The Divorce of Lady X (1938)
Leslie: You're much too nice to turn me out.
Logan: Nice! My dear young lady, you don't know me. The trouble with me is that I'm weak. A charming young girl like you can put anything over on me in five minutes. But at least I know my weakness, so I force myself to be rude. Sometimes even brutal!
[Leslie starts backing Logan into a corner]
Leslie: You do like talking about yourself, don't you?
Logan: Why... yes... most men do. But at least they know the truth about themselves. Women don't. They only know the truth about each other.
Logan: Modern woman has no loyalty, decency, or justice; no endurance, reticence, or self-control; no affection, fine feelings, or mercy. In short, she is unprincipled, relentless, and exacting; idle, unproductive, and tedious; unimaginative, humorless, and vain; vindictive, undignified, and weak. And the sooner man takes out his whip again, the better for sanity and progress.
Logan: Because of my profession I happen to be able to know what lies behind those dear deceiving lips...
Leslie: Oh - you're a dentist?
Logan: No! I'm a barrister!
Logan: We have ample opportunities in this court for learning what women mean, or what they mean they mean if in these days they mean anything at all.
