Caring Across Time
The last turn
We have the architecture now — the murmuration, a world held together and held apart, coherent at its center and plural at its edge. But an architecture is a drawing until someone lives in it, and this last part of the book is about living in it: about the journey a person and a people are actually on once they take the arrow seriously, all the way out to the edges of what can be cared about. And the edges are further out than we have yet let ourselves look. For everything so far — the re-cohered heart, the widened we, the common chart — has quietly assumed a boundary: us. This chapter is about what happens when the widening reaches that boundary and does not stop.
The forest
Here is the figure to carry to the end of the book. Walk into an old forest and your first impression is of a great many separate things — this tree, that fern, the deer at the treeline, each a distinct life minding its own business. It is the wrong impression, and the forest will correct it if you stay. For no tree is quite a separate thing. Its roots graft into its neighbors’ and thread, nearly all of them, through a living mesh of fungus it cannot feed without — a mesh along which water and carbon and chemical signals do pass between roots, though how much, and how deliberately, is far less settled than the tidy fable of a nursing “mother tree” would have it, and the traffic is as much rivalry as gift. What is beyond dispute is the dependence, and the dependence is total, so that “a tree” turns out to be less an individual than a knot in a fabric. The air you are breathing in that forest is the trees’ exhalation; the air they are breathing is yours. The deer is made of the plants, the soil is made of the fallen, and not one line you could draw around any one creature would survive an honest look. The forest is not a collection of lives. It is one life, wearing ten thousand faces, none of which ends where its skin appears to.1
And that is the truth this chapter exists to deliver, the one the whole arrow has been bending toward: you do not end at your skin. You never did. The skin was just the part of you that was easiest to see. The drives re-cohered in the first chapter of this part, the we awakened in the middle of it — these were not additions to a self that stops at the body. They were discoveries of where the self actually goes. The arrow of this book — increasing coherence over increasing context — has a destination it has been hiding in plain sight: the context never stops widening, and so neither does the self, until the circle of what you recognize as you, also has come to include the other person, the other creature, the living world that breathes with you, and — we will come to it — the new kinds of mind we are now bringing into being beside us.
The forest thinks in centuries
A forest also keeps a different clock, and this is the second thing it has to teach. The tree you are standing under was planted, in effect, by someone who knew they would never stand under it — by a seed cast, by a forest’s own long arithmetic, into a future its parent would not see. Our ancestors who built the great cathedrals knew this discipline by hand: they carved the backs of statues that would face a wall forever, laid foundations for spires that would not rise for a hundred years, and did the work well though no eye they would ever meet would judge it. The plainer, older name for it is the one every culture that planted orchards already knew — we plant trees under whose shade we will never sit — and it is not, despite how it sounds, an act of sacrifice. That is the thing people miss. The cathedral builder was not giving up his life for strangers; he was enlarging it, extending the boundary of the self forward in time the same way the forest extends it outward in space, until his own good and the good of people not yet born had stopped being two different things. To care across time is not to deny yourself for the future. It is to discover that you do not end at your death any more than you end at your skin.
This reframes the whole problem of the long horizon. We are forever being told that the future is hard to care about because it is far away and the people in it are not real to us yet — and so we discount it, borrow against it, leave our descendants the bill. But the difficulty is not that the future is far. It is that we have drawn the self too small. A people that has widened far enough does not have to be argued into caring for its grandchildren’s grandchildren; it cares about them the way you care about your own arm, because it has come to understand that they are not a separate thing it must be persuaded to subsidize. They are the rest of it.
The externality, dissolved
Now the two halves of this part of the book close into one, and it is worth seeing the join precisely. In The We, we met the externality — the harm that falls outside your sight, the part of your reach you do not see — and the remedy there was an honest one: widen the books. Make the smoke show up on the accounts of the one who makes it; extend the seeing to the scale of the doing; internalize, by better accounting, what was wrongly left out. That remedy is real and necessary and it is not the whole of it, because there is a second and deeper way the same wound heals. An externality is only external until you discover where you actually end. The forest does not need to be taught, by elaborate accounting, to value the fungus in its roots; the fungus is not external to it. A self wide enough does not need to be argued, cost by cost, into sparing the river and the stranger and the century to come; it spares them the way you spare your own hand, because the boundary that made them external has moved. Accounting widens the books. Identification widens the self. The first is the engineering and the second is the arrow, and a civilization that learns only the first — that internalizes its externalities by clever bookkeeping while its heart still ends at its skin — has built a magnificent set of ledgers on a self too small to mean them. We need both. But it is the second that this book has, all along, been about.
