Breaking the spell: Waismann's papers on the analytic/synthetic distinction

This paper explores, develops, and evaluates Waismann’s six papers on the analytic/synthetic distinction, which were published in Analysis between 1949 and 1953. Although the sequence is unfinished, Waismann develops a view of analyticity on which it can be defined in terms of definitions. Definitions, however, are a diverse group of things which cannot be given a definition themselves. Much like a family resemblance expression, definitions are irregular, incomplete, and their extensions are subject to our choices. Analyticity—being defined in terms of definitions—inherits these properties. Given the foundational importance of analyticity in the linguistic approach to philosophy popular at the time Waismann was writing, the view turns out to have far-reaching consequences for Positivism, for Ordinary Language Philosophy, for the epistemology of logic, and for the way we pursue philosophy.
