Quotes About Logic

I watched as Humphrey Bogart’s character used beans as a metaphor for the relative unimportance in the wider world of his relationship with Ingrid Bergman’s character, and chose logic and decency ahead of his selfish emotional desires. The quandary and resulting decision made for an engrossing film. But this was not what people cried about. They were in love and could not be together.

I love the psychology versus math and logic. In algebra, "X" means any possible variable. I sort of think about "X" in terms of the equation of my own life. Adding "X" to my own life has given me a freedom that I didn't have before in the equation of my own existence.

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.

To me, photography is the simultaneous recognition, in a fraction of a second, of the significance of an event as well as of a precise organization of forms which give that event its proper expression.

God wants us to give charity because it's the right thing to do.
