Solzhenitsyn here seems to be paraphrasing Sophocles who expresses similar ideas in Oedipus Rex. This is also a direct reference to Plutarch's line, "call no man fortunate until he is dead," from his "Parallel Lives".
The Oak and the Calf (1975)

“A work of art bears within itself its own verification: conceptions which are devised or stretched do not stand being portrayed in images, they all come crashing down, appear sickly and pale, convince no one. But those works of art which have scooped up the truth and presented it to us as a living force — they take hold of us, compel us, and nobody ever, not even in ages to come, will appear to refute them.”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Nobel lecture (1970)

“From time immemorial man has been made in such a way that his vision of the world, so long as it has not been instilled under hypnosis, his motivations and scale of values, his actions and intentions are determined by his personal and group experience of life.”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Nobel lecture (1970)

“I am of course confident that I will fulfil my tasks as a writer in all circumstances — from my grave even more successfully and more irrefutably than in my lifetime. No one can bar the road to truth, and to advance its cause I am prepared to accept even death. But may it be that repeated lessons will finally teach us not to stop the writer’s pen during his lifetime? At no time has this ennobled our history.”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Open letter to the Fourth Soviet Writers’ Congress (16 May 1967); as translated in Solzhenitsyn: A Documentary Record (1970) edited by Leopold Labedz (1970).

“If only there were evil people somewhere insidiously committing evil deeds, and it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being. And who is willing to destroy a piece of his own heart?”

Aleksandr Solzhenitsyn book The Gulag Archipelago

The Gulag Archipelago (1973).

“The disappearance of nations would impoverish us no less than if all peoples were made alike, with one character, one face. Nations are the wealth of mankind, they are its generalized personalities: the smallest of them has its own particular colors, and embodies a particular facet of God's design.”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Harvard University address (1978)

“Untouched by the breath of God, unrestricted by human conscience, both capitalism and socialism are repulsive.”

“In our country the lie has become not just a moral category but a pillar of the State.”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

As quoted in The Observer (29 December 1974).

“A decline in courage may be the most striking feature that an outside observer notices in the West today. The Western world has lost its civic courage, both as a whole and separately, in each country, in each government, in each political party, and, of course, in the United Nations. Such a decline in courage is particularly noticeable among the ruling and intellectual elites, causing an impression of a loss of courage by the entire society. There are many courageous individuals, but they have no determining influence on public life.
Political and intellectual functionaries exhibit this depression, passivity, and perplexity in their actions and in their statements, and even more so in their self-serving rationales as to how realistic, reasonable, and intellectually and even morally justified it is to base state policies on weakness and cowardice. And the decline in courage, at times attaining what could be termed a lack of manhood, is ironically emphasized by occasional outbursts and inflexibility on the part of those same functionaries when dealing with weak governments and with countries that lack support, or with doomed currents which clearly cannot offer resistance. But they get tongue-tied and paralyzed when they deal with powerful governments and threatening forces, with aggressors and international terrorists.
Should one point out that from ancient times decline in courage has been considered the beginning of the end?”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Harvard University address (1978)

“If humanism were right in declaring that man is born to be happy, he would not be born to die. Since his body is doomed to die, his task on earth evidently must be of a more spiritual nature. It cannot be unrestrained enjoyment of everyday life. It cannot be the search for the best ways to obtain material goods and then cheerfully get the most out of them. It has to be the fulfillment of a permanent, earnest duty so that one's life journey may become an experience of moral growth, so that one may leave life a better human being than one started it. It is imperative to review the table of widespread human values. Its present incorrectness is astounding. It is not possible that assessment of the President's performance be reduced to the question of how much money one makes or of unlimited availability of gasoline. Only voluntary, inspired self-restraint can raise man above the world stream of materialism.”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Harvard University address (1978)

“But the fight for our planet, physical and spiritual, a fight of cosmic proportions, is not a vague matter of the future; it has already started. The forces of Evil have begun their decisive offensive, you can feel their pressure, and yet your screens and publications are full of prescribed smiles and raised glasses. What is the joy about?”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Harvard University address (1978)

“Macbeth’s self-justifications were feeble – and his conscience devoured him. Yes, even Iago was a little lamb too. The imagination and the spiritual strength of Shakespeare’s evildoers stopped short at a dozen corpses. Because they had no ideology.”

“The clock of communism has stopped striking. But its concrete building has not yet come crashing down. For that reason, instead of freeing ourselves, we must try to save ourselves from being crushed by its rubble.”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

"How We Must Rebuild Russia" in Komsomolskaya Pravda (18 September 1990).

“What then is the place and role of the writer in this cruel, dynamic, split world on the brink of its ten destructions? After all we have nothing to do with letting off rockets, we do not even push the lowliest of hand-carts, we are quite scorned by those who respect only material power. Is it not natural for us too to step back, to lose faith in the steadfastness of goodness, in the indivisibility of truth, and to just impart to the world our bitter, detached observations: how mankind has become hopelessly corrupt, how men have degenerated, and how difficult it is for the few beautiful and refined souls to live amongst them?
But we have not even recourse to this flight. Anyone who has once taken up the WORD can never again evade it; a writer is not the detached judge of his compatriots and contemporaries, he is an accomplice to all the evil committed in his native land or by his countrymen.”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Nobel lecture (1970)

“We shall be told: what can literature possibly do against the ruthless onslaught of open violence? But let us not forget that violence does not live alone and is not capable of living alone: it is necessarily interwoven with falsehood. Between them lies the most intimate, the deepest of natural bonds. Violence finds its only refuge in falsehood, falsehood its only support in violence. Any man who has once acclaimed violence as his METHOD must inexorably choose falsehood as his PRINCIPLE.”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Variant translation: Violence can only be concealed by a lie, and the lie can only be maintained by violence. Any man who has once proclaimed violence as his method is inevitably forced to take the lie as his principle.

Nobel lecture (1970)
Context: We shall be told: what can literature possibly do against the ruthless onslaught of open violence? But let us not forget that violence does not live alone and is not capable of living alone: it is necessarily interwoven with falsehood. Between them lies the most intimate, the deepest of natural bonds. Violence finds its only refuge in falsehood, falsehood its only support in violence. Any man who has once acclaimed violence as his METHOD must inexorably choose falsehood as his PRINCIPLE. At its birth violence acts openly and even with pride. But no sooner does it become strong, firmly established, than it senses the rarefaction of the air around it and it cannot continue to exist without descending into a fog of lies, clothing them in sweet talk. It does not always, not necessarily, openly throttle the throat, more often it demands from its subjects only an oath of allegiance to falsehood, only complicity in falsehood.
