Instantiation Is Not a Process

In systemic functional linguistics (SFL), instantiation is often casually described as “the process by which a system becomes a text.” This formulation, however, is both misleading and philosophically precarious. Once we examine it through a relational-ontological lens, it becomes clear that instantiation is not a process at all—it is a perspectival relation between potential and instance within a stratum.

1. Canonical Halliday: System and Instance

In Halliday’s framework:

• System = a structured potential, a network of possible choices, never a physical or temporal entity.

• Instance = a particular construal of that potential, such as a text (language) or a situation (context).

Crucially:

System is potential, instance is actualisation.

Nothing “moves” from one to the other, and nothing unfolds in time simply by virtue of being instantiated.

Instantiation does not cross strata. A text is an instance of the content potential of language, not of context. Similarly, a situation is an instance of contextual potential, not of language. Each plane has its own potential–instance relation.

2. Why Instantiation Is Not a Process

Text generation studies, particularly Matthiessen’s work on logogenesis, have framed instantiation as a temporal process:

• The system “exists” beforehand.

• The text “draws from” the system.

• Choices are “made” in a sequence, flowing from potential to instance.

This historical framing originates in computational and text-generation contexts, where it was convenient to treat system selection as sequential. However, this reflects algorithmic modelling requirements, not Halliday’s canonical ontology. Treating instantiation as a process outside these contexts introduces conceptual confusion.

Conceptually, instantiation is atemporal and perspectival:

1. System is not temporally prior. The potential exists as a relational cut, not a stored precondition.

2. Instance is not produced. It is a perspectival actualisation: an event construed as an instance of a system.

3. No literal unfolding occurs. “Sequence” is explanatory or procedural; the theoretical relation itself remains atemporal.

---

3. Instantiation as Perspectival Relation

Instead of a process, instantiation is:

• Token–type relation within a stratum:

  • Context → situation

  • Semantic potential → text

• A perspectival cut: The observer construes an instance as an actualisation of potential.

This formulation preserves the canonical stratification and respects the independence of potential and actualisation.

4. Distinguishing Instantiation from Semogenesis

Halliday identifies three major time-frames of semogenesis:

1. Phylogenetic: Evolution of human language; species-level potential

2. Ontogenetic: Individual development of semiotic potential

3. Logogenetic: Actualisation of meaning in the act of producing or interpreting a text

Semogenesis describes temporal unfolding of meaning, but it is not the same as instantiation. Instantiation remains atemporal, stratum-bound, and perspectival, while semogenesis describes how instances occur within human time, interact, and accumulate.

Including semogenesis clarifies that temporal processes exist in meaning-making, but they are orthogonal to the ontological relation of potential to instance. This resolves the confusion introduced when instantiation is mistakenly treated as a process.

---

5. Implications for SFL Theory

1. No cross-stratal instantiation: A text cannot be an instance of context; register cannot instantiate situation types.

2. Preserves the purity of strata: System networks, semantic potential, lexicogrammar, and phonology remain distinct.

3. Clears up common misconceptions: Logogenetic generation, semantic drift, and “realisation pipelines” are explanatory aids, not ontological facts.

4. Grounds relational ontology: System = theory of possible instances; instance = perspectival actualisation; construal = constitutive.

---

6. Conclusion

Instantiation is a relational cut, not a process.

Understanding it in this way aligns SFL with relational ontology, keeps the canonical architecture intact, and prevents the category errors and representational slippage that have proliferated in derivative models.

Once we accept that instantiation is atemporal, perspectival, and stratum-bound, and that semogenesis describes temporal unfolding of meaning separately, the architecture of SFL becomes both conceptually cleaner and philosophically coherent.

A Close Examination Of David Rose's 2023 SFLIG Plenary Abstract

Plenary 3: Cultures, Texts and People: Challenges Of Change In SFL Practice 

Dr David Rose, University of Sydney 

Abstract: 

Thanks to Jay Lemke, SFL has a model for interpreting change at three time scales, named for us by Michael Halliday as phylogenesis for the evolution of semiotic systems, ontogenesis for the growth of persons, and logogenesis for the unfolding of texts. Jim Martin has associated these scales of change with three hierachies [sic] in our model of semiosis. Phylogenesis is associated with the hierachy [sic] of realisation, between evolving systems at the strata of genre, register, discourse, grammar and phonology. Ontogenesis is associated with the cline of individuation, from personae to groups, communities and master identities. Logogenesis is associated with the instantiation cline, from systems to text types to texts to readings. 

