In 1983 Gerry Kennedy set off on a tour through Russia, China, Japan and the USA to visit others involved in the global anti-war movement. Only dimly aware of his Victorian ancestors: George Boole, forefather of the digital revolution and James Hinton, eccentric philosopher and advocate of polygamy, he had directly followed in the footsteps of two dynasties of radical thinkers and doers.Their notable achievements, in which the women were particularly prominent, involved many spheres. Boole's wife, Mary Everest, niece of George Everest, surveyor of the eponymous mountain, was an early advocate of hands-on education. Of the five talented Boole daughters, Ethel Voynich, wife of the discoverer of the enigmatic, still unexplained Voynich Manuscript, campaigned with Russian anarchists to overthrow the Tsar. Her 1897 novel The Gadfly, filmed later with music by Shostakovich, sold in millions behind the Iron Curtain. She was rumoured to have had an affair with the notorious 'Ace of Spies', Sidney Reilly. One of Ethel's sisters married Charles Howard Hinton: a leading exponent of the esoteric realm of the fourth dimension and inventor of the gunpowder baseball-pitcher.Of their descendants, Carmelita Hinton also pioneered progressive education in the USA at her school in Putney, Vermont. Her children dedicated their lives to Mao's China. Appalled by the dropping on Japan of the atomic bomb that she had helped design, Joan Hinton defected to China and actively engaged in the Cultural Revolution. William Hinton wrote the influential documentary Fanshen based on his experience in 1948 of revolutionary change in a Shanxi village. Other members of the clan became renowned in their fields of physics, entomology and botany. Their combined legacy of independent and constructive thinking is perhaps typified by the invention of the Jungle Gym: the climbing-frame now used by children the world over. In The Booles and the Hintons the author embarks on a quest to reveal the stories behind their remarkable lives.

Major shifts in the field of model theory in the twentieth century have seen the development of new tools, methods, and motivations for mathematicians and philosophers. In this book, John T. Baldwin places the revolution in its historical context from the ancient Greeks to the last century, argues for local rather than global foundations for mathematics, and provides philosophical viewpoints on the importance of modern model theory for both understanding and undertaking mathematical practice. The volume also addresses the impact of model theory on contemporary algebraic geometry, number theory, combinatorics, and differential equations. This comprehensive and detailed book will interest logicians and mathematicians as well as those working on the history and philosophy of mathematics.

The Calculus Collection is a useful resource for everyone who teaches calculus, in secondary school or in a college or university. It consists of 123 articles selected by a panel of veteran secondary school teachers. The articles focus on engaging students who are meeting the core ideas of calculus for the first time and who are interested in a deeper understanding of single-variable calculus. The Calculus Collection is filled with insights, alternative explanations of difficult ideas, and suggestions for how to take a standard problem and open it up to the rich mathematical explorations available when you encourage students to dig a little deeper. Some of the articles reflect an enthusiasm for bringing calculators and computers into the classroom, while others consciously address themes from the calculus reform movement. But most of the articles are simply interesting and timeless explorations of the mathematics encountered in a first course in calculus.

A mathematical sightseeing tour of the natural world from the author of THE MAGICAL MAZE Why do many flowers have five or eight petals, but very few six or seven? Why do snowflakes have sixfold symmetry? Why do tigers have stripes but leopards have spots? Mathematics is to nature as Sherlock Holmes is to evidence. Mathematics can look at a single snowflake and deduce the atomic geometry of its crystals; it can start with a violin string and uncover the existence of radio waves. And mathematics still has the power to open our eyes to new and unsuspected regularities - the secret structure of a cloud or the hidden rhythms of the weather. There are patterns in the world we are now seeing for the first time - patterns at the frontier of science, yet patterns so simple that anybody can see them once they know where to look.

