“How can you pass laws about things that nobody knows?""They do it all the time," says Hayden. "That's what law is: educated guesses at right and wrong.”

“That's what law is: educated guesses at right and wrong.”

“In general, we look for a new law by the following process: First we guess it; then we compute the consequences of the guess to see what would be implied if this law that we guessed is right; then we compare the result of the computation to nature, with experiment or experience, compare it directly with observation, to see if it works. If it disagrees with experiment, it is wrong. In that simple statement is the key to science. It does not make any difference how beautiful your guess is, it does not make any difference how smart you are, who made the guess, or what his name is — if it disagrees with experiment, it is wrong.”

“People have a right to do anything that's not forbidden by law, and there's no law against lying to you.”

“But I guess the thing about fear is that it defies the laws of rationality. It creates its own laws instead.”

“A week ago," Ishmael said, "when we were talking about laws, you said that there's only one kind of law about how people should live--the kind that can be changed by a vote. What do you think now? Can the laws that govern competition in the community be changed by a vote?""No. But they're not absolutes, like the laws of aerodynamics. They can be broken.""Can't the laws of aerodynamics be broken?""No. If your plane isn't built according to the law, it doesn't fly.""But if you push it off a cliff, it stays in the air, doesn't it?""For a while.""The same is true of a civilization that isn't built in accordance with the law of limited competition... Any species that, as a matter of policy, exempts itself from the law of limited competition will end by destroying the community...""Yes.""Then what have we discovered here?""We've discovered a piece of certain knowledge about how people ought to live. Must live in fact.""The law we've outlined here enables species to live--enables species to survive, including the human. It won't tell you whether mood-altering drugs should be legalized or not. It won't tell you whether premarital sex is good or bad. It won't tell you if capital punishment is right or wrong. It *will* tell you how you have to live if you want to avoid extinction, and that's the first and most fundamental knowledge anyone needs... You might say that this is one of the law's basic operations: Those who threaten the stability of the community by defying the law automatically eliminate themselves.”
