January 14th
World Logic Day
World Logic Day is an international day declared by UNESCO in collaboration with the International Council for Philosophy and Humanities (CIPSH) in November 2019, celebrated annually on 14 January. It intends to bring the intellectual history, conceptual significance, and practical implications of the logic of attention to the attention of interdisciplinary scholarly communities and the wider public.
The chosen date for celebrating World Logic Day, January 14th, corresponds to the death of Kurt Gödel and the birth of Alfred Tarski, two of the most important logicians of the 20th century. The Association Logica Universalis, an informal meta-association promoting logic closely linked to Jean-Yves Béziau, supported the celebration of World Logic Day 2019 by encouraging logicians from around the world to organize independent events on January 14th, 2019. Approximately sixty such events were organized in 33 countries. The success of this informal first World Logic Day was part of the discussions at the 40th General Conference of UNESCO in November 2019, which led to its formal declaration by UNESCO.
In the 21st century, the discipline of logic is particularly relevant for our societies, economies, and sustainability. For example, computer science and information and communication technologies have their roots in logical and algorithmic thinking. In the field of ecology, we need logic more than ever before.
