Bzya touched his shoulder. “But that’s why you and I are here, old man. To keep the world away from boys like Farr and Cris—to give them a place that seems as stable and eternal as your parents did when you were a child—until they are old enough to cope with the truth.”

One might imagine that, in any conflict between rational humans and religious humans, the rational ought to win. After all, it is rationality that invented gunpowder! And yet—at least up to our nineteenth century—the religious tendency has generally won out, and natural selection operated, leaving us with a population of religiously-inclined sheep—it has sometimes seemed to me—capable of being deluded by any smooth-tongued preacher.
The paradox is explained because religion provides a goal for men to fight for. The religious man will soak some bit of “sacred” land with his blood, sacrificing far more than the land’s intrinsic economic or other value.

No organization was a rational place. Organizations were bear pits where people fought for their own projects, which might or might not have something to do with the organization’s supposed mission. The wise person accepted that, and found a way to get what she wanted in spite of it all.

We'd carve a place out of the wilderness—"
"But there is no wilderness, Mane said. "Even without war, even if you found a space not already cultivated, you would be forced to occupy a region, delineated in space, time, and energy flow, already exploited by another portion of the ecology."
It took some time for Emma to figure that out. "Yes," she said. "There is bound to be some environmental impact. But—"
"Other species would find reduced living space. Diversity would fall. And so it would go on. Soon the world would be covered from pole to pole by humans, fighting over the diminishing resources.

If this was the basis of the faith of the Friends, then no wonder the Friends were so remote, so intense—so careless of their everyday lives, of the pain and death of others. History as it existed was nothing more than a shabby prototype of the global optimization to come, when the Ultimate Observer discarded all inferior worldlines.
And no wonder then, he thought, the Friends were so leached of humanity. Their mystical vision had removed all significance from their own lives—the only lives they could experience, whatever the truth of their philosophy—and it had rendered them deeply flawed, less than human. He opened his eyes and studied Shira. He saw again the patient intensity which resided inside this fragile girl—and he saw now how damaged she was by her philosophy.
She was not fully alive, and perhaps never could be; he pitied her, he realized.

Despite his friendship with Adam Smith, he believed in government intervention in agriculture, as it was too important to be left to market forces and chance: ‘The husbandman maintains the nation in all its ease, its affluence and its splendour,’ he wrote. But farmers too had a responsibility for the public good. Rotation of crops, ensuring equal acreages of different crops at any given time, would help keep prices stable.

Her story was a creation myth, a legend already more than twenty thousand years old. Such tales—which said that Jahna’s people were the pinnacle of creation, that theirs was the only right way, and that all others were less than human—taught the people to care passionately about themselves, their kin, and a few treasured ideals.
But to the exclusion of all other humans, let alone such non-people as the Old Man’s kind.