Mathematics and logic have been central topics of concern since the dawn of philosophy. Since logic is the study of correct reasoning, it is a fundamental branch of epistemology and a priority in any philosophical system. Philosophers have focused on mathematics as a case study for general philosophical issues and for its role in overall knowledge- gathering. Today, philosophy of mathematics and logic remain central disciplines in contemporary philosophy, as evidenced by the regular appearance of articles on these topics in the best mainstream philosophical journals; in fact, the last decade has seen an explosion of scholarly work in these areas.
This volume covers these disciplines in a comprehensive and accessible manner, giving the reader an overview of the major problems, positions, and battle lines. The 26 contributed chapters are by established experts in the field, and their articles contain both exposition and criticism as well as substantial development of their own positions. The essays, which are substantially self-contained, serve both to introduce the reader to the subject and to engage in it at its frontiers. Certain major positions are represented by two chapters--one supportive and one critical.
The Oxford Handbook of Philosophy of Math and Logic is a ground-breaking reference like no other in its field. It is a central resource to those wishing to learn about the philosophy of mathematics and the philosophy of logic, or some aspect thereof, and to those who actively engage in the discipline, from advanced undergraduates to professional philosophers, mathematicians, and historians.

Despite its small stature, "if" occupies a central place both in everyday language and the philosophical lexicon. In allowing us to talk about hypothetical situations, "if" raises a host of thorny philosophical puzzles about language and logic. Addressing them requires tools from linguistics, logic, probability theory, and metaphysics. Justin Khoo uses these tools to navigate a maze of interconnected issues about conditionals, some of which include: the nature of linguistic communication, the relationship between logical and natural languages, and the relationship between different kinds of modality. According to Khoo's theory, conditionals form a unified class of expressions which share a common semantic core that encodes inferential dispositions. Thus, rather than represent the world, conditionals are devices used to communicate how we are disposed to infer. Khoo shows that this theory can be extended to predict the probabilities of conditionals, as well as how different kinds of conditionals differ both semantically and pragmatically. Khoo's book will make for a significant contribution to the literature on conditionals and should be of interest to philosophers, linguists, and computer scientists.

This book investigates the relationships between modern mathematics and science (in particular, quantum mechanics) and the mode of theorizing that Arkady Plotnitsky defines as "nonclassical" and identifies in the work of Bohr, Heisenberg, Lacan, and Derrida. Plotinsky argues that their scientific and philosophical works radically redefined the nature and scope of our knowledge. Building upon their ideas, the book finds a new, nonclassical character in the "dream of great interconnections" Bohr described, thereby engaging with recent debates about the "two cultures" (the humanities and the sciences).
Plotnitsky highlights those points at which the known gives way to the unknown (and unknowable). These points are significant, he argues, because they push the boundaries of thought and challenge the boundaries of disciplinarity. One of the book's most interesting observations is that key figures in science, in order to push toward a framing of the unknown, actually retreated into a conservative disciplinarity. Plotnitsky's informed, interdisciplinary approach is more productive than the disparaging attacks on postmodernism or scientism that have hitherto characterized this discourse.
Arkady Plotnitsky is Professor of English and Director, Theory and Cultural Studies Program, Purdue University. Trained in both mathematics and literary theory, he is author of several books, including "In the Shadow of Hegel: Complementarity, History and the Unconscious" and "Reconfigurations: Critical Theory and General Economy."

Der Begriff der Zahl ist ein vielfacher. Darauf weist uns schon die Mehrheit verschiedener Zahlworter hin, die in der Sprache des gewohnlichen Lebens auftreten und von den Grammatikern unter 5 folgenden Titeln aufgefiihrt zu werden pflegen: die Anzahlen oder Grundzahlen (numeralia cardinalia), die Ordnungszahlen (n. ordinalia), die Gattungszahlen (n. specialia), die Wiederho- lungszahlen (n. iterativa), die Vervielfaltigungszahlen (n. multi- plicativa) und die Bruchzahlen (n. partitiva). DaB die Anzahlen 10 als die ersten in dieser Reihe genannt werden, beruht ebenso wie die charakteristischen N amen, die sie sonst tragen - Grund- oder Kardinalzahlen -, nicht auf bloBer Konvention. Sie nehmen sprachlich eine bevorzugte SteHung dadurch ein, daB die samt- lichen iibrigen Zahlworter nur durch geringe Modifikationen aus 15 den Anzahlwortern hervorgehen (z. B. zwei, zweiter, zweierlei, zweifach, zweimal, zweitel). Die letzteren sind also wahrhafte Grundzahlworter.

Die einfachste Uberlegung scheint dies zu bestatigen. So handelt es sich bei den Gattungszahlen (einerlei, zweierlei usw. ) um eine Anzahl von Verschiedenheiten innerhalb einer Gattung; bei den Wieder- 25 holungszahlen (einmal, zweimal usw. ) um die Anzahl einer Wiederholung. Bei den Vervielfaltigungs- und Bruchzahlen dient die Anzahl dazu, das Verhaltnis eines in gleiche Teile geteilten Ganzen zu einem Teile bzw.

