The logic of propositions is first presented, which is the one introduced by Aristotle and which reigned for two thousand years. Next, the logic of predicates is exposed, which imposed itself at the ...

There is no linear order in propositional and lexico-syntactic structure. As mentioned above we will put the head and predicate first, and the arguments after it: ...

Do representational pictures have propositional contents? The current paper argues that the characteristic contents of pictures are predicative rather than propositional: pictures characterize things ...

This chapter contains sections titled: 4.1 Propositional Logic, 4.2 What Does It Mean to Be Constructive?, 4.3 First-Order Logic, 4.4 Predicates with Implicit Equality, 4.5 Recursive Predicates ...

We study predicate logic that is interpreted in Kripke models similarly to intuitionistic logic except that the accessibility relation of each model is not necessarily reflexive. Unlike in ...
