"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.
“There are so many things that we wish we had done yesterday, so few that we feel like doing today.”

Love's Voice (c.1935–1939)
Context: Such fable ours! However sweet,
That earlier hope had, if fulfilled,
Been but child's pap and toothless meat
— And meaning blunt and deed unwilled,
And we but motes that dance in light
And in such light gleam like the core
Of light, but lightless, are in right
Blind dust that fouls the unswept floor
For, no: not faith by fable lives,
But from the faith the fable springs
— It never is the song that gives
Tongue life, it is the tongue that sings;
And sings the song. Then, let the act
Speak, it is the unbetrayable
Command, if music, let the fact
Make music's motion; us, the fable.
