of legerdemain, were determined to riot luxuriously on the ignorance and credulity of mankind._ CHAP. VIII. _Examination of the Advantages which result from Man's Notions on the Divinity.--Of their Influence upon Mortals;--upon Politics;--upon Science;--upon the Happiness of Nations, and that of Individuals._ The slender foundation of those ideas which men form to themselves of their gods, must have appeared obvious in what has preceded; the proofs which have been offered in support of the existence of immaterial substances, have been examined; the want of harmony that exists in the opinions upon this subject, which all concur in agreeing to be equally impossible to be known to the inhabitants of the earth, has been shewn; the incompatibility of the attributes with which, theology has clothed incorporeity, has been explained. It has been proved, that the idols which man sets up for adoration, have usually had their birth, either in the bosom of misfortune, when ignorance was at a loss to account for the calamities of the earth upon natural principles, or else have been the shapeless fruit of melancholy, working upon an alarmed mind, coupled with enthusiasm and an unbridled imagination. It has been pointed out how these prejudices, transmitted by tradition from father to son, grafting themselves upon infant minds, cultivated by education, nourished by fear, corroborated by habit, have been maintained by authority; perpetuated by example. In short, every thing must have distinctly evidenced to us, that the ideas of the gods, so generally diffused over the earth, has been little more than an universal delusion of the human race. It remains now to examine if this error has been useful.
