In sensu non in situ: the prodromic cognitivism of Kussmaul

Kussmaul's model of language functions is presented, together with antecedent models that have influenced his conception of linguistic processes. The particular interest in this model lies in the fact that it anticipates the modern approach to diagram-making. In contrast to most of his contemporaries, Kussmaul understood that a functional model can, indeed ought to, be developed without being constrained by considerations of localization, as long as the neurological foundations of language remain underspecified. He thus deserves recognition as a pioneer of cognitive neuropsychology.
