God gave man dominion…

Saturday, June 27th, 2009

Humans are evolution’s only experiment with higher intelligence, as is evidenced by our mastery of mathematics, language, engineering, space travel, medicine, and many other fields in which we have visibly demonstrated command of the world around us. Sure, dolphins and octopodes may have highly developed brains, but they don’t print books or manufacture nuclear bombs. We’re clearly the smartest things on the planet.

Many people believe that this makes us special; that we are evolution’s end product, the creator’s chosen race, or simply that we are the “highest” form of life. But I mostly reject that idea.

Intelligence is just what we do. Birds fly, sharks have sharp teeth, and humans build cities. This in no way makes us “higher” than any other organism, it just makes us the best at being smart. Nature is full of “best at”s. Cheetahs are the best at running, and if they were capable of designating a “highest” form of life, it would surely be themselves, because the metric they would use would be the one most useful to them as an organism: speed.

An obvious counterpoint is that intelligence makes us “best at” anything we want. Cheetahs can admire our high-speed trains, sharks our knives, and birds our jets. However, it’s useful to remember that despite our intelligence, we are not the most successful earth creatures by any measure. That honor goes to the most inconspicuous of our neighbors: microorganisms. To any objective observer, humans–along with most species of animal–are a fragile lot, perpetually on the verge of extinction. The best way to gauge the “highest” life-form may simply be its ability to perpetuate itself. If that’s the case, the nuclear bomb puts us far lower on the ladder.

The Cross I Bear

Wednesday, June 17th, 2009

I often reflect on my sentiments towards religion, and wonder why I hate it so much. I ask myself why I dedicate so much time to railing against an institution that has done me no more harm than a few shattered delusions and wasted Sundays. I even feel ashamed of this seemingly puerile obsession with denigrating faith, despite a lack of any ostensible wrongdoing on the part of the religious.

However, I’m reminded that there is one grave disservice that religion has done me which I cannot bring myself to forgive. It mutilated my genitals.

Yes, that may seem a hyperbole; even writing it I feel I am being deliberately provocative. But I have to stop and ask myself, am I? Is there any sense in which surgically modifying an unconsenting child’s genitals is not a reproachable human rights violation? Due to its cultural normativity, circumcision may fail to arouse our sense of disgust in the same way footbinding or female genital mutilation do. However, just because we don’t have a gutteral aversion to it does not mean it’s not an egregious act. We tend to look on other cultures’ barbaric rituals with a smug superiority, reassuring ourselves that we’re civilized, but maybe we should turn the lens inward.

Circumcision, is at its root a religious export, and it’s in religion that it takes refuge and perpetuates itself. When a mohel in New York was responsible for the death of a child, no one spoke up against practice of circumcision as a Jewish ritual. Instead, we pussyfooted around the topic, saying that it was merely a problem with the orthodox techniques, or that proper precautions were not taken. No one considered that cutting off part of a child’s penis was inherently wrong. They dare not denounce the religious practice itself, either for fear of being culturally insensitive, or because most of us live in glass houses.

And therein lies the problem. No one will stand up and call this atrocity that it is, because if we don’t respect everyone’s right to have irrational beliefs, then someone may come after our own. Well I won’t feel ashamed for being strident anymore, because we should all have the right to savagely critique one another’s irrationalities; to lay them bare and hack away at them, just like they did to my newborn privates.

Can We Trust Our Brains?

Wednesday, June 3rd, 2009

I have recently been repeatedly confronted with the philosophical quandary of whether or not our perceptions of reality can be trusted, or if our internal models of the world around us are bound to be riddled with flaws and misrepresentations. A fellow blogger has spurred be to put down my thoughts in writing.

I think you have to begin by admitting that we can never know if our senses do justice to reality, because we have no other way to gauge their efficacy than by our senses themselves. However, ultimately, I think they do a pretty damn good job.

I’ve found evidence for this in the fact that a brain is, in its most basic form, an input-output system. Input stimulus: output response to stimulus. Evolution tunes the system to give the proper response to the proper stimulus, and therefore to be faithful to reality. For example, we have a vermicompost box, and when we want to get the worms to move in a certain direction, we expose them to light. They promptly wriggle in the direction of the nearest shade. If their flee response weren’t faithful to reality, they’d fry to death, or waste valuable energy wriggling when there was no sun.

Granted, the human brain is more sophisticated than that, because it has a complex intermediate step of model building based on memory. This apparatus allows synchronic tuning of responses to stimuli, as opposed to letting natural selection tune them. However it’s still just an elaborate version of “when the world is this way, respond in that way.”

Therefore, if you’re not building an accurate model of the world around you, then your brain isn’t performing its function. Evolution should then select for brains that make increasingly accurate models of the surrounding environment, or at least as accurate as any given organism needs (a human needs no sense for surface tension, but a water strider needs no sense for vertical orientation). Sure, there are glitches in the system, and they give rise to models that belie reality, but only in trivial ways: like optical illusions, pareidolia, and religion.

And there’s my daily epiphany: religion belies reality only in trivial ways. The belief that there is an invisible man in the sky who sees everything you do fits neatly into the gaps in our perception in such a way that it cannot be disproven, and it does not (often) dictate our reactions to stimuli. If it interfered with our model-building apparatus in either of these ways, evolution would have–and modern science could have–disposed of it quickly.

In closing, I’d like to analogize the brain to a house; the function of the brain is to construct models of the world, and the function of a house is to protect its inhabitants. You can build a house out of all kinds of things (aluminum, bricks, adobe etc.), and while you’ll have different engineering strategies based on the materials you are using–and different drawbacks with each–the end goal is still to create shelter (in the case of the brain, to build faithful models). Evolution set us on a particular path, with a particular set of materials–namely, the more basic reptilian and mammalian brains–and the drawbacks inherent thereto. The evolutionary history of the brain presents a unique set of obstacles to building a functional model-building apparatus, and has crucially informed its eventual architecture, in the same way selecting Play-Doh as the building material for your house would present a unique set of obstacles to its construction. Surely, it’d be better to choose bricks than Play-Doh, but evolution won’t let you switch materials mid-build, but we got as close as we could. Obviously, the materials we got stuck with weren’t that bad, because we’re still here. And our model building apparatus can’t be that bad either.

Tiller the Baby Killer

Tuesday, June 2nd, 2009

It’s been a long time since I have posted to my blog, because things have been so busy at work and at home, but I feel I have to comment on this.

In case you haven’t been following the news, Dr. George Tiller, who was known for providing late term abortions, was killed this Sunday. He was shot to death while sitting in church.

Now, you may know my position on abortion, which is that it’s a necessary evil (there’s a clever little epigram that says conservatives need to recognize abortion is a necessary evil, liberals that it’s a necessary evil), so we should take steps to reduce the need for them. But I’m also committed to the stance that–for most cases outside of severe deformity of the fetus, or imminent danger to the mother’s life–the later the operation is performed, the more unconscionable it becomes. Still, he didn’t deserve to be killed.

Bill O’Reilly (whose word you should always take with a grain of salt, if not a whole salt lick) would have us believe that Tiller was killing babies right before their heads breached the birth canal, and was calling it “late term.”

I guarantee you he wasn’t. And for a guy who bills himself as ‘No-Spin,’ O’Reilly sure got people spun up over ‘Tiller the Baby Killer.’

Granted, O’Reilly wasn’t directly responsible for inciting the man to murder Tiller, but the baby-killing meme that he gives platform to is dangerous, and his singling out of Tiller is despicable.
