Third Nordic Logic Summer School 2017Truth & ParadoxYou can find here my teaching materials for my course Truth & Paradox at the summer school. About the courseIn the five sessions I will provide an introduction to the paradoxes and formal theories of truth and other modal notions. The material should be accessible to anyone with a knowledge of the basics of firstorder logic; that is, participants should be familiar with a formal proof system such as Natural Deduction, a tableaux system, an axiomatic (Hilbert style) or sequent calculus. Knowledge of the semantics of firstorder predicate logic (definition of satisfaction in a model) and propositional modal logic is useful, but not required. In particular, I do not presuppose any knowledge of arithmetization and the Gödel incompleteness theorems. My presentation does not rely on the arithmetization of syntax theory. Instead I will present an axiomatic theory of syntax that will be explained in detail. Thereby I completely avoid the need to go through the difficult parts of the proof of Gödel's diagonal lemma. Topics to be covered include:
Here is a draft of my pdf slides (updated 5 August 2017). I realize that it will be impossible to cover the entire material in my lectures. I am happy to adapt my lectures to the preferences of the audience. Some of the material will appear in a book that I am coauthoring with Graham Leigh. The slides on axiomatic theories of truth are based on my monograph.
