Habermas's educational importance is usually misconstrued or underesti
mated, partly because the scope and implications of ideal speech condi
tions are generally misunderstood. These conditions are only relevant
to discursive speech situations, but non-manipulative teaching need no
t be discursive. And not even discursive teaching is an appropriate oc
casion for ideal speech conditions. They properly apply to discourse i
nstitutions, at the 'epistemic centre of modernity'. Thus, the concept
of ideal speech conditions impinges on the relation of school to high
er education and on curricular change as an agency of modernisation, a
nd illuminates the need for access to discourse institutions, if perso
nal autonomy is an aim for school children, students or adults. Neo-Ma
rxists, traditionalists and progressives all misunderstand the importa
nce of discourse institutions.
