It was a ploy, Jaar. I was trying to manipulate you, to get you to fight, to make you do what I wanted you to do." "I know that." He smiled. "Of cour… - Stephen Baxter

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.

I have always been distrustful of personal power—for I have met not one man wise enough to be entrusted with it.

The fault is all ours. We have become overwhelming. About one in twenty of all the people who have ever existed is alive today, compared to just one in a thousand of other species. As a result we are depleting the earth.
But even now the question is still asked: Does it really matter? So we lose a few cute mammals, and a lot of bugs nobody ever heard of. So what? We’re still here.
Yes, we are. But the ecosystem is like a vast life-support machine. It is built on the interaction of species on all scales of life, from the humblest fungi filaments that sustain the roots of plants to the tremendous global cycles of water, oxygen, and carbon dioxide. Darwin’s entangled bank, indeed. How does the machine stay stable? We don’t know. Which are its most important components? We don’t know. How much of it can we take out safely? We don’t know that either. Even if we could identify and save the species that are critical for our survival, we wouldn’t know which species they depend on in turn. But if we keep on our present course, we will soon find out the limits of robustness.
I may be biased, but I believe it will matter a great deal if we were to die by our own foolishness. Because we bring to the world something that no other creature in all its long history has had, and that is conscious purpose. We can think our way out of this.
So my question is—consciously, purposefully, what are we going to do?
