## Department: Philosophy

### PHIL3201: FORMAL AND PHILOSOPHICAL LOGIC

Type | Open | Level | 3 | Credits | 20 | Availability | Available in 2016/17 | Module Cap | Location | Durham |
---|

#### Prerequisites

- Introduction to Logic (PHIL1031), Mathematics for Computer Science (COMP1021), Theory of Computation (COMP2181), or other appropriate evidence

#### Corequisites

- None

#### Excluded Combination of Modules

- None

#### Aims

- To introduce students to philosophical important issues connected to formal logic, including a subset of the following: non-classical logics, such as modal logic and relevance logic; the developments in early 20th-century logic (stemming from Hilbertâ€™s programme) leading to GÃ¶delâ€™s proofs of the completeness of first-order logic and the incompleteness of Peano Arithmetic; axiomatizations of set theory, including the independence of the Axiom of Choice and the Continuum Hypothesis; different approaches to philosophy of mathematics and the foundations of mathematics.
- To provide them with the technical means necessary to prove these results for themselves.
- Aimed at: Students in Philosophy, Mathematics, and Computer Science.

#### Content

- Kripke models for propositional modal logic.
- Axiomatic proof systems for propositional modal logic
- Theoretical and philosophical issues related to quantified modal logic
- Proof systems for first-order logic
- Model theory for first-order logic
- A brief history of Hilbertâ€™s problems and the context of GÃ¶delâ€™s theorems
- Completeness Theorems for first-order logic
- Peano Arithmetic and proof by mathematical induction
- Incompleteness Theorems for Peano Arithmetic
- Axiomatizations of set theory
- The independence of the Axiom of Choice and the Continuum Hypothesis
- Platonist, Intuitionist, Formalist, and Structuralists Philosophies of Mathematics

#### Learning Outcomes

Subject-specific Knowledge:

- At the end of the module students should have a grasp of the philosophical significance of various developments in logic and mathematics, such as completeness and incompleteness phenomena; the historical context in which these issues first arose, and the relevant proof and model theory for proving the necessary technical results.

Subject-specific Skills:

- By the end of the module students should be able to do a selection of the following:
- Prove completeness and canonicity of specific propositional modal logics
- Prove correspondence results between properties of models and specific modal axioms.
- Prove theorems of first-order logic using mathematical induction
- Prove the completeness theorem for first-order logic
- Understand independence results in set theory and logic
- Articulate the differences between different foundational approaches to logic and mathematics.

Key Skills:

- Students will be:
- Able to write formal logic proofs in a clear, rigorious style.
- Able to articulate in a clear and concise fashion the historical and philosophical aspects of the material covered.
- Adequately prepared to go on to do further research in formal logic at master's level.

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

- This module will be taught in weekly two-hour seminars, with regular homework assignments and seminar presentations allowing the students to practice the technical skills they are being taught. Teaching and learning methods will support students in achieving the Subject-Specific Skills above. The Subject-Specific Skills will be formally assessed by the end of year exam.
