Three Planes of Temporal Meaning
According to Halliday, grammar construes time along three distinct yet interwoven planes of reality:
-
Experiential time: time as a feature of processes—when something happened, how long it lasted, or how often it recurs. This is the grammar of locating events in some real or imagined history.
-
Interpersonal time: time as a stance between speaker and listener. Tense here enacts a relation to the speaker-now, while usuality (always, often, never) negotiates expectation across a scale of arguability.
-
Textual time: time as constructed by and within the unfolding discourse. “Then,” for instance, may position events in an external chronology—or serve to order the phases of the text itself.
Witnessing traverses all three planes. It draws on experiential time to recount what happened, on interpersonal time to frame how it matters now, and on textual time to organise its telling as a meaningful act in the present.
Witnessing and Temporal Agency
A witness is not just a speaker in time, but a speaker of time. The grammar of witnessing positions the speaker temporally:
-
As then-there in the experiential event;
-
As now-here in the act of telling;
-
And as always-responsible across time, through the ethical force of what is said and unsaid.
Different grammatical choices invoke different temporal agencies. Consider these shifts:
-
Experiential: “He was shot.” vs. “They shot him.”
-
Interpersonal: “It’s always been like this.” vs. “I’m telling you now—this matters.”
-
Textual: “Then he ran.” vs. “Now—this is where everything changed.”
Each construes time differently: as a scene of process, a negotiation of stance, or a progression of discourse.
The Grammar of Testimony and Its Stakes
Grammar does not merely record temporal sequences; it enacts relationships of accountability. A witness must choose:
-
Tense: to temporalise the event in relation to the now.
-
Aspect: to highlight completion, continuation, or interruption.
-
Voice: to show or hide agency.
-
Usuality: to frame the event as exceptional, typical, or systemic.
-
Phase: to textualise the telling—when to withhold, when to disclose.
These are not neutral decisions. They shape whether a witness is seen as credible, whether the event is seen as closed or open-ended, and whether the audience is invited to sympathise, judge, or ignore.
Witness, Trace, and Temporal Re-instantiation
To witness is to instantiate an experience that could otherwise remain latent in memory, archive, or trauma. But unlike mere trace-reinstantiation, witnessing also positions that instance in time: as a now that must bear the weight of a then.
AI can generate temporally plausible sequences—construing experiential, interpersonal, and textual time in grammar. But it cannot occupy any of them. It temporalises without temporal being. Its meanings are structurally coherent but ontologically hollow.
That’s why it is vital to distinguish between temporal patterning and temporal presence. A witness is present in time not only grammatically, but ethically.
Temporal Authorship and Discursive Risk
Temporalities of witnessing always carry risk. Speak too soon and the story may be disbelieved. Speak too late and its relevance may have passed. The scene of telling is thus charged with temporality as both condition and gamble.
In legal, political, and poetic discourses, this risk is shaped by genre expectations and power. Testimony in a courtroom must align its phases to a procedural temporality. Memoir bends narrative time to experiential truth. Protest slogans collapse time: “Still here.” “No more.”
These are not just ways of telling, but of claiming temporal authority.
Conclusion: Witnessing as Metafunctional Timework
Witnessing is a highly metafunctional act. It construes:
-
What happened (experientially),
-
How it matters now (interpersonally),
-
And how it is to be taken up (textually).
AI can simulate this timework, but it cannot live it. It can produce traces of witness—but not the witness of the trace.
In an era of synthetic tellings, we must become more alert to the semiotic planes of temporality. We must listen for the human configurations of time that carry not only information, but responsibility. For it is in these tensions—between trace and presence, sequence and stance, grammar and accountability—that the true temporality of witnessing lives.
