Joseph Brodsky: 

“Poetry is not ‘the best words in the best order’; for language it is the highest form of existence. In purely technical terms, of course, poetry amounts to arranging words with the greatest specific gravity in the most effective and externally inevitable sequence. Ideally, however, it is language negating its own mass and the laws of gravity; it is language’s striving upward—or sideways—to that beginning where the Word was.” 

We are permitted to think of “that beginning where the Word was” in many different ways. That beginning does not belong only to beliefs figured in the beginning of the Tanakh, the Bible (at the beginning of the book of Genesis). “That beginning where the Word was” is the beginning of language use, and our use of language (as well as its use, with us, by Yahweh and other gods) is one event (as we imagine it) by which we may define the beginningness of a human way of being.
