3rd World Logic Day: January 14, 2021

January 14, 2021,  there will be the third edition of the World Logic Day.

After organizing the 1st edition with about 60 celebrations all over the world on January 14, 2019


I submitted the project to UNESCO to have this day in their calendar of international days 


This was successfully accomplished  through the Brazilian Ambassador at UNESCO, as explained here:



The third edition is managed by UNESCO through CIPSH (Conseil International de Philosophie et des Sciences Humaines)


Due to the pandemic, most of the celebrations will be on-line.

If you want to organize a celebration, be in touch with CIPSH. 

I will myself take part to several of these celebrations, in particular presenting the opening lecture "Understanding Rational Animals" at the celebration in Peru dedicated to Francisco Miró Quesada, former president of the FISP (Fédération internationale des sociétés de philosophie) and long time friend of Newton da Costa.

Evandro Agazzi, also former FISP president, will also be at this celebration in Lima:


Happy new year 2021
