There is no Accounting for this Attempt upon Mankind: The Doctor, I doubt not, has often made Trial, how far their good Nature could carry their Belief: but this obtruding on _Scholars_, and _Physicians_ too, is no less exposing Physick than Physicians. Such Credulity is the very Reverse of the Incredulity our _Saviour_ complains of, and no less Marvellous. It is indeed Marvellous, how People were Unbelievers after the greatest Evidence of Reason and Miracle: Yet we cannot forbear admiring, if People should swallow all this Trifle and Contradiction, against all Sense and Reason. We are, indeed, at a loss to explain this lazy Credulity; and therefore we must have Recourse to the general _Infection_, that has wrought so strong Delusion, of late Years, all over _Europe_; when we find Men have become wonderfully Credulous, even to _Infatuation_. Upon this Supposition a very tolerable good Account may be given of the mentioned Attempts, for fathoming the Credulity of Men, let that be found to be ever so deep. If we hove our Lead in the _South Sea_, we could sound to an hundred Fathom, and bring up yellow Sand upon the Lead. Some Doctors have often sounded fifty Fathom for yellow Sand; and Doctor _Anodyne Necklace_ almost as deep for the same. The _South Sea_ Pilots have now run us a-ground, notwithstanding the Depth of Water; and Men begin to recover their Senses by the _Surprize_, _Terriculamenta_ being often found useful to Children: And, I hope, now they are awake, they will never hereafter subject either their _Lives_ or _Fortunes_ to _Directors_ of any kind.
