Since the last century, scholars have acknowledged the original and relevant contribution of medieval Arabic philosophers and thinkers to the development of medieval Western logic and, more generally, to the history of logic. The Workshop on History of Arabic Logic has two main aims: to make better known the richness and importance of Arabic logic, that is, logic developed and studied in Arabic-speaking lands from the 8th to the 15th centuries CE; and to provide a forum for interaction and discussion by scholars of Arabic logic.

Invited Speakers: Saloua Chatti (Tunis), Khaled El-Rouayheb (Harvard), Wilfrid Hodges (British Academy) and Riccardo Strobino (Tufts).

Many disciplines, from mathematics to metaphysics, employ non-causal explanations. But what is the logic (or the logics) of non-causal explanation? What are the pros and cons of different logical approaches? Is the linguistic expression of non-causal explanation specifically codified in some natural language? Can algorithms pick up non-causal explanations in textual databases? The workshop welcomes formal and informal contributions both from within specific disciplines employing non-causal explanations and from a more general perspective.

Keynote speakers: Hannes Leitgeb (Munich), Francesca Poggiolesi (Paris) and Erik Weber (Ghent).

Over last decades, the empirical research on judicial decision-making has bloomed. However, the influence of these developments on traditional, conceptual theory of judicial decision-making has been mostly superficial. The impact of empirical findings on concepts such as judicial discretion, formalism, judicial rationality, legal interpretation, or rules vs. standards debate is yet to be determined. The aim of this interdisciplinary workshop is to combine perspectives of psychology, sociology, economics, criminology, neuroscience and other behavioral sciences, with the legal-theoretical approach to judicial decision-making.

Confirmed speakers: Jeffrey J. Rachlinski (Cornell), Frederick Schauer (Virginia).

This is the main annual summer school in the area of multiagent systems, intended for both PhD and MSc students.

The main goal of the European Agent Systems Summer School is to provide an exchange of knowledge among individuals and groups interested in various aspects of autonomous systems. This dissemination is provided by formal state-of-the-art courses conducted by leading experts in the field and by informal meetings during the event. A typical course is 4 hours long and provides a general introduction to the selected topic followed by in-depth exposition of recent and relevant contributions. Both the practical and theoretical aspects of Multi-Agent Systems are within the scope of EASSS.

In this symposium we look back at some of the results of the REINS project on responsible intelligent systems and look forward at new routes of investigation for responsible AI in general.

The starting point of the REINS project was to develop logic-based modelling techniques that enable responsibility checking of artificial agents. As the project progressed, that goal evolved into a more general objective to understand the concepts involved in the modelling of responsibility, and to find the formal models that characterize them. Formalization has been the main focus throughout the project, paving the way for a more precise and operationalizable understanding of the concepts involved in responsibility, machine ethics and deontic reasoning. We believe the symbolic methods that we use in our model driven approach are essential to the solution of the problem of coming to responsible AI, since responsibility is too abstract and precarious a notion to be learned through data-driven approaches. However, the interplay between model-driven and data-driven approaches is one of the new future directions we are interested in.

For this final symposium of the project, we invite philosophers, logicians and specialists from concrete application areas of responsible intelligent systems (the military, the police).

Recently, the focus of inquiries intop mathematical cognition is shifting towards the process of mathematical activity: what is it to have mathematical ability, and how do we acquire the knowledge how to do mathematics? These questions are informed by the various E-approaches to cognition (Extended, Embodied, Embedded, Enactive, Enculturated cognition): our bodies, our technology, our environment - both offline and online - our practices, our culture, our education, and our interactional history might all have some role to play in our mathematical ability and the development thereof. How mathematical cognition is shaped by these factors is a broad question that warrants an interdisciplinary approach.

The conference on Automated Deduction (CADE) is the major international forum at which research on all aspects of automated deduction is presented. The conference programme includes invited talks, paper presentations, workshops, tutorials, and system competitions. Furthermore, the Herbrand Award for Distinguished Contributions to Automated Deduction and the new Skolem Award(s) for influential historical CADE papers is presented at the conference.

