Galileo is said to have muttered when he was forced to recant the heresy that the earth was not the center of an Aristotelian universe, “E pur si muove.” – “And yet, it moves.”

Muriel Rukeyser, in her essay “The Life of Poetry’ asks the reader, “What is our ‘E pur si muove?’”

This question is in the context of her conviction that poetry and science are similar processes, in which we seek to learn the true relations of things.  And in both cases, she believes that the answers come in the form of questions.

Science is not static; the universe is not static: poetry is not static.  Each moves. And the motion of a poem is motion in time, like music.  Science is not, properly speaking, a study of objects.  The poem is not words or images, which can be separated for study; it is a series of relationships between words and images.

These are a few of the stimulating ideas from Rukeyser’s “The Life of Poetry” first published in 1949 and reprinted in 1996.  By her title she suggests that poetry is living, organic.  Poems do something in the world.

The poet and the scientist are on parallel paths.  I think Rukeyser’s ideas are supported by some of the developments in science since she wrote; the poets may be having trouble keeping up.
