Logic II : Metatheory (PH210-15)

TIMING & CATS

This module runs in the Autumn Term and is worth 15 CATS.

MODULE DESCRIPTIONPublish

This module will develop the metatheory of propositional and first-order logic. The primary goal is to show that a proof system similar to that of Logic I is sound (i.e. proves only logically true sentences) and complete (proves all logically true sentences). In order to better understand how we prove things about (as opposed to within) a proof system, we will first study elementary set theory and inductive definitions. We will then consider Tarski's definitions of satisfaction and truth in a model and proceed to develop the Henkin completeness proof for first-order logic. Other topics covered along the way will include Russell's Paradox, countable versus uncountable sets, the compactness theorem and the expressive limitations of first-order logic.

LEARNING OUTCOMES OR AIMS

By the end of the module the student should be able to: 1) demonstrate knowledge of the Soundness and Completeness Theorems for propositional and first-order logic and related technical results and definitions; 2) understand the significance these concepts and results have for logic and mathematics; 3) use and define concepts with precision with precision, both within formal and discursive contexts.

BACKGROUND READING AND TEXTBOOKS

Our primary text will be

- Logic and Structure, 4th edition by Dirk van Dalen, Springer Verlag, 2004

in which we will cover most of chapters 1-3. The same material is also covered at a more elementary level in chapters 15-19 of

- Language, Proof and Logic, Jon Barwise and John Etchemendy, CSLI Publications, 2002.

Students lacking a background in elementary discrete maths (e.g. basic set theory and mathematical induction) are encouraged to obtain

- Prove It: A Structured Approach, Daniel J. Velleman, Cambridge University Press, 2006.

Maths students considering taking further logic courses might consider getting a copy of

- The Mathematics of Logic, Richard Kaye, Cambridge University Press, 2007.
