“What we are fighting, in Islamist extremism, is an ideology. It is an extreme doctrine. And like any extreme doctrine, it is subversive. At its furthest end it seeks to destroy nation-states to invent its own barbaric realm. And it often backs violence to achieve this aim – mostly violence against fellow Muslims – who don’t subscribe to its sick worldview. But you don’t have to support violence to subscribe to certain intolerant ideas which create a climate in which extremists can flourish. Ideas which are hostile to basic liberal values such as democracy, freedom and sexual equality. Ideas which actively promote discrimination, sectarianism and segregation. Ideas – like those of the despicable far right – which privilege one identity to the detriment of the rights and freedoms of others. And ideas also based on conspiracy: that Jews exercise malevolent power; or that Western powers, in concert with Israel, are deliberately humiliating Muslims, because they aim to destroy Islam. In this warped worldview, such conclusions are reached – that 9/11 was actually inspired by Mossad to provoke the invasion of Afghanistan; that British security services knew about 7/7, but didn’t do anything about it because they wanted to provoke an anti-Muslim backlash. And like so many ideologies that have existed before – whether fascist or communist – many people, especially young people, are being drawn to it. We need to understand why it is proving so attractive.”

The evil is not what they say about their cause, but what they say about their opponents.

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.
As quoted in Solzhenitsyn: A Documentary Record (1974) edited by Leopold Labedz
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.

1930s
Context: It is my firm conviction that if the State suppressed capitalism by violence, it will be caught in the coils of violence itself, and fail to develop non-violence at any time. The state represents violence in a concentrated and organized form. The Individual has a soul, but as the state is a soulless machine, it can never be weaned from violence to which it owes its very existence.

Draft for a Statement of Human Obligation (1943), Statement Of Obligations
Context: The human soul has need of disciplined participation in a common task of public value, and it has need of personal initiative within this participation.
The human soul has need of security and also of risk. The fear of violence or of hunger or of any other extreme evil is a sickness of the soul. The boredom produced by a complete absence of risk is also a sickness of the soul.
