Topic areas



The notion of assertion plays a key inferential role and has a long tradition in logic. It is a key ingredient in most logical systems, either implicitly or explicitly.

The idea of assertion thus appears strongly invariant across a range of logical theories, logical methods, and logical notations such as Frege’s Begriffsschrift, Heyting’s formalization of intuitionistic logic or Charles S. Peirce’s Existential Graphs just to mention some examples.

Aim of the workshop is to bring together scholars interested in the analysis of the logical notion of assertion and other related notions such as inference, proof, argument, meaning of logical constants that may receive an assertion-based interpretation.

SUGGESTIONS FOR TOPICS (non-exhaustive list):

- Logical systems for assertion

- Constructivism and assertion

- Assertion and denial

- Justification of inference

- Problem of un-asserted contexts and expressivism

- Logical aspects of assertion and negation

- Illocutionary and pragmatic logics for assertions and other speech acts

- Diagrammatic systems and assertion (e.g., existential graphs, assertive graphs, etc.)

- Assertion and content (propositional contents, assertion candidates, etc.)

- Assertion, knowledge, and ignorance

- Assertion and contexts

- Assertion-based meaning of logical constants

- Assertion and (formal) argumentation

- Assertion and grounding

- History and philosophy of the logical notion of assertion

A Satellite event to WAP 2019 is the workshop "Peirce on Assertion"


Following the workshop we will produce:

-          A special issue of Journal of Applied Logics - IfCoLoG Journal of Logics and their Applications on the themes of the meeting. Speakers at the workshop will be invited to submit full papers based on their talks for peer review.

-          A special section of the journal Transactions of the Charles S. Peirce Society. Speakers of the talks accepted in the satellite workshop  "Peirce on Assertion" will be invited to submit full papers.


Please send an abstract of no more than 500 words to  by 5 July, 2019.

In the body of the email in which you submit the abstract, please include author name(s), the title of the talk and your affiliation. Include the abstract in a separate document (PDF) attached in the email with no identifying information in the document. Notification of acceptance/rejection will be given by 15 July, 2019.


Deadline for submissions: 5 July, 2019

Notifications of acceptance: 15 July, 2019

Workshop dates:  12- 14 September, 2019

Junior scholars whose paper (on Peircean themes on assertion) is accepted to the satellite workshop "Peirce on Assertion" may apply funding from the Charles S. Peirce Society to partially cover their participation costs.
