In the twenty-first century, humanity is reaching new heights of scientific understanding - and at the same time appears to be losing its mind. How can a species that discovered vaccines for Covid-19 in less than a year produce so much fake news, quack cures and conspiracy theorizing?

In Rationality, Pinker rejects the cynical cliché that humans are simply an irrational species - cavemen out of time fatally cursed with biases, fallacies and illusions. After all, we discovered the laws of nature, lengthened and enriched our lives and set the benchmarks for rationality itself. Instead, he explains, we think in ways that suit the low-tech contexts in which we spend most of our lives, but fail to take advantage of the powerful tools of reasoning we have built up over millennia: logic, critical thinking, probability, causal inference, and decision-making under uncertainty. These tools are not a standard part of our educational curricula, and have never been presented clearly and entertainingly in a single book - until now.

Rationality matters. It leads to better choices in our lives and in the public sphere, and is the ultimate driver of social justice and moral progress. Brimming with insight and humour, Rationality will enlighten, inspire and empower.

This complete collection of Francis Bacon's essays is superbly presented and meticulously faithful to the original publication. An intellectual possessed of a staggering breadth of knowledge and learning, Francis Bacon wrote many essays on a range of topics. Subjects such as married life, child rearing, the sins of envy and vainglory, and the virtues of friendship, love and good counsel are all thoughtfully expounded upon and detailed in these essays. Cautionary writings on the subjects of anger and revenge are also present; Bacon notably makes an impassioned plea for true justice, noting that the quality of mercy is a far higher virtue than the 'wild justice' born of angry revenge. Reflecting the early colonial times in which Francis Bacon lived, we also witness essays upon the subjects of travel, Empire, ambition and commerce. Well-traveled and curious about distant lands, it is also with experience that Bacon imbues color and depth to his essays.

The 'death' of German Idealism has been decried innumerable times since its revolutionary inception, whether it be by the 19th-century critique of Western metaphysics, phenomenology, contemporary French philosophy, or analytic philosophy. Yet in the face of two hundred years of sustained, extremely rigorous attempts to leave behind its legacy, German Idealism has resisted its philosophical death sentence. For this exact reason it is timely ask: What remains of German Idealism? In what ways does its fundamental concepts and texts still speak to us? Drawing together new and established voices from scholars in Kant, Fichte, Hegel, and Schelling, this volume offers a fresh look on this time-honoured tradition. It uses myriad of recently developed conceptual tools to present new and challenging theories of its now canonical figures.

"This collection of essays showcases recent work on Hume and the Is/Ought question. There are four distinct attempts to redefine and prove Hume's no-ought-from-is thesis in such a way as to evade the famous counterexamples of A.N. Prior. The rival approaches are explained and discussed together with their implications for meta-ethical theory" --Provided by publisher.

The fourteenth volume of the Second Edition covers central topics in philosophical logic that have been studied for thousands of years, since Aristotle: Inconsistency, Causality, Conditionals, and Quantifiers. These topics are central in many applications of logic in central disciplines and this book is indispensable to any advanced student or researcher using logic in these areas. The chapters are comprehensive and written by major figures in the field.

somewhat like Henkin's nonstandard interpretation of higher-order logics, while the right semantics [or logical modalities is an analogue to the standard of type theory in Henkin's sense. interpretation Another possibility would be to follow W.V. Quine's advice to give up logi- cal modalities as being beyond repair. Or we could also try to develop a logic of conceptual possibility, restricting the range of our "possible worlds" to those compatible with the transcendental presuppositions of our own conceptual sys- tem. This looks in fact like one of the most interesting possible theories I have dreamt of developing but undoubtedly never will. Its kinship with Kant's way of thinking should be obvious. Besides putting the entire enterprise of possible-worlds semantics into a perspective, we can also see that the actual history of possible-worlds seman- tics is more complicated than it might first appear to be. For the standard in- terpretation of modal logics has reared its beautiful head repeatedly in the writings of Stig Kanger, Richard Montague the pre-Montague-semantics theorist, and Nino Cocchiarella.

