When scientists underestimate complexity, they fall prey to the perils of unintended consequences. The parables of such scientific overreach are well-known: foreign animals, introduced to control pests, become pests in their own right; the raising of smokestacks, meant to alleviate urban pollution, releases particulate effluents higher in the air and exacerbates pollution; stimulating blood formation, meant to prevent heart attacks, thickens the blood and results in an increased risk of blood clots in the heart. But when nonscientists overestimate [italicized, sic] complexity- 'No one can possibly crack this [italicized, sic] code" - they fall into the trap of unanticipated consequences. In the early 1950s , a common trope among some biologists was that the genetic code would be so context dependent- so utterly determined by a particular cell in a particular organism and so horribly convoluted- that deciphering it would be impossible. The truth turned out to be quite the opposite: just one molecule carries the code, and just one code pervades the biological world. If we know the code, we can intentionally alter it in organisms, and ultimately in humans. Similarly, in the 1960s, many doubted that gene-cloning technologies could so easily shuttle genes between species. by 1980, making a mammalian protein in a bacterial cell, or a bacterial protein in a mammalian cell, was not just feasible, it was in Berg's words, rather "ridiculously simple." Species were specious. "Being natural" was often "just a pose.
I’d like to share with you a parable: the parable of Bob the Angel.A girl was walking down a darkly lit city street late at night. A man jumped out from the shadows and attacked her, suddenly she was suffocating and disoriented as hands clasped around her neck and the force of his attack started to push her down. She tried to yell as she struggled to pull his arms from her neck while she crumpled backwards to the ground, “God . . . help me!” The next thing she remembers—just as the fear consumed her, and right as she disappeared into the misery and despair of helplessness—was a loud crash and an explosion of glass which rained down upon her and her attacker. The assailant’s lifeless body was suspended above her, held from collapsing on her by an unknown force, and then pulled away from hovering over her and dropped onto the pavement beside her. She opened her eyes in the faint shadowy light, to see black matted hair and a long, black beard framing the eyes of a man. The smell of alcohol on his breath would have knocked her out if the adrenaline was not still trilling through her veins. There he stood, God’s angel, off-kilter and drunk, with a broken whiskey bottle in his hand. “You probably shouldn’t be walking through here this late at night,” was all he said as he turned away.“Wait! What’s your name?” she asked, still stunned half sitting up on the ground.All she heard as he walked away was his trailing voice calling, “Bob’s as good as any. . . .” An angel is a messenger, and sometimes we only want letters sent in white envelopes with beautiful gold print, when sometimes a simple “no” on the back of a gum wrapper is what we are offered. Every postcard from heaven does not come with a picture of the sunset there, nor should it. If it is an answer we want, an answer we will get. As far as pretty postcards, there are many others willing to send us that. If not harps and gold-tipped wings, what then is the mark of an angel? An answer which pierces your soul, and which inspires a question that invites you to look outside of yourself and up to God.
