I would like to announce the KEOD’s Special Session (this year in Vilamoura, Portugal) devoted to formal and non-formal aspects of nonmonotonicity. Strict applying of the definition of nonmonotonic inference shows that many examples for nonmonotonicity of human thinking as well as constructions, traditionally understood as nonmonotonic have nothing common with the negation of well known Tarski’s condition for monotonic operation. A rejection from nonmonotonic interpretation of those examples and constructions opens new perspectives in researches on human thinking.
