That a
Poem shall be worthy of the writer's genius,--that it shall reach a
perfection commensurate with its aim,--that we should require finish in
proportion to brevity,--that passion, colour, and originality cannot
atone for serious imperfections in clearness, unity, or truth,--that a
few good lines do not make a good poem,--that popular estimate is
serviceable as a           more than as a compass,--above all, that
Excellence should be looked for rather in the Whole than in the
Parts,--such and other such canons have been always steadily regarded.
