At the same time, class struggles resulted in the rights and privileges civilized people take for granted. The same religions that caused so many wars and massacres inspired men to build places of worship of immeasurable beauty, and raise splendid hymns to the sky. Nationalism made scholars turn away from their books for a moment to discover, collect and record the ballads and gentle tunes that people had been creating and passing down for generations. I pity those who've never felt their blood boil for something. Perhaps they think they're happier this way, because they don't know what they're missing.
Ignorance is bliss.
Even our similarities with stray dogs have a limit. After seeing Trajan's Column I didn't buy a gun to shoot people whose beliefs differ from mine. We're people - hopefully, civilized people. It's the duty of civilized man not to let prejudice surface, not to let it influence his judgment. The mind must subdue the soul and keep us from repeating things like St. Bartholomew's Night, the Holocaust, or Communism.
