of genius, nothing can be stiled excellent till it has been compared
with other works of the same kind. Demonstration immediately
displays its power, and has nothing to hope or fear from the flux
of years; but works tentative and experimental must be estimated
by their proportion to the general and collective ability of man,
as it is discovered in a long succession of endeavours. Of the first
building that was raised, it might be with certainty determined
that it was round or square, but whether it was spacious or lofty
must have been referred to time. The Pythagorean scale of numbers
was at once discovered to be perfect; but the poems of Homer we
yet know not to transcend the common limits of human intelligence,
but by remarking, that nation after nation, and century after century,
has been able to do little more than transpose his incidents, new
name his characters, and paraphrase his sentiments.

The reverence due to writings that have long subsisted arises
therefore not from any credulous confidence in the superior wisdom
of past ages, or gloomy persuasion of the degeneracy of mankind,
but is the consequence of acknowledged and indubitable positions,
that what has been longest known has been most considered, and what
is most considered is best understood.

The Poet, of whose works I have undertaken the revision, may now
begin to assume the dignity of an ancient, and claim the privilege
of established fame and prescriptive veneration. He has long outlived
his century, the term commonly fixed as the test of literary merit.
Whatever advantages he might once derive from personal allusions,
local customs, or temporary opinions, have for many years been
lost; and every topick of merriment or motive of sorrow, which the
modes of artificial life afforded him, now only obscure the scenes
