Reasoning with conditionals: abduction and deduction by Serge RobertThis talk will present a model of causal cognition based on abductive reasoning. We will show how this kind of reasoning is systematically used in our cognition to establish causality, when we try to explain past events and predict future events. Contrary to what is usually held, our causal reasoning is not deductive, it is abductive and it is so because it relies mainly on our long-term mem...

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...
