Author’s Abstract

    According to Michael Dummett, deductive inference stands in need of justification which must be provided by the theory of meaning for natural language. Such a theory, he insists, should deliver an explanation for the two essential features of deduction: validity and fruitfulness. Dummett claims that only a molecularist theory of meaning could offer the desired justification. In this paper, I will consider and criticize his solution to the problem of the justification of deduction: the so-called molecular verificationist explanation. My aim here will be to show that Dummett’s solution does not succeed in reconciling the conflicting demands of the respective explanations of validity and fruitfulness.
