"The plow has probably done more harm — in the long run — than the sword."

“Has joy any survival value in the operations of evolution? I suspect that it does; I suspect that the morose and fearful are doomed to quick extinction. Where there is no joy there can be no courage; and without courage all other virtues are useless.”

“The tank, the B-52, the fighter-bomber, the state-controlled police and military are the weapons of dictatorship. The rifle is the weapon of democracy. Not for nothing was the revolver called an "equalizer." Egalite implies liberte. And always will. Let us hope our weapons are never needed — but do not forget what the common people of this nation knew when they demanded the Bill of Rights: An armed citizenry is the first defense, the best defense, and the final defense against tyranny. If guns are outlawed, only the government will have guns. Only the police, the secret police, the military, the hired servants of our rulers. Only the government – and a few outlaws. I intend to be among the outlaws.”

“'Don't let yourself become cynical. Cynicism is a cheap emotion, a craven substitute for thought and action. Cynicism corrodes the will, dulls the conscience, blunts your sense of right and wrong... Stay alert to fine distinctions: become a pessimist like me.'”

“My loyalties will not be bound by national borders, or confined in time by one nation's history, or limited in the spiritual dimension by one language and culture. I pledge my allegiance to the damned human race, and my everlasting love to the green hills of Earth, and my intimations of glory to the singing stars, to the very end of space and time.”

“God is a sound people make when they're too tired to think anymore.”

“Most academic economists know nothing of economy. In fact, they know little of anything.”
