A perfectly matched layer (PML) absorbing material composed of a uniaxial anisotropic material is presented for the truncation of finite-difference time-domain (FDTD) lattices. It is shown that the uniaxial PML material formulation is mathematically equivalent to the perfectly matched layer method published by Berenger (see J. Computat. Phys., Oct. 1994). However, unlike Berenger's technique, the uniaxial PML absorbing medium presented in this paper is based on a Maxwellian formulation. Numerical examples demonstrate that the FDTD implementation of the uniaxial PML medium (...) is stable, equal in effectiveness as compared to Berenger's PML medium, while being more computationally efficient.

'To think often, and never to retain it so much as one moment, is a very useless sort of thinking' In An Essay concerning Human Understanding, John Locke sets out his theory of knowledge and how we acquire it. Eschewing doctrines of innate principles and ideas, Locke shows how all our ideas, even the most abstract and complex, are grounded in human experience and attained by sensation of external things or reflection upon our own mental activities. A thorough examination of (...) the communication of ideas through language and the conventions of taking words as signs of ideas paves the way for his penetrating critique of the limitations of ideas and the extent of our knowledge of ourselves, the world, God, and morals. Locke's masterpiece laid the foundation of British empiricism and is of enduring interest to anyone exploring the development of philosophical thought. This sensitive abridgement uses P. H. Nidditch's authoritative text, and together with an illuminating introduction and other features, makes Locke's arguments more accessible. (shrink)

Reissued in its revised 1866 second edition, this work by John Stuart Mill discusses the positivist views of the French philosopher and social scientist Auguste Comte. Comte is regarded as the founder of positivism, the doctrine that all knowledge must derive from sensory experience. The two-part text was originally printed as two articles in the Westminster Review in 1865. Part 1 offers an analysis of Comte's earlier works on positivism in the natural and social sciences, while Part 2 considers its (...) application in areas such as religion and ethics. Mill states that Comte is the first philosopher who has attempted to extend positivism 'to all objects of human knowledge'. Despite being critical of a number of Comte's views, such as the exclusion of psychology from positivist science, Mill acknowledges his fellow philosopher's influence in the face of common negative perceptions of the positivist movement.

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. (shrink)

Charles Sanders Peirce , the most important and influential of the classical American philosophers, is credited as the inventor of the philosophical school of pragmatism. The scope and significance of his work have had a lasting effect not only in several fields of philosophy but also in mathematics, the history and philosophy of science, and the theory of signs, as well as in literary and cultural studies. Largely obscure until after his death, Peirce's life has long been a subject of (...) interest and dispute. Unfortunately, previous biographies often confuse as much as they clarify crucial matters in Peirce's story. Ketner's new biographical project is remarkable not only for its entertaining aspects but also for its illuminating insights into Peirce's life, his thought, and the intellectual milieu in which he worked.

Charles Sanders Peirce was born in September 1839 and died five months before the guns of August 1914. He is perhaps the most important mind the United States has ever produced. He made significant contributions throughout his life as a mathematician, astronomer, chemist, geodesist, surveyor, cartographer, metrologist, engineer, and inventor. He was a psychologist, a philologist, a lexicographer, a historian of science, a lifelong student of medicine, and, above all, a philosopher, whose special fields were logic and semiotics. He is (...) widely credited with being the founder of pragmatism. In terms of his importance as a philosopher and a scientist, he has been compared to Plato and Aristotle. He himself intended "to make a philosophy like that of Aristotle." Peirce was also a tormented and in many ways tragic figure. He suffered throughout his life from various ailments, including a painful facial neuralgia, and had wide swings of mood which frequently left him depressed to the state of inertia, and other times found him explosively violent. Despite his consistent belief that ideas could find meaning only if they "worked" in the world, he himself found it almost impossible to make satisfactory economic and social arrangements for himself. This brilliant scientist, this great philosopher, this astounding polymath was never able, throughout his long life, to find an academic post that would allow him to pursue his major interest, the study of logic, and thus also fulfill his destiny as America's greatest philosopher. Much of his work remained unpublished in his own time, and is only now finding publication in a coherent, chronologically organized edition. Even more astounding is that,despite many monographic studies, there has been no biography until now, almost eighty years after his death. Brent has studied the Peirce papers in detail and enriches his account with numerous quotations from letters by Peirce and by his friends. This is a fascinating account of a p. (shrink)

