O dia 14 de janeiro deste ano foi comemorado o primeiro dia mundial da lógica em mais de 60 localidades no mundo inteiro.
1st World Logic Day: 14 January 2019
A semana que vem vou estar em Paris em particular para discutir com representantes da UNESCO do reconhecimento / da oficialização do dia mundial da lógica.
Até agora recebi cerca de 130 cartas de pesquisadores de 37 paises apoiando esta oficalização (alguns extratos a seguir), inclusivo do mais famoso logico vivo, Saharon Shelah.
Um colega me falou que ele achava dificil conseguir juntar 100 cartas, o que era meu objetivo inicial, e falou que talvez seria mais facil coletar assinaturas para uma carta so. Nem tinha pensado nisso, teria parecido mais com uma reclamação, em vez que o que estamos buscando é uma proclamação. No final ficou interessante porque cada um tentou explicar porque ele/ela achava a lógica importante.
Do Brasil recebi cartas de: Adonai Sant'Anna, Alexandre Costa-Leite, Cezar Mortari (enquanto presidente da SBL), Décio Krause, Fabien Schang, Francisco Miraglia, Hercules Feitosa, Itala D'Ottaviano, Julio Stern, Marcelo Finger, Marcos Silva, Mario Benevides, Ricardo Silvestre, Rodrigro Freire, Walter Nascimento. Mais cartas são bemvindas, so me mandar por e-mail.
A segunda edição, dia 14 de Janeiro de 2020, ja esta sendo preparada.
Fui convivado para a cidade de Brno, onde Gödel nasceu, com keynote speaker desta cerimônia na ocasião da qual a municipalidade vai atribuir o nome de Kurt Gödel a uma rua da cidade.

Given the current trend towards political populism, manipulation, intimidation, and disregard for truth, there is a need to re-emphasise the rational argument, which was born very much at the same time as democracy itself. (Bob Coecke, Oxford, UK).
Despite its tremendous relevance, it is considered by many as “part of” something, part of philosophy, part of mathematics, part of computer science, part of linguistics, etc., rather than a discipline as a whole, and this concretely affects logicians of all sorts and the communication with others, henceforth the efficiency of its future impact on the human society. Even within the austere field of Mathematics, Logic is often wrongly understood, if understood at all: if some Logic is taught at an undergraduate level, it often stays down to the study of truth tables and a misleading interpretation of those. (Xavier Vidaux, Concepcion, Chile)
Aristotle regarded humans as rational animals, and it was Aristotle who developed the first formal system of logic. Logic has become increasingly important for our times, for both humans as individuals and humans as groups. These groups also more and more include the “intelligent machines” that we create. For this last witness the recent tragic crash of an airliner where the pilot apparently could not override the decisions of his auto-pilot.
Logic is an area of study that transcends the humanities, and sciences. It is not just its own discipline. It depends on other disciplines, and they depend on it --particularly linguistics, philosophy, mathematics and computer science.
(Mike Dunn, Indiana, USA)
Logic is a human invention that is used throughout the day, across society and across all cultures and allows us humans to achieve the very best for each other, our societies, our world and all the creatures and plants that share the world with us. Logic can bring us all together. It is also sometimes attacked, or neglected, in dark corners of societies, and it is worthwhile for supporters to have an opportunity to remind the world of its importance. (Mark Reynolds, Perth, Australia)
It is worth noting that for totalitarian states the heresy of heresies is logic. This idea was first said by George Orwell in his Nineteen Eighty- Four, the dystopian science-fiction:
“In the end the Party would announce that two and two made five, and you would have to believe it.”
Hence, the World Logic Day is to celebrate the most essential aspect of our knowledge and our social life to be open society. (Andrew Schumann, Kraków, Poland)
What is a correct argument? How can we check its correctness? Can the fundamental notions in mathematics or physics be based on admissible but mutually incompatible theories? Are our basic mathematical principles true? Since the times of Aristotle and the Stoics, Logic deals with these fundamental questions. Fundamental answers to these problems have been given by logicians, since the times of Aristotle and the Stoics. Today Logic is a key tool in AI, computer science, mathematics, linguistics and philosophy. Gottlob Frege, Kurt Gödel, Andrey Kolmogorov, John von Neumann, Giuseppe Peano, Abraham Robinson, Bertrand Russell, Alfred Tarski, Alan Turing, are just a few among many mathematicians, logicians and philosophers whose ideas on the above problems have had a profound influence in mathematics, science and social life. A World Logic Day will help to promote Logic and its benefits in society, and to give students and researchers opportunities to be made aware of the role of Logic in contemporary science, and to contribute to this fascinating human enterprise. (Daniele Mundici, Florence, Italy)
World Logic Day is especially important in our turbulent world as acknowledgement of the role of logic, argumentation and rationality for the whole of humanity, as unifying common ground and language for interactions between people and conflict resolution. (Ioannis Vandoulakis, Athens, Greece)
From our ancient history untill the present in the West, but also in the cultures and religions of the East, the Logos has been considered characteristically human, and a definition of the laws of the universe. The human faculty of language and reason is both constitutive of our individual thought, as well as our common ground and basis of mutual understanding. The formal study and practice of Logic has therefore been, and will always remain, a central and most honorable human endeavour. (Paul Dekker, Amsterdam, The Netherlands)
Un tel événement présente en effet des enjeux qui dépassent très largement les frontières de l’univers académique.
Il permettrait en particulier de célébrer le caractère universel de la raison humaine et la diversité de ses modes de déploiement à l’échelle de la planète. Il contribuerait ainsi aux initiatives scientifiques et culturelles pour la paix dont le monde actuel a tant besoin. (Claude Rosenthal, CNRS, Paris, France)
In modern societies logic is no more merely a foundational scientific discipline but a crucial part of the everyday algorithms that dominate more and more our life. Logic is the most universal formal language that allows to represent and solve real life problems in a more efficient way than informal reasoning can do. We live in the century of artificial intelligence and it is the development of logic that is at the heart of the endeavor to implement human rationality in machines. This development changes our culture all over the world and it should not be a process only scientist are engaged with and industry profits from but a process that all parts of society should be involved in. (Tim Lampert, Berlin, Germany)
World Logic Day is important as the acknowledgement of the role of logic for better understanding reasoning and modeling decision making process, and providing a common language. These activities are critical in fostering cooperation between individuals and more generally interest groups, in order to solve the major issues for humanity (economic, social, cultural, humanitarian…). (Dominique Luzeaux, Ministry of Defense, Paris, France)
Logic is both the discipline responsible for the invention of the computer and the one most relevant to the constraints of rational discourse. It is pursued in the most fully international way. The recognition of its importance by UNESCO would be a deeply encouraging moment of light in these dark times. (Timothy Williamson, Oxford, USA)
Since the central mission of UN is the maintenance of international peace and security, the international recognition of The World Logic Day by UN/UNESCO is a necessary (and already late) step towards a public consciousness about the strategic roles of logic in contemporary society. After all, logic is independent of personal beliefs and has no political boundaries. Logic is one of the indispensable common features that can be peacefully shared by all people. (Adonai Sant'Anna, Curitiba, Brazil)
