Prejudice, Influence of
Fixed prejudices resist truth even when faced with clear evidence to the contrary.
A gentleman was one day stoutly asserting that there were no gold-fields except in Mexico and Peru. A nugget dug up in California was presented to him as evidence against his positive assertion. He was not in the least disconcerted. "This metal, sir, is, I own, extremely like gold; and you tell me that it passes as such in the market, having been declared by the assayers to be indistinguishable from the precious metal. All this I will not dispute. Nevertheless, the metal is not gold, but auruminium: it cannot be gold, because gold comes only from Mexico and Peru." In vain was he informed that the geological formation was similar in California and Peru, and the metals similar. He had fixed in his mind the conclusion that gold existed only in Mexico and Peru: this was a law of Nature. He had no reasons to give why it should be so; but such had been the admitted fact for many years, and from it he could not swerve. Lewes.
