Every revealed religion is filled with mysterious dogmas, unintelligible principles, incredible wonders, astonishing recitals, which appear to have been invented solely to confound reason. Every religion announces a hidden God, whose essence is a mystery; consequently, the conduct, ascribed to him, is no less inconceivable than his essence. The Deity has never spoken only in an enigmatical and mysterious manner, in the various religions, which have been founded in different regions of our globe; he has everywhere revealed himself only to announce mysteries; that is, to inform mortals, that he intended they should believe contradictions, impossibilities, and things to which they were incapable of affixing any clear ideas.

The more mysterious and incredible a religion is, the more power it has to please the imagination of men. The darker a religion is, the more it appears divine, that is, conformable to the nature of a hidden being, of whom they have no ideas. Ignorance prefers the unknown, the hidden, the fabulous, the marvellous, the incredible, or even the terrible, to what is clear, simple, and true. Truth does not operate upon the imagination in so lively a manner as fiction, which, in other respects, everyone is able to arrange in his own way. The vulgar like to listen to fables. Priests and legislators, by inventing religions and forging mysteries have served the vulgar people well. They have thereby gained enthusiasts, women and fools. Beings of this stamp are easily satisfied with things, which they are incapable of examining. The love of simplicity and truth is to be found only among the few, whose imagination is regulated by study and reflection.

The inhabitants of a village are never better pleased with their parson, than when he introduces Latin into his sermon. The ignorant always imagine, that he, who speaks to them of things they do not understand, is a learned man. Such is the true principle of the credulity of the people, and of the authority of those, who pretend to guide nations.
