Introduction

The proclamation of the World Logic Day (January 14) by UNESCO, in association with the International Council for Philosophy and Human Sciences, aims to draw attention to the intellectual history, conceptual meaning and practical implications of logic among inter-disciplinary scientific communities and the general public. To this end, the Society for Epistemology and Logic is organising The Heterodox in Logic and Reason, our first World Logic Day event, to be celebrated between 13-16 January 2021.

This event will feature lectures based primarily on the legacy of José Francisco Miró Quesada Cantuarias (1918-2019), who was the most important Peruvian philosopher of logic and mathematics. He was mainly concerned with constructing a theory of reason adequate for understanding the most important logical and mathematical discoveries of his time: Gödel’s incompleteness theorems and ‘heterodox logics’ (name coined by him). He also coined the name ‘paraconsistent logic’, which designates those logical systems for which the principles of non contradiction and explosion do not hold generally. He has also been a pioneer in the fields of deontic logic and logic of law with his article ‘La lógica del deber ser y su eliminabilidad’ (The logic of ought and its eliminability), written the same year as von Wright’s Deontic Logic (1951).

Publication

Origin of the World Logic Day

On January 14, 2019 was organised the first World Logic Day in about 60 locations all over the world. On the basis of a detailed report, a project was presented by Jean-Yves Béziau, Editor-in-Chief of Logica Universalis and President of the Brazilian Academy of Philosophy, in April 2019 in Paris, to the Ambassador of Brazil at UNESCOMaria Edileuza Fontenele Reis, in order for this day to be a UNESCO international days. After the approval by the Brazilian government, the Ambassador presented the project during the meeting of the UNESCO Executive Council, backed by 17 other countries, and it was approved on October 17, 2019. On the basis of the decision of the Executive Council, January 14, was officially proclaimed as the World Logic Day at the 40th session of the General Conference of UNESCO in Paris, November 12-27, 2019.
