Ann Druyan, writer and executive producer of Cosmos: A Spacetime Odyssey, in a recent interview:

I have no problem asking the unanswerable questions, or in asking the as-yet-unanswerable questions. I have no problem with asking them, and I certainly have no issue with how we get through those dark nights of the soul by answering them. I would never presume to tell anyone how to answer them for themselves, not even my own children. I wouldn’t even think of it. I can only speak for myself when I say, “Yeah, asking questions – the more the better.” It’s just that if you come up with answers that make no adjustment to the scale of space and time that we find ourselves in, we see a failure of the imagination.

 
I happen to be surprisingly okay with uncertainty, but I’m not interested in intentionally rocking the world of someone who is not. All of our fellow humans are on their own, unique journey and traveling, presumably, as excellently as they think they can.

Keep asking questions and don’t settle for easy answers or answers that happen to work for someone else and have been handed to you in a tidy package. And have the courage to move on from the comfort of answers that were once cherished, or even sacred, but now don’t hold up to reason and have no compelling evidence to sustain them. The boat that got me across the river is no longer useful to me as I try to cross the mountain now in front of me. It’s okay to put the boat down and keep going.
