Degrees and Domains of Consistency
Consistency is a gradable property. It can range from the minimal — simply not being inconsistent — to being in harmony, all the way to being wholly consistent. Models may vary in their degree of internal consistency and in how well they fit with other models within a given domain of categorisation.
The “truth” of a model lies in the degree to which it fits other models — not as an absolute state, but as a matter of alignment across systems of meaning. This fit is always scoped: the scope of consistency may be narrow and local, or broad and global.
For instance:
-
Ideational construals may be consistent within or across fields of knowledge, tenors of interaction, or modes of expression.
-
Interpersonal values may be consistent within or across these same dimensions — fields, tenors, and modes.
-
Textual saliences — what is foregrounded or backgrounded — may likewise be consistent within or across fields, tenors, and modes.
Each of these axes offers a different plane along which consistency (and inconsistency) can be tracked and evaluated.
This book is, in part, an attempt to establish some degree of ideational consistency across fields.
