Analyticity is one of those philosophical notions that are intuitively too vague to be easily explicable in an unambiguous way. The trouble with this notion seems to be related to the fact that there is hardly anything that would be analytic or synthetic in some absolute sense. Rather, analyticity is relative to the conceptual framework (logic, theory, language, etc.) used. For instance, a truth or argument which could be counted analytic (by some criterion) in some logic may not even be a logical truth or acceptable argument within another logic." /> Surface information and analyticity - Rantala Veikko | sdvig press
