ignorance, and who would warn the weasel to keep awake. How should a small-eyed, feebly crowing mortal like him be quicker in arithmetic than the keen-faced forcible Aquila, in whom universal knowledge is easily credible? Looked into closely, the conclusion from a man's profile, voice, and fluency to his certainty in multiplication beyond the twelves, seems to show a confused notion of the way in which very common things are connected; but it is on such false correlations that men found half their inferences about each other, and high places of trust may sometimes be held on no better foundation. It is a commonplace that words, writings, measures, and performances in general, have qualities assigned them not by a direct judgment on the performances themselves, but by a presumption of what they are likely to be, considering who is the performer. We all notice in our neighbours this reference to names as guides in criticism, and all furnish illustrations of it in our own practice; for, check ourselves as we will, the first impression from any sort of work must depend on a previous attitude of mind, and this will constantly be determined by the influences of a name. But that our prior confidence or want of confidence in given names is made up of judgments just as hollow as the consequent praise or blame they are taken to warrant, is less commonly perceived, though there is a conspicuous indication of it in the surprise or disappointment often manifested in the disclosure of an authorship about which everybody has been making wrong guesses. No doubt if it had been discovered who wrote the 'Vestiges,' many an ingenious structure of probabilities would have been spoiled, and some disgust might have been felt for a real author who made comparatively so shabby an appearance of likelihood. It is this foolish trust in prepossessions, founded on spurious evidence, which makes a medium of encouragement for those who, happening to have the ear of the public, give other people's ideas the advantage of appearing under their own well-received name, while any remonstrance from the real producer becomes an unwelcome disturbance of complacency with each person who has paid complimentary tributes in the wrong place.
