“If ever we should find ourselves disposed not to admire those writers or artists, Livy and Virgil for instance, Raphael or Michael Angelo, whom all the learned had admired, [we ought] not to follow our own fancies, but to study them until we know how and what we ought to admire; and if we cannot arrive at this combination of admiration with knowledge, rather to believe that we are dull, than that the rest of the world has been imposed on.”
