The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.

When you have to cast movies from a producer's standpoint - when you've been on the other side of casting sessions - you just get a completely different perspective on what that process is of getting a job for an actor. You realize how completely impersonal it is. If anything, I think it's made me a lot less sensitive.

Unfortunately, I think that's one of the last things that gets factored in when you're assembling a cast.

Fear is the enemy of logic.

Some people will follow their minds without listening to their hearts, and others will follow their hearts without listening to their minds. This is why reason exists, for there to be balance between the heart and mind. We were not meant to follow the mind and ignore the heart.

Mystical experience of nature can be of particular relevance to our troubled age, bringing deeper into our consciousness and emotions the logic that nature sustains humanity as humanity must, in turn, sustain nature.

They express a preference for ‘natural’ methods of population limitation, and a natural method is exactly what they are going to get. It is called starvation.

I just saw Titanic, which is a $200 million film about a real-life disaster at sea, but according to Hollywood Logic, none of the actual passengers was interesting enough, so the writer-director had to invent a Romeo and Juliet-style fictional couple to heat up the catastrophe.
