Two notable Closer To Truth contributors—and two good friends—discuss their intellectual and spiritual journeys in what seems to be opposite directions: one toward a form of Christianity and the other away from it.   Philip Goff is a British author, idealist philosopher, and professor at Durham University whose research focuses on philosophy of mind and consciousness. Specifically, it focuses on how consciousness can be part of the scientific worldview. He is the author most recently of the book Why? The Purpose of the Universe.     Helen De Cruz is a Belgian philosopher and Danforth Chair of Philosophy at Saint Louis University who specializes in philosophy of religion, experimental philosophy, and philosophy of cognitive science. She is also an activist supporting the rights of EU citizens in the context of Brexit. Her most recent book is Wonderstruck: How Wonder and Awe Shape the Way We Think.
