19 - 21 October 2018, 4th Workshop on Connexive Logics, Bochum, Germany

Date: 19 - 21 October 2018
Location: Bochum, Germany
Deadline: Sunday 15 July 2018

After three workshops on connexive logics in Istanbul (June 2015), Raesfeld Castle (June 2016) and Kyoto (September 2017), a fourth workshop on connexive logics will take place in Bochum (Germany) as part of “Logic in Bochum IV” from 19th to 21st of October, 2018.

Description:

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 (Fall 2014 Edition). http://plato.stanford.edu/archives/fall2014/entries/logic-connexive/.

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 at:
http://www.collegepublications.co.uk/journals/ifcolog/?00007

There is another special issue in preparation based on papers presented during the third workshop.

As we are observing some growing interests in topics related to connexive logics, the fourth workshop aims at discussing directions for future research in connexive logics. Moreover, we will have a special session on contra-classical logics, namely a broad family of nonclassical logics, including connexive logics, that are orthogonal to classical logic.

Keynote speakers (in alphabetical order):

John Cantwell
Paul Egré
Luis Estrada-González
Nissim Francez
Andreas Kapsner
Wolfgang Lenzen
Francesco Paoli
Niki Pfeifer
Claudio Pizzi

Organisers:

The workshop is organised by Hitoshi Omori (Japan Advanced Institute of Science and Technology, Japan) and Heinrich Wansing (Ruhr University of Bochum, Germany).

Call for abstracts:

Any papers related to connexive logics, as well as contra-classical 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 and contra-classical logics;
- Relations between connexive logics and other nonclassical logics, such as conditional logics;
- Philosophical implications of connexive logics and contra-classical logics;
- Discussions on the relation between Experimental philosophy and connexivity.

Submissions of extended abstracts (up to five pages) should be sent to both organizers as a pdf file, to Hitoshi Omori at and Heinrich Wansing at .

Deadline for submission: July 15, 2018. Notification of acceptance: July 31, 2018.