ISIPTA 2019 is devoted to robustness and imprecision in uncertainty modelling, inference and decision making, focusing in particular on uncertainty frameworks that extend or replace the probabilistic one.

ISIPTA conferences are characterised by a friendly and cooperative style, a strong emphasis on in-depth discussion and a true openness to new ideas. We hope that you too will both enjoy and contribute to this unique atmosphere.

Formal Ethics is a common denominator for the application of tools from logic, decision theory, game theory, and social choice theory to the analysis of concepts in moral and political philosophy and to the development of ethical theory. It is a rapidly growing field of research which goes back to the work of Kenneth Arrow, Amartya Sen, John Harsanyi, Georg Henrik von Wright and others. The field has recently gained new impetus with formal work on non-classical logic, freedom and responsibility, value theory and the evolution of norms and conventions.

Keynote speakers: Edith Elkind (Oxford), Campbell Brown (LSE), and Ray Briggs (Stanford).

The Institute of Philosophy of the The Czech Academy of Sciences announces 'LOGICA 2019', the 33nd in the series of annual international symposia devoted to logic. The first session begins on the morning of Tuesday, 25 June. The symposium closes at noon Friday, 28 June.

Invited Speakers: David Makinson, Per Martin-Lof, Alessandra Palmigiano and David Ripley.

Next semester the University of Illinois at Chicago is hosting the annual graduate student conference in logic. It will be a weekend long conference with one plenary talk from a professor in Model Theory or Set Theory and then talks from grad students.

It is most likely that free housing and a few meals will be provided for all participants, while funding for travel expenses will be limited to national flights.

Traditional semantics gives the meaning of expressions in terms of conditions on one kind of primitive (e.g. truth, assertion, belief). Bilateral approaches hold that the meaning of expressions is characterized in terms of conditions on two, usually opposite primitives (e.g. truth and falsity, assertion and rejection, belief and disbelief). Recent years have witnessed the independent development of a variety of bilateral approaches to analyze phenomena such as negation, epistemic modality and counterfactuals, from both a proof-theoretic and a model-theoretic perspective. The workshop will bring together researchers from either perspective in order to provide a venue for the systematic exploration of commonalities, differences and potential interactions between such approaches.

Invited speakers: Maria Aloni (ILLC, Amsterdam), Teresa Marques (Logos, Barcelona), Greg Restall (Melbourne) and David Ripley (Monash).

The Symposium on Compositional Structures (SYCO) is an interdisciplinary series of meetings aiming to support the growing community of researchers interested in the phenomenon of compositionality, from both applied and abstract perspectives, and in particular where category theory serves as a unifying common language.  This new series aims to bring together the communities behind many previous successful events which have taken place over the last decade, including "Categories, Logic and Physics", "Categories, Logic and Physics (Scotland)", "Higher-Dimensional Rewriting and Applications", "String Diagrams in Computation, Logic and Physics", "Applied Category Theory", "Simons Workshop on Compositionality", and the "Peripatetic Seminar in Sheaves and Logic".

Invited speakers: Marie Kerjean (INRIA Bretagne Atlantique)  and Alessandra Palmigiano (Delft University of Technology and University of Johannesburg).

The 97th edition of the "Arbeitstagung Allgemeine Algebra" (Workshop on General Algebra, AAA) conference series is going to be held at Technische Universität Wien in Vienna, Austria. The conference topics include Universal Algebra, Connections with Model Theory, Lattices, Categories, Semigroups, Applications in Computer Science, Classical Algebra, and Interactions with Philosophy. The program will consist of five invited plenary lectures of one hour, as well as contributed talks of about 20-25 minutes held in up to three parallel sessions.

AUTOMATA 2019 is the official annual event of IFIP WG 1.5, the Working Group 5 (on Cellular Automata and Discrete Complex Systems), of the Technical Committee 1 (on Foundations of Computer Science), of the International Federation of Information Processing (IFIP).

