'Where Do We Go From Here?" as published in Where Do We Go from Here : Chaos or Community? (1967), p. 62; many statements in this book, or slight variants of them, were also part of his address Where Do We Go From Here?" which has a section below. A common variant appearing at least as early as 1968 has "Returning violence for violence multiplies violence..." An early version of the speech as published in A Martin Luther King Treasury (1964), p. 173, has : "Returning hate for hate multiplies hate..."

Context: 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.

As translated in 1,001 Pearls of Wisdom (2006) by David Ross, p. 36
Context: Cling to truth and it turns into falsehood. Understand falsehood and it turns into truth. Truth and falsehood are two sides of the same coin. Neither accept one nor reject the other.

Aeschines, In Timarchum, 84 (107).

Context: Suffering is a sign that you're out of touch with the truth. Suffering is given to you that you might open your eyes to the truth, that you might understand that there's falsehood somewhere, just as physical pain is given to you so you will understand that there is disease or illness somewhere. Suffering points out that there is falsehood somewhere. Suffering occurs when you clash with reality. When your illusions clash with reality when your falsehoods clash with the truth, then you have suffering. Otherwise there is no suffering.
