Trends in Logic XXI 2021 - Deadline Extension Announcement

-----
Updates and changes:

- Both online and on-site options for participation/presentation are planned
-----

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.

Modern connexive logic started in the 1960s with seminal papers by
Richard B. Angell and Storrs McCall. Connexive logics are orthogonal
to classical logic insofar as they validate certain non-theorems of
classical logic, namely

Aristotle's Theses: ~(~A => A), ~(A => ~A)
Boethius' Theses: (A => B)=> ~(A => ~B), (A => ~B) => ~(A => B)

Systems of connexive logic have been motivated by considerations on a
content connection between the antecedent and succedent of valid
implications and by applications that range from Aristotle's
syllogistic to Categorial Grammar and the study of causal
implications. Surveys of connexive logic can be found in:

S. McCall, "A History of Connexivity", in D.M. Gabbay et al. (eds.),
Handbook of the History of Logic. Volume 11. Logic: A History of its
Central Concepts, Amsterdam, Elsevier, 2012, pp. 415-449.

H. Wansing, "Connexive Logic", in Edward N. Zalta (ed.), The Stanford
Encyclopedia of Philosophy (Spring 2020 Edition).

There is also a special issue on connexive logics in the IfCoLog
Journal of Logics and their Applications based on papers presented
during the first workshop. The entire issue is available here.

There is another special issue of Logic and Logical Philosophy based
on papers presented during the third workshop. The entire issue is
available here.

As we are observing some growing interests in topics related to
connexive logics, after six annual workshops, the Trends in Logic XXI
aims at discussing directions for future research in connexive logics.

PAPER SUBMISSION:

Any papers related to connexive logics are welcome. Topics of interest
include (but are not limited to) the following:

- Historical considerations of the notion of connexivity;
- Discussions on the notion of connexive logics;
- Examinations of various systems of connexive logics;
- Relations between connexive logics and other nonclassical logics,
such as conditional logics;
- Philosophical implications of connexive logics;
- Discussions on the relation between Experimental philosophy and connexivity.

Moreover, we will have a special session on contra-classical logics,
and thus any papers related to contra-classical logics are welcome.
Topics of interest include (but are not limited to) the following:

- Historical considerations of contra-classical logics;
- Discussions on the notion of contra-classicality;
