“504. All between the Cradle and the Coffin is uncertain.”

A Man From Lebanon: Nineteen Centuries Afterward
Jesus, The Son of Man (1928)
Context: Here and there, betwixt the cradle and the coffin, I meet your silent brothers,
The free men, unshackled,
Sons of your mother earth and space.
They are like the birds of the sky,
And like the lilies of the field.
They live your life and think your thoughts,
And they echo your song.
But they are empty-handed,
And they are not crucified with the great crucifixion,
And therein is their pain.
The world crucifies them every day,
But only in little ways.
The sky is not shaken,
And the earth travails not with her dead.

Speak, Memory: A Memoir (1951)
Context: The cradle rocks above an abyss, and common sense tells us that our existence is but a brief crack of light between two eternities of darkness. Although the two are identical twins, man, as a rule, views the prenatal abyss with more calm than the one he is heading for (at some forty-five hundred heartbeats an hour).

From a letter written in 1911
Usually cited as Earth is the cradle of humanity, but one cannot live in a cradle forever. http://web.archive.org/web/20060421175318/http://www.uranos.eu.org/biogr/ciolke.html

"Tomorrow" (1919), as translated in A Soviet Heretic : Essays by Yevgeny Zamyatin (1970) edited and translated by Mirra Ginsburg
Context: Every today is at the same time both a cradle and a shroud: a shroud for yesterday, a cradle for tomorrow. Today, yesterday, and tomorrow are equally near to one another, and equally far. They are generations, they are grandfathers, fathers, and grandsons. And grandsons invariably love and hate the fathers; the fathers invariably hate and love the grandfathers.
Today is doomed to die — because yesterday died, and because tomorrow will be born. Such is the wise and cruel law. Cruel, because it condemns to eternal dissatisfaction those who already today see the distant peaks of tomorrow; wise, because eternal dissatisfaction is the only pledge of eternal movement forward, eternal creation. He who has found his ideal today is, like Lot's wife, already turned to a pillar of salt, has already sunk into the earth and does not move ahead. The world is kept alive only by heretics: the heretic Christ, the heretic Copernicus, the heretic Tolstoy. Our symbol of faith is heresy: tomorrow is an inevitable heresy of today, which has turned into a pillar of salt, and to yesterday, which has scattered to dust. Today denies yesterday, but is a denial of denial tomorrow. This is the constant dialectic path which in a grandiose parabola sweeps the world into infinity. Yesterday, the thesis; today, the antithesis, and tomorrow, the synthesis.
