I would call it faith in rationalism. After all, it has had an extremely successful history. Anytime we choose to pursue a natural (
or rational) explanation over a spiritual or (
irrational) it has always lead to the discovery of obvious truths. It has also lead to undeniable advancements in technological achievement.
A simple example would be that we could either have "
faith" that some invisible God (
or invisible demons) are the cause of disease. Or we could look into the matter for natural causes and find them, thus revealing the
truth of the cause of diseases, as well as advancing us with potential prevention and/or cures from diseases.
Which makes more sense? To blindly retain an irrational superstitious belief, or to look into the matter and discover actual
truth?
Mankind has clearly invented via superstition or philosophical guessing, many different ideas of the potential existence of invisible Gods. Many of them contain utter absurdities that have since demonstrated to be clearly false. The obvious example is that disease is caused by demonic possession. This particular example is clearly a claim of Christianity as their Christ cured diseases by supposedly casting out demons from people. Sure, you could now claim that this is just a "
metaphor", by why would you know claim that this was just a metaphor? Because naturalistic investigations into the matter (i.e.
science) has revealed the "truth".
Naturalistic explanations have a profound record of leading to truth and to very useful truths to boot. Our current technological advances in medicine, food production, shelter, even clothing, etc. would not exist had we continued to remain faithful to superstitious belief.
So naturalistic
explanations have proven their worthiness. Superstitious, or spiritual
explanations have been proven to be demonstrably false, as well as being useless.
Also, with so many religious superstitions how could anyone know which one might be true?
Should we believe that the Greek Gods who were living on Mt. Olympus simply left when humans became too inquisitive? And had simply erased all traces of their previous existence?
Should we believe that the Abrahamic God of the Jews created the earth in 7 days a mere 6 or 10 thousands years ago and was ultimately not pleased with his creation and drown out all but a handful of humans to try to rid his creation of sinful people? And then simply erased all the traces of this history by making it appear that the earth is actually 4.5 billion years old and that animals slowly evolved to higher and higher levels of complexity over those billions of years?
Clearly the Jewish superstitious God tales are false. Christianity and Islam merely add more absurdities to those original superstitions. Absurdities that are demonstrably false.
For example, Christianity has Jesus proclaiming that his followers shall be able to do greater works than he. Yet, this very same superstitious religion flat out refuses to allow that anyone has ever lived who has done greater works than Jesus. Not only that, but there aren't even historical rumors of any such people. So these kinds of superstitious tales simply have no merit. They have not only provided us with any obvious truths, but to the contrary they are clearly demonstrably false in what they claim.
Islam of course follows the same unproductive path as Judaism and Christianity proclaiming all manner of demonstrably superstitions but providing no obvious truths or worthwhile discoveries of the true nature of our reality. Science (
or naturalism) has all these religions demonstrably beaten when it comes to the discovery of truth.
We then have other superstitious spiritual philosophies, such as pantheism, and the far eastern religions of Hinduism, Taoism, and Buddhism. While being far closer in their predictions to the discoveries of natural inquiry (i.e. Science) they are still just guesses that offer no demonstrable truths concerning many of their superstitious claims.
So Naturalists, simply have faith in rational thought. And this is because rational thought, and rational inquiry have lead to obvious truths that cannot be denied.
So why shouldn't we place our "faith" in the system of inquiry that has produced the most obvious, useful, and demonstrable truths?
And why should anyone cling to,
or place faith in, ancient superstitions that are demonstrably false in what they claim?
Is belief in demonstrably false superstitious tales rational?
Can you answer this question?
