“The atoms, you know, have a cyclic motion. The stable compounds are made of constituents that have a regular, periodic motion relative to one another. In fact, it is the tiny time-reversible cycles of the atom that give matter enough permanence that evolution is possible. The little timelessnesses added together make up time. And then on the big scale, the cosmos: well, you know we think that the whole universe is a cyclic process, an oscillation of expansion and contraction, without any before or after. Only within each of the great cycles, where we live, only there is there linear time, evolution, change. So then time has two aspects. There is the arrow, the running river, without which there is no change, no progress, or direction, or creation. And there is the circle or the cycle, without which there is chaos, meaningless succession of instants, a world without clocks or seasons or promises.”

“Once upon a time there had been a Belter girl named Naomi Nagata, and now there was a woman. Even though the difference between the two had been created a day, an hour, a minute at a time, the Venn diagram of the two almost didn’t overlap. What could be cut away, she’d cut years ago. What remained did so in spite of her efforts. For the most part, she could work around them.”

“You go into a situation thinking about it a particular way, and then something changes. Then either you stick with the ideas you had before or you look at everything you have to work with and find a new shape.”

“Yes. Exactly. Everyone thinks that it’s simple. New, invasive species comes in and it has an advantage and it outcompetes, right? That’s the story, but there’s another part to that. Always, always, the local environment resists. Yes, yes, maybe badly. Maybe without a clear idea of coping with novelty. I’m not saying it’s perfect, but I am saying it’s there. Even when an invasive species takes over, even when it wins, there is a counterbalancing process it has to overcome to do that. And—” The tall man was scowling, and his discomfort made Prax want to speak faster. To say everything he had in his heart before the hammer fell. “And that counterprocess is so deep in the fabric of living systems, it can never be absent. However well the new species is designed, however overwhelming its advantages seem to be, the pushback will always be there. If one native impulse is overcome, there will be another. You understand? Conspecifics are outcompeted? Fine, the bacterial and viral microecologies will push back. Adapt to those, and it’ll be micronutrient levels and salinity and light. And the thing is, the thing is, even when the novel species does win? Even when it takes over every niche there is, that struggle alone changes what it is. Even when you wipe out or co-opt the local environment completely, you’re changed by the pushback. Even when the previous organisms are driven to extinction, they leave markers behind. What they are can never, never be completely erased.”