The purpose of this conference is to highlight the major advances in the field and the development of new tools, to support the development of theory and applications of CA and DCS, and to identify and study within an inter- and multidisciplinary context the important fundamental aspects, concepts, notions and problems concerning CA and DCS.

ICALP is the main conference and annual meeting of the European Association for Theoretical Computer Science (EATCS). As usual, ICALP will be preceded by a series of workshops, which will take place on 8 July 2019.

ICALP 2019 will have three tracks:
Track A: Algorithms, Complexity and Games
Track B: Automata, Logic, Semantics, and Theory of Programming
Track C: Foundations of Networks and Multi-Agent Systems: Models, Algorithms and Information Management

The purpose of the International Conference on Agents and Artificial Intelligence is to bring together researchers, engineers and practitioners interested in the theory and applications in the areas of Agents and Artificial Intelligence. Two simultaneous related tracks will be held, covering both applications and current research work. One track focuses on Agents, Multi-Agent Systems and Software Platforms, Distributed Problem Solving and Distributed AI in general. The other track focuses mainly on Artificial Intelligence, Knowledge Representation, Planning, Learning, Scheduling, Perception Reactive AI Systems, and Evolutionary Computing and other topics related to Intelligent Systems and Computational Intelligence.

Computational and technological developments that incorporate natural language are proliferating. Adequate coverage encounters difficult problems related to partiality, underspecification, and context-dependency, which are signature features of information in nature and natural languages. Furthermore, agents (humans or computational systems) are information conveyors, interpreters, or participate as components of informational content. Generally, language processing depends on agents' knowledge, reasoning, perspectives, and interactions.

The ICAART Special Session covers theoretical work, applications, approaches, and techniques for computational models of information and its presentation by language (artificial, human, or natural in other ways). The goal is to promote intelligent natural language processing and related models of thought, mental states, reasoning, and other cognitive processes.

The workshop examines reasoning, argumentation and logic from the perspective of experimental pragmatics. Whereas these issues have a long tradition in the philosophy of language and theoretical linguistics, research in experimental pragmatics has come to focus on them only recently. This is surprising since pragmatic phenomena exert strong influence on which arguments count as sound and valid in everyday reasoning. Relevant phenomena include (a) the disambiguation of polysemous words, (b) context effects on the interpretation of content words and (c) pragmatic properties of logical connectives (e.g., order effects associated with and) as well as of quantifiers (e.g., the scalar implicature from some to not all). The workshop focuses on (i) experimental approaches and (ii) empirically driven models regarding these as well as other pragmatic phenomena in the domain of argumentation and reasoning.

Studying logic via semantics is a well-established and very active branch of mathematical logic with many applications in computer science and elsewhere. The area is characterized by results, tools and techniques stemming from various fields, including universal algebra, topology, category theory, order, and model theory. The programme of the conference TACL 2019 will focus on three interconnecting mathematical themes central to the semantic study of logic and their applications: topological, algebraic, and categorical methods.

On January 14, 1978, Kurt Gödel, one of the greatest logicians of all times passed away. Today, 50 years later, we have still not exhaustively explored, discussed and conclusively assessed all of Goedel's visionary ideas. With this informal, one-day workshop we provide a forum for interested scientists from various disciplines to meet and discuss unexplored aspects in Goedel's work. A particular focus will be on his philosophical views.

Computational modeling opens new prospects for philosophical exploration and argument. The role played by logic in 20th century philosophy, it can be argued, will be played by computational modeling in the 21st. This special issue is devoted first and foremost to examples of computer-aided or computer-instantiated modeling across the discipline, including but not limited to philosophy of science, cognitive science, philosophy of mind, theory of evolution, logic, philosophy of language, epistemology, and social and political philosophy. Computational techniques range from agent-based modeling to neural networks and data mining. Results can expand the role of intuition pumps and thought experiments, can be used to measure the robustness and parameter-sensitivity of basic models, can put techniques from other disciplines to work in philosophical analysis, can track unexpected consequences of basic assumptions, and can force philosophical assumptions to be made explicit. Beyond new answers, computational techniques can highlight new questions, including questions regarding model validation, complexity, computability, representation, and reality.