Perhaps most relevant to the research themes of this conference are clines of individuation - how communities affiliate around issues of environment, governance and conflict, how semiotic repertoires are allocated by institutions such as education and healthcare, and now how to characterise the place of AI in semiotic communities. For SFL researchers, variations in affiliation and allocation are found by comparing patterns instantiated in texts. A difficult question is how to grapple with this complexity in our data and our arguments. 

The traditional practice of listing features with clause examples falters beyond systems of grammar and phonology. One alternative is to leave linguistic analysis for statistics, mining texts for clause or item types and counting their frequencies. Another is to interpret data discursively with loosely defined topologies. But if our goal is changing practices in these fields, we need to be able to show how systems are instantiated and individuated at each semiotic stratum, in ways that will be useful for non-specialists. For me, that means hanging on to texts, and presenting them in novel formats that foreground the patterns we are concerned with. These formats must also be economical for the analyst, and concise enough for publication. In this talk I will illustrate some processes for designing analyses, that couple multiple perspectives on texts, while keeping them intact.

[1] As the term suggests, 'ontogenesis' is the coming into being of the system (in the individual).

[2] This is very misleading indeed. This was not Martin's innovation but Halliday's model. For example, Halliday & Matthiessen (1999: 18):

[3] This is misleading. Phylogenesis is the evolution of the system — meaning potential — in the species, whereas realisation is merely the relation of symbolic abstraction that obtains between system and structure and between strata. Phylogenesis involves change in all dimensions of language, for example, change within the systems of semantics, lexicogrammar and phonology, change in the structures of semantics, lexicogrammar and phonology, change in the instantiation probabilities of semantics, lexicogrammar and phonology.

[4] To be clear, these are Martin's strata, all of which are proposed on the basis of theoretical misunderstandings, as demonstrated in great detail here. For example, Martin's genre misconstrues text type and the semantic structures of various text types as non-linguistic context. Martin's register misconstrues functional varieties of language as the non-linguistic context that are realised by such varieties. Martin's 'discourse' is primarily his rebranding of Halliday & Hasan's lexicogrammatical cohesion as his discourse semantics.

[5] To be clear, this has Martin's cline of individuation backwards. Individuation is the process by which an individual becomes distinct. But see further below.

[6] This misunderstands the cline of instantiation. Texts are instances of a speaker's meaning potential, whereas readings are addressees' interpretation of such texts.

[7] This misunderstands the cline of individuation. The organising principle of individuation, like instantiation, is elaboration (hyponymy). Moving down the cline is viewing the elaboration of types. The organising principle of affiliation, on the other hand, is extension (meronymy). Affiliation is concerned with the groups that individuals associate with. This confusion explains why Rose described Martin's cline from the bottom up, instead of the top down.

[8] Clearly, there are no clause features in phonology.

[9] To be clear, in SFL Theory, statistics are the means of distinguishing varieties on the cline of instantiation. Viewed from the system pole, varieties differ in terms of the instantiation probabilities of features; viewed from the instance pole, varieties differ in terms of the instantiation frequencies of features.

[10] To be clear, "hanging on to texts" should go without saying in SFL. Halliday (2003[1994]: 437):

… systemic theory gives prominence to discourse, or 'text'; not — or not only — as evidence for the system, but valued, rather, as constitutive of the culture.

Premature Articulation

As a rule, the man who first thinks of a new idea is so much ahead of his time that everyone thinks him silly, so that he remains obscure and is soon forgotten.  Then, gradually, the world becomes ready for his idea, and the man who proclaims it at the fortunate moment gets all the credit.

The Dead Hand Of Plato In Formal Linguistics

Genuine change, according to essentialism, is possible only through the saltational origin of new essences.  Because evolution, as explained by Darwin, is by necessity gradual, it is quite incompatible with essentialism.

Did Neanderthals Contribute To Sapiens Languages?

Neanderthals may have talked -- even contributed to our languages, scholars claim:

Surprising proposals come on the heels of findings that Neanderthals interbred with ancestors of modern humans.

The Significance Of Phylogenetic Stratification Of The Content Plane

Halliday & Matthiessen (2004: 25):

The stratification of the content plane had immense significance in the evolution of the human species — it is not an exaggeration to say that it turned Homo … into Homo sapiens. It opened up the power of language and in so doing created the modern human brain.
