“Free speech is not to be regulated like diseased cattle and impure butter. The audience … that hissed yesterday may applaud today, even for the same performance.”

On Literature, Revolution, Entropy and Other Matters (1923)
Context: A new form is not intelligible to everyone; many find it difficult. Perhaps. The ordinary, the banal is, of course, simpler, more pleasant, more comfortable. Euclid's world is very simple, and Einstein's world is very difficult — but it is no longer possible to return to Euclid. No revolution, no heresy is comfortable or easy. For it is a leap, it is a break in the smooth evolutionary curve, and a break is a wound, a pain. But the wound is necessary: most of mankind suffers from hereditary sleeping sickness, and victims of this sickness (entropy) must not be allowed to sleep, or it will be their final sleep, death.
The same disease often afflicts artists and writers: they sink into satiated slumber in forms once invented and twice perfected. And they lack the strength to wound themselves, to cease loving what they once loved, to leave their old, familiar apartments filled with the scent of laurel leaves and walk away into the open field, to start anew.
Of course, to wound oneself is difficult, even dangerous. But for those who are alive, living today as yesterday and yesterday as today is still more difficult.

Gestern war Concert Spirituel. Die Symphonie von Haydn war allerliebst und die Exekution vorzüglich gut. Mlle Wendling und ein welscher Tenorist Giuliano wurden ausgepfiffen. Danner und ein andrer welscher Geiger Giuliani wurden allgemein beklatscht. Eine Symphonie concertante von den Gebrüdern und Söhnen Thonberg [Romberg] fand Beifall. Das Konzert auf dem Fagotte von Devienne so so.

"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.

Larry King Interview (8 September 2003)
Context: Seems like yesterday; seems like forever—all at the same time. It's sort of, how do you measure it? Do you measure the fact that I'm 20 years older? No. I think I measure it by the events. You know, I came just as the Cold War was coming to an end. When you think about the events that we've been through, from the fall of the Berlin Wall to, I guess you'd say, 9/11 being the culmination at the end of that — of that scope — what extraordinary changes there have been.
