I think about my editor when I write. She's a good friend, too.

Throughout the entire history of philosophy, philosophers have sought to discover what man is - or what human nature is. But Sartre believed that man has no such eternal nature to fall back on. It is therefore useless to search for the meaning of life in general. We are condemned to improvise. We are like actors dragged onto the stage without having learned our lines, with no script and no prompter to whisper stage directions to us. We must decide for ourselves how to live.

I have gone around observing your activities from the outside. Because of this I have also been able to see things to which you have been blind... Every morning you have gone to work, but you have never been fully awake. Of course, you have seen the sun and the moon, the stars in the sky, and everything that moves, but you haven't really seen it at all. It is different for the Joker, because he was put into this world with a flaw: He sees too clearly and too much.

There are five billion people living on this planet. But you fall in love with one particular person, and you won't swap her for any other.

The truth is that I feel totally helpless, or totally inconsolable, to be more honest. I’m not trying to hide it, but it’s something you’re not to worry about.

The only thing we require to be good philosophers is the faculty of wonder.

I sat thinking how terribly sad it was that people are made in such a way that they get used to something as incredible as living. One day we suddenly take the fact that we exist for granted - and then, yes, then we don’t think about it anymore until we are about to leave the world again.
