- Discuss Cantor's notion of set, its axiomatization in ZFC, and the role of set theory as a foundation for mathematics.
- Asses the extent to which Frege succeeded in establishing his claim that the truths of arithmetic were analytic.
- Can Mathematics be naturalized? Should we want it to be? In your answer, make explicit reference to Nominalism.
- Intuitionism in Mathematics and Logic: Explicate and Assess.
- What is Structuralism and is it defensible?
- How should we distinguish predicative functions from impredicative functions?
- Is higher-order logic truly logic, and is second-order logic distinct from set-theory?
