Philosophy of set theory is not only of interest to those working in set theory, but also for people focused on more general philosophical questions. In the last few years, the field has experienced rapid development due to the emergence of many new set-theoretic results. It has therefore become quite difficult for the general philosophical audience to keep pace with these numerous developments and to integrate these new discoveries in broader philosophical investigations. This collection of chapters aims to tackle this situation by exploring how contemporary research into the philosophy of set theory interacts with philosophy more widely.
