Can we prove the necessity of our best physical theories by rational means, without appeal to experience? This book recounts a few ingenious attempts to derive physical theories by reason only, beginning with Descartes' geometric construction of the world, and finishing with recent derivations of quantum mechanics from natural axioms. Deductions based on theological, metaphysical, or transcendental arguments are worth remembering for the ways they motivated and structured physical theory, even though we would now criticize their excessive confidence in the power of the mind. Other deductions more modestly relied on criteria for the comprehensibility of nature, including forms of measurability, causality, homogeneity, and correspondence. The central thesis of this book is that such criteria, when properly applied to idealized systems, effectively determine some of our most important theories as well as the mathematical character of the laws of physics. The relevant arguments are not purely rational, because only experience can tell us to which extent nature is comprehensible in a given way. Nor do they block the possibility of ever more varied forms of comprehensibility. They nonetheless suggest the inevitability of much of our theoretical physics.

A touchstone of the Enlightenment dispute between rationality and religious belief, David Hume's essay "Of Miracles" has elicited much commentary from proponents and critics ever since it was published over 250 years ago. Alexander George's lucid and sustained interpretation of Hume's essay provides fresh insights into this provocative, occasionally elusive, and always subtle text. The Everlasting Check will be read with interest by both students new to Hume and seasoned scholars. George does justice to the letter and spirit of Hume's essay, explaining the concepts and claims involved, making intelligible the essay's structure, and clarifying remarks that have long puzzled readers. Properly interpreted, the essay's central philosophical argument proves to be much hardier than Hume's detractors suggest. George considers a range of objections to Hume-some recent, some perennial-and shows why most fail, either because they are based on misinterpretations or because the larger body of Hume's philosophy answers them. Beyond an analysis and defense of Hume's essay, George also offers a critique of his own, appealing to Ludwig Wittgenstein's thoughts on magic and ritual to demonstrate that Hume misconstrues the character of religious belief and its relationship to evidence and confirmation. Raising a host of important questions about the connection between religious and empirically verified beliefs, George discusses why Hume's master argument can fail to engage with committed religious thought and why philosophical argumentation in general often proves ineffective in shaking people's deeply held beliefs.

Descartes' enormously influential Meditations seeks to prove a number of theses: that God is a necessary existent; that our minds are equipped to track truth and avoid error; that the external world exists and provides us with information to preserve our embodiment; and that minds are immaterial substances. The work is a treasure-trove of views and arguments, but there are controversies about the details of the arguments and about how we are supposed to unpack the views themselves. This Companion offers a rich collection of new perspectives on the Meditations, showing how the work is structured literally as a meditation and how it fits into Descartes' larger philosophical system. Topics include Descartes' views on philosophical method, knowledge, skepticism, God, the nature of mind, free will, and the differences between reflective and embodied life. The volume will be valuable to those studying Descartes and early modern philosophy more generally.

Charles Peirce, the founder of pragmatism, was a thinker of extraordinary depth and range - he wrote on philosophy, mathematics, psychology, physics, logic, phenomenology, semiotics, religion and ethics - but his writings are difficult and fragmentary. This book provides a clear and comprehensive explanation of Peirce's thought. His philosophy is presented as a systematic response to 'nominalism', the philosophy which he most despised and which he regarded as the underpinning of the dominant philosophical worldview of his time. The book explains Peirce's challenge to nominalism as a theory of meaning and shows its implications for his views of knowledge, truth, the nature of reality, and ethics. It will be essential reading both for Peirce scholars and for those new to his work.

'The ideal interpreter of the Ring ... a fascinating and valuable study ... absorbing and convincing' Sunday Times The Ring of the Nibelung is one of the greatest works of art created in modern times. Roger Scruton's brilliant and passionate exploration of the drama, music, symbolism and philosophy of Wagner's masterpiece - with its themes of love, death, sacrifice and freedom - shows how, ultimately, it expresses the truth about the human condition. 'Highly original and penetrating ... tremendous' Tim Blanning, Literary Review 'A rich, historical account ... After reading this book, only the most unadventurous reader would turn down the chance to see Wagner's masterpiece' Economist 'A brilliant gallop through the master's religious, musical and philosophical contexts' Sue Prideaux, Spectator 'Scruton is one of the finest philosopher-musicians since Schopenhauer' Jonathan Gaisman, Standpoint

