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 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.
~Where Do We Go From Here: Chaos or Community? (1967)
The tough mind is sharp and penetrating, breaking through the crust of legends and myths and sifting the true from the false. The tough-minded individual is astute and discerning. He has a strong austere quality that makes for firmness of purpose and solidness of commitment.Who doubts that this toughness is one of man's greatest needs? Rarely do we find men who willingly engage in hard, solid thinking. There is an almost universal quest for easy answers and half-baked solutions. Nothing pains some people more than having to think.
~Strength to Love (1963)
One has not only a legal, but a moral responsibility to obey just laws. Conversely, one has a moral responsibility to disobey unjust laws.
Injustice anywhere is a threat to justice everywhere.~Letters From a Birmingham Jail (1963)