Our words and ideas refer to objects and properties in the external world; this phenomenon is central to thought, language, communication, and science. But great works of fiction are full of names that don't seem to refer to anything! In this book Kenneth A. Taylor explores the myriad of problems that surround the phenomenon of reference. How can words in language and perturbations in our brains come to stand for external objects? Reference is essential to truth, but which is more basic: reference or truth? How can fictional characters play such an important role in imagination and literature, and how does this use of language connect with more mundane uses? Taylor develops a framework for understanding reference, and the theories that other thinkers-past and present-have developed about it. But Taylor doesn't simply tell us what others thought; the book is full of new ideas and analyses, making for a vital final contribution from a seminal philosopher.

As discrete fields of inquiry, rhetoric and mathematics have long been considered antithetical to each other. That is, if mathematics explains or describes the phenomena it studies with certainty, persuasion is not needed. This volume calls into question the view that mathematics is free of rhetoric. Through nine studies of the intersections between these two disciplines, Arguing with Numbers shows that mathematics is in fact deeply rhetorical. Using rhetoric as a lens to analyze mathematically based arguments in public policy, political and economic theory, and even literature, the essays in this volume reveal how mathematics influences the values and beliefs with which we assess the world and make decisions and how our worldviews influence the kinds of mathematical instruments we construct and accept. In addition, contributors examine how concepts of rhetoric—such as analogy and visuality—have been employed in mathematical and scientific reasoning, including in the theorems of mathematical physicists and the geometrical diagramming of natural scientists. Challenging academic orthodoxy, these scholars reject a math-equals-truth reduction in favor of a more constructivist theory of mathematics as dynamic, evolving, and powerfully persuasive. By bringing these disparate lines of inquiry into conversation with one another, Arguing with Numbers provides inspiration to students, established scholars, and anyone inside or outside rhetorical studies who might be interested in exploring the intersections between the two disciplines. In addition to the editors, the contributors to this volume are Catherine Chaput, Crystal Broch Colombini, Nathan Crick, Michael Dreher, Jeanne Fahnestock, Andrew C. Jones, Joseph Little, and Edward Schiappa.

The use of diagrams in logic and geometry has encountered resistance in recent years. For a proof to be valid in geometry, it must not rely on the graphical properties of a diagram. In logic, the teaching of proofs depends on sentenial representations, ideas formed as natural language sentences such as "If A is true and B is true...." No serious formal proof system is based on diagrams.
This book explores the reasons why structured graphics have been largely ignored in contemporary formal theories of axiomatic systems. In particular, it elucidates the systematic forces in the intellectual history of mathematics which have driven the adoption of sentential representational styles over diagrammatic ones. In this book, the effects of historical forces on the evolution of diagrammatically-based systems of inference in logic and geometry are traced from antiquity to the early twentieth-century work of David Hilbert. From this exploration emerges an understanding that the present negative attitudes towards the use of diagrams in logic and geometry owe more to implicit appeals to their history and philosophical background than to any technical incompatibility with modern theories of logical systems.

In Mathematics of the Transcendental, Alain Badiou painstakingly works through the pertinent aspects of category theory, demonstrating their internal logic and veracity, their derivation and distinction from set theory, and the 'thinking of being'. In doing so he sets out the basic onto-logical requirements of his greater and transcendental logics as articulated in his magnum opus, Logics of Worlds. Now available in paperback, Mathematics of the Transcendental provides Badiou's readers with a much-needed complete elaboration of his understanding and use of category theory. The book is vital to understanding the mathematical and logical basis of his theory of appearing, as elaborated in Logics of Worlds and other works, and is essential reading for his many followers.