This is the first comprehensive account of Kant's cosmopolitanism, highlighting its moral, political, legal, economic, cultural and psychological aspects. Contrasting Kant's views with those of his German contemporaries and relating them to current debates, Pauline Kleingeld sheds new light on texts that have been hitherto neglected or underestimated. In clear and carefully argued discussions, she shows that Kant's philosophical cosmopolitanism underwent a radical transformation in the mid 1790s and that the resulting theory is philosophically stronger than is usually thought. Using the work of figures such as Fichte, Cloots, Forster, Hegewisch, Wieland and Novalis, Kleingeld analyses Kant's arguments regarding the relationship between cosmopolitanism and patriotism, the importance of states, the ideal of an international federation, cultural pluralism, race, global economic justice and the psychological feasibility of the cosmopolitan ideal. In doing so, she reveals a broad spectrum of positions in cosmopolitan theory that are relevant to current discussions of cosmopolitanism.

'Two things', wrote Kant, 'fill the mind with ever new and increasing admiration and awe: the starry heavens above and the moral law within'. Many would argue that since Kant's day, the study of the starry heavens has advanced while ethics has stagnated, and in particular that Kant's ethics offers an empty formalism that tells us nothing about how we should live. In Acting on Principle Onora O'Neill shows that Kantian ethics has practical as well as philosophical importance. First published in 1975, the book is regarded as a classic account and defence of the Kantian ethical position. It addresses Kant's account of reasoning about action, in particular his controversial claim that the Categorical Imperative guides action and is basic to ethics and justice. This second edition offers a substantial new introduction and updated bibliography, and will be valuable for a wide readership in Kant studies and those studying ethics.

Kant's 'practical philosophy' comprehends a diverse group of his writings on ethics, politics, law, religion, and the philosophy of history and culture. Kristi E. Sweet demonstrates the unity and interdependence of these writings by showing how they take as their animating principle the human desire for what Kant calls the unconditioned - understood in the context of his practical thought as human freedom. She traces the relationship between this desire for freedom and the multiple forms of finitude that confront human beings in different aspects of practical life, and stresses the interdependence of the pursuit of individual moral goodness and the formation of community through the state, religion, culture and history. This study of Kant's approach to practical life discovers that doing our duty, itself the realization of our individual freedom, requires that we set for ourselves and pursue a whole constellation of social, political and other communal ends.

In this book, Jeanine Grenberg argues that everything important about Kant's moral philosophy emerges from careful reflection upon the common human moral experience of the conflict between happiness and morality. Through careful readings of both the Groundwork and the Critique of Practical Reason, Grenberg shows that Kant, typically thought to be an overly technical moral philosopher, in fact is a vigorous defender of the common person's first-personal encounter with moral demands. Grenberg uncovers a notion of phenomenological experience in Kant's account of the Fact of Reason, develops a new a reading of the Fact, and grants a moral epistemic role for feeling in grounding Kant's a priori morality. The book thus challenges readings which attribute only a motivational role to feeling; and Fichtean readings which violate Kant's commitments to the limits of reason. This study will be valuable to students and scholars engaged in Kant studies.

This is the first exposition of how Enlightenment thinkers viewed this idea that shapes the world today. The Scottish Enlightenment was the first intellectual movement to view commercial society as a distinct and distinctive social formation - one that still shapes our everyday lives. Christopher Berry explains why Enlightenment thinkers considered commercial society to be wealthier and freer than earlier forms, and charts the arguments Scottish philosophers put forward for and against the idea. This is the first book to focus on the Scottish Enlightenment's conception of commercial society, revealing it to be the movement's core idea. It analyses key works like Adam Smith's Wealth of Nations, David Hume's Essays and Treatises on Several Subjects and Adam Ferguson's Essay on the History of Civil Society. It looks at lesser-known works such as Robert Wallace's Dissertation on Numbers of Mankind.

When, in 1735, Alexander Gottlieb Baumgarten added a new discipline to the philosophical system, he not only founded modern aesthetics but also contributed to shaping the modern concept of art or 'fine art'. In The Founding of Aesthetics in the German Enlightenment, Stefanie Buchenau offers a rich analysis and reconstruction of the origins of this new discipline in its wider context of German Enlightenment philosophy. Present-day scholars commonly regard Baumgarten's views as an imperfect prefiguration of Kantian and post-Kantian aesthetics, but Buchenau argues that Baumgarten defended a consistent and original project which must be viewed in the context of the modern debate on the art of invention. Her book offers new perspectives on Kantian aesthetics and beauty in art and science.

