If we are to go forward, we must go back and rediscover those precious values — that all reality hinges on moral foundations and that all reality has spiritual control.

More from Martin Luther King Jr.

• A man dies when he refuses to stand up for that which is right. A man dies when he refuses to stand up for justice. A man dies when he refuses to take a stand for that which is true.
• Anyone who lives inside the United States can never be considered an outsider anywhere within its bounds.
• Everything that we see is a shadow cast by that which we do not see.
• Returning hate for hate multiplies hate, 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.
• Shallow understanding from people of good will is more frustrating than absolute misunderstanding from people of ill will. Lukewarm acceptance is much more bewildering than outright rejection.
• The quality, not the longevity, of one’s life is what is important. If you are cut down in a movement that is designed to save the soul of a nation, then no other death could be more redemptive.
