5th Workshop on Connexive Logics

After four workshops on connexive logics in Istanbul (June 2015), Raesfeld
Castle (June 2016), Kyoto (September 2017) and Bochum (October 2018), a
fifth workshop on connexive logics will take place in Bochum (Germany) on
the 29th of November, 2019. The workshop will be collocated with a workshop
on the Logic of Paradox, from the 25th to 27th, and a workshop on FDE-based
modal logic on the 28th.

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:

Handbook of the History of Logic. Volume 11. Logic: A History of its
Central Concepts, Amsterdam, Elsevier, 2012, pp. 415-449.

Encyclopedia of Philosophy (Fall 2014 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 at:

https://urldefense.proofpoint.com/v2/url?u=http-3A__www.collegepublications.co.uk_journals_ifcolog_-3F00007&d=DwIBaQ&c=slrrB7dE8n7gBJbeO0g-IQ&r=xXZM6ZrkjVxXknjzIxhAvQ&m=DbuusjtgAoqrKVYwKEFGufrDt-4AukQLuViEs537_MM&s=a96vaGA_ink-wI6GiKTwo_ADBbcLwUslTpree0p7K7A&e= 

There is another special issue of Logic and Logical Philosophy in
preparation based on papers presented during the third workshop.

As we are observing some growing interests in topics related to connexive
logics, the fifth workshop aims at discussing directions for future
research in connexive logics. Special focus will be given on historical
aspects as well as connections to conditional logics.

Keynote speakers (in alphabetical order):

Vincenzo Crupi
Andrea Iacona
Spencer Johnston
Marko Malink

Organisers:
The workshop is organised by Hitoshi Omori (Ruhr University Bochum,
Germany) and Heinrich Wansing (Ruhr University 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;
- 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.

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

Hitoshi.Omori at rub.de and heinrich.wansing at rub.de.

Deadline for submission: October 15, 2019.
Notification of acceptance: October 31, 2019.
