been inspired with by evil spirits. I would not be thought to go too far in a point of this nature, and have, therefore, though perhaps I could say much more if I followed entirely my own private opinion, and would venture to introduce it here, in order to communicate it to others, and make it a public one, said no more on this head than what divines generally teach. But the most unexceptionable mistress, that teaches these things to be in nature, is experience. If we had very many people gifted this way, the extraordinary thing would have been become ordinary, and therefore I cannot help wondering that it should be so ordinary a thing for wise men themselves to wonder too much at things because they are extraordinary, and suspect them as frauds because they are uncommon. There has scarce been any period of time in which some person of this prophetic class has not existed, and has not been consulted by the greatest of men, and their predictions found at the long run to come true; ignorant men always rise to their belief of them by experience, and the most learned men submit their great opinions to experience, but your men of middling talents, who make up their want of reason with bustling obstinacy and noisy contradiction, have been and still continue to be their own opposers, and without discovering the reason for what they say, they content themselves with having the laugh on their sides, and barely affirming without proving, that it is a kind of ideal juggle and intellectual legerdemain, by which these modern predictors impose things upon the eye of reason, as the corporeal eye is imposed upon by sleight of hand; but it is a strange thing that men of such quick reason cannot give us a sample of the frauds. Thus, I remember to have read, I cannot tell where, the story of some courtiers, who, when a great artist of legerdemain was to act before the King, pretended to be so quick-sighted, that nothing he did should escape their discovery, were left by his nimble fingers in the dark, and forced at last with blushes to own they had no better eyes than other people. In a word, if people will be led by suspicions and remote possibilities of fraud and contrivance of such men, all historical truth shall be ended, when it consists not with a man's private humour or prejudice to admit it. Now, therefore, to prove by experience and undeniable testimonies, that these kind of genii will submit to little offices, in order to bring men to greater good, I will give three or four curious passages that will set the reasonable reader at ease, and prepare him for reading the passages of Mr. Campbell's life with pleasure, and as a fine history of wonderful facts, that, though they seem to surpass belief, yet ought to have his credit.
