I. The Superphysical World and Its Gnosis

“A seasoned African explorer would care but little for the criticisms passed on his report by persons who had never been thither; he might tell what he saw, describe the animals whose habits he had studied, sketched the country he had traversed, sum up its products and its characteristics. If he was contradicted, laughed at, set right, by untravelled critics, he would be neither ruffled nor distressed, but would merely leave them alone. Ignorance cannot convince knowledge by repeated asseveration of its nescience. The opinion of a hundred persons on a subject of which they are wholly ignorant is of no more weight than the opinion of one such person. Evidence is strengthened by many consenting witnesses, testifying each to his knowledge of a fact, but nothing multiplied a thousand times remains nothing.”
