“...supernatural explanations always mean the end of inquiry: that’s the way God wants it, end of story. Science, on the other hand, is never satisfied: our studies of the universe will continue until humans go extinct.”

“Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end.”

“But the nature of the universe is such that the ends never justify the means. On the contrary, the means always determine the end.”

“There really is only one ending to any story. Human life ends in death. Until then, it keeps going and gets complicated and there's loss. Everything involves loss; every relationship ends in one way or another.”

“There was a terminal narrative. It was a story until it stopped being a story and until then they kept wanting to know. Give up... Surrender your need for the detail; there is only one way this is going to end.”

“Human beings are never to be treated as a means but always as ends.”
