Picturing Thought

On AI writing detectors, Plato's Phaedrus, and what Monet knew when photography came for painting.

Lately, on podcast after podcast, I hear a certain glee in the sport of detecting AI-generated prose. The tells get catalogued like contraband: the em-dash, the tidy triad, the word "delve." Case in point: the recent Wall Street Journal op-ed whose author openly used AI to help write his piece. What surprised people — and unsettled some — was not the confession but the backing he received from the editors of that venerable newspaper for his unabashed stance.

The outrage is revealing. I think it signals that we are being forced, for the first time, to make a distinction we never had to make before the emergence of large language models: the distinction between language, speech, and writing. For as long as any of us have been alive, the three traveled together so closely that we could treat them as one thing. A piece of writing was assumed to be the trace of a particular person's speech, which was in turn the trace of that person's thought. AI-assisted writing breaks the chain, and the detectors' glee is really an anxiety about what the written artifact still testifies to.

Speech Is Older Than Writing

But we put the cart before the horse when we forget that speech is far older than writing. Writing is not language; it is a technology applied to language — an instrument, and a young one at that. The human mind spent eons in the symbolic nursery of vast oral traditions before a single mark was pressed into clay. Everything we call literacy — outlining, drafting, revising, the essay itself — is a set of learned methods for using that instrument as a tool of thought.

So as our symbolic capability undergoes a fundamental shift — and I believe that is what is happening now with LLMs — writing, and the methods we have all internalized for thinking with it, will have to change too. That is not a catastrophe; it is what technologies of thought do.

We Have Been Here Before

Here we are in danger of becoming despondent prematurely. The history of philosophy has been through this before. In Plato's Phaedrus, Socrates weighs the worth of writing itself against speech and finds it wanting: written words, he warns, are orphans that cannot defend themselves, and reliance on them will produce the appearance of wisdom without the reality. Every anxiety now aimed at AI-generated text was once aimed at text. And yet writing did not destroy thought; it gave thought a new medium, and eventually a new depth. The oral traditions were not erased so much as absorbed.

Monet's Serenity

My feeling is that we ought to recapture some of the sublime serenity Claude Monet showed when he was told that a photograph could make a better picture. Photography did not end painting; it freed painting from the burden of mere depiction and pushed it toward what only painting could do — toward impression, toward light, toward the picturing of perception itself. The detectors are scrutinizing brushstrokes for evidence of a camera. Monet, one imagines, would have smiled and kept painting.
