“The heart has a resiliency. Strained to breaking, it can contract again. Even the waiting women, Iseult and Penelope, learned, as they sat sorrowing and watching, to sing to the swing of the sea.”

The Ballot or the Bullet (1964), Speech in Detroit, Michigan (12 April 1964)
Context: The government has failed us; you can’t deny that. Anytime you live in the twentieth century, 1964, and you’re walking around here singing “We Shall Overcome,” the government has failed us. This is part of what’s wrong with you -- you do too much singing. Today it’s time to stop singing and start swinging. You can’t sing up on freedom, but you can swing up on some freedom. Cassius Clay can sing, but singing didn’t help him to become the heavyweight champion of the world; swinging helped him become the heavyweight champion.

Sam.

Context: Van Helsing and I came on here. The moment we were alone in the carriage he gave way to a regular fit of hysterics. He has denied to me since that it was hysterics, and insisted that it was only his sense of humour asserting itself under very terrible conditions. He laughed till he cried, and I had to draw down the blinds lest any one should see us and misjudge; and then he cried, till he laughed again; and laughed and cried together, just as a woman does. I tried to be stern with him, as one is to a woman under the circumstances; but it had no effect. Men and women are so different in manifestations of nervous strength or weakness! Then when his face grew grave and stern again I asked him why his mirth, and why at such a time. His reply was in a way characteristic of him, for it was logical and forceful and mysterious. He said:—
“Ah, you don't comprehend, friend John. Do not think that I am not sad, though I laugh. See, I have cried even when the laugh did choke me. But no more think that I am all sorry when I cry, for the laugh he come just the same. Keep it always with you that laughter who knock at your door and say, ‘May I come in?’ is not the true laughter. No! he is a king, and he come when and how he like. He ask no person; he choose no time of suitability. He say, ‘I am here.’ Behold, in example I grieve my heart out for that so sweet young girl; I give my blood for her, though I am old and worn; I give my time, my skill, my sleep; I let my other sufferers want that so she may have all. And yet I can laugh at her very grave — laugh when the clay from the spade of the sexton drop upon her coffin and say ‘Thud, thud!’ to my heart, till it send back the blood from my cheek. My heart bleed for that poor boy — that dear boy, so of the age of mine own boy had I been so blessed that he live, and with his hair and eyes the same. There, you know now why I love him so. And yet when he say things that touch my husband-heart to the quick, and make my father-heart yearn to him as to no other man — not even you, friend John, for we are more level in experiences than father and son — yet even at such a moment King Laugh he come to me and shout and bellow in my ear, ‘Here I am! here I am!’ till the blood come dance back and bring some of the sunshine that he carry with him to my cheek. Oh, friend John, it is a strange world, a sad world, a world full of miseries, and woes, and troubles; and yet when King Laugh come, he make them all dance to the tune he play. Bleeding hearts, and dry bones of the churchyard, and tears that burn as they fall — all dance together to the music that he make with that smileless mouth of him. And believe me, friend John, that he is good to come, and kind. Ah, we men and women are like ropes drawn tight with strain that pull us different ways. Then tears come; and, like the rain on the ropes, they brace us up, until perhaps the strain become too great, and we break. But King Laugh he come like the sunshine, and he ease off the strain again; and we bear to go on with our labour, what it may be.”
