From a letter to Naomi Mitchison:

“I think at the present moment you are in a state of mind that hungers for the disaster it fears. If there are these forces of evil you see you are siding with them in allowing your thought to panic. Your mind is your own province—the only thing that is. Yes, this brings up another point. There is a sort of hubris in this unreal worrying. For if you have achieved peace in your own mind when the worse happens (if it does) you will have reserves of strength to meet it. And if you have not achieved peace in your own mind how can you expect the world to do any better. You are the world and so am I. And at the moment the world is a great deal too articulate! (You will agree!!) and worries too much and so on.”

Quoted in Mitchison’s memoir, You May Well Ask (London: Gollancz, 1979). p. 155.
