Abstract

The essay begins by recalling the words of Homer that to live is to behold the light of the sun. For it is the ‘elementals’ of sky, sun, and light that give all things to mortal beings, including time itself, beginning with the daily alternation between day and night. But contemporary commercial and scientific projects threaten to change all this. Whether it be through the launching of tens of thousands of communication satellites to fill the night sky or the creation of a sulfuric blanket in the atmosphere to block the sun’s rays to combat global warming, what is threatened is our very relationship to the sun and to light. The essay thus argues that what is today needed is a new ‘politics of light’, one that would guard the clarity of the sky. Needed as well is a philosophy that attends to things beyond the human life-world, to the elementals of sun, sky, and light, but also to the invisibility at the heart of light itself. Appealing to some of the most recent scientific discoveries regarding the hyper-giganticness of the cosmos, the essay concludes that philosophy must attend to ‘phenomena’ whose nature is precisely to remain concealed, phenomena such as black holes, dark matter, and dark energy that are today thought to comprise an astonishing 95% of the matter and energy of the universe. Turned in this direction, the essay concludes, philosophy can perhaps reawaken the wonder that is at its very origin.
