Martin Luther King Jr.

"Injustice anywhere is a threat to justice everywhere."

"Our scientific power has outrun our spiritual power. We have guided missiles and misguided men."

"Nothing in all the world is more dangerous than sincere ignorance and conscientious stupidity."

"I believe that unarmed truth and unconditional love will have the final word in reality. That is why right, temporarily defeated, is stronger than evil triumphant."

"When you are right you cannot be too radical; when you are wrong, you cannot be too conservative."

"Like an unchecked cancer, hate corrodes the personality and eats away its vital unity. Hate destroys a man's sense of values and his objectivity. It causes him to describe the beautiful as ugly and the ugly as beautiful, and to confuse the true with the false and the false with the true."

- Martin Luther King Jr.
