The 4th International Conference on Logic and Argumentation (CLAR 2021) invites contributions from logic, artificial intelligence, philosophy, computer science, linguistics, law, and other areas studying logic and formal argumentation.

CLAR 2021 will be held in Hangzhou, 20-22 October 2021 at Zhejiang University City College. Due to the uncertainties of the epidemiological situation, the conference will be held in a HYBRID format (virtual and physical attendance both accepted), and we encourage physical participation if possible.

Papers accepted to CLAR 2021 will be published as Springer LNAI proceedings, and will be available online during the conference. Authors of selected papers will be invited to submit an extended version to a journal special issue after the conference.

The CLAR 2021 conference will highlight recent advances in logic and argumentation and foster interaction between these areas within and outside China. Previous conferences can be accessed via: https://www.zlaire.net/events/previous/clar
