This second edition of Quay Books' bestselling title retains all of the successful features of the first, plus additional material including a chapter on European psychiatric research. Foreword by Kevin Gournay.

When someone commits suicide it effects the people who care about them very deeply and it can be difficult for family and friends to understand what motivated their loved one to take their own life. This new book sets out the facts about suicide in a straightforward way in order to help people who are trying to come to terms with their loss or are close to someone experiencing suicidal thoughts. Written by someone who has experienced the pain of someone close committing suicide, this sympathetic book aims to support those struggling to find understanding. Suicide: The Facts contains 101 points about the reasons why people might chose to take their own life, the signs to look out for and how to cope. Did you know that one in ten adolescents think about suicide? Are you aware that suicidal feelings are often treatable and that attempting suicide can be a cry for help? If you, or someone you know, has been affected by suicide this book is a good starting point in finding the support you need.

This volume addresses the question of what it is like to be depressed. Despite the vast amount of research that has been conducted into the causes and treatment of depression, the experience of depression remains poorly understood. Indeed, many depression memoirs state that the experience is impossible for others to understand. However, it is at least clear that changes in emotion, mood, and bodily feeling are central to all forms of depression, and these are the book's principal focus. In recent years, there has been a great deal of valuable philosophical and interdisciplinary research on the emotions, complemented by new developments in philosophy of psychiatry and scientifically-informed phenomenology. The book draws on all these areas, in order to offer a range of novel insights into the nature of depression experiences. To do so, it brings together a distinguished group of philosophers, psychiatrists, anthropologists, clinical psychologists and neuroscientists, all of whom have made important contributions to current research on emotion and/or psychiatric illness.

The topic of the reduction of mental processes to biophysical mechanisms touches at the core of the mind-body problem, a puzzle in the philosophy of mind since the days of Descartes. This book is about philosophical aspects of neuroscience, centred on perspective dualism. The topic unfolds in the discussion of mechanisms in world and mind. Neuronal mechanisms of differing complexity are described in a general way. It is shown how models of such mechanisms may be classified and assigned to levels of systems theory. Reduction strategies are applied to processes of life, mind, and consciousness. The aim is physicalistic, to explore if and how the mental may be understood in terms of biophysics and its mechanisms.

NIKOLA TESLA (1856 ~ 1943) was a Serbian American inventor, electrical engineer, mechanical engi-neer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system. Tesla gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla for a short time as a consultant. His work in the formative years of electric power development was involved in a corporate alternating current/direct current "War of Currents" as well as various patent battles.The investors showed little interest in Tesla's ideas for new types of motors and electrical transmission equipment and also seemed to think it was better to develop an electrical utility than invent new systems. They eventually forced Tesla out leaving him penniless. He even lost control of the patents he had generated since he had assigned them to the company in lieu of stock. He had to work at various electrical repair jobs and even as a ditch digger for $2 per day. Tesla considered the winter of 1886/1887 as a time of "terrible headaches and bitter tears." During this time, he questioned the value of his education. Chapter 1 My Early Life: The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain. Its ultimate purpose is the complete mastery of mind over the material world, the harnessing of the forces of nature to human needs. This is the difficult task of the inventor who is often misunderstood and unrewarded. But he finds ample compensation in the pleasing exercises of his powers and in the knowledge of being one of that exceptionally privileged class without whom the race would have long ago perished in the bitter struggle against pitiless elements.Speaking for myself, I have already had more than my full measure of this exquisite enjoyment, so much that for many years my life was little short of continuous rapture. I am credited with being one of the hardest workers and perhaps I am, if thought is the equivalent of labor, for I have devoted to it almost all of my waking hours. But if work is interpreted to be a definite performance in a specified time according to a rigid rule, then I may be the worst of idlers. Every effort under compulsion demands a sacrifice of life-energy. I never paid such a price. On the contrary, I have thrived on my thoughts.In attempting to give a connected and faithful account of my activities in this series of articles which will be presented with the assistance of the Editors of the Electrical Experimenter and are chiefly addressed to our young men readers, I must dwell, however reluctantly, on the impressions of my youth and the circumstances and events which have been instrumental in determining my career. Our first endeavors are purely instinctive, promptings of an imagination vivid and undisciplined. As we grow older reason asserts itself and we become more and more sys-tematic and designing. But those early impulses, although not immediately productive, are of the greatest moment and may shape our very destinies. Indeed, I feel now that had I understood and cultivated instead of suppressing them, I would have added substantial value to my bequest to the world. But not until I had attained manhood did I realize that I was an inventor..