Kant's Metaphysical Foundations of Natural Science is one of the most difficult but also most important of Kant's works. Published in 1786 between the first (1781) and second (1787) editions of the Critique of Pure Reason, the Metaphysical Foundations occupies a central place in the development of Kant's philosophy, but has so far attracted relatively little attention compared with other works of Kant's critical period. Michael Friedman's book develops a new and complete reading of this work and reconstructs Kant's main argument clearly and in great detail, explaining its relationship to both Newton's Principia and eighteenth-century scientific thinkers such as Euler and Lambert. By situating Kant's text relative to his pre-critical writings on metaphysics and natural philosophy and, in particular, to the changes Kant made in the second edition of the Critique, Friedman articulates a radically new perspective on the meaning and development of the critical philosophy as a whole.

Why should anybody take an interest in philosophy? Is it just another detailed study like metallurgy? Or is it similar to history, literature and even religion: a study meant to do some personal good and influence our lives? "Engaging and accessible, this vigorous swansong exemplifies many of Midgley's virtues, and revisits many of her favourite themes." - The Tablet In her last published work, Mary Midgley addresses provocative questions, interrogating the various forms of our current intellectual anxieties and confusions and how we might deal with them. In doing so, she provides a robust, yet not uncritical, defence of philosophy and the life of the mind. This defence is expertly placed in the context of contemporary debates about science, religion, and philosophy. It asks whether, in light of rampant scientific and technological developments, we still need philosophy to help us think about the big questions of meaning, knowledge, and value.

The early enlightenment has been seen as an epoch-making period in the development of modern Europe, marking the beginnings of the transition from a 'religious' to an essentially 'secular' understanding of human relations and generating in the process new accounts of the relationship between religion and politics, in which the idea of toleration figured centrally. In this volume of essays, leading scholars in the field challenge that view and explore the ways in which some of the most important discussions of toleration in the western tradition were shaped by understandings of natural theology and natural law. Far from representing a shift to non-religious ways of thinking about the world, the essays reveal the extent to which early enlightenment discussions of toleration presupposed a world-view in which God-given natural law established the boundaries between church and state and provided the primary point of reference for understanding claims to religious freedom. The book offers significant new interpretations of the relationship between natural theology and toleration in the works of Samuel Pufendorf, John Locke, G. W. Leibniz, Christian Thomasius, Jean Barbeyrac, and Francis Hutcheson. These interpretations suggest sometimes extensive revisions to contemporary thinking about these works and to the assumptions about the early enlightenment and its role in shaping liberal modernity it embodies. By carefully examining the arguments of these writers in their original contexts, without the interference of modern categories, and by setting those arguments in sequence, this book reveals an important transformation in modern thought, one that is yet continuous with the past and which poses some pointed questions for both the present and the future.

Descartes's Meditations, one of the most influential works in western philosophy, continues to provoke discussion and debate. This volume of original essays by leading established and emerging early modern scholars ranges over all six of the Meditations and explores issues such as scepticism, judgement, causation, the nature of meditation and the meditator s relation to God, the nature of personhood, Descartes theory of sense perception, and his ideas on the nature of substance. The contributors bring new insights to both central and less-studied topics in the Meditations, and connect the work with the rich historical and intellectual context in which Descartes forged his thought. The resulting volume will appeal to a wide range of scholars of early modern thought."

What is philosophy about? According to the author of this work (published in the first series of 'English Men of Letters' in 1879) it is fundamentally the answer to the question: 'What can I know?' T. H. Huxley (1825-95), the distinguished English scientist and disciple of Darwin, succeeds in giving a clear and succinct account of the way in which Scottish philosopher David Hume (1711-56) answered this question. The book is divided into two parts: in the first, Huxley provides the reader with a sketch of Hume's life, but the main emphasis of the book is in Part 2, where by expounding Hume's views on the object of philosophy, consciousness, theology, language and free will, Huxley guides the reader towards an understanding of how Hume's philosophical principles can be regarded as a search for the ultimate element out of which all valid knowledge may be shown to emerge.

