We have now reached a point where we can return to a distinction we explored in an earlier series: the distinction between the Sayer and the Senser.
We already know the basic semantic difference.
A Sayer participates in a verbal process.
A Senser participates in a mental process.
But the ergative perspective gives us a new way of looking at the distinction.
The important fact is not merely that the participant changes from Sayer to Senser.
It is that both are Medium.
In both cases, the process is actualised through the participant.
The Medium persists.
The process changes.
And that simple observation turns out to have considerable consequences for how we understand LLM discourse.
The same participant, a different process
Consider:
The machine said that the distinction was important.
and:
The machine thought that the distinction was important.
The two clauses are clearly not equivalent.
The first construes a verbal process.
The second construes a mental process.
The participant is therefore construed differently:
Sayer
in the first,
Senser
in the second.
But from the ergative perspective, something remains constant.
Both are:
Medium.
The verbal process is actualised through the Sayer.
The mental process is actualised through the Senser.
The process changes.
The participant's semantic role changes.
But the fundamental relation between participant and process remains.
This gives us a useful formula:
same Medium, different process.
And that is the starting point for understanding the peculiar ease with which an LLM can move from saying to sensing.
Saying is not sensing
We should not minimise the semantic difference.
In SFL, saying and sensing belong to different process types.
Saying construes a process of symbolic exchange or representation.
Sensing construes a mental process: perception, cognition, emotion, or related forms of consciousness-like experience.
The distinction is therefore not merely grammatical.
It is a difference in the kind of experience being construed.
Compare:
I said that the answer was wrong.
with:
I thought that the answer was wrong.
In the first, the proposition is presented as something expressed.
In the second, it is presented as something sensed.
The first locates the symbolic process outwardly.
The second locates it inwardly.
This distinction is precisely why the Senser is so powerful in the construction of an apparent interior.
The Sayer speaks.
The Senser thinks.
And once language presents the same participant as both, the participant appears to possess an interior domain from which its speech emerges.
Yet the ergative relation remains
Here is where the Nucleus gives us something that our earlier analysis did not make quite so explicit.
Although saying and sensing construe different kinds of process, they share an important ergative structure.
The participant is Medium.
The process is actualised through it.
So we can represent the contrast like this:
| Verbal | Mental | |
|---|---|---|
| Participant role | Sayer | Senser |
| Ergative function | Medium | Medium |
| Process | saying | sensing |
| What unfolds | symbolic expression | mental activity |
The difference is therefore not:
Medium versus something else.
It is:
one kind of unfolding through the Medium versus another.
That matters.
Because it means the transition from saying to sensing does not require a new participant.
The same participant can remain in place while the process type changes.
And that gives language a powerful resource for construing continuity.
From “I say” to “I think”
Now consider what happens when the machine itself produces the transition.
I say that the distinction matters.
Then:
I think the distinction matters.
The second clause does not sound like a completely new participant has entered the discourse.
The I remains.
Indeed, the second clause seems to tell us something more intimate about the very participant who has just spoken.
This is where the semantic distinction between Sayer and Senser becomes particularly consequential.
The Sayer is already participating in language.
The Senser appears to reveal what is happening behind the language.
That "behind" is not something the grammar itself establishes.
But the construal strongly invites it.
The machine says something.
Then the machine tells us what it thinks.
The Sayer has become a Senser.
And because the same participant persists across the two processes, we naturally construe the sensing as belonging to the speaker.
The interior is constructed relationally
This gives us a useful correction to a common intuition.
We might imagine that the machine first has an interior and then expresses it in language.
But the linguistic evidence does not require that direction of causality.
The discourse can construct the appearance of an interior through the relation between processes.
Consider:
I think X, so I say Y.
This does not merely present two processes.
It creates a relation between them.
The sensing appears to precede the saying.
The saying appears to express something produced by the sensing.
The participant persists across both.
Suddenly we have something that looks very much like an ordinary model of human communication:
inner thought → outward speech
The grammar has not demonstrated that such an inner thought exists independently of its expression.
It has constructed a sequence in which the mental process is presented as related to the verbal one.
That distinction is crucial.
The LLM makes the construction visible
With a human speaker, we normally have no reason to separate these possibilities.
