Science, Rationality, and a Healthy Belief in God

During my time on Twitter, I have dealt with quite an assortment of individuals, ranging from COVID-19 and global warming deniers, 2020 election skeptics, and antivaxxers, to proponents of the 911 and chemtrail conspiracies, creationists, Flat Earthers, and QAnon. Apart from these people, I have also had to deal with a group of people whom I had not expected to cross paths with: militant atheists! But here I am not talking about people merely claiming that God does not exist or people pushing for freedom from religion. When I say “militant atheists”, I mean people who claim that a belief in God is incompatible with rational thinking. These people often insult believers calling them stupid or other monikers, while claiming that the belief in God has no place in a mind devoted to rationality and science. I find this claim surprising because the concept of God is beyond the realm of science. It cannot be proven or disproven by science. Viewed from this vantage point, in fact, atheism is not a rigorous intellectual position rationally grounded in evidence and facts, but rather just another belief.
 
In any case, the claim that believers are somehow stupid or irrational is simply not true. For example, when it comes to scientists, some of the greatest scientific minds in the history of science as well as good number of contemporary scientists of renown (including Nobel Prize winners) have been or are believers. Several examples are Nicolaus Copernicus, Blaise Pascal, Francis Bacon, Galileo Galilei, Johannes Kepler, Rene Descartes, Gottfried Leibniz, Isaac Newton, Leonhard Euler, Antonie van Leeuwenhoek, Antonie Lavoisier, Louis Pasteur, James Clerk Maxwell, Michael Faraday, John Dalton, Max Planck, Robert Millikan, Werner Heisenberg, Arthur Compton, Albert Einstein, John Eccles, Gerty Cori, Joseph Murray, Freeman Dyson, Antony Hewish, and Peter Grunberg.
​

​A Pew Research Center poll of scientists in 2009 found that, while the proportion of scientists that believe in God is lower than that of the general population, about 33% of scientists believe in God while 18% believe in a universal spirit or higher power. The point is that rational thinking is not necessarily hindered by belief in a God, spirit, or a higher power. Having said that, everything depends, of course, on what you believe, how you believe it, and your circumstances. Take for example the belief in creationism. If you are a scientist who believes that the world is 10,000 years old, you will have problems if you work in fields such as geology or astronomy. If you don’t accept evolution, you will have problems if you work in fields such as biology, genetics, or molecular biology. On the other hand, if you are a scientist in the field of metallurgy, belief in creationism may not affect your work at all.
 
I believe in God (although not the God depicted by traditional religions), and I don’t believe myself to be irrational or stupid. I also I do not find my belief to be in contradiction with science, as I subscribe to the proposal by the late Harvard paleontologist, Stephen Jay Gould, that science and religion have “non-overlapping magisteria” (NOMA). This means that science and religion have different areas of expertise, and rather than be in conflict with each other they should complement each other because science lacks what religion has and vice versa. Things such as values, morals, ethics, right and wrong, good and bad are the realm of religion. On the other hand, the behavior of matter and energy in the world around us is the realm of science. Religion and related disciplines should guide us in navigating the tricky maze of moral choices that we make throughout our lives. But science should guide us in choosing which beliefs to accept, modify, or discard when aspects of these beliefs clash with reality. Of course, there are some areas of friction between science and religion, but the goal is to deal with these cases in a way that endeavors to maximize the separation between the areas of competence of the two disciplines.
 
When it comes to the belief in a God, spirit, or a higher power, I distinguish two modalities. The first modality occurs when individuals come to accept the existence of God through a process that involves faith and evidence, facts, and reason. I consider this a healthy belief in God because there is an intellectual element involved in the process.
 
The second modality is one that occurs when the process described in the first modality is deficient or absent. This occurs, for example, when individuals believe in God because they were taught to believe in God, or because they grew up surrounded by people who believed in God. In these cases, the belief in God is just a form of social inertia. Another way of believing in God within this second modality is through a highly emotional event that may have involved a conversion from living a wicked life, or at least a life a person felt bad about, into being a better person. For these people the mere fact that they changed their lives is proof that God exists and made this happen and no further analysis is necessary. This second modality of belief in God is unhealthy, because it is unexamined and therefore prone to the uncritical acceptance of the beliefs of groups or churches that may hold views of the world that are contrary to science and reason.
 
Most scientists who believe in God, a spirit, or a higher power, believe in them in a reasonable way, because they allow their beliefs to be tempered by evidence, facts, and reason. For example, evangelical protestants tend to have creationists views that deny the age of the Earth and evolution while accepting that there was a universal flood (although there are subtleties to this claim). In the Pew Research Center poll mentioned above, while 28% of the general public claimed an evangelical protestant affiliation, only 4% of scientists did.
 
To recap, I don’t consider the belief in God to be anathema to rational thinking, but I do consider that the unexamined belief in God is unhealthy, as it may lead to the denial of the reality around us as discovered by science.
