UNILOG'2015 - 5th World Congress and School on Universal Logic Istanbul, June 20-30, 2015 http://www.uni-log.org You can submit your abstract up to December 5 Since 2005 UNILOG has been a major event in logic, dealing with all aspects of logic and gathering top researchers from all over the world. The 1st edition was in Montreux, Switzerland (2005), the 2nd in Xi'an, China (2007), the 3rd in Lisbon, Portugal (2010), the 4th in Rio de Janeiro, Brazil (2013). The 5th edition will happen in Istanbul in 2015. In UNILOG'2015 there will be a school with about 30 tutorials followed by a congress with many workshops and invited speakers including Melvin Fitting, Bruno Poizat, Benedikt Löwe, Olivia Caramello, Luciano Floridi, Ernest Lepore, Ahti-Veikko Pietarinen. As in previous editions there will also be a contest (for this edition: The Future of Logic) and a secret speaker (a speaker whose identity is revealed only at the time of her/his/its talk). The tutorials of UNILOG'2015 will provide a serious background for a general knowledge of the logical universe They are divided into three categories: 1) History of Logic: the logic of Aristotle, Leibniz, Kant, Hegel, etc. 2) Logic and XXX: Logic and Music, Logic an Colours, Logic and Nonsense, Logic and Information, Logic and the Theory of Relativity, etc 3) Theorems: Compactness theorem, Completeness theorem, Lindström theorem, Gödel's incompleteness theorem, etc (these theorems will be presented in a universal perspective, i.e. examining what are the general vs particular features) During the congress there will be an amazing variety of workshops - The Idea of Logic: Historical Perspectives - Representation and reality: humans, animals and machines - Philosophy of non-classical logics - Computational Creativity, Concept Invention and General Intelligence - C3GI - Connexive Logics - Logic and the Web etc. The event is organized in combination with the 10th Panhellenic Logic Symposium https://samosweb.aegean.gr/pls10/ that will happen in Samos Island, Greece (the island where Pythagoras was born), June 11-15, 2015. A travel by bus from the nearby port of Kusadasi in Turkey up to Istanbul will be organized with stops on famous historical sites: Ephesus, Troy, etc. Special arrangements will exist for participants who wish to attend both conferences. UNILOG'2015 is sponsored by the Association of Symbolic Logic This means that students can apply for a grant to come: http://www.aslonline.org/studenttravelawards.html
