Love and Death, de Woody Allen (1975)
Sonja: Boris, Let me show you how absurd your position is. Let's say there is no God, and each man is free to do exactly as he chooses. What prevents you from murdering somebody?
Boris: Murder's immoral.
Sonja: Immorality is subjective.
Boris: Yes, but subjectivity is objective.
Sonja: Not in a rational scheme of perception.
Boris: Perception is irrational. It implies immanence.
Sonja: But judgment of any system or a priori relation of phenomena exists in any rational or metaphysical or at least epistemological contradiction to an abstracted empirical concept such as 'being' or 'to be' or 'to occur' in the thing itself or of the thing itself.
Boris: Yeah, I've said that many times.
