But in the finished art of the song the use of words has no connection with the use of words in poetry.

For while the subjects of poetry are few and recurrent, the moods of man are infinitely various and unstable. It is the same in all arts.

If it is an imperfect word, no external circumstance can heighten its value as poetry.

It should here be added that poetry habitually takes the form of verse.

Poetry being the sign of that which all men desire, even though the desire be unconscious, intensity of life or completeness of experience, the universality of its appeal is a matter of course.
