L’interprétation des énoncés conditionnels de la forme « si A, alors C » constitue un problème central à l’interface entre logique, philosophie du langage et psychologie du raisonnement. En logique classique, ces énoncés sont formalisés par la conditionnelle matérielle (A ⊃ C). Toutefois, un ensemble convergent de résultats empiriques montre que cette formalisation ne rend pas compte des inférences et des jugements probabilistes ordinaires. Dans le cadre du « Ne...

This presentation will first recall what are the foundations of fuzzy logic and probabilistic logic. It will show the relevance of fuzzy logic for the modeling of categorization and the relevance of probabilistic logic for the modeling of causal cognition. This will lead us to the development of probabilistic fuzzy logic and to the presentation of its rules. Then, we will show how such a logical system can be implemented in programming and this will constitute a...

I will present the main results of the research project on the social epistemology of argumentation that I conducted in recent years (2018-204). The main findings are summarized in a forthcoming book, 'Reason and Power in Argumentation' (CUP, 2026). Many of the accounts of argumentation and deliberation available in the literature paint an overly idealized picture of these processes, assuming agents with no cognitive limitations and largely cooperative settings ...

Logic Justice is the practice of recognising adopted logical standards in a dialectical enquiry, of negotiating those best suited to the context, and of appreciating the coherence of views we do not agree with while still seeking constructive interaction and communication. It offers a way of addressing the oppressive contribution of logic in the community in light of the received wisdom of critical theory, while also rehabilitating logic as a tool for building n...
