I have written about how it is relatively easy to come up with animistic religions by having a somewhat overactive agency detector, a feature that provided us an evolutionary advantage by making us less susceptible to predation. The roots of religion, therefore, are quite understandable. How we got to “now,” however requires some more consideration.
For example, over time we have reached a place in which “reason” is set in opposition to “belief” and “faith.” I don’t think this can be laid at the feet of reason for why this is so. So, was reason, ever, the enemy of faith/belief?
We only have written records going back some 5000 years or so, which defines what we mean by written history. Those records show that people had religious faith and used reason for that entire time . . . that is, some people, not all people, did this.
History is punctuated with any number of episodes in which religion ran up against faith. For example, Socrates was executed in 399 BCE (given the grace of being allowed to commit suicide) “refusing to recognize the gods recognized by the state” and of “corrupting the youth” thereby. Since this sort of prosecution (by secular and/or religious elites) happened a great deal, there was a decided downside of using reason applied to the gods. The Spanish Inquisition (and many of the other inquisitions) kept meticulous records of the numbers of people they tortured, executed, and executed by torture for being “heretics.” Some of the records show ordinary people being naively quite atheistic in their “interviews” with the Inquisitors of the Holy Office of the Inquisition. Apparently they had been counseled by their lying eyes and not so much by their incompetent priests.
In the Abrahamic faiths, disdain for reason was hard-wired into scripture. Numerous bits and pieces of their holy books encourage rejection of reason as a guide for one’s life. This, of course, is understandable because religion is a social control mechanism, endorsed by the elites. If a religion is not endorsed by the elites, it doesn’t last long. (Yes, yes, there were folk religions, but did many of them survived the onslaught of the well-heeled, well-organized campaigns for state religions?)
So, the curious thing, in my mind, was how vigorously religious apologists pursued “reasons” why their faith was the One True Faith™ and their god(s) were the One True God(s)™. In the western tradition, the Greek philosophers starting arguing for (and against) gods, well back before the Common Era.
Epicurus (341–270 BC) has attributed to him (it might, however, been part of a campaign to smear Epicurus as an atheist—theists apparently lie a lot) the argument: Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Then whence cometh evil? Is he neither able nor willing? Then why call him God?
Plato and Aristotle, amongst others, both made arguments for the existence of gods. So reason was being applied to faith thousands of years ago if the historical record is to be trusted.
Fast forward over much of the “Dark Ages” and we reach Saint Anselm (1033-1109 CE). Anselm became a Doctor of the Church and a Saint for using reason to support the case for the existence of his god. His go to argument was the ontological argument.
So, rather than there being an antagonism between reason and faith, as it seems is almost always the case now, reason was good if it supported religious faith, bad if it did not. This is much like Republicans being in favor of smaller government, except when it comes to war making, control over women’s bodies, doing favors for businesses and rich people, etc.
Religion was always suspicious of reason because reason required no intermediaries (especially their intermediaries). Reason could go on inside someone’s head and you wouldn’t even know it! This did not contribute to the elite’s control over society, so was looked upon with suspicion . . . except where the tame reasoners could be trotted out on their leashes.
It is the same today. Christian apologists make fair incomes by going around and applying reason to their faith and coming to the conclusions that: god exists, faith is good, atheism is bad, etc. Science is declared to be atheistic because it is based solely upon reason, but the apologists are holy men for doing the same.
