More safely truth to urge her claim presumes,

There are few books on which more time is spent by young students, than on treatises which deliver the characters of authors; nor any which oftener deceive the expectation of the reader, or fill his mind with more opinions which the progress of his studies and the increase of his knowledge oblige him to resign.
Baillet has introduced his collection of the decisions of the learned, by an enumeration of the prejudices which mislead the critick, and raise the passions in rebellion against the judgment. His catalogue, though large, is imperfect; and who can hope to complete it? The beauties of writing have been observed to be often such as cannot in the present state of human knowledge be evinced by evidence, or drawn out into demonstrations; they are therefore wholly subject to the imagination, and do not force their effects upon a mind pre-occupied by unfavourable sentiments, nor overcome the counteraction of a false principle or of stubborn partiality.
To convince any man against his will is hard, but to please him against his will is justly pronounced by Dryden to be above the reach of human abilities. Interest and passion will hold out long against the closest siege of diagrams and syllogisms, but they are absolutely impregnable to imagery and sentiment; and will for ever bid defiance to the most powerful strains of Virgil or Homer, though they may give way in time to the batteries of Euclid or Archimedes.
In trusting therefore to the sentence of a critick, we are in danger not only from that vanity which exalts writers too often to the dignity of teaching what they are yet to learn, from that negligence which sometimes steals upon the most vigilant caution, and that fallibility to which the condition of nature has subjected every human understanding; but from a thousand extrinsick and accidental causes, from every thing which can excite kindness or malevolence, veneration or contempt.
