Can God and science mix? I suppose that the third season of Through the Wormhole would be the place to look. The entire season has a distinctly metaphysical feel to it, so it is no surprise that the final episode is entitled “Did We Invent God?” It’s also no surprise that, like the other metaphysical issues explored, no resolution is really offered. Interviewing psychologists and neurologists, the show attempts to parse how scientists might address the question of God’s reality. God, of course, being immaterial, is normally understood not to be a subject discerned by science. So instead of putting God under the microscope, human perceptions of God will have to do. Everything from theory of mind to magical beliefs are probed to find hints of whence this strange idea of God might have come. The answer: we don’t know.
The more I pondered this, the more the same result reflected on science itself. When I was growing up I thought science was the truth. If science “proved” something, there was no arguing the point. I have come to realize, however, that science must be falsifiable to be science. That means it is potentially wrong. Not that it goes as far as Creationists take it to say that something is “only a theory,” but rather that science is the best explanation that we have at the moment. Future discoveries could falsify what we now know and the science textbooks would have to be rewritten. The difference here with religion is that most belief systems do not admit of this possibility. The truth has already been revealed, and there is no adding to or taking from it. God is not falsifiable. As stated above, God is not subject to science.
I don’t expect these observations of mind to change anybody’s ideas of the world. I do hope, however, that they make clear that science and metaphysics find themselves in similar situations. Both strive to know the truth. Neither can know if they’ve arrived. Both can believe it. The final episode of the season raises this point starkly. People are hardwired to believe. What they believe in is open to many possibilities, but believe they will. From my earliest days I have taken belief very seriously. What I have believed has changed over the decades, but at each step along the way I believed it was the truth at that time. I don’t know the truth. Nobody does. We all, whether scientist or religious, believe that we have found it. At the moment.
