Martin Luther King on news that Al Qaeda Resumed Pre-9/11 Strength.

From his essay "Where Do We Go from Here?" published in A Testament of Hope: The Essential Writings of Martin Luther King, Jr. published by HarperCollins

Are we seeking power for power's sake? Or are we seeking to make the world and our nation better places to live. If we seek the latter, violence can never provide the answer. The ultimate weakness of violence is that it is a descending spiral, begetting the very thing it seeks to destroy. Instead of diminishing evil, it multiplies it. Through violence you may murder the liar, but you cannot murder the lie, nor establish the truth. Through violence you may murder the hater, but you do not murder hate. In fact, violence merely increases hate. So it goes. Returning violence for violence multiplies violence, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.