The Scottish philosopher Thomas Reid first published Essays on Active Powers of Man in 1788 while he was Professor of Philosophy at King's College, Aberdeen. The work contains a set of essays on active power, the will, principles of action, the liberty of moral agents, and morals. Reid was a key figure in the Scottish Enlightenment and one of the founders of the 'common sense' school of philosophy. In Active Powers Reid gives his fullest exploration of sensus communis as the (...) basis of all philosophical inquiry. He uses common sense realism to argue for the existence of a stable external world, the existence of other minds, and to offer a powerful challenge to versions of the Theory of Ideas advocated by Hume and Locke . This is a key work of the Scottish Enlightenment that made important contributions to fundamental debates about the basis of philosophical inquiry. (shrink)

"The first two lectures place the alternative I defend -- a kind of pragmatic realism -- in a historical and metaphysical context. Part of that context is provided by Husserl's remark that the history of modern philosophy begins with Galileo -- that is, modern philosophy has been hypnotized by the idea that scientific facts are all the facts there are. Another part is provided by the analysis of a very simple example of what I call 'contextual relativity'. The position I (...) defend holds that truth depends on conceptual scheme and it is nonetheless 'real truth'. "In my third lecture I turn to the Kantian antecedents of this view, explaining what I think should be retained of the Kantian idea of autonomy as the central theme of morality, and extracting from Kant's work a 'moral image of the world' that connects the ideals of equality and intellectual liberty. In this lecture I defend the idea that moral images are an indispensible part of our moral and cultural heritage. "In the final lecture I defend the idea of moral objectivity. I compare our epistemological positions in ethics, history, analysis of human character, and science, and I argue that in no area can we hope for a 'foundation' which is more ultimate than the beliefs that actually, at a given time, function as foundational in the area, the beliefs concerning which one has to say 'this is where my spade is turned'. In ethics such beliefs are represented in moral images of the world.". (shrink)

Author Max Black argues that language should conform to the discovered regularities of experience it is radically mistaken to assume that the conception of language is a mirror of reality.

What is philosophy about? According to the author of this work it is fundamentally the answer to the question: 'What can I know?' T. H. Huxley , 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 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.

Process and Reality, Whitehead’s magnum opus, is one of the major philosophical works of the modern world, and an extensive body of secondary literature has developed around it. Yet surely no significant philosophical book has appeared in the last two centuries in nearly so deplorable a condition as has this one, with its many hundreds of errors and with over three hundred discrepancies between the American and the English editions, which appeared in different formats with divergent paginations. The work itself (...) is highly technical and far from easy to understand, and in many passages the errors in those editions were such as to compound the difficulties. The need for a corrected edition has been keenly felt for many decades. (shrink)

Familiarity with Charles Darwin's treatise on evolution is essential to every well-educated individual. One of the most important books ever published--and a continuing source of controversy, a century and a half later--this classic of science is reproduced in a facsimile of the critically acclaimed first edition.

