In an interview with the Guardian, Stephen Hawking dismissed the notion that humans have a soul, stating that "I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark."
In previous interviews, Hawking has also expressed skepticism about the existence of God. When asked by the Guardian how we are supposed to live if there is no God to provide us with guidance, Hawking gave a simple but I think brilliant answer. "We should" he said, "seek the greatest value of our action."
