Without God
Nobel prize winning physicist Steven Weinberg gave a lecture at Harvard earlier this year exploring how religion and science are in conflict--but not in the superficial ways we see in debates over creationism. His lecture is now available in the New York Review of Books:
Let's grant that science and religion are not incompatible—there are after all some (though not many) excellent scientists, like Charles Townes and Francis Collins, who have strong religious beliefs. Still, I think that between science and religion there is, if not an incompatibility, at least what the philosopher Susan Haack has called a tension, that has been gradually weakening serious religious belief, especially in the West, where science has been most advanced. Here I would like to trace out some of the sources of this tension, and then offer a few remarks about the very difficult question raised by the consequent decline of belief, the question of how it will be possible to live without God.. . .
The problem for religious belief is not just that science has explained a lot of odds and ends about the world. There is a second source of tension: that these explanations have cast increasing doubt on the special role of man, as an actor created by God to play a starring part in a great cosmic drama of sin and salvation. We have had to accept that our home, the earth, is just another planet circling the sun; our sun is just one of a hundred billion stars in a galaxy that is just one of billions of visible galaxies; and it may be that the whole expanding cloud of galaxies is just a small part of a much larger multiverse, most of whose parts are utterly inhospitable to life. As Richard Feynman has said, "The theory that it's all arranged as a stage for God to watch man's struggle for good and evil seems inadequate."
Most important so far has been the discovery by Charles Darwin and Alfred Russel Wallace that humans arose from earlier animals through natural selection acting on random heritable variations, with no need for a divine plan to explain the advent of humanity. This discovery led some, including Darwin, to lose their faith. It's not surprising that of all the discoveries of science, this is the one that continues most to disturb religious conservatives. I can imagine how disturbed they will feel in the future, when at last scientists learn how to understand human behavior in terms of the chemistry and physics of the brain, and nothing is left that needs to be explained by our having an immaterial soul.
. . .
There is a fourth source of tension between science and religion that may be the most important of all. Traditional religions generally rely on authority, whether the authority is an infallible leader, such as a prophet or a pope or an imam, or a body of sacred writings, a Bible or a Koran. Perhaps Galileo did not get into trouble solely because he was expressing views contrary to scripture, but because he was doing so independently, rather than as a theologian acting within the Church.
Of course, scientists rely on authorities, but of a very different sort. If I want to understand some fine point about the general theory of relativity, I might look up a recent paper by an expert in the field. But I would know that the expert might be wrong. One thing I probably would not do is to look up the original papers of Einstein, because today any good graduate student understands general relativity better than Einstein did. We progress. Indeed, in the form in which Einstein described his theory it is today generally regarded as only what is known in the trade as an effective field theory; that is, it is an approximation, valid for the large scales of distance for which it has been tested, but not under very cramped conditions, as in the early big bang.
We have our heroes in science, like Einstein, who was certainly the greatest physicist of the past century, but for us they are not infallible prophets. For those who in everyday life respect independence of mind and openness to contradiction, traits that Emerson admired—especially when it came to religion—the example of science casts an unfavorable light on the deference to authority of traditional religion. The world can always use heroes, but could do with fewer prophets.
Weinberg then argues that living life with religion is not without its problems.
Read it all here. What do you think?

Weinberg writes, "Let's grant that science and religion are not incompatible—there are after all some (though not many) excellent scientists, like Charles Townes and Francis Collins, who have strong religious beliefs."
I'm not sure what he means by "some (thought not many) excellent scientists," beyond his estimation of his immediate associates or some sense of the most famous. I grew up in the communities of scientists and researchers of a major state land grant university and a major national research laboratory, and within those communities alone there were many excellent scientists - in the sense of doing good research, following proper procedures and reaching meaningful results, and getting regularly published - who were persons of deep faith. Indeed, it was a colleague of my father's, one who had been with him when both were pursuing their doctorates, who introduced my family to his family's Episcopal parish. I continue to work in health care, another arena of "excellent scientists," in which some sense of faith is the norm rather than the exception.
I acknowledge the tensions noted; but to describe reflective scientists as opposed to non-reflective people of faith is to maintain the same "us vs. them" polarity that has characterized the discussion for a long time.

Weinberg writes of "the special role of man, as an actor created by God to play a starring part in a great cosmic drama of sin and salvation."
I see a response to that issue in the writings of CS Lewis and Madeleine L'Engle who both saw Humanity's fall from the place God had assigned us - and earth - in God's plan as having no effect on other planets.
Of course our primitive mythology makes us look important but - we know this from Star Trek - as we mature, we'll realise we're not that central at all. As a race we are important to God - as important as any others. So God chose to save us... but that doesn't mean the rest of the universe needs saving.
Man's role in the "Great Cosmic Drama" is revealed to pertain only to him. But that discounts neither the importance of his salvation nor the reality of the Cosmic issues.
By citing fictional works of Roddenberry, Lewis and L'Engle, I don't mean to make light of this. But his claim is as mythological as our own in this matter. Until we meet a race that is Not Fallen - and until we can know they are not - we might as well imagine mankind's claims of a central role in this drama to be valid.

A challenging concept, to be sure.
From my humble POV, I think I would have difficulty accepting another life-form AS a "race" (that is, as sentient beings), unless they had the Freedom to choose Right from Wrong---which could, in turn, only be known through comparison (they were free to choose Right from Wrong, only because they had chosen Wrong, in hindsight).
I honestly think that---whatever our SciFi fantasies---the odds of communicating w/ another intelligent life-form are so infinitesimally small, that we will never have to deal w/ the "Is Jesus ONLY the Savior of Earth?" question. ;-/

It's hard to put my finger on just what this means, but I found reading Weinberg's articulation of his skepticism comforting in a way, or maybe grounding. I felt like I was in the territory that got early Christians (like Buddhists) judged to be atheists. And I remembered Farley Mowat in Never Cry Wolf feeling so overwhelmed at the vast beauty of the northern territories in Canada that he said he wanted to cry 'THANK YOU' at the top of his lungs, though he didn't believe there was any cosmic ear to hear him. There's a place where tragic skepticism, humbly held, starts to converge toward faith.

(I think I accidentally erased this post when I signed in). Something about the way Weinberg writes his skepticism seems more gift than challenge, comforting even. It reminds me that the earliest Christians were judged atheists by Roman society, as Buddhists are often declared atheists. I think an open-hearted skepticism, a genuine love for people and a grateful appreciation of beauty starts to converge toward faith. I'm reminded of Farley Mowat in Never Cry Wolf describing how he couldn't help but cry out a huge THANK YOU to the empty beauty of the northern territories, even though he believed though was no maker or divine ear to hear him.
