as a kind of cult, which is what it has turned into. 

Rationalism is all about being an open minded skeptic, friendly, ready to engage, open to new ideas, discussion and debate. And let's not forget our humaneness too. Despite all our rationality, we must respect other human beings for their views, whatever they are, even when they decide to be irrational. Their reasons are their own.

I don't see this kind of respect for other human beings in new atheism. If you're not constantly spewing hatred for religion, you're the enemy. If you don't agree with Dawkins or Hitchens, you're the enemy. Atheist fundamentalists cannot grasp that you can be a staunch atheist and still disagree with these so called 'experts'. 

This kind of 'seeing the world in black and white' mentality while ignoring the grey areas is exactly what leads to groupism and possible violence, and is antithetical to the healthy debate that rational thought encourages.

No Excuses

The main excuse of atheist fundamentalists is that their harshness is merely a response to injustices wrought on the world by religion. To which I say "Phooey". 

Granted, the influence of religion is far reaching, and much needs to be done to reverse this. But that does not mean you shove your ideas down people's throats. That doesn't make you any better than the people you're trying to put down. 

And it doesn't accomplish anything. If anything, it makes it worse. Most people dislike non-belief being forced on them as much as they dislike religion being forced upon them.

So in summary

Believe what you like, and keep it to yourself. 
Engage in healthy debate if you feel like it and find the right people to talk to. 
Hear people out and seriously consider what they're saying.
Think and reason logically. 
Be objective. 
Fight for your rights and the rights of others. 
Fight to halt and reverse the dangerous influences of religion.
Support the freedom of religious expression up till the point where it infringes on your rights.
It's fine to hold up a mirror to the absurdity of religion or any irrational thought process to demonstrate how absurd it is, especially when provoked. 
Don't be rude.
Don't end up like one of them.
Keep your individuality. The moment you join a group, you sacrifice a piece of your individuality for a group identity. Be aware of this.

Inventiveness


Here's an article about a guy who took 11 hours to make 300 apples power a LED lamp, and then took a 4 hour exposure of his experiment on film.

http://blogs.discovermagazine.com/visualscience/2012/07/24/how-many-apples-does-it-take-to-power-a-lamp-about-300/

I love stories about inventiveness. Inventive people do crazy fun stuff, like build Rube Goldberg machines, which I love.

http://coolmaterial.com/roundup/rube-goldberg-machines/

I am always dismayed by people who are dismissive of inventive people. Inventive people are dedicated to their work, and their experiments move the world forward.

If you think about it, all of the things we use on a day to day basis came into being when someone had an idea that revolved around creating something, and decided to experiment with something else, or fiddle around with some contraptions with a view to improving life on this planet.

All the products we use today were invented, they arose out of a series of continuously improving inventions over time. Our electricity, planes, trains, cars, ships, buses, microwaves, ACs, cameras and computer systems were all developed by groups of people improving each other's work over time.

None of these inventors were mere consumers of products that existed in their lifetimes. If that's all they were, we wouldn't have all the stuff we do today. If Thomas Edison or the Wright brothers were merely content with what they had to begin with, with what other people had made for them, our world wouldn't have developed in quite the same way it did.

It was because these special people acted on their impulses, working with and developing the technologies they had, that they came up with new inventions that were in turn improved upon.

And those improvements continue today. Inventive people are continuously toiling away at something they believe in, creating products that other people use, even if that's not always apparent, like with fruit powered lamps.

Here's a video describing the work of Theo Jansen, who creates kinetic sculptures.

http://www.youtube.com/watch?v=5N0IonPOy-I&feature=related

I've never been particularly inventive myself, but I appreciate the importance of inventiveness, and I think other people should too. Of course, I don't think everyone should be inventive. Civilizations thrive on diverse skill sets. If everyone was a geek, the government wouldn't have anyone to defend the country. In fact, in a case like that, there might not even be a government. Now what would THAT do to a civilization?

Book Review - Chicken Soup for the Indian Couple's Soul



So I recently read this book called Chicken Soup for the Indian Couple's Soul.


It's one of these feel good inspirational books for people who need them. As the book by-line reads - inspirational stories about love and relationships.


Firstly, this book is huge. I wasn't able to get through it in my usual time, in spite of the fact that I usually skim through books comprising short stories. I suppose this had something to do with the subject matter. I'm not much for literature aimed at inspiring, and this is the first Chicken Soup book I've read, so I wasn't even sure what to expect.


Right, so the book contains around 100 short stories (by a staggering 75+ contributing writers) split up into a bunch of interesting relationship related categories.


The book begins on a bittersweet note with 'The Odd Couple' by Tanya Mendonsa, and continues on with other stories dealing with people who met online or met each other through other means, people who seemed like they weren't right for each other, people who lost and found each other again, etc.


The second set of stories, on starting a family, is somewhat less romantic and covers a diverse range of situations in which people have found themselves in, from struggling with a new born and the consequences that inevitably follow, to not being able to have a child.


The section on love and support is less somber, and also includes a couple of stories I really like. One is travel related, and I wish it were longer. Written by Bunny Gupta, it tells of a Nepali couple and their setting up a life together.


The other, a poem by Roma Kapadia about invisible walls we build, is probably one of the most beautiful and relevant poems I've ever read.


A matter of perspective has some weird stories that don't really seem like they're going anywhere as far as a common theme is concerned, but they're decent reading anyhow even if their classification is haphazard.


The next section, In Sickness and in Health, is predictable, dealing with people sticking with each other even though one party is sick.


This theme is carried forward in Overcoming Obstacles, another set of assorted short stories, a good one being 'The Fragrance of Rice' by Nonda Chatterjee.


Coping with Death sounds like a collection of macabre stories, but a lot of them have cheerful endings, ending with new hope. Ba Bapujee and A Touch of Love are especially good examples.


The last section The Fire Never Dies is an assortment of stories that showcase stories of relationships over time, some sad, some happy. A mixed bag, like life itself.


Given the range of personalities and situations, this is the kind of book that offers enough situations or emotional settings that everyone can identify with at some point. This, and the simple prose, make it a good read for people looking for light inspirational reading.

13 Trekking Tips You Might Not Have Heard Elsewhere



1. Trek at your own pace. It's not a race. You're not here to compete with the rest of the group.


2. Do not leave the group and wander off alone. If you find you're lagging behind, try to pair up with a buddy.


3. Trek with meat eaters. They carry better food.


4. Trek with pros. They know what they're doing.


5. Never be the first person in a line of trekkers. You will also be the first person to walk into spider webs.


6. Always trek behind girls. In case of backdrafts, they smell better.


7. Never wear flat soled shoes.


8. Always wear a hat.


9. While walking up or down a steep curving bend, it's less effort to walk around the outer edge of the bend, but also longer. It's a trade-off.


10. While walking down a slippery slope, either take long confident strides, or slow measured steps. In the former, you might fall down less, but fall hard. In the latter, you might fall down more often, but lighter. It's a trade-off.


11. While trekking, wear anti-perspirant, not deodorant.


12. It's preferable to trek with girls. Girls talk less while trekking. Guys always have irritating trekking stories. They can't shut up.


13. If you're not a smoker, never trek with smokers.
