See for example the conclusion of André Le Gall in the most recent biography of Corneille (Flammarion, 1997): 'It is not inconceivable that Molière entrusted his manuscripts to Corneille so that he could take a look at them. [This hypothesis, which is purely hypothetical, but in keeping with the nature of the links that can be forged between an author and his director, does not in any way detract from Molière's authorship of his works. (p. 473); see also, in 2011, the protest issued by the community of Corneille specialists: http://www.corneille.org/index.php? lng=en
See for example the conclusion of Roger Duchêne in his biography of Molière (Fayard, 1998): "Faced with this web of inventions, approximations and errors that convince only those who love sensationalism and let themselves be carried away by the imagination and eloquence of a writer of novels, one remains confused when one sees that the idea continues to make its way and to find defenders over time." (p. 162); see also in 2011 the site "Molière auteur des œuvres de Molière" opened by those responsible for the new edition of Molière's Œuvres complètes in the Bibliothèque de la Pléiade published in 2010.
