Presentation 

In human language and cognition, words and concepts are basic units of meaning that we combine to form more complex meanings. While some combinations are simple juxtapositions – as in ‘The weather is nice. It's cold.’ – others are based on deeper, non-trivial mechanisms of composition. Thus, a sentence such as ‘The weather is not nice’ cannot be reduced to the simple addition of ‘The weather is nice’ and its negation.

This presentation proposes to rethink the nature of this non-trivial composition of meaning, based on a renewed formal approach at the crossroads of linguistics, logic and cognitive science.
