Its thought is based on what is wrong (the variant being a form of deviant behaviour), and it is the basis for a positive methodology", was criticised by the Indologist Reinhold GrĂĽnendahl, who argued that the aim of Cerquiglini's work is not to contribution to a methodological debate but to confirm the premise of critical theory.Currently, he is in charge the Center for French and Francophone Studies in the Louisiana State University in Baton Rouge, Louisiana.
