As someone who loves both religion and science, I often struggle with how they interact.
Are they in opposition to each other? Do they need to be reconciled? What happens when new scientific knowledge challenges the tenets of my faith?
The Contrast model is probably the most common way people speak about the interaction of science and religion. Often, this view is boiled down to the idea that "science deals with 'how' and religion deals with 'why.'"
Stephen Jay Gould popularized it with the phrase "Non-Overlapping Masteria" (NOMA), which he describes as follows: "The magisterium of science covers the empirical realm: what the Universe is made of (fact) and why does it work in this way (theory). The magisterium of religion extends over questions of ultimate meaning and moral value. These two magisteria do not overlap."
But there are two problems with this paradigm. First, religion has theories about what the universe is made of -- for example, Jewish tradition has statements about the way the world came into being and why the world is the way it is. And science is now talking about morality and even meaning, with books like Sam Harris' "The Moral Landscape" about the science of morality and "The Brain and the Meaning of Life" by Paul Thagard about neuroscience and meaning. Thus, the magesteria, in fact, do overlap.
Second, and perhaps even more importantly, it's simply not true that science talks only (or even primarily) about "how" -- there's a lot of "why" in there, asking questions like, "Why is there something instead of nothing? Why do our brains work in the way that they do?" Similarly, religion doesn't talk only (or even primarily) about "why" -- there's a lot of "how" in there, asking questions like, "How do did humans come to be? How should we act in this world?"
The Concert model is the opposite of the Contrast model, as people try to directly reconcile science and religion. It is another attractive outlook to those who are both dedicated to their faith and committed to reason, since it means they would not have to reject either. This model makes claims such as the concept of a "day" in Genesis may actually be billions of years, or that the crossing of the Red Sea was actually finding a swamp that could be crossed at low tide.
But here, too, there are problems with this view. After all, science is always changing, discovering new data and revising theories. If science and religion are in concert, what happens to religious faith when new scientific evidence arises? Indeed, not only physics and biology but also human sciences such as archaeology, political science and history are helping us understand who we are, why we do what we do and our place in the universe. So if religious faith is based on science, what happens when science presents new evidence?
Indeed, this model makes it hard to do a critical analysis of biblical texts, and that type of study frequently leads to a crisis of faith. In order for it to work, this model requires significant mental gymnastics, and forces people to maintain only a surface understanding of both science and religion.
The Conflict model is the paradigm that gets the most press, and it claims that religion and science are inherently incompatible. It's the idea that if you buy into one, you must reject the other. This worldview is exemplified by Richard Dawkins and Christopher Hitchens on one side, and people who deny evolution because it contradicts the Bible on the other.
But while this outlook generates the most passion from people on the extremes, there are a vast number of people who do not buy into it.
An article in The Huffington Post describes recent work by sociologist Elaine Ecklund, who
...interviewed 275 tenured and tenure-track faculty members from 21 research universities in the United States. Only 15 percent of respondents said religion and science were always in conflict, while 15 percent said the two were never in conflict. The majority, 70 percent, said religion and science are only sometimes in conflict.
Similarly, a study from Pew Research Forum showed that "a solid majority of Americans (61 percent) say that science does not conflict with their own religious beliefs. Even among those who attend worship services at least once a week, a slim majority (52 percent) sees no conflict between science and their faith."
Thus, while zealous advocates on each side often dominate the discussion, there is a large silent majority who do not see science and religion as inherently in conflict.
The bigger problem is that while the Conflict model produces a lot of heat, it rarely creates light. It regularly devolves into unproductive arguments and ad hominem attacks, and causes both scientists and religious people to become either overly aggressive or feel themselves to be "victims" of the other side.
This is the outlook that I find most resonant. In this model, science and religion can remain in their own spheres, but when it is appropriate, they can also mutually inform each other and provide us with a variety of ways to help us know what it means to be human. Indeed, its great value is that it reminds us that both religion and science have to be understood in the context of human experiences, because both religion and science are human endeavors.
The Contact model reminds us that science is not independent of the scientists who pursue their field of inquiry. After all, while the universe may be 13.7 billion years old, and humans may have evolved on the African savannah, it has only been since modern times that human beings have sought to undertake a rigorous understanding of fields like cosmology, paleontology, psychology, neuroscience and biochemistry. We have to remember that not only does scientific knowledge provide information, it is deeply influenced by the passions, the curiosity and the personal experiences of the scientists who pursue it.
Similarly, our own personal experiences influence our religious outlook. People's feelings about religion are naturally affected by how they were raised and what has happened in their own lives. In the words of Rabbi Laura Geller, "All theology is autobiography." And while religion is older than science, it is still a human creation, helping us structure our human experiences, and asks deeply human questions like, "How should I act? What should I value? Who should I choose to associate with?"
When we place science and religion in the context of human experiences, we recognize that both science and religion are driven by human needs and are victim to human foibles. The Contact model thus encourages humility in both science and religion, reminding both sides that there are things we do not know, and things we will never know.
So the other crucial piece to bear in mind for the Contact model is that "religion" and "God" are two separate things. "God" is bigger than any one human being or group of people; "religion" is our particular attempt to understand God, and is necessarily limited. As Rabbi Abraham Joshua Heschel taught: "[R]eligion for religion's sake is idolatry ... The human side of religion, its creeds, its rituals and instructions is a way rather than the goal. The goal is 'to do justly, to love mercy and to walk humbly with your God.' (Micah 6:8)" ("I Asked for Wonder," p.40-41)
So for those of us who feel connected to God, when we forget that religion is not Divine, but human, we can easily fall into the trap of arrogance and narrow-mindedness. Micah thus reminds us that justice, mercy and humbleness are truly the most important values.
Indeed, our ultimate purpose in life is to strengthen ourselves, both as individuals and as a society. Science does that by giving us a fuller understanding of the world, by advancing knowledge, and by examining the relationship between theory and evidence. Religion does that by giving us a sense of purpose, by strengthening communities, and by giving us a potential glimpse of the Divine.
When we remember that both science and religion are human enterprises, we can remember that the most important question isn't whether they need to be viewed separately, or if they can be reconciled, or if they are inherently in conflict.
The most important question is: How are they being used?
