The Post-Modern Dialectics of Belief

I have been musing a little bit about belief, especially after a couple of outraged comments on the previous post about the absurdity of the moon-sighting charade that occurs ever few months. We get similar comments every time we post something about the irrationality that seems to pervade the thinking of literalist followers of religion. There really is no way to argue against belief. If someone actually believes with all their heart that white is actually black or that the placement of Venus relative to Mars will affect your chances of finding true love, how do you argue against it? A belief, by definition, resists interrogation. A good part of religion involves blind trust - that a beneficient god (or gods) exists, that everything that occurs has a hidden, deeper meaning, that there is a goal to strive towards, and that the path to that goal as defined by the religion is the best route to achieve it.

I should point out that I have no issues with people's personal spiritual beliefs (it's their own space after all and human history shows us that everyone requires some sort of belief system to survive) and I do think that on the whole all major religions (all the ones I know of in any case) share a desire to create a better, more just society (even if their followers' interpretations can tend to lead one to conclude differently). The desire to believe in a power greater than ourselves, to bring meaning to apparent anarchic chaos, is deeply ingrained in the human psyche, and I am not one of those whose mission in life is to go around attacking religion in toto.

But problems do arise when personal belief systems are either imposed on other people who wish to have a different belief system or, as in this case, when belief is substituted for an argument even in the face of tangible evidence to the contrary. If someone really believes that God intended for us to order our lives only by looking upon the moon with a naked eye (as the maulvis of Pakistan seem to believe), there is little that logic can do. They will throw hadees (or hadith to you Arabophiles) at you as if that in and of itself constitutes any rational argument (and I'm not even getting into the theological issues of which hadees is credible and which suspect, that different schools of jurisprudence have different opinions on). Such is the power of irrational dogma that even recalling the fact that the Quran itself encourages, at numerous points, people to use their minds (i.e. logic, rationality) is brushed aside as irreligious.

I am not advocating that science has all the answers to everything - it doesn't, and the realm of the spiritual is not the domain of science in any case. But yes, science is a process through which we have come to understand more and more about the physical world around us and it posits theories based on evidence, not on mere belief. These theories, which may be overturned by new evidence, are the most plausible explanations at the time of how or why things are the way they are. You can well argue against a theory using evidence that contradicts it. But you cannot, repeat cannot, argue against it just on the basis that you believe something is different.

And this is my problem with the bizarre new post-modern dialectic that seems to pervade the world these days and which is evidenced in some of the comments we get on this blog. Everything is not equally valid, especially if it originates from different planes of thought like religion and science. (Personally, I don't even see the contradiction between being a Muslim and accepting the principles of science, and it seems to me a selective reading in any case, since mullahs use all sorts of products based on scientific principles when it suits them.) This is the new cop-out: claiming you can base analyses on nothing more than your feelings. A sort of 'I feel it therefore it's true.' But you just cannot pit your cherished belief as a valid counter to empirical evidence or reasoned logic. Or rather, you can if you want, but we will make fun of it.

Just in case you thought the irrationality of religious belief  is limited only to places like Pakistan's Ruet-e-Hilal Committee, here's a handy reminder of how the whole world suffers from it. First see the following spoof video below and then follow it up with the real video that it satirizes...

Maybe somebody should enter Mufti Muneeb et al into the Miss USA pageant, based obviously merely on their rejection of logic.

The Fraternity of the Amygdala

What do the following people have in common?


















From top: former US President George W. Bush, Jamaat-e-Islami chief Syed Munawwar Hasan, Dutch MP Geert Wilders, former Australian PM John Howard, Nawai Waqt owner Majid Nizami, The News' Editor Investigations Ansar Abbasi, French President Nicolas Sarkozy, former British PM Margaret Thatcher, US Pastor Terry Jones, anti-'Ground Zero Mosque' campaigner Pam Geller, former ISI chief Lt. Gen (retd) Hamid Gul, media personality Zaid Hamid, Indian Shiv Sena supremo Bal Thackeray, political analyst Shireen Mazari, PML-Q chief Chaudhry Shujaat, and US politician Sarah Palin 


No, it's not what you're thinking, though that's true as well.

They all apparently have large right amygdalas (or amygdalae to the more semantically correct).

Finally, thanks to the latest brain-mapping research, publicized in the papers today, we can understand what it  is that sets these folks apart.

According to the AFP report published in Dawn today:


Brain structure differs in liberals, conservatives: study
WASHINGTON — Everyone knows that liberals and conservatives butt heads when it comes to world views, but scientists have now shown that their brains are actually built differently.
Liberals have more gray matter in a part of the brain associated with understanding complexity, while the conservative brain is bigger in the section related to processing fear, said the study on Thursday in Current Biology.
"We found that greater liberalism was associated with increased gray matter volume in the anterior cingulate cortex, whereas greater conservatism was associated with increased volume of the right amygdala," the study said.
Other research has shown greater brain activity in those areas, according to which political views a person holds, but this is the first study to show a physical difference in size in the same regions.
"Previously, some psychological traits were known to be predictive of an individual's political orientation," said Ryota Kanai of the University College London, where the research took place. "Our study now links such personality traits with specific brain structure."
The study was based on 90 "healthy young adults" who reported their political views on a scale of one to five from very liberal to very conservative, then agreed to have their brains scanned.
People with a large amygdala are "more sensitive to disgust" and tend to "respond to threatening situations with more aggression than do liberals and are more sensitive to threatening facial expressions," the study said.
Liberals are linked to larger anterior cingulate cortexes, a region that "monitor(s) uncertainty and conflicts," it said. "Thus, it is conceivable that individuals with a larger ACC have a higher capacity to tolerate uncertainty and conflicts, allowing them to accept more liberal views."
It remains unclear whether the structural differences cause the divergence in political views, or are the effect of them.
But the central issue in determining political views appears to revolve around fear and how it affects a person.
"Our findings are consistent with the proposal that political orientation is associated with psychological processes for managing fear and uncertainty," the study said."

Yup, like little reptiles baring their poisonous fangs, they're just scared.

I can also see 'Is your anterior cingulate cortex well developed?' becoming a standard pick-up line.
