S. addresses problems of the following type: why is 'Sam is approximately six feet tall' a worse approximation of the truth if Sam is 5'8" tall than 'That cockroach is approximately six feet tall' if the cockroach is in reality 5'8" tall? He claims that a pragmatic account is more explanatory than an account in terms of fuzzy semantics. It seems to be the conversational purpose of an estimate that essentially determines how close to the truth it must be to be a 'good' estimate.
