The Universality of Hegel, As Dismissed by Grice

In "The Universality of Conversational Postulates" (in Kasher, "Implicature", Routledge) Elinor Ochs Keenan, argues that the Gricean theory is not universal. The author presents her
findings that the inhabitants of a small village in
Madagascar violate systematically the maxim of Quantity -
they give too less information. Kasher (in a postscipt
from 1982 to his paper) suggests that these findings
could be explained by an interaction between his
(universal) rationality principle and local cultural
practices.
