"I Didn't Say That"

9.2 "I Didn't Say That"

Our age has gained a new kind of thing: a machine that can write speech. People call it artificial intelligence. Give it one instruction and it can write out a whole fluent essay; image and voice, too, can be synthesized out of nothing, lifelike past telling apart. Never has there been so much speech; never has speech been so hard to place. And so a sentence of unloaded responsibility has grown popular along with it—I didn't say that, the AI wrote it.

Does this sentence actually unload anything? To answer it, one must first return to the ancient scale of the precept against false speech, and see clearly what it is that the scale weighs.

The Dazhidu lun, judging how false speech is constituted, gathers it all into one sentence:

"False speech is: with an impure mind, wishing to deceive another, concealing the real, one utters words at variance—a verbal act arises… It arises from the hearer's comprehension of the sound of the words; if there is no comprehension, then though the words be untrue, there is no offense of false speech."

Take the sentence apart, and false speech requires four things complete: what is said runs contrary to what one knows (words at variance); there is the set purpose of deceiving (wishing to deceive another); it is spoken out plainly (a verbal act arises); and the other party understands it (comprehension). The most telling is the final turn: even if untrue words leave the mouth, if the hearer never understood them at all, there is "no offense of false speech"—the false speech is simply not constituted. So the condition that truly bears the weight on this scale is "wishing to deceive another"—that one thought set on deceiving, which the scriptures and treatises call the intent to deceive.

From this follows a corollary often overlooked: the evil of false speech does not hang on the truth or falsity of the sentence, but on that one thought of mind. A faulty memory, a slip of the tongue, a report passed on in sincere belief of what one was told—the words miss the fact, but the mind holds no intent to deceive, and the treatises plainly judge there is no offense. Conversely, a person may speak sentence after sentence of the literally true while every word is set on leading the hearer astray—and he stands not farther from breaking the precept, but nearer. The scale weighs the mind, not the truth-table of the words.

This is exactly the last chapter's "it is volition that is karma," come down onto the karma of speech. The treatises say that the sound of speech is only a face that volition shows outward: the one thought in the mind stirs first, and only then does the word leave the mouth—speech is volition's outward showing; volition is speech's root. So a false utterance presupposes a speaker who has volition. Ordinarily this layer hardly needs stating: the one who speaks is, of course, the one with a mind to speak. And just because "speech" and "the mind that issues the speech" fit together so naturally, we have never thought of them as two things that could be parted.

And the machine that writes speech has, for the first time, pried this joint open at scale. Pried it open into two ends.

One end is speech without volition. The machine can pour out speech in quantity—fluent, human-seeming, ample enough to be understood—but behind those words there is no thought of mind. The machine has no mind that can be defiled, so there is no speaking of an intent to deceive. By that scale, then, untrue words produced by a machine do not in themselves constitute false speech—to pin the offense of false speech on a mindless instrument is to pin it in the wrong place, just as a blade's sharpness cannot be judged a killing mind. False speech still requires a speaker who has volition; the machine is not that speaker.

The other end is volition that does not itself utter the speech. That one thought of the intent to deceive has not vanished—it has moved onto the person who uses the machine. The one set on deceiving need no longer say the sentence with his own mouth: the words are written for him, generated for him, issued for him by the machine. The mind is still there; the words have gone out; the deception has succeeded—yet that one thought of mind no longer adheres to the sentence that is heard. The volition that issues the speech and the speech that is heard have, for the first time, split into two places.

I didn't say that, the AI wrote it—this sentence is the spoken specimen of exactly this crack. The words were indeed produced and sent out on the strength of that one thought of mine; I have only hidden that one thought behind a thing that has no mind.

Here the most important point must be seen plainly: false speech is a natural precept. A natural precept means that the evil of the matter lies in the nature of the matter itself, not in whether the Buddha prescribed against it—even had no such precept ever been laid down in the world, the set purpose of deceiving would still be evil. (Its counterpart is called a proscribed precept—drinking, for instance, where the evil lies not in the nature of the act but in its readiness to give rise to faults, and so the Buddha proscribed it.) False speech being a natural precept, its moral substance hangs on the nature of that one intent to deceive—and that is a matter of the mind. What the machine can change is the instrument by which speech is issued; what it cannot erase is that one thought. To hand a deceiving sentence to a machine to write does not make the deceit in the mind vanish into thin air, nor does it make "working a deception by borrowing a mindless thing" cease to be deception. The medium can dilute the speech; it can wash away its origin; the one thing that cannot be weighed off the scale is the thought of volition that the natural precept weighs.

So the illness is not that the precept has lost its force—the precept has counted all along. The illness is in the owning: speech grows ever easier to send out, and those willing to turn back and own that one thought grow ever fewer.

Hold up a mirror in passing. "Volition present, the utterance left behind" has a reverse face, another shape: every word with its source, every sentence conforming to some format of "disclosure by the book," while the whole stretch of speech still quietly misleads. Watertight in form, the volition long gone from the truthful. This face and I didn't say that make an exact pair—the two illnesses of the last chapter, arrived at this gate of the karma of speech, are a pair here as well: one has dropped the form, one has dropped the heart.

And the medicine? The medicine is where it always was. The precept against false speech has its positive pole, called truthful speech, true speech—the Sūtra on the Ten Courses of Good Action says that when abstention from false speech is cultivated to its fullness, one "attains the true speech of the Tathāgata": at the time of becoming a Buddha, what one attains is the Buddha's speech of truth. A mind that does not deceive, issued as words, is truthful speech—this pole and false speech are the two ends, obverse and reverse, of one and the same scale. In daily use, that scale keeps only one question: this sentence I am sending out at this moment, by whoever's mouth, whoever's pen—is the one thought behind it still inside? Do I still own it?

The illnesses—two chapters have now seen them through. The medicine cabinet has been pointed out too—all of it in the earlier Parts of this book. But one sentence remains unsaid. That sentence, the Buddha left on the last night.
