Abstract for O'Hair's influential essay on "Implication"

"IN MANY CASES, UTTERANCES CONTAINING A CERTAIN WORD OFTEN OR USUALLY INVOLVE A CERTAIN IMPLICATION. IS THIS PART OF THE MEANING OF THE WORD? GRICE'S SUGGESTION THAT SUCH IMPLICATIONS ARE TO BE EXPLAINED AS DUE, NOT TO THE MEANING OF THE PARTICULAR WORD, BUT TO SOME GENERAL RULE GOVERNING CONVERSATION IS EXAMINED. GRICE'S TENTATIVE FORMULATION OF SUCH A RULE IS DISCUSSED, AND IT IS ARGUED THAT IT SHOULD BE REPLACED BY TWO SIGNIFICANTLY DIFFERENT RULES, ONE CONCERNED ONLY WITH THE CONTENT OF WHAT IS SAID, THE OTHER CONCERNED ALSO WITH THE WORDS UTTERED. SOME QUESTIONS CONCERNING THE STATUS OF SUCH RULES ARE INVESTIGATED BRIEFLY."
