I found those quotations very relevant to ongoing events:
"The worst sin toward our fellow creatures is not to hate them, but to be indifferent to them: that’s the essence of inhumanity."
George Bernard Shaw, "The Devil’s Disciple"
"Fool me once, shame on you. Fool me twice, shame on me !" Author Unknown
- “Failure is only an opportunity to begin more intelligently.” -Henry Ford
