Two weeks ago we had a celebration on the Square of Opposition for the 3rd edition of the World Logic Day.
On the page of the event you can find slides and papers:
We would like to remember that the 7th edition of the World Congress on the Square of Opposition should take place in Leuven, Belgium Sept 7-11, 2021:
and that the deadline to submit an abstract is April 21, 2021.
Due to coronavirus the event has been postponed from September 2020 to September 2021. All initially accepted abstracts are automatically approved for presentation in September 2021, and do not have to be resubmitted. If you did not submit an abstract for the cancelled 2020 edition, you can submit a contribution for the 2021 edition by sending a one page abstract before April 21, 2021 to: leuven2020@square-of-opposition.org.
