To be uncertain is to be uncomfortable, but to be certain is to be ridiculous.
I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong.

Human science is an uncertain guess.
In this uncertain space between birth and death, especially here at the end of the world in Moonlight Bay, we need hope as surely as we need food and water, love and friendship.
