“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. "You and Nedsky?""Vanity, if anything will, which I doubt," Walter retorted. "No leader wants to go down in history as the ass who destroyed his country in an afternoon. And funk, I suppose. Most of our gallant politicians do have a narcissistic objection to suicide, thank God.”

“I have a theory which I suspect is rather immoral,' Smiley went on, more lightly. 'Each of us has only a quantum of compassion. That if we lavish our concern on every stray cat, we never get to the centre of things.”

“You're history, Donohue. You think countries run the fucking world! Go back to fucking Sunday school. It's 'God save our multinational' they're singing these days.”

“Look... we're getting to be old men, and we've spent our lives looking for the weaknesses in one another's systems. I can see through Eastern values just as you can see through our Western ones. Both of us, I am sure, have experienced ad nauseam the technical satisfactions of this wretched war. But now your own side is going to shoot you. Don't you think it's time to recognise that there is as little worth on your side as there is on mine?”

“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)”

“CIA Interrogator:Have you ever met any jazz musicians you would describe, or who would describe themselves, as anarchists?Bartholomew 'Barley' Scott Blair:Hmmm... ah, there was a trombone player, Wilfred Baker.Bartholomew 'Barley' Scott Blair:He's the only jazz musician I can think of who is completely devoid of anarchist tendencies.”

“What would it be like really and absolutely to believe? (...) To know, really and absolutely know, that there's a Divine Being not set in time or space who reads your thoughts better than you ever did, and probably before you even have them? To believe that God sends you to war, God bends the path of bullets, decides which of his children will die, or have their legs blown off, or make a few hundred million on Wall Street, depending on today's Grand Design? (ch. 14)”
