Among our small collection of the Papers of Aldous Huxley, is a heavily annotated, undated, draft of an introduction that Huxley once gave for Edna St. Vincent Millay. The draft shows Huxley's struggles to get the tone just right--making small changes like substituting "impetuous current" for "onrush" and revamping entire sentences then rejecting them altogether. His final version captures the force of Milley's poetry and then summons her to the stage:
Like the Elizabethans, she seems constantly on the verge of being swept off her feet by the impetuous current of her own eloquence; but just as it seems inevitable that she should fall, the headlong movement is miraculously transformed before your eyes into a figure of the Dance, into some beautiful gesture, entirely unexpected and novel, and entirely satisfying.
The same could be said for Huxley's introduction--a beautiful work in itself. Come read it and see all of his changes by asking for MS 268, Box 1.
