As a rule of thumb, one should always be on guard when a neologism pops up. The neologism is supposed to announce a new idea, a breakthrough that most of us are blessed with perhaps once in a lifetime. But it usually covers for an old idea, tarted up and raring to go. Julia Kristeva is known to do this, with terms like 'semanalyse' and 'intertextuality', as is Mr. Foucault with his 'governmentality' and 'biopower'. The tell-tale sign: no reference to anyone else's work.
