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. 2. Despite its undeniable relevance to the development of knowledge, sciences and technologies, there is little public awareness on the importance of logic. The proclamation of World Logic Day by UNESCO, in association with the International Council for Philosophy and Human Sciences (CIPSH), intends to bring the intellectual history, conceptual significance and practical implications of logic to the attention of interdisciplinary science communities and the broader public. 3. A dynamic and global annual celebration of World Logic Day aims 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. Furthermore, the celebration of World Logic Day can also contribute to the promotion of a culture of peace, dialogue and mutual understanding, based on the advancement of education and science 4. On 14 January 2019, the first World Logic Day was celebrated as an initiative of universities, research institutes, foundations and associations active in the fields of mathematics, philosophy, computer sciences, engineering, economics and cognitive sciences. The existence of these networks, and their commitment to future annual celebrations of World Logic Day, offer credible assurance that the proclamation of the Day by UNESCO, in association with the relevant member organizations of the CIPSH, will lead to a solid action plan towards impact and added value. UNESCO’s commitment to World Logic Day will ensure that it has a broader and more geographically diverse orientation and connects organically to established programme priorities in the humanities.
