“The moment a mind closes is the moment it can no longer evolve. Intellectual inertia soon follows. I suppose that in many ways this is one of my main objections to theism; it assumes that all questions are already firmly answered. There is no room for curiosity. A closed question does not lead to other questions. Thus, there is no progression, no evolution, no molting. This is no good for me. I want to evolve. I want to progress. I want to molt. And I want to keep learning about the real mysteries of this Universe.”
