Misrepresenting Axis As the Origin Of Metafunction And Rank

[1] This gloss of the metafunctions is potentially misleading. The ideation metafunction is the construal of experience, not the construal of discourse, and the interpersonal metafunction is the enactment of interpersonal relations, not the enactment of discourse. Halliday & Matthiessen (1999: 7-8):

The ideational metafunction is concerned with construing experience — it is language as a theory of reality, as a resource for reflecting on the world. … The interpersonal metafunction is concerned with enacting interpersonal relations through language, with the adoption and assignment of speech roles, with the negotiation of attitudes, and so on — it is language in the praxis of intersubjectivity, as a resource for interacting with others. The textual metafunction is an enabling one; it is concerned with organising ideational and interpersonal meaning as discourse — as meaning that is contextualised and shared.

[2] The claim that 'SFL's distinctive approach to meaning and constituency in fact grew out of the development of axis (system/structure relations) from the early 1960s' is very misleading because it is untrue on several counts.

Firstly, Martin misunderstands axis as system/structure relations, as stipulated in realisation statements. In SFL Theory, axis is a local dimension whose two orders are the paradigmatic and syntagmatic (Halliday & Matthiessen 2014: 32), with system and structure as their respective dimensions. Realisation statements are located on the paradigmatic axis, and as the name suggests, the relation between the axes is simply realisation.

Secondly, the SFL approach to the metafunctions and constituency did not grow out of the development of either axis or system/structure relations from the early 1960's. 

On the one hand, the metafunctions are a distinct global dimension from the local dimension of axis (ibid.), and first appeared in Language Structure and Language Function (Halliday 1970). 

On the other hand, the SFL approach to constituency, a rank scale, is a distinct local dimension  from the local dimension of axis (Halliday & Matthiessen 2014: 32), and derives from the method of ranked constituency analysis, rather than immediate constituency analysis, as first set out in Categories of A Theory of Grammar (Halliday 1961), and explained more fully in Introduction to Functional Grammar (Halliday 1985).

The rhetorical significance of Martin's misleading bare assertion (the ipse dixit fallacy) is that it assumes the conclusion (the petitio principii fallacy) of the entire monograph. That is, it is one logical fallacy serving another in an invalid argument for a false conclusion.
