“Shannon: Only the living suffered. Only they were riddled with guilt and regret and unanswered questions.”

“I regret nothing. There have been things I missed, but I ask no questions, because I have loved it, such as it has been, even the moments of emptiness, even the unanswered-and that I loved it, that is the unanswered in my life.”

“Guilt and no guilt: these were the worst things. The only thing worse than the guilt was the fear of getting caught.”

“Life is an unanswered question, but let's still believe in the dignity and importance of the question.”

“Unbalanced power poisons introspection. In its vacated space lay living society's imperative questions, unseen, unphrased, unasked, unanswered.”

“For myself, I am interested in science and in philosophy only because I want to learn something about the riddle of the world in which we live, and the riddle of man's knowledge of that world. And I believe that only a revival of interest in these riddles can save the sciences and philosophy from an obscurantist faith in the expert's special skill and in his personal knowledge and authority.”
