Several atheistic blogs I read are guilty of “scientism.” Scientism is not science but rather deductions and speculations arising out of scientific observations. Truth is truth no matter the source. Scientism, however, sees science and empirical observation as the only source of truth. Consider this definition:
Scientism sees it necessary to do away with most, if not all, metaphysical, philosophical, and religious claims, as the truths they proclaim cannot be apprehended by the scientific method. In essence, scientism sees science as the absolute and only justifiable access to the truth.
Here’s an example from a blog called, Unreasonable Faith
Belief never invented a laser, or pressed a CD, or kept a ‘plane in the air, or restarted a heart – Science has done all of that and more, a whole bunch of times.” And, “Against this staggering work and monumental achievement (the proof that one of Einstein’s theories is correct – DW) on one single scientific project out of hundreds of thousands, there stand some old men in robes, telling us that God did it, because it says so in the nth translation in the chain of some bronze-aged myths written by some camel-herders.
For the moment let’s ignore the ridicule and the reality that many respected scientists believe that “God did it.” More to the point: science and faith are two different things and, thus, not in competition. Faith is defined as, “…the assurance of things hoped for, the conviction of things not seen” (Hebrews 11:1). On the other hand, science is totally based on what can be seen. When interpretation of scientific observations moves beyond the observable, it becomes speculation. Speculation is fine and useful for building hypotheses but it is still speculation. And there’s nothing wrong with speculations as long as they are recognized as such. Just don’t ask me to accept them as incontrovertible truth.
Many religious people have rightly been resistant to speculations contradicting the concept of a Creator. Others have stubbornly held to their own religious speculations that are in obvious contradiction to observable and undeniable facts. This is foolish in light of the reality that observable facts (sans speculations) do not contradict the concept of a Creator God. In truth, some of those facts call loudly for a first cause and a designer.
Science and faith operate in two separate realms. Faith presupposes the existence of a supernatural realm (things not seen). Science can only operate in the natural realm. To place them in competition is ridiculous.
