The expertise, for example, supporting
a particular claim, may be an important factor, or ‘ground’ (Habermas,
1984a) in its argumentative force or validity, particularly when it
comes to persuading a universal audience, therefore a link may need
to be explicit for ideal speech to be better approximated. It is therefore
through this rather formal triadic framework, based on Habermas
(1984a) that we seek to identify different ways in which the EPIC scenario
planning approximated or fell significantly short of ideal speech.
