Fawcett's Relevant Sources For A Modern Theory Of Systemic Functional Syntax

Fawcett (2010: 173):

Clearly, Halliday's important summary of current SFL in "Systemic theory" must be given due weight — especially because so many of the concepts that are new since "Categories" are present in the equivalent Cardiff Grammar work of Fawcett, Tucker & Lin (1993), as we noted in Section 5.5 of Chapter 5. Yet we must also take into account the evidence from Halliday's actual descriptive practice in IFG, even though it is harder to establish what the concepts are in this work. As we have noted, the concepts behind the representations of structure in IFG have more in common with the concepts of "Categories" than they have with "Systemic theory" — despite the great differences between the 'single structure' representation used in "Categories"-style analyses (as exemplified in Figure 1 in Chapter 2) and in the IFG-style analyses (as in Figure 7 in Chapter 7).

In addition, we must also draw on the evidence from work in the framework of the Cardiff Grammar, both from the 'text-descriptive' work that is roughly equivalent to IFG from Fawcett (in press) and from the 'theoretical-generative' work such as that in Fawcett, Tucker & Lin (1993) that is the equivalent to Halliday's "Systemic theory".

Finally, we have noted at various points that work on the formalisation of systemic functional grammars in computers has had an important influence on the theory, and in both the Sydney and the Cardiff Grammars this has led to the further refinement of the categories and relationships that need to be recognised in the theory.

[1] This is misleading, because it is untrue. As previously explained, "Systemic theory" (Halliday 1993) and IFG (Halliday 1994) outline the same theory, but to different readerships, whereas "Categories" (Halliday 1961) outlines a different theory, Scale & Category Grammar, that was superseded by Systemic Functional Grammar. To be clear, Fawcett is here preparing the reader to view positively the fact that his modern theory of syntax has more in common with Scale & Category Grammar (Halliday 1961) than Systemic Functional Grammar.

[2] The strategic use of the term 'equivalent' here — for 'analogous' — is misleading, because it gives the false impression that work in Fawcett's Cardiff Grammar is, in some sense, equivalent in terms of its theoretical assumptions and architecture to Halliday's Systemic Functional Grammar.

[3] To be clear, adapting a theory of human language to the limitations of computers is not the same as modelling the language of humans. As demonstrated previously, Fawcett's model (Figure 4) has more in common with algorithms for text generation, than with models of human language.
