CfP special issue of "Logical Investigations" on Negation

The journal "Logical Investigations" provides a platform for broad discussions of logical problems of both conceptual and purely theoretical nature. There are plans for a special issue of "Logical Investigations" devoted to logical and philosophical aspects of negation, Vol. 27(1), 2021.

Original papers are invited on negation related topics including but not limited to the following:

• negation as a modal operator
• contradictoriness and contrariety
• the interplay between negation and implication
• bilateralism (in proof-theoretic semantics)
• sentential negation versus term negation
• negationless theories
• negation inconsistent non-trivial logics
• negation, rejection, and denial
• negative information
• negation and disagreement
• demi-negation (double negation as negation)

Submissions should be written in English and should be submitted electronically as Pdf-documents generated from LaTeX using the style file LIarticle.cls which is available at https://logicalinvestigations.ru/public/journals/1/LI_template_eng.zip
(Final versions must be submitted as LaTeX source files.)

Papers should contain an abstract (200 to 250 words, preferably without references) and a list of keywords.

Submissions should include information about the author(s) first and last names; affiliation; full address of the place of work (including the postal code, country and city); authors' e-mail addresses.
