“Ignorance is the mother of Devotion: A maxim that is proverbial, and confirmed by general experience. Look out for a people, entirely destitute of religion: If you find them at all, be assured, that they are but few degrees removed from brutes. What so pure as some of the morals, included in some theological system? What so corrupt as some of the practices, to which these systems give rise?”

Context: In the long run my observations have convinced me that some men, reasoning preposterously, first establish some conclusion in their minds which, either because of its being their own or because of their having received it from some person who has their entire confidence, impresses them so deeply that one finds it impossible ever to get it out of their heads. Such arguments in support of their fixed idea as they hit upon themselves or hear set forth by others, no matter how simple and stupid these may be, gain their instant acceptance and applause.
