By Mahatma Gandhi:

• politics without principle
• wealth without work
• commerce without morality
• pleasure without conscience
• education without character
• science without humanity
• worship without sacrifice

By W.H. Auden:

"I and the public know
What all schoolchildren learn,
Those to whom evil is done
Do evil in return."

Next time there's riots, don't forget: Gandhi warned you. Auden warned you. No excuses.
