Iain McGilchrist is the author of several books, most recently The Master and His Emissary.

What if we are not born with fully formed eternal souls, but must each grow our own in time? What if psyche, like physis, is a relational process, and not an independent substance?

McGilchrist quotes James Hillman: “The soul is not an object, but a way of knowing objects.”

McGilchrist wants to resurrect Plato’s theory of vision, where physical light comes into the eyes while spiritual light goes out of it.
