Modern science has assumed many of the roles traditionally played by religion and, as a result, is often mistaken for just another religion; one among many. But the situation is rather more complicated and many of the claims that science is not a religion come across as a claim that science is The One True Religion. In the past, religion has supplied answers to the basic questions of how the universe originated, how people were created, what determines morality, and how humans relate to the rest of the universe. Science is slowly but surely replacing religion as the source of answers to these questions. The visible universe originated with the big bang, humans arose through evolution, morality arose through the evolution of a social ape and humans are a mostly irrelevant part of the larger universe. One may not agree with science’s answers but they exist and influence even those who do not explicitly believe them.
More importantly, through answering questions like these, religion has formed the basis for people’s worldview, their overall perspective from which they see and interpret the world. Religious beliefs and a person’s worldview were frequently so entangled that they are often viewed as one and the same thing. In the past this was probably true, but in this modern day and age, science presents an alternative to religion as the basis for a person’s worldview. Therefore science is frequently seen as a competing religion not just the basis of a competing world view. Despite this, there is a distinct difference between science and religion and it has profound implications for how they function.
The prime distinction was recognized at least as far back as Thomas Aquinas (1225 – 1274). The idea is this: Science is based on public information while religion is based on private information, information that not even the NSA can spy on. Anyone can, if they wait long enough, observe an apple fall as Sir Isaac Newton (1642–1727) did, but no one can know by independent observation what Saint Paul (c. 5 – c. 67) saw in the third heaven. Anyone sufficiently proficient in mathematics can repeat Albert Einstein’s (1879 – 1955) calculations but no one can independently check Joseph Smith’s (1805 – 1844) revelations that are the foundation of Mormonism, although additional private inspiration may, or may not, support them. As a result of the public nature of the information on which science is founded, science tends to develop consensuses which only change when new information becomes available. In contrast, religion, being based on private information, tends to fragment when not constrained by the sword or at least the law. Just look at the number of Christian denominations and independent churches. While not as fragmented as Christianity, most major religions have had at least one schism. Even secularism, the none-of-the-above of religion, has its branches, one for example belonging to the new atheists.
The consensus-forcing nature of the scientific method and the public information on which it is based lead some to the conclusion that science is based on objective reality. But in thirty years of wandering around a physics laboratory, I have never had the privilege of meeting Mr. Objective Reality—very opinionated physicists, yes, but Mr. Objective Reality, no. Rather, science is based on two assumptions:
- Meaningful knowledge can be extracted from observation. While this may seem self-evident, it has been derided by various philosophers from Socrates on down.
- What happened in the past can be used to predict what will happen in the future. This is a sophisticated version of the Mount Saint Helens fallacy that had people refusing to leave that mountain before it erupted because it has not erupted in living memory.
Science and religion are, thus, both based on assumptions but differ in the public versus private nature of the information that drives their development. This difference in their underlying epistemology means that their competing claims cannot be systematically resolved; they are different paradigms. Both can, separately or together, be used as a basis of a person’s worldview and it is here that conflict arises. People react rather strongly when their worldview is challenged and the competing epistemologies both claim to be the only firm basis on which a worldview can be based.
