Imposture Quotes
Among the sayings and discourses imputed to him [Jesus] by his biographers, I find many passages of fine imagination, correct morality, and of the most lovely benevolence; and others again of so much ignorance, so much absurdity, so much untruth, charlatanism, and imposture, as to pronounce it impossible that such contradictions should have proceeded from the same being. I separate, therefore, the gold from the dross; restore to Him the former, and leave the latter to the stupidity of some, and roguery of others of His disciples.

And because this Experimental Science is wholly ignored by the general run of students, for that reason I can not convince people of its utility unless I show at the same time its excellence and its property. This science alone, then, knows how to test perfectly by experience what can be done by nature, what by the industry of art, what by imposture; what the incantations, conjurations, invocations, deprecations, sacrifices (which are magical devices) seek and dream of; and what is done in them, so that all falsity may be removed and that only the truth of art and nature be retained. This science alone teaches one to consider all the insanities of magicians, not that they may be confirmed but that they may be avoided, just as logic considers sophistical argument.

SPIRITUAL WIFE DOCTRINE. IMPOSTURE. THE DOCTRINE IS FALSE. MONEY DIGGER. FALSE PROPHET. DELUSION. SPIRITUAL WIFE DOCTRINE. Oh, my dear brethren and sisters, keep away from them, for the sake of your never dying souls. FALSE PROPHETS THAT SHOULD COME IN THE LAST DAYS. OLD JOE SMITH. ANTI-CHRIST. MONEY DIGGER, MONEY DIGGER, MONEY DIGGER. And the whole is wound up with an appeal, not to the good sense of the people, but to their unnatural feelings, in a canting, hypocritical tone, and there it ends.
