Beginning with a review of formal languages and their syntax and semantics, Logic, Proof and Computation conducts a computer assisted course in formal reasoning and the relevance of logic to mathematical proof, information processing and philosophy. Topics covered include formal grammars, semantics of formal languages, sequent systems, truth-tables, propositional and first order logic, identity, proof heuristics, regimentation, set theory, databases, automated deduction, proof by induction, Turing machines, undecidability and a computer illustration of the reasoning underpinning Godel's incompleteness proof. LPC is designed as a multidisciplinary reader for students in computing, philosophy and mathematics.

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.

Informed by co-author Debby Hutchins' extensive teaching experience and research on logic education, The Art of Reasoning is the most effective text for teaching logic today. The Fifth Edition features a new chapter on cognitive biases, along with a new learning framework and newly designed problem sets that encourage incremental learning. Supporting resources are enhanced by InQuizitive, an award-winning adaptive learning tool that facilitates mastery of core concepts.

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.

As the foundation of our rationality, logic has traditionally been considered fixed, stable and constant. This conception of the discipline has been challenged recently by the plurality of logics and in this book, Pavel Arazim extends the debate to offer a new view of logic as dynamic and without a definite, specific shape. The Problem of Plurality of Logics examines the origins of our standard view of logic alongside Kant's theories, the holistic view, the issue of logic's pragmatic significance and Robert Brandom's logical expressivism. Arazim then draws on proof-theoretical approaches to present a convincing argument for a dynamic version of logical inferentialism, which opens space for a new freedom to modify our own logic. He explores the scope, possibilities and limits of this freedom in order to highlight the future paths logic could take, as a motivation for further research. Marking a departure from logical monism and also from the recent doctrine of logical pluralism in its various forms, this book addresses current debates concerning the expressive role of logic and contributes to a lively area of discussion in analytic philosophy.
