So we have no idea what happens after we die, and I’ve taken that lack of our knowledge as an opportunity to write fiction about it. I have a book called Sum: Forty Tales from the Afterlives, and the idea is to shine a flashlight around the 'possibly' space to illustrate how interesting is the vastness of our ignorance.
Because what I see happening sometimes is there are people who have, let’s say, fundamentalist religious beliefs who believe one thing, and then, on the other hand, you’ve got neo-atheists who are acting very certain about their position. And the fact is we just don't know. We don't know enough to pretend like we’ve got it all figured out. We would need to know a lot more than we do to act as though we have certainty about what's not going on.
So this all led me to start a movement called possibilianism, which has now spread worldwide, I’m happy to say, and essentially represents a third voice. This voice I think is the voice of the scientific temperament, which is one of having multiple possibilities and being creative in generating the possibilities and being okay with uncertainty and having lots of hypotheses on the table.
