Eugenio Moya cites Grice in abstract to his essay

"Recanati holds that, in the contextualism vs. anticontextualism debate, the latter view has received more support than the former thanks to an argument that can be placed in some of Grice's writings. Such an argument has the 'parallelism principle' as a premise, a principle that, Recanati argues, makes the argument circular and the contextualist position unjustified. Although I consider this anticontextualist argument unjustified, I will show that it cannot be attributed to Grice. By considering his explanation of certain examples and his theory of implicatura, I will show that Grice does not admit the parallelism principle. This reveals Grice to be a contextualist."
