During World War II Bakhtin submitted a dissertation on the French Renaissance writer Francois Rabelais which was not defended until some years later. The controversial ideas discussed within the work caused much disagreement, and it was consequently decided that Bakhtin be denied his higher doctorate. Thus, due to its content, Rabelais and Folk Culture of the Middle Ages and Renaissance was not published until 1965, at which time it was given the title Rabelais and His World (Russian: Tvorchestvo Fransua Rable i narodnaia kul'tura srednevekov'ia i Renessansa, Tvorcestvo Fransua Rable i narodnaja kul'tura srednevekov'ja i Renessansa).  In Rabelais and His World, a classic of Renaissance studies, Bakhtin concerns himself with the openness of Gargantua and Pantagruel; however, the book itself also serves as an example of such openness. Throughout the text, Bakhtin attempts two things: he seeks to recover sections of Gargantua and Pantagruel that, in the past, were either ignored or suppressed, and conducts an analysis of the Renaissance social system in order to discover the balance between language that was permitted and language that was not. It is by means of this analysis that Bakhtin pinpoints two important subtexts: the first is carnival (carnivalesque) which Bakhtin describes as a social institution, and the second is grotesque realism which is defined as a literary mode. Thus, in Rabelais and His World Bakhtin studies the interaction between the social and the literary, as well as the meaning of the body and the material bodily lower stratum.  In his chapter on the history of laughter, Bakhtin advances the notion of its therapeutic and liberating force, arguing that "laughing truth ... degraded power".
