Nathan: You know this guy, right?
Caleb: Jackson Pollock.
Nathan: Jackson Pollock. That's right. The drip painter. Okay. He let his mind go blank, and his hand go where it wanted. Not deliberate, not random. Some place in between. They called it automatic art. Let's make this like Star Trek, okay? Engage intellect.
Caleb: Excuse me?
Nathan: I'm Kirk. Your head's the warp drive. Engage intellect. What if Pollock had reversed the challenge. What if instead of making art without thinking, he said, "You know what? I can't paint anything, unless I know exactly why I'm doing it." What would have happened?
Caleb: He never would have made a single mark.
