Logic and philosophy have many interfaces, some dating back to Antiquity, some developed only recently. These two companion volumes chart the variety and liveliness of modern logic at this interface, opening windows to key topics for researchers in other disciplines and other cultural traditions, including India and China. The articles presented here were written by a wide spectrum of international experts, showing the field also as a living community of junior and senior scholars across different university departments. The articles in Volume 2 give extensive coverage of contacts with Philosophy, as well as several congenial other disciplines, from argumentation theory to cognitive science, game theory, and physics.

One of the questions that philosophers discuss is: How can we avoid, or at least reduce, errors when explaining the world? The skeptical answer to this question is: We cannot avoid errors since no statement is certain or even definitely plausible, but we can eliminate some past errors. This book advocates the skeptical position and discusses its practical applications in science, ethics, aesthetics, and politics. It brings philosophy down to earth and comprises an outline of a skeptical guide to the real world.

For thousands of years, mathematicians have used the timeless art of logic to see the world more clearly. In The Art of Logic, Royal Society Science Book Prize nominee Eugenia Cheng shows how anyone can think like a mathematician - and see, argue and think better.

Learn how to simplify complex decisions without over-simplifying them. Discover the power of analogies and the dangers of false equivalences. Find out how people construct misleading arguments, and how we can argue back.

Eugenia Cheng teaches us how to find clarity without losing nuance, taking a careful scalpel to the complexities of politics, privilege, sexism and dozens of other real-world situations. Her Art of Logic is a practical and inspiring guide to decoding the modern world.

This book tells the story of human civilisation as a series of historical periods, from Prehistory to the present day, describing the way each evolved into the next. In so doing, it explains the reasons behind what happened in each period, in terms of their contribution to the whole. It describes the way the ideas process evolves along with society, and explains the myths, religions and philosophical ideas which developed in the Ancient world, and the way its great empires appeared. Then, according to new technology and principles, how the events of the Middle Ages led to the rediscovery of the Americas and took us into the Modern periods, where the industrial revolution gave rise to the Middle Classes, and a new type of politics featured more representative forms of government. However, after two world wars which redefined the era, Postmodernity emerged as a term for the structure of Cold War society, which gave rise to the success of digital technology, but also led to the new problem of terrorism. Hence, many questions have arisen over the direction of human society, how it has evolved out of history, and how we address its issues. What type of problems can we solve at each stage? Perhaps with computers we are now able to analyse data in a way which was not possible before and this will lead to the next era.

The Lvov-Warsaw School was one of the most important currents in the 20th-century analytical movement. Kazimierz Twardowski, a student Franz Brentano and a professor of philosophy in Lvov, was the founder and at the same time an outstanding representative of the School. The papers included into the volume present comprehensively Twardowski's views and indicate what his lasting contribution to philosophy consists of.

Lawami' al-Nazar fi Tahqiq Ma'ani al-Mukhtasar is Ahmad b. Ya'qub al-Wallali's (d. 1128/1716) commentary on al-Sanusi's (d. 895/1490) compendium of logic, al-Mukhtasar. Al-Wallali was the first commentator on al-Sanusi's compendium after the author's autocommentary. In this publication, Ibrahim Safri offers a critical edition of this work, together with a study of the author's life and oeuvre. Safri also tries to show the indirect influence of Avicennism on logic in the Maghribi tradition in the seventeenth and eighteenth centuries. On the basis of his writings on logic and philosophical theology, al-Wallali was considered a master of rational sciences by his contemporaries.

Logics of Worlds stands as one of the most important texts in contemporary thought. Conceived as the sequel to Alan Badiou's Being and Event, the book expands upon and elucidates the questions that were posed in the first book. As a complex theory of worlds, the text has, for the most part, been misunderstood, but in William Watkin's diligent and critical close reading of the book, he makes the case for Logics of Worlds being the essential Badiou book for anyone interested in existence, meaning and the potential for radical change. For Watkin, this recasting of ontology is followed by a transformation of logic, which is not only a theory of being, but of appearing and allows Badiou to give new meaning to the object, body and relation. To do this, he explores these concepts through architecture, astronomy and renowned thinkers such as Kant, Hegel and Kierkegaard. For students of French Continental philosophy, ontology and Badiou himself, Watkin's commentary on the philosopher's text provides a brilliant and incisive new interpretation of this underrated work by the leading Continental philosopher of our time.

The philosopher Abu Nasr al-Farabi (c. 870-c. 950 CE) is a key Arabic intermediary figure. He knew Aristotle, and in particular Aristotle's logic, through Greek Neoplatonist interpretations translated into Arabic via Syriac and possibly Persian. For example, he revised a general description of Aristotle's logic by the 6th century Paul the Persian, and further influenced famous later philosophers and theologians writing in Arabic in the 11th to 12th centuries: Avicenna, Al-Ghazali, Avempace and Averroes. Averroes' reports on Farabi were subsequently transmitted to the West in Latin translation. This book is an abridgement of Aristotle's Prior Analytics, rather than a commentary on successive passages. In it Farabi discusses Aristotle's invention, the syllogism, and aims to codify the deductively valid arguments in all disciplines. He describes Aristotle's categorical syllogisms in detail; these are syllogisms with premises such as 'Every A is a B' and 'No A is a B'. He adds a discussion of how categorical syllogisms can codify arguments by induction from known examples or by analogy, and also some kinds of theological argument from perceived facts to conclusions lying beyond perception. He also describes post-Aristotelian hypothetical syllogisms, which draw conclusions from premises such as 'If P then Q' and 'Either P or Q'. His treatment of categorical syllogisms is one of the first to recognise logically productive pairs of premises by using 'conditions of productivity', a device that had appeared in the Greek Philoponus in 6th century Alexandria.

Casuistry and Early Modern Spanish Literature examines a neglected yet crucial field: the importance of casuistical thought and discourse in the development of literary genres in early modern Spain. Faced with the momentous changes wrought by discovery, empire, religious schism, expanding print culture, consolidation of legal codes and social transformation, writers sought innovation within existing forms (the novella, the byzantine romance, theatrical drama) and created novel genres (most notably, the picaresque). These essays show how casuistry, with its questioning of example and precept, and meticulous concern with conscience and the particularities of circumstance, is instrumental in cultivating the subjectivity, rhetorical virtuosity and spirit of inquiry that we have come to associate with the modern novel.
