What does Captain Beatty say is a result of conflict?

Beatty says that the result of conflict is unhappiness.

Beatty got up. "I must be going. Lecture's over. I hope I've clarified things. The important thing for you to remember, Montag, is we're the Happiness Boys, the Dixie Duo, you and I and the others. We stand against the small tide of those who want to make everyone unhappy with conflicting theory and thought. We have our fingers in the dyke. Hold steady. Don't let the torrent of melancholy and drear philosophy drown our world.
