Long ago, let’s say in the Garden of Eden, rationality and irrationality were one. Some people may still sojourn in this blissful state but now the two categories are generally considered separate and even mutually exclusive. The reason for this separation is that people have begun to acknowledge different truths. Besides stupidity, selfishness and local living conditions the abstract reasoning is the chief culprit for the discrepancy of truths. Faiths perpetually erect towers of Babel from which people try to outshout their neighbours. This is how God must have brought multiple languages into existence.
