Grice's not going to Hawaii not wearing a hat.

PPQ, vol. 67, p. 22.

Davidson fails to maximise negation.

"I do not interrupt my children's chatter."

"I ignore the conversational intrusions of my neighbour."

"I omit the first paragraph of a letter I read aloud."

"I hold my fire when the rabbit emerges from the burrow."

--- These are actions, yet not for Davidson.

"I do not sign exemptions from penalties."


---- "Davidson is forced into the admission of
NEGATIVE events, with ONE entity filling the 'event
slot' if on a particular occasion I go to Hawaii
(or wear a hat) and ANOTHER entity filling that
slot if on that occasion I do NOT go to Hawaii
(or do NOT wear a hat)."

Genial!
