Fawcett's Higher 'Rhetorical Structure Relations' Component

Fawcett (2010: 331-2, 332n):

However, M&M can still point out that the question remains of where, in the overall model, we should express the similarity between (1a) and (3a). My answer is that the place to handle the choice that is realised by these examples is in a higher component of the generation process than the lexicogrammar. This is the component which plans the rhetorical structure relations of the discourse, and so how best to present the relations between any two events. (For the key proposals for this component see Mann and Thompson 1987, and for a useful introductory discussion see Martin 1992.) Indeed, the choice that is realised in (1a), (2a) or (3a) must also be extended to include a realisation such as (4), so that for this reason too it is appropriate to handle it outside the lexicogrammar.¹⁸

(4) He left the room. Then they voted.

¹⁸ In fact, it is also at this stage in generation that the planner needs to consider choosing other conceptually equivalent choices realised in forms which M&M do not mention but which express the same basic temporal relationship of successivity between events, such as They voted after he left the room and After he left the room they voted.

Reminder:

(1a) He left the room before they voted.

(2a) He left the room before the vote.

(3a) He left the room, then they voted.

[1] To be clear, in SFL Theory, the distinction between (1a) and (3a) is the distinction between hypotaxis and parataxis at the rank of clause, and it modelled in the grammar by the system of clause complexing. Halliday & Matthiessen (2014: 438):

[2] To be clear, Fawcett does not locate this higher component anywhere in the architecture of his model (Figures 4 and 12):

[3] To be clear, Martin (1992: 251-64) misunderstands Rhetorical Structure Theory.  See, for example, the clarifying critiques here, here, and here.

[4] To be clear, in SFL Theory, these are all different grammatical manifestations of the enhancement category 'time: different':

• in (1a), it is realised logically through clause complexing: hypotaxis;
• in (2a) it is realised experientially through clause transitivity: circumstantiation;
• in (3a), it is realised logically through clause complexing: parataxis; and
• in (4), it is realised textually through cohesive conjunction.

[5] To be clear, in SFL Theory, the logico-semantic relation between the clauses in both of these hypotactic complexes is analysed as 'time: different: later', with the first complex ordered dominant^dependent (α^β), and the second ordered dependent^dominant (β^α). Note again that Fawcett frames this in terms of a model of text generation by computers, rather than a model of language spoken or written by humans.
