The public flashpoint between religion and science is found in the issue of creationism and evolution. Other issues, such as the sun revolving around a stationary earth, are now found in the dustbin of history. As visible as this issue is in public life, I have come to believe that other, more subtle, factors fuel the discomfort and conflict between the two fields. What brought me to this awareness was reflecting on my discontent with sermons.
Even the occasional superb sermon—important topic, clear formulation, and engaging presentation—left me with a low-level vexation. It took years to focus on this ongoing annoying feeling and, then, even longer to identify its cause: not what was said, as I kept thinking, but the process shaping what was said. That, then, led to focusing on the different ways that scientists and ministers work, think, and articulate their views.
Minister’s sermons are, almost without exception, deductively shaped. Deductive reasoning works from the general to the specific, often called the ‘top-down’ approach. As a deductive endeavor, sermons follow the pattern of a Bible verse read, followed by an exposition, which often takes the form of three points. That deductive thinking process becomes ingrained both by listening to sermons and in seminary training.
In contrast, there is inductive thinking. I learned the difference in college philosophy; a difference, though, that never worked its way into my everyday consciousness. Inductive thinking moves from observations to generalizations, a ‘bottom-up approach.’ Inductive thinking is more the mode of scientists, and starting out to be a scientist, it is natural to me
Actually, I don’t think anyone is fully encased in either deductive or inductive thinking. Both types of thinking are used in the crucible of daily life. A child constantly lying will lead a parent to generalize about the cause (inductive). At the same time, a firm parental curfew is often imposed, with consequences, for disobedience (deductive). Parents engage in both kinds of behavior. Opinions and decisions in our daily lives are based both on gut feelings, intuitions, emotions, impulses and learned skills (inductive) and on the logic of reasoned conclusions, principles, and convictions (deductive).
Yet, I believe that for religious and scientific professionals, working in their respective fields, either deductive or inductive thinking dominates the habit of mind. It may be that the tendency to one or the other mode of thinking is a given in infancy, but each is honed in professional education and in professional work. Thus, inductive and deductive reasoning—having a marked impact on beliefs and values, decisions and actions—are so ingrained that someone speaking in the other mode can seem strange, foreign, or even wrong.
Acknowledging this difference in our mode of thinking is a way for religionists (predominantly deductive thinkers) and scientists (predominantly inductive thinkers) to begin a more fruitful dialogue. Attending to the truths that we derive from ancient texts expands our own wisdom. Attending to the truths that come from generalizing on our experiences and experiments leads us into important knowledge that adds to the ongoing wisdom of human life.
Reading a text of a new scientific discovery continues to be more satisfying for me than listening to a sermon. However, with my new understanding of why that is, I find I am more relaxed at sermon time. Now I wonder if the minister with whom I shake hands notices a difference.
