Here are some quotes from Martin Luther King Jr. These words are as relevant today as they were when he first said them:

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

Man must evolve for all human conflict a method which rejects revenge, aggression and retaliation. The foundation of such a method is love.

Our lives begin to end the day we become silent about things that matter.

Returning violence for violence multiplies violence, adding deeper darkness to a night already devoid of stars... Hate cannot drive out hate: only love can do that.

We must learn to live together as brothers or perish together as fools.

The hope of a secure and livable world lies with disciplined nonconformists who are dedicated to justice, peace and brotherhood.

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.
-Martin Luther King Jr.

Where is today's MLK Jr.? Who will break the silence?
