It is very difficult to pass from pleasure to work. Accordingly more poems have been swallowed up by sorrow than ever happiness caused to blaze forth in unparalleled radiance.
A poet, as he is the author to others of the highest wisdom, pleasure, virtue, and glory, so he ought personally to be the happiest, the best, the wisest, and the most illustrious of men.
What a poem means is as much what it means to others as what it means to the author; and indeed, in the course of time a poet may become merely reader in respect to his own works, forgetting his original meaning.
Poetry, even that of the loftiest, and seemingly, that of the wildest odes, [has] a logic of its own as severe as that of science; and more difficult, because more subtle, more complex, and dependent on more and more fugitive causes. In the truly great poets... there is a reason assignable, not only for every word, but for the position of every word.
Not only every great poet, but every genuine, but lesser poet, fulfils once for all some possibility of language, and so leaves one possibility less for his successors.
