World Logic Day
The ability to think is one of the most defining features of humankind. In different cultures, the definition of humanity is associated with concepts such as consciousness, knowledge and reason. According to the classic western tradition, human beings are defined as "rational" or "logical animals". Logic, as the investigation on the principles of reasoning, has been studied by many civilizations throughout history and, since its earliest formulations, logic has played an important role in the development of philosophy and the sciences.
On 26 November 2019, the 40th General Conference of UNESCO proclaimed 14 January to be World Logic Day, a global day of supporting the development of logic through teaching and research, as well as to public dissemination of the discipline. The date chosen to celebrate World Logic Day, 14 January, corresponds to the date of death of Kurt Gödel and the date of birth of Alfred Tarski, two of the most prominent logicians of the twentieth century.
The Conseil International de Philosophie et des Sciences Humaines (CIPSH) and its member organisation, the Division for Logic, Methodology and Philosophy of Science and Technology of the International Union of History and Philosophy of Science and Technology (DLMPST/IUHPST), are coordinating the dynamic and global annual celebration of World Logic Day aiming at fostering international cooperation, promoting the development of logic, in both research and teaching, supporting the activities of associations, universities and other institutions involved with logic, and enhancing public understanding of logic and its implications for science, technology and innovation.