How is that when scientists need some piece of mathematics through which to frame their theory, it is there to hand? What has been called 'the unreasonable effectiveness of mathematics' sets a challenge for philosophers. Some have responded to that challenge by arguing that mathematics is essentially anthropocentric in character, whereas others have pointed to the range of structures that mathematics offers. Otavio Bueno and Steven French offer a middle way, which focuses on the moves that have to be made in both the mathematics and the relevant physics in order to bring the two into appropriate relation. This relation can be captured via the inferential conception of the applicability of mathematics, which is formulated in terms of immersion, inference, and interpretation. In particular, the roles of idealisations and of surplus structure in science and mathematics respectively are brought to the fore and captured via an approach to models and theories that emphasize the partiality of the available information: the partial structures approach. The discussion as a whole is grounded in a number of case studies drawn from the history of quantum physics, and extended to contest recent claims that the explanatory role of certain mathematical structures in scientific practice supports a realist attitude towards them. The overall conclusion is that the effectiveness of mathematics does not seem unreasonable at all once close attention is paid to how it is actually applied in practice.

This is the first English collection of the work of Albert Lautman, a major figure in philosophy of mathematics and a key influence on Badiou and Deleuze. Albert Lautman (1908-1944) was a French philosopher of mathematics whose work played a crucial role in the history of contemporary French philosophy. His ideas have had an enormous influence on key contemporary thinkers including Gilles Deleuze and Alain Badiou, for whom he is a major touchstone in the development of their own engagements with mathematics. "Mathematics, Ideas and the Physical Real" presents the first English translation of Lautman's published works between 1933 and his death in 1944. Rather than being preoccupied with the relation of mathematics to logic or with the problems of foundation, which have dominated philosophical reflection on mathematics, Lautman undertakes to develop an understanding of the broader structure of mathematics and its evolution. The two powerful ideas that are constants throughout his work, and which have dominated subsequent developments in mathematics, are the concept of mathematical structure and the idea of the essential unity underlying the apparent multiplicity of mathematical disciplines. This collection of his major writings offers readers a much-needed insight into his influence on the development of mathematics and philosophy.

For more than two generations, W. V. Quine has contributed fundamentally to the substance, the pedagogy, and the philosophy of mathematical logic. "Selected Logic Papers," long out of print and now reissued with eight additional essays, includes much of the author's important work on mathematical logic and the philosophy of mathematics from the past sixty years.

"The book is indeed a classic. Virtually every philosopher of science now writing about probabilistic inference has been influenced by Edwards' book, and his ideas are now as alive and relevant as they were when the book first appeared. Edwards is an absolutely seminal thinker in the foundations of statistics and scientific inference." -- Elliott Sober, University of Wisconsin-Madison.

"Full of appropriate examples (especially from genetics) and historical commentary, this monograph offers a rare simultaneous treatment of both mathematical and philosophical foundations." -- American Mathematical Monthly.

This new and expanded edition of A. W. F. Edwards' classic volume on scientific inference presents his most important published articles on the subject. Edwards argues that the appropriate axiomatic basis for inductive inference is not that of probability, with its addition axiom, but that of likelihood, the concept introduced by Fisher as a measure of relative support among different hypotheses. Starting from the simplest considerations and assuming no more than a basic acquaintancewith probability theory, the author sets out to reconstruct a consistent theory of statistical inference in science. Using the likelihood approach, he explores estimation, tests of significance, randomization, experimental design, and other statistical topics. Likelihood is important reading for students and professionals in biology, mathematical sciences, and philosophy.

"This book is commended to all philosophers of science who are interested in the problems of scientific inference." -- Search.

"This book, by a well-known geneticist, will do much to publicize the generality of the likelihoodmethod as a foundation for statistical procedure. It is both smoothly written and persuasive." -- Operations Research.

"Likelihood is an important text and, in addition, is a joy to read, being a paragon of lucid and witty exposition." -- Mathematical Gazette

Paolo Mancosu provides an original investigation of historical and systematic aspects of the notions of abstraction and infinity and their interaction. A familiar way of introducing concepts in mathematics rests on so-called definitions by abstraction. An example of this is Hume's Principle, which introduces the concept of number by stating that two concepts have the same number if and only if the objects falling under each one of them can be put in one-one correspondence. This principle is at the core of neo-logicism. In the first two chapters of the book, Mancosu provides a historical analysis of the mathematical uses and foundational discussion of definitions by abstraction up to Frege, Peano, and Russell. Chapter one shows that abstraction principles were quite widespread in the mathematical practice that preceded Frege's discussion of them and the second chapter provides the first contextual analysis of Frege's discussion of abstraction principles in section 64 of the Grundlagen. In the second part of the book, Mancosu discusses a novel approach to measuring the size of infinite sets known as the theory of numerosities and shows how this new development leads to deep mathematical, historical, and philosophical problems. The final chapter of the book explore how this theory of numerosities can be exploited to provide surprisingly novel perspectives on neo-logicism.

