Thanks to the first mode of consciousness, every good poem is unique; thanks to the second, a poet can embody his private experiences in a public poem which can be comprehended by others in terms of their private experiences; thanks to the third, both poet and reader desire that this be done.
The subject matter of the scientist is a crowd of natural events at all times; he presupposes that this crowd is not real but apparent, and seeks to discover the true place of events in the system of nature. The subject matter of the poet is a crowd of historical occasions of feeling recollected from the past; he presupposes that this crowd is real but should not be, and seeks to transform it into a community. Both science and art are primarily spiritual activities, whatever practical applications may be derived from their results. Disorder, lack of meaning, are spiritual not physical discomforts, order and sense spiritual not physical satisfactions.
It is impossible, I believe, for any poet, while he is writing a poem, to observe with complete accuracy what is going on, to define with any certainty how much of the final result is due to subconscious activity over which he has no control, and how much is due to conscious artifice. All one can say with certainty is negative. A poem does not compose itself in the poet's mind as a child grows in its mother's womb;
The subject matter of a poem is comprised of a crowd of recollected occasions of feeling, among which the most important are recollections of encounters with sacred beings or events. This crowd the poet attempts to transform into a community by embodying it in a verbal society. Such a society, like any society in nature, has its own laws; its laws of prosody and syntax are analogous to the laws of physics and chemistry. Every poem must presuppose—sometimes mistakenly—that the history of the language is at an end.
One should say, rather, that a poem is a natural organism, not an inorganic thing. For example, it is rhythmical. The temporal recurrences of rhythm are never identical, as the metrical notation would seem to suggest. Rhythm is to time what symmetry is to space. Seen from a certain distance, the features of a human face seem symmetrically arranged, so that a face with a nose a foot long or a left eye situated two inches away from the nose would appear monstrous. Close up, however, the exact symmetry disappears; the size and position of the features vary slightly from face to face and, indeed, if a face could exist in which the symmetry were mathematically perfect, it would look, not like a face, but like a lifeless mask. So with rhythm. A poem may be described as being written in iambic pentameters, but if every foot in every line were identical, the poem would sound intolerable to the ear. I am sometimes inclined to think that the aversion of many modern poets and their readers to formal verse may be due to their association of regular repetition and formal restrictions with all that is most boring and lifeless in modern life, road drills, time-clock punching, bureaucratic regulations.
It has been said that a poem should not mean but be. This is not quite accurate. In a poem, as distinct from many other kinds of verbal societies, meaning and being are identical. A poem might be called a pseudo-person. Like a person, it is unique and addresses the reader personally. On the other hand, like a natural being and unlike a historical person, it cannot lie. We may be and frequendy are mistaken as to the meaning or the value of a poem, but the cause of our mistake lies in our own ignorance or self-deception, not in the poem itself.
