Contempt Prior to Examination is an Intellectual Vice

William Paley on how intellectuals can be biased against evidence:

Contempt prior to examination is an intellectual vice from which the greatest faculties of mind are not free. I know not indeed whether men of the greatest faculties of mind are not the subject to it. Such men feel themselves seated upon an eminence. Looking down from their height upon the follies of mankind, they behold contending tenets wasting their idle strength upon one another, with the common disdain of the absurdity of them all. This habit of thought, however comfortable to the mind which entertains it, or however natural to great parts, is extremely dangerous; and more apt, than almost any other disposition, to produce hasty and contemptuous, and, by consequence, erroneous judgments both of persons and opinions.
