Skepticism and Mathematics
摘要
Model-theoretic skepticism is a challenge to purported a priori mathematical knowledge. According to this challenge, elementary results from mathematical logic undermine our grasp of basic mathematical concepts such as finitude and countability. Despite generating rich discussion over the years, most philosophers don’t feel worried by model-theoretic skepticism, in part due to a number of notable anti-skeptical arguments. In this paper, I evaluate these arguments, and explore the question of whether (and to what extent) a skeptical threat remains.