The object of this work is to present to the student of medicine and the practitioner removed from the schools, a series of dissections demonstrative of the relative anatomy of the principal regions of the human body. Whatever title may most fittingly apply to a work with this intent, whether it had better be styled surgical or medical, regional, relative, descriptive, or topographical anatomy, will matter little, provided its more salient or prominent character be manifested in its own form and feature. The work, as I have designed it, will itself show that my intent has been to base the practical upon the anatomical, and to unite these wherever a mutual dependence was apparent.That department of anatomical research to which the name topographical strictly applies, as confining itself to the mere account of the form and relative location of the several organs comprising the animal body, is almost wholly isolated from the main questions of physiological and transcendental interest, and cannot, therefore, be supposed to speak in those comprehensive views which anatomy, taken in its widest signification as a science, necessarily includes. While the anatomist contents himself with describing the form and position of organs as they appear exposed, layer after layer, by his dissecting instruments, he does not pretend to soar any higher in the region of science than the humble level of other mechanical arts, which merely appreciate the fitting arrangement of things relative to one another, and combinative to the whole design of the form or machine of whatever species this may be, whether organic or inorganic. The descriptive anatomist of the human body aims at no higher walk in science than this, and hence his nomenclature is, as it is, a barbarous jargon of words, barren of all truthful signification, inconsonant with nature, and blindly irrespective of the cognitio certa ex principiis certis exorta. Still, however, this anatomy of form, although so much requiring purification of its nomenclature, in order to clothe it in the high reaching dignity of a science, does not disturb the medical or surgical practitioner, so far as their wants are concerned. Although it may, and actually does, trammel the votary who aspires to the higher generalizations and the development of a law of formation, yet, as this is not the object of the surgical anatomist, the nomenclature, such as it is, will answer conveniently enough the present purpose. The anatomy of the human form, contemplated in reference to that of all other species of animals to which it bears comparison, constitutes the study of the comparative anatomist, and, as such, establishes the science in its full intent. But the anatomy of the human figure, considered as a species, per se, is confessedly the humblest walk of the understanding in a subject which, as anatomy, is relationary, and branches far and wide through all the domain of an animal kingdom. While restricted to the study of the isolated human species, the cramped judgment wastes in such narrow confine; whereas, in the expansive gaze over all allying and allied species, the intellect bodies forth to its vision the full appointed form of natural majesty; and after having experienced the manifold analogies and differentials of the many, is thereby enabled, when it returns to the study of the one, to view this one of human type under manifold points of interest, to the appreciation of which the understanding never wakens otherwise. If it did not happen that the study of the human form (confined to itself) had some practical bearing, such study could not deserve the name of anatomical, while anatomical means comparative, and whilst comparison implies inductive reasoning. ?

One more point deserves notice. Butler often refers in “Life and Habit” to Darwin’s “Variations of Animals and Plants under Domestication.” When he does so it is always under the name “Plants and Animals.” More often still he refers to Darwin’s “Origin of Species by means Natural Selection,” terming it at one time “Origin of Species” and at another “Natural Selection,” sometimes, as on p. 278, using both names within a few lines of each other. Butler was as a rule scrupulously careful about quotations, and I can offer no explanation of this curious confusion of titles.? Since Samuel Butler published “Life and Habit” thirty-three [vii] years have elapsed—years fruitful in change and discovery, during which many of the mighty have been put down from their seat and many of the humble have been exalted. I do not know that Butler can truthfully be called humble, indeed, I think he had very few misgivings as to his ultimate triumph, but he has certainly been exalted with a rapidity that he himself can scarcely have foreseen. During his lifetime he was a literary pariah, the victim of an orga-nized conspiracy of silence. He is now, I think it may be said without exaggeration, universally accepted as one of the most remarkable English writers of the latter part of the nineteenth century. ??I will not weary my readers by quoting the numerous tributes paid by distinguished contemporary writers to Butler’s originality and force of mind, but I cannot refrain from illustrating the changed attitude of the sci-entific world to Butler and his theories by a reference to “Darwin and Modern Science,” the collection of essays published in 1909 by the University of Cambridge, in commemoration of the Darwin centenary. ??In that work Professor Bateson, while referring repeatedly to Butler’s biological works, speaks of him as “the most brilliant and by far the most interesting of Darwin’s opponents, whose works are at length emerging from oblivion.” ??R. A. STREATFEILD.?November, 1910.

