[1] Here again Martin & Rose confuse
context (field) with
language (clause functions). In SFL theory,
field is the ideational dimension of
context (the instantiation cline from
culture to
situation). In contrast, the ergative functions of Process, Medium, Agent and Beneficiary are features of
language:
semantic distinctions that are realised in the
grammar of the clause. That is, the authors confuse what's going on, culturally, in the creation of text, with what's going on in the text itself.
[2] To be clear, relations between elements of
clause structure are
grammatical relations,
not lexical relations.
[3] To be clear, the claims here are that:
- the relation between the centre (Process) and itself is elaboration (=);
- the relation between the centre (Process) and the nucleus (Medium) is extension (+);
- the relation between the centre (Process) and the margin (Agent or Beneficiary) is enhancement (x).
Only the last of these three claims demonstrates an understanding of Halliday's model. Of the first claim, it will be seen later here that Martin & Rose also include
Range: process within the centre — though they also include intensive and possessive Attributes such as
(be) an Englishman and
(have) the guts, while, at the same time, excluding intensive and possessive Attributes such as
(going) mad and
(had) another lover.
Of the second claim, the notion that the Medium
extends (adds to) the Process is inconsistent with the definition of the Medium as the participant through which the Process is actualised. In Halliday's original model, the Process and Medium together form the experiential Nucleus of the clause.
[4] To be clear, relations between Processes of different clauses are neither
lexical relations, nor nuclear relations
within the clause. Moreover, in the examples provided, the relation between
applying for and
(not) giving is
not one of elaboration, since the relation is
not one of
partial identity: i.e. one does
not restate or clarify the other.
[5] Here again Martin & Rose misconstrue the
realisation relation between
two levels of symbolic abstraction,
context (field) and
language (processes), as one of
composition ('parts of') at the
same level.
[6] To be clear, the authors' schema of "lexical" relations not only misunderstands Halliday's ergative model but misapplies it to the data, misinterpreting the
Medium (
police officers, the Commission) as
Agent, and misinterpreting the
Range (
amnesty) as
Medium. This can be made explicit by comparing the authors' analysis:
