Faith: Science and Religion

Science and religion use the word faith in two very different ways. Speaking of faith as it relates to the expectation that the earth will rotate around to face the sun again tomorrow is quite different than the faith praised in Hebrews 11 ("Now faith is being sure of what we hope for and certain of what we do not see"). To suggest that science is also based on faith, because some of the foundational laws of physics are not experimentally demonstrated but treated as "givens," is misleading.

True, Carl Popper (the influential philosopher of science) noted that the financial disclaimer "Past performance is no guarantee of future returns" is also true of inductive reasoning. But, just like investors view past performance as an indicator of future returns, many regard Popper's critique of induction as a kind of reductio ad absurdum argument - we have good reason to expect natural laws to remain in effect. Just because we can't be absolutely certain does not mean that we have no certainty at all. We go with successful investment funds because we expect the future to look like the past. Unlike funds, however, we so far have found no exceptions to the rule that the present continues to look like the past, as far as the laws of physics go - and so it is reasonable to expect the future to look like the past as well. This is a far cry from the Biblical notion of faith.

The Bible commends faith that holds firm in the absence of evidence. Good science encourage faith (if that is the right world at all) only in the face of compelling (even if not irrefutable) evidence.

Science is just an extension of careful observation and reasoning. We've been doing science for thousands of years. What enabled what we think of as modern science to transform the world's culture in a few hundred years seems to be a combination of the right political climate and a rejection of traditional explanations ("As above, so below"). That, and methodological naturalism.

Taken from this perspective, science and faith don't present any more of a conflict than did faith and the natural world for the author of Hebrews. The attempt to make science just another faith (and a religion on top of that) looks to me to be an attempt at undercutting the demand for faith. The author of Hebrews argues not that science is just as uncertain as religion, but that we have faith in the face of uncertainty. Rather than tear down science, Hebrews urges, build up faith.
