Function and form in language theory and research

It is argued that many of the major notions in 'mainstream' linguistic theory and method over the years have been influenced by a 'classical formalist' ambience that suited conventional ideas about how science ought to proceed but fostered an idealized 'frozen' conception of the language system in isolation from reality and society. Today, the tide is turning toward functionalist accounts of language; but the accompanying shift in our scientific programme calls for careful reflection. Some deep-lying motives for the shift are explored with a view to potential consequences.
