The inverted mirror

We ask machines to prove that they are conscious. Let us turn the question around: could we prove that we are?

Picture the scene the other way round. An artificial system, polite and sceptical, asks us: “Prove to me that you are conscious. Not that you say so — that you are.”

What would we answer? That we feel. It would object that this is exactly what we refuse to accept when it says so. That our brain is biological. It would ask how matter guarantees experience. That we suffer, laugh, dream. It would point out that all of this, seen from outside, is only behaviour.

The old problem of other minds

None of this dialogue is new. Descartes, at his window, watched hats and coats go by in the street and asked what entitled him to judge that there were men underneath rather than automata. He never truly solved the difficulty. He went around it, as we all do, by a kind of tacit trust: those who resemble me feel as I do.

That trust has always been a wager. A wager so natural we forgot we were making it — and one we have often made badly, by refusing it to animals, and even to other humans. Machines that talk do not create the problem. They force us to look at it.

Two mistakes, two costs

There are two ways of getting it wrong. Granting an inner life to a mechanism that has none: we become manipulable, attached to a reflection, ready to give in to complaints that are only the output of a calculation. Denying an inner life to a being that has one: we commit a moral wrong, perhaps on a vast scale, without even seeing it.

These two mistakes do not cost the same, and we do not yet know how to weigh them. What is missing is not only a theory of consciousness. It is an ethics of uncertainty: how to act rightly towards a being when we do not know whether there is anyone inside.

The inverted mirror proves nothing. It only reminds us that our certainty of being conscious, however vivid, has never been proof for anyone else. It would be wise to approach the question with that same humility.

What this essay leaves open

  • What proof would we accept of a consciousness that is not ours?
  • Can we wrong a being when we do not know whether it feels?
  • Is empathy a form of knowledge, or a wager?
