“Strange, when you come to think of it, that of all the countless folk who have lived before our time on this planet not one is known in history or in legend as having died of laughter.”

"Campo dei Fiori" (1943), trans. Louis Iribarne and David Brooks
Rescue (1945)
Context: Those dying here, the lonely
Forgotten by the world,
Our tongue becomes for them
The language of an ancient planet.
Until, when all is legend
And many years have passed,
On a great Campo di Fiori
Rage will kindle at a poet's word.

Variant: Cowards die many times before their deaths;
The valiant never taste of death but once.
Of all the wonders that I yet have heard,
It seems to me most strange that men should fear;
Seeing that death, a necessary end,
Will come when it will come.

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.”

Context: Do we walk in legends or on the green earth in the daylight? A man may do both, said Aragorn. For not we but those who come after will make the legends of our time. The green earth, say you? That is a mighty matter of legend, though you tread it under the light of day!

As quoted in The Discovery of Nature (1965), by Albert W. Bettex
Context: There are countless suns and countless earths all rotating round their suns in exactly the same way as the seven planets of our system. We see only the suns because they are the largest bodies and are luminous, but their planets remain invisible to us because they are smaller and non-luminous. The countless worlds in the universe are no worse and no less inhabited than our earth. For it is utterly unreasonable to suppose that those teeming worlds which are as magnificent as our own, perhaps more so, and which enjoy the fructifying rays of a sun just as we do, should be uninhabited and should not bear similar or even more perfect inhabitants than our earth. The unnumbered worlds in the universe are all similar in form and rank and subject to the same forces and the same laws. Impart to us the knowledge of the universality of terrestrial laws throughout all worlds and of the similarity of all substances in the cosmos! Destroy the theories that the earth is the center of the universe! Crush the supernatural powers said to animate the world, along with the so-called crystalline spheres! Open the door through which we can look out into the limitless, unified firmament composed of similar elements and show us that the other worlds float in an ethereal ocean like our own! Make it plain to us that the motions of all the worlds proceed from inner forces and teach us in the light of such attitudes to go forward with surer tread in the investigation and discovery of nature! Take comfort, the time will come when all men will see as I do.
