Grice [Gabriel Debacker]

I agree with Grice that a sentence's implications can be completely different from what the words that make up the sentence might mean logically. A simple case of this is idioms, where something like "When the shit hits the fan" means 'when things start to happen/when things start to go wrong.'

I disagree that for a sentence to have meaning it must have intention from a speaker. Just as I agreed that a sentence's implications can be different from what the meanings of the words indicate, a sentence that, for example, is written on a wall can have meaning, and different meanings, with the only varying factor being the audience. If we strip language down to just words and sentences, without tone and other suprasegmental elements to indicate sarcasm and the like, I believe they can still hold meaning to someone who reads them.

Although Grice admits that everything we 'mean' does not fall into the categories he created, I'm curious if he considers things like double entendre in these other categories.
