When corrected, the passage given above would read as follows--
ANTIQUITY, like every other quality that attracts the notice of mankind, has undoubtedly votaries that _reverence_ it, not from reason, but from prejudice. Some seem to admire indiscriminately whatever has been long preserved, without considering that time has sometimes co-operated with chance: all perhaps are more willing to honour past than present excellence; and the mind contemplates genius through the shades of age, as the eye surveys the sun through artificial opacity. The great contention of criticism is to find the faults of the moderns and the beauties of the ancients. While an author is yet living, we estimate his powers by his worst performances; and when he is dead, we rate them by his best.
To works, however, of which the excellence is not absolute and definite, but gradual and comparative; to works, not raised upon principles demonstrative and scientific, but appealing wholly to observation and experience, no other test can be applied than LENGTH of duration and continuance of esteem.
