“[A]ny species that exempts itself from the rules of competition ends up destroying the community in order to support its own expansion.”

“The rules that govern competition between species are (and must be) very different from the rules that govern competition within species.”

“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.”

“Diversity is a survival factor for the community itself. A community of a hundred million species can survive anything short of total global catastrophe. Within that hundred million will be thousands that could survive a global temperature drop of twenty degrees—which would be a lot more devastating than it sounds. Within that hundred million will be thousands that could survive a global temperature rise of twenty degrees. But a community of a hundred species or a thousand species has almost no survival value at all.”

“This law … defines the limits of competition in the community of life. You may compete to the full extent of your capabilities, but you may not hunt down your competitors or destroy their food or deny them access to food. In other words, you may compete but you may not wage war.”

“No one species shall make the life of the world its own.' … That's one expression of the law. Here's another: 'The world was not made for any one species.”

“This is considered almost holy work by farmers and ranchers. Kill off everything you can't eat. Kill off anything that eats what you eat. Kill off anything that doesn't feed what you eat.""It IS holy work, in Taker culture. The more competitors you destroy, the more humans you can bring into the world, and that makes it just about the holiest work there is. Once you exempt yourself from the law of limited competition, everything in the world except your food and the food of your food becomes an enemy to be exterminated.”