In this brief treatise, Ekelund explains some philosophical implications of recent mathematics. He examines randomness, the geometry involved in making predictions, and why general trends are easy to project, but particulars are practically impossible.

This book analyses the straw man fallacy and its deployment in philosophical reasoning. While commonly invoked in both academic dialogue and public discourse, it has not until now received the attention it deserves as a rhetorical device. Scott Aikin and John Casey propose that straw manning essentially consists in expressing distorted representations of one’s critical interlocutor. To this end, the straw man comprises three dialectical forms, and not only the one that is usually suggested: the straw man, the weak man and the hollow man. Moreover, they demonstrate that straw manning is unique among fallacies as it has no particular logical form in itself, because it is an instance of inappropriate meta-argument, or argument about arguments. They discuss the importance of the onlooking audience to the successful deployment of the straw man, reasoning that the existence of an audience complicates the dialectical boundaries of argument. Providing a lively, provocative and thorough analysis of the straw man fallacy, this book will appeal to postgraduates and researchers alike, working in a range of fields including fallacies, rhetoric, argumentation theory and informal logic.

Some combinations of attitudes-of beliefs, credences, intentions, preferences, hopes, fears, and so on-do not fit together right: they are incoherent. A natural idea is that there are requirements of "structural rationality" that forbid us from being in these incoherent states. Yet a number of surprisingly difficult challenges arise for this idea. These challenges have recently led many philosophers to attempt to minimize or eliminate structural rationality, arguing that it is just a "shadow" of "substantive rationality"-that is, correctly responding to one's reasons. In Fitting Things Together, Alex Worsnip pushes back against this trend-defending the view that structural rationality is a genuine kind of rationality, distinct from and irreducible to substantive rationality, and tackling the most important challenges for this view. In so doing, he gives an original positive theory of the nature of coherence and structural rationality that explains how the diverse range of instances of incoherence can be unified under a general account, and how facts about coherence are normatively significant. He also shows how a failure to focus on coherence requirements as a distinctive phenomenon and distinguish them adequately from requirements of substantive rationality has led to confusion and mistakes in several substantive debates in epistemology and ethics. Taken as a whole, Fitting Things Together provides the first sustained defense of the view that structural rationality is a genuine, autonomous, unified, and normatively significant phenomenon.

This collection examines the uses of quantification in climate science, higher education, and health. Numbers are both controlling and fragile. They drive public policy, figuring into everything from college rankings to vaccine efficacy rates. At the same time, they are frequent objects of obfuscation, manipulation, or outright denial. This timely collection by a diverse group of humanists and social scientists challenges undue reverence or skepticism toward quantification and offers new ideas about how to harmonize quantitative with qualitative forms of knowledge. Limits of the Numerical focuses on quantification in several contexts: climate change; university teaching and research; and health, medicine, and well-being more broadly. This volume shows the many ways that qualitative and quantitative approaches can productively interact-how the limits of the numerical can be overcome through equitable partnerships with historical, institutional, and philosophical analysis. The authors show that we can use numbers to hold the powerful to account, but only when those numbers are themselves democratically accountable.

This book introduces the reader to Serres' unique manner of 'doing philosophy' that can be traced throughout his entire oeuvre: namely as a novel manner of bearing witness. It explores how Serres takes note of a range of epistemologically unsettling situations, which he understands as arising from the short-circuit of a proprietary notion of capital with a praxis of science that commits itself to a form of reasoning which privileges the most direct path (simple method) in order to expend minimal efforts while pursuing maximal efficiency. In Serres' universal economy, value is considered as a function of rarity, not as a stock of resources. This book demonstrates how Michel Serres has developed an architectonics that is coefficient with nature. Mathematic and Information in the Philosophy of Michel Serres acquaints the reader with Serres' monist manner of addressing the universality and the power of knowledge - that is at once also the anonymous and empty faculty of incandescent, inventive thought. The chapters of the book demarcate, problematize and contextualize some of the epistemologically unsettling situations Serres addresses, whilst also examining the particular manner in which he responds to and converses with these situations.
