Edmund Burke said this quote

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.
