Summary: We naturally talk about seeking the light at the end of the tunnel, or hoping to be enlightened. But are such phrases that reference light more than metaphors? In this episode of the Sheldrake-Vernon Dialogues, Rupert Sheldrake and Mark Vernon explore how light is both physical and spiritual, and note the remarkable harmony between scientific and mythical ways of exploring light. They ask about the links between light and intelligence, as discussed by figures from Plato to Dante, as well as how our inner lives, say when we dream, include light. Rupert reflects on his time in the ashram of Bede Griffiths, and Mark recalls remarks made by Roger Penrose. It turns out that the way we talk about the experience of light is hugely suggestive of the nature of reality. There are good reasons light is so closely associated with the divine.