The publication of Darwin’s The Origin of Species in 1859 marked a dramatic turning point in scientific thought. The volume had taken Darwin more than twenty years to publish, in part because he envisioned the storm of controversy it was certain to unleash. Indeed, selling out its first edition on its first day, The Origin of Species revolutionized science, philosophy, and theology. Darwin’s reasoned, documented arguments carefully advance his theory of natural selection and his assertion that species were not created all at once by a divine hand but started with a few simple forms that mutated and adapted over time. Whether commenting on his own poor health, discussing his experiments to test instinct in bees, or relating a conversation about a South American burrowing rodent, Darwin’s monumental achievement is surprisingly personal and delightfully readable. Its profound ideas remain controversial even today, making it the most influential book in the natural sciences ever written—an important work not just to its time but to the history of humankind.

In 1861, Henry Dircks, a civil engineer, of London, published a work entitled "Perpetuum Mobile; or, Search for Self-Motive Power, During the Seventeenth, Eighteenth and Nineteenth Centuries." The book contains 599 pages, and was followed in 1870, by a second series by the same author entitled "Perpetuum Mobile, or a History of the Search for Self-Motive Power from the Thirteenth, to the Nineteenth Century." In these two books there is amassed a wonderful amount of material showing on the part of the author diligence, great patience and wide and thorough search.The author of these works was not enamoured of his subject, and his books clearly show that he was not writing them because of any interest he had in the subject of Perpetual Motion. On the contrary, they appear to have been written because of a deep detestation entertained by the author for the subject of Perpetual Motion, and a contemptuous pity for any one seriously interested in the subject. Mr. Dircks's works may be said to be the works of a scold. His sentiments were deep, and his impulses strong, which accounts for the vast amount of labor he did in the preparation of his books. Those books are now out of print, and it is believed by the author of this book that they may well remain so. They contain much material that no one would be justified in wading through. The most complicated mechanisms devised by enthusiastic dreamers are shown in the same detail with which the inventors described them in presenting them to the public, or to the patent offices. Little is to be gained by this. So complicated are many of the devices that only technically trained engineers could read them understandingly, and few technically trained engineers are now greatly interested in self-motive power devices. We believe that every useful or interesting purpose is served if enough devices are collected, classified and presented to show the various principles relied upon by the inventors; with an explanation of why they failed—i. e., wherein the principles relied upon are wrong, and while possibly not out of harmony with any mechanical principles then known, are entirely out of harmony with principles since discovered and now well known. In the preparation of this volume a vast amount of the information furnished by the two works of Mr. Dircks has been rearranged, reclassified, and used.Everyone who has to any extent, by environment, associated with the mass of people who are not technically educated, knows that the persons who are still interested in the subject of Perpetual Motion, and who still seek its attainment, are not technically trained engineers or mathematicians, but for the greater part untrained people of naturally strong mechanical sense, and of natural mechanical and mathematical adaptation.This book is written for the perusal of that large class of people. It is not designed as an argument either for or against the possibility of the attainment of Perpetual Motion. The author is content to classify and present—clearly, it is hoped—the leading endeavors that have been known in that field of effort, and to explain their failure. It is believed by the author that the perusal of the present volume by anyone whose mind has been attracted by the subject of Perpetual Motion will result in an enlightenment, and, it is also believed, will have a tendency to direct his mind from a struggle with theories long ago exploded, and may result in directing his efforts to things practical, and not without hope of attainment.This work is offered only to minds mechanically or mathematically inclined. It is not even hoped that it will interest people who prefer fiction to fact, nor people who read simply for idle entertainment. ABOUT AUTHOR: The author has no apology to offer for the production of this book. He has spent his life in environments that have brought him into constant contact with mechanics, artisans and laborers as well as professional men, engineers, chemists and technical experts of various types. He knows a great many men—young men, for the most part—are constantly working on the old, old problem of Perpetual Motion; that much money, and much time are being spent in search of a solution for that problem which all scientific and technical men tell us is impossible of solution.It is believed by the author that a classification and presentation of selected groups of the devices produced in the past by which it was by the inventor believed, self-motive power had been attained, will save much work in fields already thoroughly exploited.So far as the author knows no book on the subject has appeared since 1870. The various encyclopedias published contain articles on the subject, but they are necessarily brief, and not satisfying to young men who have become interested in the subject.
