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.

The Gifford Lectures were established in 1885 at the universities of St Andrews, Glasgow, Aberdeen and Edinburgh to promote the discussion of 'Natural Theology in the widest sense of the term - in other words, the knowledge of God', and some of the world's most influential thinkers have delivered them. The 1901–2 lectures given in Edinburgh by American philosopher William James are considered by many to be the greatest in the series. The lectures were published in book form in 1902 (...) and have been reprinted many times. James, who was educated in the United States and Europe, and spent much of his career teaching philosophy at Harvard, was very influential in the development of modern psychology, and in these twenty lectures he explores the personal experience of religion. Some of the topics include religion and neurology, 'the sick soul', saintliness, and mysticism. (shrink)
For this 1897 publication, the American philosopher William James brought together ten essays, some of which were originally talks given to Ivy League societies. Accessible to a broader audience, these non-technical essays illustrate the author's pragmatic approach to belief and morality, arguing for faith and action in spite of uncertainty. James thought his audiences suffered 'paralysis of their native capacity for faith' while awaiting scientific grounds for belief. His response consisted in an attitude of 'radical empiricism', which deals practically rather (...) than ideologically with real-world phenomena. When facing a 'momentous' decision about belief, he says, we both can and must choose the best hypothesis. The first four essays apply this principle to religious faith, and the rest explore the pragmatic approach to such topics as determinism, ethics and individual achievement. James developed his ideas further in The Varieties of Religious Experience and Pragmatism, both of which are reissued in this series. (shrink)
Noted psychologist and philosopher develops his own brand of pragmatism, based on theories of C. S. Peirce. Emphasis on "radical empiricism," versus the transcendental and rationalist tradition. One of the most important books in American philosophy. Note.
One of the great American pragmatic philosophers alongside Peirce and Dewey, William James delivered these eight lectures in Boston and New York in the winter of 1906–7. Though he credits Peirce with coining the term 'pragmatism', James highlights in his subtitle that this 'new name' describes a philosophical temperament as old as Socrates. The pragmatic approach, he says, takes a middle way between rationalism's airy principles and empiricism's hard facts. James' pragmatism is both a method of interpreting ideas by their (...) practical consequences and an epistemology which identifies truths according to their useful outcomes. Furnished with many examples, the lectures illustrate pragmatism's response to classic problems such as the question of free will versus determinism. Published in 1907, this work further develops James's approach to religion and morality, introduced in The Will to Believe and The Varieties of Religious Experience , both reissued in this series.

One of the most influential men of his time, philosopher, psychologist, educator, and author William James (1842-1910) helped lead the transition from a predominantly European-centered nineteenth-century philosophy to a new "pragmatic" American philosophy. Helping to pave the way was his seminal book Pragmatism (1907), in which he included a chapter on "Truth," an essay which provoked severe criticism. In response, he wrote the present work, an attempt to bring together all he had ever written on the theory of knowledge, including (...) an article on the function of cognition, later polemic and expository contributions, and some replies to previous criticism. The result was a full and definitive expression of the pragmatist "epistemology" from James' point of view. In the book, he urges the reader to "turn away from abstractions, verbal solutions, fixed principles, and pretended absolutes and look for concreteness and facts, action and power," arguing that "the ultimate test for us of what a truth means is the conduct it dictates or inspires." For students, scholars--anyone interested in William James or the history of American philosophical thought--this book offers an in-depth exposition of the influential ideas of one of the greatest American thinkers.

Still-vital lectures on teaching deal with psychology and the teaching art, the stream of consciousness, the child as a behaving organism, education and behavior, native and acquired reactions, habit, association of ideas, attention, memory, acquisition of ideas, perception, will, and more. The three addresses to students are "The Gospel of Relaxation," "On a Certain Blindness in Human Beings," and "What Makes a Life Significant?" Preface. 2 black-and-white illustrations.
After completing his monumental work, The Principles of Psychology, William James turned his attention to serious consideration of such important religious and philosophical questions as the nature and existence of God, immortality of the soul, and free will and determinism. His interest in these questions found expression in various works, including The Varieties of Religious Experience, his classic study of spirituality. Based on the prestigious Gifford Lectures on Natural Religion he gave at the University of Edinburgh in 1901 and 1902, (...) the book--studded with richly concrete examples--documents and discusses various religious states of consciousness and covers such topics as the meaning of the term "divine," the reality of the unseen, the religion of healthy-mindedness, the sick soul, the divided self and the process of its unification, conversion, saintliness, and mysticism. One of the author's most popular works, The Varieties of Religious Experience remains one of the great books on the subject, especially noteworthy for the evidence it gives for religious experience as a unique phenomenon. This Dover edition will be the least expensive one in print. Unabridged republication of the second edition of The Varieties of Religious Experience: A Study in Human Nature, originally published by Longmans, Green and Co., New York, 1902. Index. (shrink)
The war against war is going to be no holiday excursion or camping party. The military feelings are too deeply grounded to abdicate their place among our ideals until better substitutes are offered than the glory and shame that come to nations as well as to individuals from the ups and downs of politics and the vicissitudes of trade. There is something highly paradoxical in the modern man's relation to war. Ask all our millions, north and south, whether they would (...) vote now (were such a thing possible) to have our war for the Union expunged from history, and the record of a peaceful transition to the present time substituted for that of its marches and battles, and probably hardly a handful of eccentrics would say yes. Those ancestors, those efforts, those memories and legends, are the most ideal part of what we now own together, a sacred spiritual possession worth more than all the blood poured out. Yet ask those same people whether they would be willing, in cold blood, to start another civil war now to gain another similar possession, and not one man or woman would vote for the proposition. In modern eyes, precious though wars may be they must not be waged solely for the sake of the ideal harvest. Only when forced upon one, is a war now thought permissible. -/- It was not thus in ancient times. The earlier men were hunting men, and to hunt a neighboring tribe, kill the males, loot the village and possess the females, was the most profitable, as well as the most exciting, way of living. Thus were the more martial tribes selected, and in chiefs and peoples a pure pugnacity and love of glory came to mingle with the more fundamental appetite for plunder. (shrink)
