Title: Second-Order Logic: If not Set Theory in Sheep’s Clothing, What is it Then?
Date: Wednesday 4 February 2026
Time: 15:00-16:30
Location: ILLC Seminar Room F1.15, Science Park 107
For this session of PhiMath, we read Bob Hale’s paper “Properties and the Interpretation of Second-Order Logic”. He defends a deflationary conception of properties, which are the things we quantify over in second order logic. According to Hale, something is a property iff there could be a predicate that stands for it.
