Here are some great quotes by Martin Luther King Jr:

“All men are caught in an inescapable network of mutuality.”

“In the end, we will remember not the words of our enemies, but the silence of our friends.”

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

“All progress is precarious, and the solution of one problem brings us face to face with another problem.”

“Injustice anywhere is a threat to justice everywhere.”

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

“The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy.”

“If your actions inspire others to dream more, learn more, do more and become more, you are a leader.”

“The time is always right to do what is right.”
