Trends in Logic is the conference series of the journal Studia Logica (see also here).

The 21st Trends in Logic international conference will be held at Ruhr University Bochum, Germany, from December 6-December 8, 2021 under the title “Frontiers of connexive logic”. It is organized by the chairs of Logic and Epistemology and Nonclassical Logic at the Department of Philosophy I of Ruhr University Bochum, in co-operation with Studia Logica.

Studia Logica was founded in 1953 by Kazimierz Ajdukiewicz, one of the prominent representatives of the Lvov-Warsaw School, who aimed to promote research embodying the main idea of the School, namely to apply mathematical methods to important philosophical problems. Since its very first issue, Studia Logica has joined the forces of mathematicians and philosophers in carrying out logical investigations. The success of the Lvov-Warsaw School united philosophy and mathematics in novel and deep ways. The papers published in Studia Logica have testified to the fact that the School's thought not only has not gone out of date but still remains a weighty source of inspiration for those who approach philosophical problems by means of formal methods.

Trends in Logic XXI has been supported by Alexander von Humboldt Stiftung/Foundation.

[UPDATES on 31.08.21] The conference is now planned in a hybrid format, allowing online presentation/participation. Note also that the deadline for the submission of abstracts is extended by two weeks.