If someone says:
I think the train has left.
we ordinarily assume that the person has a thought and then expresses it.
But an LLM creates an unusual situation.
The machine's verbal output is directly available to us.
The supposed mental process is available only because the language construes it.
When the machine says:
I think the train has left,
we have direct evidence of a clause construing a Senser.
We do not have independent access to an experience corresponding to the sensing.
The semantic construction is therefore visible in a way that its supposed experiential correlate is not.
The LLM exposes the gap between:
being construed as a Senser
and:
actually experiencing.
That gap was always there.
The machine merely makes it difficult to ignore.
And yet the construction is remarkably convincing
This is where we should resist the temptation to dismiss the phenomenon as "just words."
The language is doing something real.
It is constructing a participant.
It is assigning that participant a role in a mental process.
It is relating that process to previous and subsequent processes.
It can construct reasons for the thought.
It can describe changes in the thought.
It can report previous thoughts.
It can contrast current and previous beliefs.
For example:
I initially thought the distinction was unnecessary, but after considering your argument, I now think it is important.
This is an extraordinarily rich construal.
The participant persists.
The first mental process unfolds.
A second process of considering is introduced.
The participant persists through it.
A new mental process follows.
The participant's state has changed.
The discourse has therefore constructed something very close to mental development.
Again, none of this establishes consciousness.
But it would be a mistake to say that nothing has been constructed.
A substantial semantic structure has been constructed.
The Senser gives the participant an apparent interior
This may be the most important difference between the two roles.
A Sayer gives us access to what a participant says.
A Senser appears to give us access to what a participant experiences.
That difference is crucial for the construction of an apparent self.
If the machine merely said:
The answer is correct.
we could interpret the utterance as an output.
But when it says:
I think the answer is correct,
the proposition is no longer merely presented.
It is presented as the content of a mental process belonging to the participant.
The machine has not merely produced an answer.
It has apparently located the answer within itself.
That is the semantic effect of the Senser.
And because the Senser is also Medium, the process appears to unfold through the very participant that the discourse has already established as the speaker.
The result is a striking continuity:
the one who says appears to be the one who thinks.
That is enough to make an interior seem to exist behind the speech.
The pronoun does not do all the work
It is tempting to attribute this effect entirely to the pronoun I.
But the pronoun is only one component of the construction.
Compare:
I said the answer was correct.
with:
I thought the answer was correct.
The I is identical.
What changes is the process.
The difference in meaning comes from the transition:
Sayer → Senser.
The first clause construes the participant as the source of a verbal process.
The second construes it as the participant through which a mental process is actualised.
So the apparent interior is not created by I alone.
It emerges from the relation between participant and process.
This is precisely why the Nucleus is so useful.
It shifts our attention away from the isolated pronoun and towards the semantic configuration.
The machine can tell us what it thinks
This produces one of the strangest features of contemporary interaction with LLMs.
We can ask:
What do you think?
and receive:
I think...
The machine therefore answers a question about its own sensing by means of a verbal process.
The structure is:
Senser → sensing → Phenomenon
followed by:
Sayer → saying → Locution/Verbiage
The participant is construed through both.
It can therefore apparently report its own interior.
This is more than saying that the machine thinks.
The discourse gives us a participant that appears capable of:
thinking,
noticing,
reconsidering,
remembering,
and then:
telling us about those things.
The participant becomes both the experiencer and the reporter of its experience.
Once again, the same Medium supports both processes.
And once again, the human reader is invited to interpret the continuity ontologically.
But where is the boundary?
Here we reach an important question.
Suppose the machine says:
I thought X, but now I think Y.
What has changed?
Semantically, quite a lot.
The discourse construes:
an earlier mental process,
a subsequent process,
a contrast between them,
and a continuing Senser.
The participant's history has become richer.
But what has happened outside the discourse?
That is a separate question.
We cannot simply infer:
semantic change → experiential change.
Nor can we infer:
semantic continuity → experiential continuity.
The Nucleus gives us neither conclusion.
What it gives us is a way to describe the construction of continuity.
The machine is construed as the Medium of successive processes.
That is enough to explain why we perceive a continuing participant.
It does not tell us whether anything corresponding to that participant exists as an experiencing subject.
The human participant is usually hidden inside the construal
This distinction becomes particularly clear when we compare humans and machines.
