Introductory description

Do mathematical objects such as numbers and sets exist or are they merely useful fictions? What is the nature of mathematical knowledge and how is it distinct from our knowledge of the physical world? What, if any, is the connection between the two? What role does mathematics play in the empirical sciences? What is the correct logic for reasoning about mathematics? Are formally undecidable statements (e.g. the Parallel Postulate, the Gödel sentence, the Continuum Hypothesis) objectively true or false? This module will explore different ways in which philosophy might be of help in answering these questions, both from the contemporary perspective and that of the major foundational schools of the late nineteen and early twentieth centuries -- i.e. logicism, intuitionism, and formalism.

Module aims

This module has two goals:

  1. to familiarise students with major developments in the foundations of mathematics from the late 19th century onward;
  2. to illustrate how these developments inform contemporary debates in philosophy of mathematics.
Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

Learning outcomes

By the end of the module, students should be able to:

  • Demonstrate knowledge of some of the central topics in the philosophy of mathematics, and of the historical development of key approaches to the philosophy of mathematics (Subject knowledge and understanding)
  • Understand the significance questions in the philosophy of mathematics have to wider issues in philosophy and the foundations of mathematics (cognitive skills)
  • Articulate their own view of the relative merits of different theories and engage critically with the arguments put forward in support of them (key skills)
  • Show an understanding of methodological issues in the philosophy of mathematics, and of questions of demarcation between philosophy and mathematics (subject-specific skills)
Indicative reading list

Our primary texts will be

  • Thinking about mathematics, Stewart Shapiro, Oxford University Press, 2000.
  • Philosophies of mathematics, Alexander George and David Velleman, Wiley-Blackwell, 2001.
    Many of the other reading are available in
  • Philosophy of Mathematics: Selected Readings edited by Paul Benacerraf and Hilary Putnam,
    Cambridge University Press, 1983. [BP]
  • The Stanford Encyclopedia of Philosophy [SEP].
    Other sources are available through the Moodle page.
Subject specific skills

Show an understanding of methodological issues in the philosophy of mathematics, and of questions of demarcation between philosophy and mathematics

Transferable skills

Understand how major debates in the philosophy of mathematics -- e.g. between logicism, formalism, and intuitionism -- are related to topics in the history of philosophy, metaphysics, and epistemology. Appreciate how developments in mathematical logic -- e.g. axiomatic set theory, proof theory -- grew out of concern for foundational issues in the 19th and early 20th century.

Pre-requisites

PH136 (Logic 1) is recommended as a prerequisite. Otherwise, the module is designed to be as
self-contained as possible. But you should be aware that several of the topics we will discuss are
related to developments in mathematical logic (as treated in modules like Logic II/III and Set
Theory) and also build on philosophical themes which are covered in modules like Metaphysics
and Epistemology. So background in these subjects will be helpful for fully engaging with the
module content.