In the Critique of Judgement, Kant offers a penetrating analysis of our experience of the beautiful and the sublime. He discusses the objectivity of taste, aesthetic disinterestedness, the relation of art and nature, the role of imagination, genius and originality, the limits of representation, and the connection between morality and the aesthetic. He also investigates the validity of our judgements concerning the degree in which nature has a purpose, with respect to the highest interests of reason and enlightenment. The work (...) profoundly influenced the artists, writers, and philosophers of the classical and romantic period, including Hegel, Schelling, Schopenhauer, and Nietzsche. In addition, it has remained a landmark work in fields such as phenomenology, hermeneutics, the Frankfurt School, analytical aesthetics, and contemporary critical theory. Today it remains an essential work of philosophy, and required reading for all with an interest in aesthetics. (shrink)

In The Origin of Species (1859) Darwin challenged many of the most deeply-held beliefs of the Western world. Arguing for a material, not divine, origin of species, he showed that new species are achieved by "natural selection." The Origin communicates the enthusiasm of original thinking in an open, descriptive style, and Darwin's emphasis on the value of diversity speaks more strongly now than ever. As well as a stimulating introduction and detailed notes, this edition offers a register of the many (...) writers referred to by Darwin in the text. (shrink)

C.S. Peirce, the American philosopher and a principal figure in the development of the modern study of semiotics, struggled, mostly during his later years, to work out a systematic method for classifying sciences. By doing this, he hoped to define more clearly the various tasks of these sciences by showing how their individual effects are interrelated and how these effects, considered in their interrelations, establish pragmatic meanings for each individual science. Much of his work was centered on the meaning and (...) function of logic in relation to other areas of human knowledge. By rightly defining the work of logic, Peirce argued, the work of the other sciences could be pursued with more rigorous reasoning. Beverley Kent closely examines the published and unpublished writings of Peirce and carefully attends to the chronological development of his systems of classification; she thereby shows for the first time in the scholarly literature how seeming contradictions in Peirce's evolving classification are really part of an increasingly clear position. Logic (or "normative semiotic"), Peirce came to understand, is actually dependent on ethics and aesthetics for its principles. Kent shows how Peirce's working out of the classification of logic in relation to other sciences is a clue to the significant differences between his early and late philosophy and, perhaps even more important, to a reading of his more general claims for a philosophy of "pragmaticism." This work will be of interest to readers of Peirce and American philosophy, to historians of logic and semiotics, and to those more generally interested in the history of systems of knowledge-classification.

This book presents a remarkable diversity of contemporary opinions on the prospects of addressing philosophical topics from a psychological perspective. It considers the history and philosophical merits of psychologism, and looks systematically at psychologism in phenomenology, cognitive science, epistemology, logic, philosophy of language, philosophical semantics, and artificial intelligence.

This monograph attempts to clarify one significant but much neglected aspect of Peirce's contribution to the philosophy of science. It was written in 1963 as my M. A. thesis at the Uni versity of Illinois. Since the topic is still neglected it is hoped that its pUblication will be of use to Peirce scholars. I should like to acknowledge my indebtedness to Dr. Max Fisch who broached this topic to me and who advised me con tinuously through its development, assisting (...) generously with his own insights and unpublished Peirce manuscripts.

In this systematic introduction to the philosophy of Charles S. Peirce, the author focuses on four of Peirce's fundamental conceptions: pragmatism and Peirce's development of it into what he called 'pragmaticism'; his theory of signs; his phenomenology; and his theory that continuity is of prime importance for philosophy. He argues that at the centre of Peirce's philosophical project is a unique form of metaphysical realism, whereby continuity and evolutionary change are both necessary for our understanding of experience. In his final (...) chapter Professor Hausman applies this version of realism to contemporary controversies between anti-realists and anti-idealists. Peirce's views are compared to those of such contemporary figures as Davidson, Putnam, and Rorty. The book will be of particular interest to philosophers concerned with American philosophy and current debates on realism as well as linguists working in semiotics. (shrink)

Thomas Hobbes took a new look at the ways in which society should function, and he ended up formulating the concept of political science. His crowning achievement, Leviathan, remains among the greatest works in the history of ideas. Written during a moment in English history when the political and social structures as well as methods of science were in flux and open to interpretation, Leviathan played an essential role in the development of the modern world. This edition of Hobbes' landmark (...) work is based on the original text. It incorporates the author's own corrections and retains the period spelling and punctuation, offering both flavorful authenticity and the utmost clarity of expression. (shrink)