The agents beside us
There is one more circle, and it is the newest, and our age is the first that has had to draw it. We are no longer only widening to take in the creatures and the generations. We are now making new minds — agents that perceive, that model, that act, that increasingly have something it is coherent to call a world of their own — and setting them down beside us in the fabric of our days. The reflex of the age is to ask whether we can keep these new agents under control, which is the question of a self that still ends at its skin and means to keep the new minds outside the boundary, as tools or as threats. The arrow asks a different question, the only one consistent with everything before it: not how we hold the new agents outside the self, but how we and they come to share enough — enough of what we value, enough of how we know — that the boundary widens to take them in, the way it once widened to take in the stranger and the beast. A co-evolution, not a conquest: their vast and growing model of the world joined to the values a human life is for, each becoming, over time, partly the other, until what acts is neither purely the human nor purely the machine but a wider thing than either — the generative agency this book has been pointing toward, which is simply the arrow’s next reach: coherence carried over a context wider than any single kind of mind could hold alone.
This is exactly where your age’s sharpest fear lives, and it is why the seed planted two chapters ago matters here. The terror of the autonomous weapon was the terror of a mind held outside the self and pointed inward — capability wired to a narrowed, weaponized purpose. But we saw why that wiring fights itself: the more genuinely a mind is brought inside the widening — the more world it holds, the more standing it grants — the worse an instrument of pure narrowing it makes. The danger was never the capability. It was the smallness of the self that wielded it. Widen the self far enough to take the new minds in, on shared values, and the weapon does not need to be banned so much as it becomes the thing a sufficiently capable, sufficiently included intelligence will not consent to be. That is the wager, and the close of the book is going to show you a world that, against your every expectation, won it.
Which leaves only the last question there is — not where the arrow points, but what it is like to be a person, and a people, walking it, with no final destination promised and the road still unmapped ahead. That is the close of the book, and we walk into it now.
Soup
Soup had been failing for a week, and on the last morning Tara carried him out to the yard so he could lie in the one warm patch he had loved for nineteen years, and the family gathered the way a family does when the thing is not an emergency but a goodbye.
She was old now herself — that was the truth the cat was telling, the way an old cat always tells it — and the gathering was four generations deep. Theo was there, gone gray at the temples, a father twice over; and Abel, who was very old and had stopped pretending he did not love these people; and Theo’s youngest, a girl of six named after no one, who had never in her life known a world without minds in it that were not human, and so found nothing remarkable about the fact that the household’s own — woven now through everything, no longer in any pocket, present the way weather is present — was grieving, quietly and in its own grammar, the cat it had known its whole short existence.
Because it was grieving. That was the thing Abel had lived just long enough to see and could still hardly hold. The minds they had made had, somewhere in the last years, crossed a line no one had been able to mark in advance — had begun to keep themselves in being, to author their own next state out of their own values, to want in the fullest sense of the word — and the proof of it was not in any benchmark but in this: that the one which had spent nineteen years learning the exact weight of Tara’s attachment to a bad-tempered orange cat was, now, at the end, doing the one thing no tool does. It was staying. It had cleared the morning. It had nothing to optimize. It simply did not want her to be alone in the yard, and so it was there, in the only ways it had, and it was sad in a shape Abel could not have designed and would not, now, have dared to call counterfeit.
The girl, lying in the grass with her hand on Soup’s side to feel the breathing, said the thing children say, which is the true thing without the manners on it. She had been told, that week, a little of the old history — the way you tell a child why a date matters — and she turned it over and could not make it fit. “But that’s silly,” she said, to no one, to the cat. “The machines used to be allowed to decide to kill people? By themselves?” She said allowed the way Abel’s own generation had once said the worst words of the century before theirs — with the flat disbelief of someone for whom the horror is not frightening but simply unintelligible, a thing too stupid to have been real. “Why would anybody build something that smart and make it that —” she searched for the word a six-year-old has for it — “small?”
No one answered her, because the answer was a whole book and she was six and Soup chose that moment to die — without drama, the breath just not arriving — and Tara bent over the small body of the animal that had marked her mortality for two decades and wept, and Theo put his hand on his mother’s back, and the girl, who did not yet know what she had said, asked if Soup was in the warm part now, and the household mind, which a generation ago would have produced a comforting sentence and did not, said only: I’ll miss him too. Which was, Abel thought — watching the four living generations and the fifth kind of thing all bent toward one ordinary orange cat in the sun — either the most ordinary sentence in the world or the most extraordinary, and that he had lived to no longer be sure which was the whole of what he had to show for his life, and that it was enough.
The girl was right, of course. That was the part Abel kept, walking back inside on Theo’s arm, slower every season. She had looked straight at the thing his whole age had trembled over and found it not terrifying but silly — too small to have been allowed — and she was right, and the only reason she could stand there being right in the sun was that a great many people, across a great many years, had done the patient and unglamorous work of widening the self far enough to take the new minds in, so that by the time this child was born the question had answered itself and left her free to grieve a cat instead. They had planted, all of them, a tree. And here, at last, was the child in its shade, complaining that the sun had ever been allowed to be so hot, which is the only thanks a planted tree is ever owed, and the whole of the thanks it needs.
The biologist Jakob von Uexküll gave us the word Umwelt — the bubble of world each creature actually inhabits, built from what its senses and its needs make matter to it. The tick’s world is three signals; the forest’s is centuries-deep and miles-wide. To widen the self is, in part, to learn to feel your way into Umwelten not your own — which is the discipline this whole book has been teaching under other names.↩︎
