3rd Workshop on Connexive Logics

After two workshops on connexive logics in Istanbul (June 2015) and
Raesfeld Castle (June 2016), a third workshop on connexive logics will take
place in Kyoto (Japan) as part of “Kyoto Nonclassical Logic Workshop III”,
7th of September 2017.


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,

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).

There is also a special issue on connexive logics in the IfCoLog Journal of
Logics and their Applications. The entire issue is available at:


This workshop is meant to present current work on connexive logic and to
stimulate future research.

Keynote speakers:
Norihiro Kamide (Teikyo University, Japan)
Andreas Kapsner (LMU Munich, Germany)

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

Call for abstracts:

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
- Arguments for or against connexive logics
- Examinations of systems of connexive logics
- non-explosiveness of logical consequence

Submissions of extended abstracts (up to five pages) should be sent to both
organizers as a pdf file at

hitoshiomori at gmail.com and heinrich.wansing at rub.de.

Deadline for submission: June 30th 2017.
Notification of acceptance: July 7th 2017.