Most researchers would be amazed to discover that opinions they have about cherished themes in biology and medicine are biased. Van der Steen and Ho contend that logic and methodology are not well applied in biology and medicine, arguing that the impact of social and moral factors on claims within these two disciplines is underestimated. In response to this situation, Van der Steen and Ho present tools from logic and ethics for assessing existing literature. These tools will help to create sound articles and materials in the life sciences.

After reviewing logic and methodological approaches, broad guidelines are used to place science in a social context. Examples from life sciences illustrate the implementation of logic, methodology, and guidelines in forty-five brief case studies. Each study includes comments on quoted and paraphrased passages from a single article or book. Cross-references facilitate the assimilation of lessons from the text. Students, researchers, and scholars in biology, biomedicine, philosophy, and ethics as applied to the life sciences will find this guide useful in improving their research and writing skills.

Anti-realism is a doctrine about logic, language, and meaning with roots in the work of Wittgenstein and Frege. In this book, the author clarifies Dummett's case for anti-realism and develops his arguments further. He concludes by advocating a radical reform of our logical practices.

Things are particulars and their qualities are universals, but do universals have an existence distinct from the particular things describable by those terms? And what must be their nature if they do? This book provides a careful and assured survey of the central issues of debate surrounding universals, in particular those issues that have been a crucial part of the emergence of contemporary analytic ontology. The book begins with a taxonomy of extreme nominalist, moderate nominalist, and realist positions on properties, and outlines the way each handles the phenomena of predication, resemblance, and abstract reference. The debate about properties and philosophical naturalism is also examined. Different forms of extreme nominalism, moderate nominalism, and minimalist realism are critiqued. Later chapters defend a traditional realist view of universals and examine the objections to realism from various infinite regresses, the difficulties in stating identity conditions for properties, and problems with realist accounts of knowledge of abstract objects. In addition, the debate between Platonists and Aristotelians is examined alongside a discussion of the relationship between properties and an adequate theory of existence. The book's final chapter explores the problem of individuating particulars. The book makes accessible a difficult topic without blunting the sophistication of argument required by a more advanced readership.

Arguing Well is a lucid introduction to the nature of good reasoning, how to test and construct successful arguments. It assumes no prior knowledge of logic or philosophy. The book includes an introduction to basic symbolic logic. Arguing Well introduces and explains: * The nature and importance of arguments * What to look for in deciding whether arguments succeed or fail * How to construct good arguments * How to make it more certain that we reason when we should The book is ideal for any student embarking on academic study where presenting arguments are what matters most; in fact, for all people who want to understand the nature and importance of good reasoning and awaken their ability to argue well.

'A Geometry of Approximation' addresses Rough Set Theory, a field of interdisciplinary research first proposed by Zdzislaw Pawlak in 1982, and focuses mainly on its logic-algebraic interpretation. The theory is embedded in a broader perspective that includes logical and mathematical methodologies pertaining to the theory, as well as related epistemological issues. Any mathematical technique that is introduced in the book is preceded by logical and epistemological explanations. Intuitive justifications are also provided, insofar as possible, so that the general perspective is not lost.

Such an approach endows the present treatise with a unique character. Due to this uniqueness in the treatment of the subject, the book will be useful to researchers, graduate and pre-graduate students from various disciplines, such as computer science, mathematics and philosophy. It features an impressive number of examples supported by about 40 tables and 230 figures. The comprehensive index of concepts turns the book into a sort of encyclopaedia for researchers from a number of fields.

'A Geometry of Approximation' links many areas of academic pursuit without losing track of its focal point, Rough Sets.

