Theoretical linguistics postulates abstract structures that successfully explain key aspects of language. However, the precise relation between abstract theoretical ideas and empirical data from ...

Intuitionistic logic, i.e. logic without the principle of excluded middle (P ∨ ¬ P P \vee \neg P), is important for many reasons. One is that it arises naturally as the internal logic of toposes and ...
