“I began taking liberties a long time ago; now it is standard practice for most directors to ignore the rules.”

Context: It's already getting more and more difficult to make an ambitious and original film. There are less and less independent producers or independent companies and an increasing number of corporations who are more interested in balance sheets than in artistic achievement. They want to make a killing each time they produce a film. They're only interested in the lowest common denominator because they're trying to reach the widest audience. And you got some kind of entropy. That's the danger; they look more alike, those films. The style is all melting and it all looks the same. Even young directors — for most of them, their only standard of achievement is how well their films do on the first weekend or whatever. It worries me. But then, from time to time, you have a film like The Usual Suspects or.... I'm trying to think of something American with some kind of originality... Pulp Fiction.

Context: There is no logical impossibility in the hypothesis that the world sprang into being five minutes ago, exactly as it then was, with a population that "remembered" a wholly unreal past. There is no logically necessary connection between events at different times; therefore nothing that is happening now or will happen in the future can disprove the hypothesis that the world began five minutes ago.

Context: I made up my mind long ago to follow one cardinal rule in all my writing — to be clear. I have given up all thought of writing poetically or symbolically or experimentally, or in any of the other modes that might (if I were good enough) get me a Pulitzer prize. I would write merely clearly and in this way establish a warm relationship between myself and my readers, and the professional critics — Well, they can do whatever they wish.
