The often strained relationship between science and religion has become particularly combative lately. In one corner we have scientists such as Richard Dawkins and Steven Pinker who view religion as a relic of our superstitious, prescientific past that humanity should abandon. In the other corner are religious believers who charge that science is morally nihilistic and inadequate for understanding the wonders of existence. Into this breach steps Francis Collins, who offers himself as proof that science and religion can be reconciled. As leader of the Human Genome Project, Collins is among the world's most important scientists, the head of a multibillion-dollar research program aimed at understanding human nature and healing our innate disorders. And yet in his best selling book, The Language of God, he recounts how he accepted Christ as his savior in 1978 and has been a devout Christian ever since. "The God of the Bible is also the God of the genome," he writes. "He can be worshiped in the cathedral or in the laboratory." Recently Collins discussed his faith with science writer John Horgan, who has explored the boundaries between science and spirituality in his own books The End of Science and Rational Mysticism. Horgan, who has described himself as "an agnostic increasingly disturbed by religion's influence on human affairs," directs the Center for Science Writings at the Stevens Institute of Technology in Hoboken, New Jersey.
