"The book that really, really shaped my politics and has forever is Arthur Koestler's "Darkness at Noon," which is a novel based on terrible fact about what it was like in Russia during Stalin's time when people actually believed that to get to the point where the Proletariat would triumph, anything that was necessary to be done should be done; the means didn't count."

You cannot see what I see because you see what you see. You cannot know what I know because you know what you know. What I see and what I know cannot be added to what you see and what you know because they are not of the same kind. Neither can it replace what you see and what you know, because that would be to replace you yourself." "Hang on, can I write this down?" said Arthur, excitedly fumbling in his pocket for a pencil.
