“I have been driven many times upon my knees by the overwhelming conviction that I had nowhere else to go. My own wisdom and that of all about me seemed insufficient for that day.”
Noah Brooks, scribe for the Sacramento Union, writing in the Harper’s Weekly for July 1865, 3 months after Lincoln had died, reported that the Lincoln once said this, at an unspecified date; as reported in "Did Abraham Lincoln Actually Say That Obama Quote?" by James M. Cornelius, The Daily Beast (9 August 2012) http://www.thedailybeast.com/articles/2012/09/08/did-abraham-lincoln-actually-say-that-obama-quote.html

1960s, Beyond Vietnam: A Time to Break Silence (1967)
Context: Over the past two years, as I have moved to break the betrayal of my own silences and to speak from the burnings of my own heart, as I have called for radical departures from the destruction of Vietnam, many persons have questioned me about the wisdom of my path. At the heart of their concerns this query has often loomed large and loud: Why are you speaking about war, Dr. King? Why are you joining the voices of dissent? Peace and civil rights don't mix, they say. Aren't you hurting the cause of your people, they ask? And when I hear them, though I often understand the source of their concern, I am nevertheless greatly saddened, for such questions mean that the inquirers have not really known me, my commitment or my calling. Indeed, their questions suggest that they do not know the world in which they live.

Peoples Archive interview
Context: The word fractal, once introduced, had an extraordinary integrating effect upon myself and upon many people around. Initially again it was simply a word to write a book about, but once a word exists one begins to try to define it, even though initially it was simply something very subjective and indicating my field. Now the main property of all fractals, put in very loose terms, is that each part — they're made of parts — each part is like the whole except it is smaller. After having coined this word I sorted my own research over a very long period of time and I realised that I had been doing almost nothing else in my life.
