Nietzsche's Eternal Recurrence
What if, instead of the starchild representing some new transformation of Dave and humanity, Kubrick is going for something cyclical instead.
One of the themes in The Shining seems to involve how mankind forgets the atrocities of the past and as such is doomed to repeat them. What if Kubrick is also giving play to a similar idea in 2001? Maybe Dave doesn't defeat Hal, but they both end up killing each other in what is, simply put, another cycle in the seemingly endless washing machine of life on planet earth.
Consider this passage from Nietzsche's "Notes on the Eternal Recurrence":
"Whoever thou mayest be, beloved stranger, whom I meet here for the first time, avail thyself of this happy hour and of the stillness around us, and above us, and let me tell thee something of the thought which has suddenly risen before me like a star which would fain shed down its rays upon thee and every one, as befits the nature of light. - Fellow man! Your whole life, like a sandglass, will always be reversed and will ever run out again, - a long minute of time will elapse until all those conditions out of which you were evolved return in the wheel of the cosmic process. And then you will find every pain and every pleasure, every friend and every enemy, every hope and every error, every blade of grass and every ray of sunshine once more, and the whole fabric of things which make up your life. This ring in which you are but a grain will glitter afresh forever. And in every one of these cycles of human life there will be one hour where, for the first time one man, and then many, will perceive the mighty thought of the eternal recurrence of all things:- and for mankind this is always the hour of Noon".share
