From Apocalypse Now, "Do you know what the man is saying? Do you? This is dialectics. It's very simple dialectics. One through nine, no maybes, no supposes, no fractions -- you can't travel in space, you can't go out into space, you know, without, like, you know, with fractions -- what are you going to land on, one quarter, three-eighths -- what are you going to do when you go from here to Venus or something -- that's dialectic physics, OK? Dialectic logic is there's only love and hate, you either love somebody or you hate them."
In this movie it has to do with truth. Dialectic logic is there's only truth and lies, you either believe somebody or you don't believe them."
