or less pervaded with artificiality. The final judgment as to the nature of poetry resides in the appeal to the emotions. The test of poetry is not in the form which the writer uses, or in compliance with rules of prosody, but in the soul of the reader or hearer. If two emotional passages, one in a set pattern and one in prose have the same effect upon the responsive mechanism of the human soul, if they both arouse ecstasy, it matters not if you refuse to call the prose passage poetry; its effect is however that of poetry. It stirs and moves you to rapture, it is a product of the author's unconscious, it speaks from soul to soul, it is beautiful in its expressiveness, it has a rhythm of its own. I shall not be concerned if you refuse to call this emotional prose passage poetry, but it does belong to the literature of ecstasy, and ecstasy was and is the first condition of poetic composition. The poetry in verse is but part of the literature of ecstasy. I shall hence deal in this volume largely with emotional or impassioned prose; for it belongs to the literature of ecstasy, although it is often termed poetic prose, or sometimes disparagingly, prose poetry. Under this term I shall include not only the so-called "fine writing" but emotional passages in the language of the average man, dialogues from prose dramas, novels and short stories, and I shall also regard criticism, essays and works on science and philosophy highly charged with feeling as part of the province of the literature of ecstasy. This work becomes thus a treatise on poetics, and will present a new definition of poetry which will include all emotional prose writing. A very important phase of the subject will take in the connection between poetry or the literature of ecstasy, and various spheres of human thought, such as ethical and social questions. The idea will be shown to be an important factor in the literature of ecstasy, for ecstasy does not preclude the intellectual and moral activities. The notion of art for art's sake thus assumes a rather trivial aspect. Any idea whether scientific or philosophic, moral or social, if ecstatically presented, becomes itself literature of ecstasy, or poetry.Should the reader conclude to accept the prose literature of ecstasy as poetry, he will find there was much poetry in the world's prose literature that he has never recognized as such. He will also be compelled to admit that much of what has been called poetry, because written in verse, does not properly belong to poetry, as not being of the literature of ecstasy. He will also see that the artificial classifications of the different kinds of poetry,
