Foregrounding, as I understand it, is prominence that is motivated - Michael Halliday

The grammatical system has … a functional input and a structural output; it provides the mechanism for different functions to be combined in one utterance

Any text in spoken English is organized into what may be called 'information units'. (...) this is not determined (...) by constituent structure. Rather could it be said that the distribution of information specifies a distinct structure on a different plan. (...) Information structure is realized phonologically by 'tonality', the distribution of the text into tone groups.

The human sciences have to assume at least an equal responsibility in establishing the foundations of knowledge.