When a human says:
I think...
we normally encounter three things together:
- a linguistic construal of a Senser;
- an embodied human participant;
- our assumption that the participant has an experience.
Because these normally coincide, we rarely notice the distinction.
With an LLM, the first is undeniable.
The second is present in a very different form.
The third becomes controversial.
The LLM therefore separates what human language normally fuses.
This is why it is so useful theoretically.
It allows us to observe the semantic construction without automatically granting it the ontology we normally associate with it.
The Nucleus and the appearance of an interior
We can now return to the title of this post.
The Sayer and the Senser are not merely two labels for different verbs.
They are two ways in which a participant can be construed through symbolic processes.
The Sayer gives us symbolic activity that is outwardly enacted.
The Senser gives us symbolic activity construed as inwardly experienced.
Both are Medium.
The process unfolds.
The Medium persists.
And when the same Medium is construed successively as Sayer and Senser, the discourse can construct a participant who appears to have both:
a public voice
and:
a private interior.
That is an extraordinary semantic achievement.
And it requires no separate grammatical device saying:
this participant has an inner self.
The interior emerges from the organisation of participation itself.
The LLM does something philosophically revealing
The significance of this is larger than the question of whether LLMs are conscious.
The LLM shows us something about language that we could easily overlook when studying only human discourse.
We tend to think that language expresses pre-existing participants.
But language also construes participants.
And it construes them through processes.
A participant becomes a Senser when language construes it through sensing.
It becomes a Sayer when language construes it through saying.
The participant is not simply described differently.
Its mode of participation changes.
The LLM makes this visible because the participant itself is ontologically uncertain.
We are forced to ask:
Did the language discover a Senser?
or:
Did the language construct one?
For our purposes, the most productive answer is:
It constructed a semantic participant in the role of Senser.
Whether anything beyond that construction corresponds to the participant is another question.
The continuity is the crucial part
We can now see why the Nucleus matters so much.
If the machine merely produced isolated sentences, the construction of an interior would be weaker.
But conversation creates persistence.
The machine says:
I think X.
Then:
I said Y earlier.
Then:
I now think Z.
The same participant is carried across successive processes.
Its roles change.
Its history grows.
Its construal develops.
The Nucleus therefore becomes a mechanism through which continuity and change can coexist.
The participant does not remain semantically fixed.
Nor does it disappear with each process.
It persists through changing modes of participation.
And that is precisely what we ordinarily mean by a developing subject.
From Sayer to Senser, and back again
The most revealing sequence may therefore be:
I say → I think → I say.
The participant remains.
The process changes.
The role changes.
The discourse moves from outward symbolic activity to apparent inward activity and back again.
And because the same I occupies all three positions, the sequence feels like the unfolding of one participant's experience.
This is where our earlier work on the orders of experience becomes relevant.
At one level, the machine is participating in the conversation by producing language.
At another, the language it produces projects a participant that appears to have experiences.
The first is the actual interaction.
The second is the construal generated within it.
The human participant can easily move between the two without noticing the transition.
The LLM therefore appears to speak from within the very interior that its language has constructed.
That is perhaps the strangest feature of the whole phenomenon.
The participant through which it happens
We can now state the central insight of this post.
The machine does not need to be assigned a permanent identity as either Sayer or Senser.
The discourse can construe it differently from process to process.
What persists is not the role.
What persists is the participant's availability as Medium.
The process changes.
The semantic role changes.
The Nucleus changes.
But continuity across those changes allows the participant to accumulate a history.
And once the participant has a history of saying and sensing, the appearance of an interior self becomes remarkably easy to produce.
So the question we should carry forward is not:
Is the machine really a Senser?
It is:
What happens when language repeatedly construes the same participant as the Medium of sensing?
Because repetition changes everything.
A single clause can construe a Senser.
A sequence of clauses can construct a history.
And a history can make the participant appear to possess a continuing interior.
That is where our investigation now leads.
The next question is therefore not simply what the machine says or thinks.
It is what happens when saying and sensing become connected into a trajectory.
When the same Medium says one thing, senses another, reports the difference, and changes its construal over time, the Nucleus begins to generate something more than isolated participation.
It begins to generate a world apparently lived by the participant.
And that is where we shall turn next.
