Philosophie des modalités épistémiques : la logique assertorique revisitée

Abstract : The relevance of any logical analysis lies in its ability to solve paradoxes and trace conceptual troubles back ; with this respect, the task of epistemic logic is to handle paradoxes in connection with the concept of knowledge. Epistemic logic is currently introduced as the logical analysis of crucial concepts within epistemology, namely : knowledge, belief, truth, and justification. An alternative approach will be advanced here in order to enlighten such a discourse, as centred upon the word assertion and displayed in terms of utterance. Insofar as epistemic modalities express some attitudes, the intentionality of discourse will be emphasized within an illocutionary modal logic. Two large views will range over the whole study : declarative and epistemic sentences have one and the same logic (assertion logic) ; the plurality of languages games doesn't entail any logical pluralism.
