This work analyses the speech-act of arguing as proposed by Linguistic Normative Model of Argumentation (LNMA) with the help of diagrams, examples and basic formalization techniques. The focus is set on one of the most novel issues of LNMA, modal qualification, and the distinction between epistemic and ontological modals. The first conclusion is that employing LNMA in order to analyse and evaluate actual argumentation as it is proposed is too complex to be applied as is. The second conclusion, at a (...) theoretical level, is that the distinction between ontological and epistemic modals is highly problematic in LNMA. (shrink)

When a speaker states an argument in arguing—in its core sense—for the conclusion, the speaker asserts, as opposed to merely implies or implicates, the associated inference claim to the effect that the conclusion follows from the premises. In defense of this, I argue that how an inference claim is conveyed when stating an argument is constrained by constitutive and normative conditions for core cases of the speech of arguing for a conclusion. The speech act of assertion better reflects such conditions (...) than does implication, conversational implicature, or conventional implicature. (shrink)

A conclusion follows from given premisses if and only if an acceptable counterfactual-supporting covering generalization of the argument rules out, either definitively or with some modal qualification, simultaneous acceptability of the premisses and non-accepta-bility of the conclusion, even though it does not rule out acceptability of the premisses and does not require acceptability of the conclusion independently of the premisses. Hence the reiterative associated conditional of an argument is true if and only it has such a covering generalization, and a (...) supposed unexpressed premiss supplied to make an argument formally valid should be a covering generalization.