Kant s "Critique of Pure Reason" is so outstanding among modern philosophical works, that it can be termed "the" foundation of modern philosophy. Schopenhauer termed it "the most important book ever to have been written in Europe." Otfried Hoffe guides the reader through the "Critique" one step at a time, expounding Kant s thoughts, submitting them to an interpretation and drawing a summary conclusion, placing the work and its topics within the context of its modern successors. A "critical" interpretation of Kant s text reveals that he had something to say on many discussions that are said to have originated after his death. Reducing his argumentation to its central tenets, it can be made stronger and applicable to current problems. Kant s eventual concern, however, even when writing theoretical philosophy, lay with the practical. Elaborating this concern and its connection to Kant s theoretical philosophy is a prime tenet of this book."

The story of the greatest of all philosophical friendships-and how it influenced modern thought David Hume is arguably the most important philosopher ever to have written in English, but during his lifetime he was attacked as "the Great Infidel" for his religious skepticism and deemed unfit to teach the young. In contrast, Adam Smith, now hailed as the founding father of capitalism, was a revered professor of moral philosophy. Remarkably, Hume and Smith were best friends, sharing what Dennis Rasmussen calls the greatest of all philosophical friendships. The Infidel and the Professor tells the fascinating story of the close relationship between these towering Enlightenment thinkers-and how it influenced their world-changing ideas. It shows that Hume contributed more to economics-and Smith contributed more to philosophy-than is generally recognized. The result is a compelling account of a great friendship that had great consequences for modern thought.

Kant's Critique of Judgment has often been interpreted by scholars as comprising separate treatments of three uneasily connected topics: beauty, biology, and empirical knowledge. Rachel Zuckert's book interprets the Critique as a unified argument concerning all three domains. She argues that on Kant's view, human beings demonstrate a distinctive cognitive ability in appreciating beauty and understanding organic life: an ability to anticipate a whole that we do not completely understand according to preconceived categories. This ability is necessary, moreover, for human beings to gain knowledge of nature in its empirical character as it is, not as we might assume it to be. Her wide-ranging and original study will be valuable for readers in all areas of Kant's philosophy.

The Groundwork of the Metaphysics of Morals is Kant's central contribution to moral philosophy, and has inspired controversy ever since it was first published in 1785. Kant champions the insights of 'common human understanding' against what he sees as the dangerous perversions of ethical theory. Morality is revealed to be a matter of human autonomy: Kant locates the source of the 'categorical imperative' within each and every human will. However, he also portrays everyday morality in a way that many readers find difficult to accept. The Groundwork is a short book, but its argument is dense, intricate and at times treacherous. This commentary explains Kant's arguments paragraph by paragraph, and also contains an introduction, a synopsis of the argument, six short interpretative essays on key topics of the Groundwork, and a glossary of key terms. It will be an indispensable tool for anyone wishing to study the Groundwork in detail.

A unifying theme of Loeb's work is epistemological - that Descartes and Hume advance theories of knowledge that rely on a substantial 'naturalistic' component, adopting one or another member of a cluster of psychological properties of beliefs as the goal of inquiry and the standard for assessing belief-forming mechanisms. Thus Loeb shows a surprising affinity between the epistemologies of the two figures -- surprising because they are often thought of as polar opposites in this respect.
Descartes and Hume are unique in that their philosophical texts are accessible beyond just a narrow audience in the history of philosophy; their ideas continue to be a vital part of the field at large. This volume will thus appeal to advanced students and scholars not just in the history of early modern philosophy but in epistemology and other core areas of the discipline.

Immanuel Kant's moral philosophy is one of the most distinctive achievements of the European Enlightenment. At its heart lies what Kant called the 'strange thing': the free, rational, human will. This introduction explores the basis of Kant's anti-naturalist, secular, humanist vision of the human good. Moving from a sketch of the Kantian will, with all its component parts and attributes, to Kant's canonical arguments for his categorical imperative, this introduction shows why Kant thought his moral law the best summary expression of both his own philosophical work on morality and his readers' deepest shared convictions about the good. Kant's central tenets, key arguments, and core values are presented in an accessible and engaging way, making this book ideal for anyone eager to explore the fundamentals of Kant's moral philosophy.

Kant infamously claimed that all human beings, without exception, are evil by nature. This collection of essays critically examines and elucidates what he must have meant by this indictment. It shows the role which evil plays in his overall philosophical project and analyses its relation to individual autonomy. Furthermore, it explores the relevance of Kant's views for understanding contemporary questions such as crimes against humanity and moral reconstruction. Leading scholars in the field engage a wide range of sources from which a distinctly Kantian theory of evil emerges, both subtle and robust, and capable of shedding light on the complex dynamics of human immorality.