"Exposes the vast gap between the actual science underlying AI and the dramatic claims being made for it." -John Horgan "If you want to know about AI, read this book...It shows how a supposedly futuristic reverence for Artificial Intelligence retards progress when it denigrates our most irreplaceable resource for any future progress: our own human intelligence." -Peter Thiel Ever since Alan Turing, AI enthusiasts have equated artificial intelligence with human intelligence. A computer scientist working at the forefront of natural language processing, Erik Larson takes us on a tour of the landscape of AI to reveal why this is a profound mistake. AI works on inductive reasoning, crunching data sets to predict outcomes. But humans don't correlate data sets. We make conjectures, informed by context and experience. And we haven't a clue how to program that kind of intuitive reasoning, which lies at the heart of common sense. Futurists insist AI will soon eclipse the capacities of the most gifted mind, but Larson shows how far we are from superintelligence-and what it would take to get there. "Larson worries that we're making two mistakes at once, defining human intelligence down while overestimating what AI is likely to achieve...Another concern is learned passivity: our tendency to assume that AI will solve problems and our failure, as a result, to cultivate human ingenuity." -David A. Shaywitz, Wall Street Journal "A convincing case that artificial general intelligence-machine-based intelligence that matches our own-is beyond the capacity of algorithmic machine learning because there is a mismatch between how humans and machines know what they know." -Sue Halpern, New York Review of Books

This monograph shows that, through a recourse to the concepts and methods of abstract algebraic logic, the algebraic theory of regular varieties and the concept of analyticity in formal logic can profitably interact. By extending the technique of Plonka sums from algebras to logical matrices, the authors investigate the different classes of models for logics of variable inclusion and they shed new light into their formal properties. The book opens with the historical origins of logics of variable inclusion and on their philosophical motivations. It includes the basics of the algebraic theory of regular varieties and the construction of Plonka sums over semilattice direct systems of algebra. The core of the book is devoted to an abstract definition of logics of left and right variable inclusion, respectively, and the authors study their semantics using the construction of Plonka sums of matrix models. The authors also cover Paraconsistent Weak Kleene logic and survey its abstract algebraic logical properties. This book is of interest to scholars of formal logic.

This volume discusses some crucial ideas of the founders of the analytic philosophy: Gottlob Frege, Bertrand Russell and Ludwig Wittgenstein, or the 'golden trio'. The book shows how these 'old' ideas are still present and influential in the current philosophical debates and to what extent these debates echo the original ideas. The collection aim is twofold: to better understand these fruitful ideas by placing them in the original setting, and to systematically examine these ideas in the context of the current debates animating philosophical discussions today. Divided into five sections, the book first sets the stage and offers a general introduction to the background influences, as well as delimitations of the initial foundational positions. This first section contains two papers dedicated to the discussion of realism and the status of science at that time, followed by two papers that tackle the epistemic status of logical laws. The next three sections constitute the core of the volume, each being dedicated to the most important figures in the early analytic tradition: Frege, Russell, and Wittgenstein. The last section gathers several essays that discuss either the relation between two or more analytic thinkers, or various important concepts such as 'predicativism' and 'arbitrary function', or the principles of abstraction and non-contradiction.

A selection of papers presented at the international conference Applied Logic: Logic at Work', held in Amsterdam in December 1992. Nowadays, the term applied logic' has a very wide meaning, as numerous applications of logical methods in computer science, formal linguistics and other fields testify. Such applications are by no means restricted to the use of known logical techniques: at its best, applied logic involves a back-and-forth dialogue between logical theory and the problem domain. The papers focus on the application of logic to the study of natural language, in syntax, semantics and pragmatics, and the effect of these studies on the development of logic. In the last decade, the dynamic nature of natural language has been the most interesting challenge for logicians. Dynamic semantics is here applied to new topics, the dynamic approach is extended to syntax, and several methodological issues in dynamic semantics are systematically investigated. Other methodological issues in the formal studies of natural language are discussed, such as the need for types, modal operators and other logical operators in the formal framework. Further articles address the scope of these methodological issues from other perspectives ranging from cognition to computation. The volume presents papers that are interesting for graduate students and researchers in the field of logic, philosophy of language, formal semantics and pragmatics, and computational linguistics.

This three volume collection gathers together responses to Weber's sociology in the period 1920-1945. Bryan Turner provides an extensive analysis of the reception of Weber.
