“Demos are mock battles, never the real thing. Everybody knows where they're going to happen, and when and why. Nobody gets seriously hurt. Well, not unless they ask for it. (ch. 4)”

“There's no way out," he announced with satisfaction, "and no amount of wishful dreaming will produce one. The demon won't go back in its bottle, the face-off is for ever, the embrace gets tighter and the toys cleverer with every generation, and there's no such thing for either side as enough security. Not for the main players, not for the nasty little newcomers who each year run themselves up a suitcase bomb and join the club. We get tired of believing that, because we're human. We may even con ourselves into believing the threat has gone away. It never will. Never, never, never.""So, who'll save us then, Walt?" Barley asked.

“Smiley himself was one of those solitaires who seem to have come into the world fully educated at the age of eighteen. Obscurity was his nature, as well as his profession. The byways of espionage are not populated by the brash and colourful adventurers of fiction. A man who, like Smiley, has lived and worked for years among his country's enemies learns only one prayer: that he may never, never be noticed. Assimilation is his highest aim, he learns to love the crowds who pass him in the street without a glance; he clings to them for his anonimity and his safety. His fear makes him servile - he could embrace the shoppers who jostle him in their impatience, and force him from the pavement. He could adore the officials, the police, the bus conductors, for the terse indifference of their attitudes. (ch. 9)”

“What else has a journalist to do these days, after all, but report life's miseries?”

“Unfortunately it is the weak who destroy the strong.”
