"Before you can be an internationalist you have first to be a naturalist and feel the ground under you making a whole circle. It is easier for a man to be loyal to his club than to his planet; the bylaws are shorter, and he is personally acquainted with the other members. A club, moreover, or a nation, has a most attractive offer to make: it offers the right to be exclusive. There are not many of us who are physically constituted to resist this strange delight, this nourishing privilege. It is at the bottom of all fraternities, societies, orders. It is at the bottom of most trouble. The planet holds out no such inducement. The planet is everybody's. All it offers is the grass, the sky, the water, the ineluctable dream of peace and fruition."

“Government is the thing. Law is the thing. Not brotherhood, not international cooperation, not security councils that can stop war only by waging it... Where does security lie, anyway — security against the thief, a bad man, the murderer? In brotherly love? Not at all. It lies in government.”

“Humor can be dissected, as a frog can, but the thing dies in the process and the innards are discouraging to any but the pure scientific mind.”

“We grow tyrannical fighting tyranny... The most alarming spectacle today is not the spectacle of the atomic bomb in an unfederated world, it is the spectacle of the Americans beginning to accept the device of loyalty oaths and witchhunts, beginning to call anybody they don't like a Communist.”

“I am a member of a party of one, and I live in an age of fear. Nothing lately has unsettled my party and raised my fears so much as your editorial, on Thanksgiving Day, suggesting that employees should be required to state their beliefs in order to hold their jobs. The idea is inconsistent with our constitutional theory and has been stubbornly opposed by watchful men since the early days of the Republic.”

“Security, for me, took a tumble not when I read that there were Communists in Hollywood but when I read your editorial in praise of loyalty testing and thought control. If a man is in health, he doesn't need to take anybody else's temperature to know where he is going.”

“Sailors have an expression about the weather: they say the weather is a great bluffer. I guess the same is true of our human society — things can look dark, then a break shows in the clouds, and all is changed.”
