Formal Theories of Truth

In eight lectures I will provide an introduction to formal theories of truth.

The slides (at least some) for the lectures can be found here on WebLearn.

I shall start with an account of the diagonal lemma and the liar paradox. The
main emphasis of the lectures will be on developments after 1975, that is after
Kripke's *Outline of the Theory of Truth*. The relevance of the formal
results with respect to truth-theoretic deflationism will be discussed.

I intend to cover the following topics:

- The theory of sytax and diagonalisation
- Inconsistencies
- Disquotation
- Kripke's theory
- Axiomatisations of Kripke's theory
- Revision semantics
- Other axiomatic theories
- Truth and necessity
