"I'm not going to say that it's easy to live without God, that science is all you need. For a physicist, it is indeed a great joy to learn how we can use beautiful mathematics to understand the real world. We struggle to understand nature, building a great chain of research institutes, from the Museum of Alexandria and the House of Wisdom of Baghdad to today's CERN and Fermilab. But we know that we will never get to the bottom of things, because whatever theory unifies all observed particles and forces, we will never know why it is that that theory describes the real world and not some other theory," writes Steven Weinberg, a physicist at the University of Texas at Austin, in a thoughtful essay on the tensions between science and religion (and what he thinks their relationship will mean for the future of belief) in The New York Review of Books.
"Worse, the worldview of science is rather chilling. Not only do we not find any point to life laid out for us in nature, no objective basis for our moral principles, no correspondence between what we think is the moral law and the laws of nature, of the sort imagined by philosophers from Anaximander and Plato to Emerson. We even learn that the emotions that we most treasure, our love for our wives and husbands and children, are made possible by chemical processes in our brains that are what they are as a result of natural selection acting on chance mutations over millions of years. And yet we must not sink into nihilism or stifle our emotions. At our best we live on a knife-edge, between wishful thinking on one hand and, on the other, despair."
