World Logic Day Banner Image

We aim to bring logicians in Korea together. We will celebrate World Logic Day proclaimed by UNESCO, and exchange opinions on current roles of logic in philosophy, science, and engineering.

On 14 January 2019, the first World Logic Day was celebrated as an initiative of universities, research institutes, foundations and associations active in mathematics, philosophy, computer science, engineering, economics, and cognitive science. For future annual celebrations of World Logic Day, it was officially claimed the Day by UNESCO, in association with the International Council for Philosophy and Human Sciences (CIPSH) on 13 November 2019. This year is for the third World Logic Day. For more events in other countries, please visit World Logic Day 2021.

Why is 14 January for World Logic Day? Nobody can disagree that Alfred Tarski and Kurt Gödel were most influential logicians in the 20th century. Alfred Tarski was born on 14 January 1901 and Kurt Gödel died on 14, January 1978. In memory of these two greatest logicians in the 20th century, 14 January is decided to be the day.
