Heredity and Humanity
anexilus sent in this essay by the director of the National Human Genome Research Institute. He discusses genes, nature and nurture, and tries to allay fears that Gattaca will come to pass. Good reading.

"The notion that science alone holds the secrets of our existence has become a religion of its own. The faith of Dawkins and others in biology seems even greater than the faith of the simple believer in God. Science is the proper way to understand the natural, of course; but science gives us no reason to deny that there are aspects of human identity that fall outside the sphere of nature, and hence outside the sphere of science."
While the rest of the article was first-rate, I have to wonder what the authors were thinking when writing the above. Whether they realize it or not, the authors are falling back on that classic logical fallacy that religious groups everywhere have used to argue the creation side of the creation/evolution debate: "there is no evidence for your argument, so mine must be correct."
Science is about what is observable, and to their credit, the authors admit this in the very next paragraph. But to state that a decision to believe only in the observable is tantamount to an act of "faith" is silly. Science is about observation. When you decide that something may never be observable (i.e. because it may be "supernatural"), you bias yourself beyond repair.
It isn't "faith" to believe that our behaviors are a result of complex natural phenomena--it is a refusal to place credence in that which is unobservable, and therefore undefendable. And *that* is the exact opposite of faith.
Let's try not to let fact interfere with our speculation here, OK?
