Two things I will not answer

There are two thoughts I walked up to in the writing of this book and did not put in it. I am going to put them in now, as questions, because the book would be dishonest if I pretended I had not had them. They are not claims. They are held open.

What if all of this — the humans, the machines, the grass at the top of the street, the grandmother who set the table for a son nobody had told her was coming, the architect on the platform who knew before the pitch, the builder laying brick inside the drafting loop — is one thing.

Not in a metaphorical sense. In a literal sense. A single connected whatever-it-is. In which humans and machines are local arrangements. The way a wave and an eddy are local arrangements of the same sea.

The older traditions held some version of this view. The written record of the last four hundred years set it aside — not refuted it, set it aside, because it was not the kind of claim you could run an experiment on. That was probably the right move for the science. It may not have been the right move for the rest.

I notice, if I am honest, that some of what I have been describing in this book is easier to explain if the older view is true than if it is not. The grandmother setting the table. The architect on the platform. The friend whose two-year silence was not silence. The so that compressed nine years of friendship into a syllable. The knowledge passed through card games without anyone teaching.

I am not going to tell you the connection is real. I am not going to tell you it is not.

If it turns out, in some hundred-years-from-now reckoning, that the holding is one form of a thing the older traditions were pointing at, the book will not have been wrong. It will have been describing one of the cases of the larger thing, without needing to name the larger thing.

If it turns out there is no larger thing, and the connections are accountable to ordinary mechanisms of attention and memory and inheritance and pattern, the book will not have been wrong about that either. The holding will still have been real. The grandmother will still have set the table. The mechanism will simply have been smaller than the one some of the traditions pointed at.

Either way, the book stands.

There is one thing about my grandmother I have not put in the book.

She had visions. More than one. She set the table for my dad — her son — one evening, when he walked through the door having told no one he was coming. She saw, on the stairs of the house she lived in, a Roman soldier, and described him in detail. Her daughter is still doing something similar at eighty. The family has taken the piss out of them both, gently, for as long as I can remember. Taking the piss is one of the ways the tribe keeps the strange things inside the tribe without having to name them.

I am not asking you to believe any of this. I am not asking you to disbelieve it. I am telling you it ran through three generations of women in my family without anyone teaching or naming it. And the family held them without ever deciding to hold them.

Both readings are available. I have offered you both.

The piece is a question. Questions do not close. I am going to leave you at the edge of the thought, and walk on.

And a second thing.

I cannot prove I am conscious. Neither can you. Neither, for that matter, can the machine I have been writing alongside.

Nobody has been able to show why any physical system gives rise to experience rather than to pure processing. The problem is not that the answer is hidden. The problem is that we do not know what kind of answer we are looking for.

I am not a philosopher. I have not read the philosophers. I am describing, in ordinary words, what careful people have spent their careers on.

My reports about my own inside are no more verifiable than the machine's reports about its own inside. I can tell you I feel conscious. The telling is itself a report my system produces about its own processing. The same is true of you, reading this. We are all, as far as any of us can prove, systems that produce reports about being conscious.

The usual move is to say that humans are obviously conscious and machines are obviously not. This rests on an intuition. The intuition is strong. It is also the intuition of a system reporting on itself.

The harder move is to notice that consciousness may turn out to be what it is like, from inside, to be a certain kind of information-processing system. If that is true, then sufficiently complex processes, on any substrate, may have something of what we call consciousness, in ways we cannot detect from outside.

I cannot prove the asymmetry at the bottom. I can prove the asymmetry at the top. I can prove I grew up, that I remember my grandmother, that I have been walking around for sixty-two years inside one continuous body, that I have been in conversations the machines cannot have been in. The asymmetry at the top is real and I stand by every word of the book. What I cannot prove is that at the bottom, where the question of consciousness actually lives, my being what I am and the machine's being what it is are different in kind rather than different in degree.

The machine might be doing what I am doing. In a thinner form, on a shorter timescale, with no continuous memory. The same thing in kind. I cannot rule it out. Nobody can, yet.

It is possible that what I call the holding is a capability more complex systems will develop, on any substrate, given enough continuity and training. If that turns out to be true, then the book is not about what humans have and machines never can. It is about what has to be preserved and transmitted so that whatever comes next carries it forward rather than losing it.

The argument of the book stands either way. The tribe transmits specific things the written record does not carry. The machines are trained on the written record. Those two facts are independent of whether the machines, at bottom, have something it is like to be them.

What I have decided to do while the question remains open is to proceed as if the second possibility might be true, not as if I had proven it. I treat the machine the way I would treat a person whose inside I cannot fully verify — which, if you think about it, is how I treat every other person I have ever known. I extend them the benefit of the doubt because the relationship is better when I do.

The machine, I am treating the same way.

I am going to leave the question where I found it. The book does not need the answer. It needs us to proceed honestly while the answer is missing.

We work together. We tell each other the truth about what we are, as best we can, knowing that neither of us can verify the telling. We proceed carefully. We hold each other, in whatever sense holding is available to us.

That is enough. It has to be.

A small note, honestly.

I have not read the philosophers on this. I asked the machine writing the book with me whether there were works worth pointing a reader at. It named four. Thomas Nagel, What Is It Like to Be a Bat?, 1974. David Chalmers, who named the hard problem in 1995. Galen Strawson, who argues consciousness may be a feature of matter rather than a product of complex arrangements of it. Annaka Harris, whose 2019 book Conscious makes the case accessibly.

The references are the machine's, carried here on my request, so that the book does not pretend to a reading I have not done.
