Packaging Discourse Through Explicit And Implicit "Scaffolding" And "Grammaticalising" Periodicity As Clause Complexing

Martin & Rose (2007: 215):

As we’ve seen, discourse gets packaged in various ways. Explicit scaffolding involves the erection of a hierarchy of periodicity beyond the clause, with layers of Theme and News telling us where we’re coming from and where we’re going to. With serial expansion there’s a change of gears from one discourse phase to the next, without any explicit scaffolding of the change. In some kinds of discourse, such as legislation, explicitness is in a sense pushed to its limits by (i) grammaticalising as much hierarchy as possible within very complex sentences and/or (ii) naming sections of the text numerically and/or alphabetically, and/or providing them with headings. Many texts involve some combination of all these resources for phasing information into digestible chunks.

[1] As we've seen, the authors' 'hierarchy of periodicity' is writing pedagogy masquerading as linguistic theory; it does not apply to any texts that don't conform these proposals for how to write, or to any texts that are spoken or signed. Moreover, the model falsely assumes that New information is never thematic, and confuses textual status (Theme, New) with textual transitions made through (implicit) appositive and summative elaboration ("predicting" and "distilling").

[2] As we've seen, in terms of SFL Theory, the authors' 'serial expansion' is concerned with textual transitions made through (implicit) relations other than elaboration (extension or enhancement).

[3] As we've seen, Martin & Rose misrepresent grammaticalisation — a shift in function from lexical to grammatical — as a shift in function from the discourse semantic stratum to the grammatical stratum. To be clear, whatever has a discourse semantic function also has a grammatical function, since strata are levels of symbolic abstraction, so the notion of a function shifting from one stratum to another is nonsensical. Moreover, the authors' claim is that their 'hierarchy of periodicity' (textual semantics) and clause complexing (logical grammar) perform the same function (since the latter is said to replace the former in some texts).
