'Cleveralities'

A wise man who had great influence on me in my youth concocted the word'cleveralities' to describe the pseudo-science or apparent cleverness sometimes employed to cover foolishness or self-indulgence. Sometimes we can even blind ourselves with such false reasoning which is why many clever people are also extremely foolish, convinced that even black is white.We may know people like that and even have caught sight of them in the mirror.
