More quotes by Martin Luther King, Jr.

"Every man lives in two realms: the internal and the external. The internal is that realm of spiritual ends expressed in art, literature, morals, and religion. The external is that complex of devices, techniques, mechanisms, and instrumentalities by means of which we live."
"The quality, not the longevity, of one's life is what is important."
"At the center of non-violence stands the principle of love."
"Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that."
"I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality... I believe that unarmed truth and unconditional love will have the final word."
