The Form of Truth - Hegel's Philosophical Logic (Hardcover): Elena Ficara The Form of Truth - Hegel's Philosophical Logic (Hardcover)
Elena Ficara
R3,856 Discovery Miles 38 560 Ships in 10 - 15 working days

This book is a consideration of Hegel's view on logic and basic logical concepts such as truth, form, validity, and contradiction, and aims to assess this view's relevance for contemporary philosophical logic. The literature on Hegel's logic is fairly rich. The attention to contemporary philosophical logic places the present research closer to those works interested in the link between Hegel's thought and analytical philosophy (Stekeler-Weithofer 1992 and 2019, Berto 2005, Rockmore 2005, Redding 2007, Nuzzo 2010 (ed.), Koch 2014, Brandom 2014, 1-15, Pippin 2016, Moyar 2017, Quante & Mooren 2018 among others). In this context, one particularity of this book consists in focusing on something that has been generally underrated in the literature: the idea that, for Hegel as well as for Aristotle and many other authors (including Frege), logic is the study of the forms of truth, i.e. the forms that our thought can (or ought to) assume in searching for truth. In this light, Hegel's thinking about logic is a fundamental reference point for anyone interested in a philosophical foundation of logic.

VIRUS DISEASES OF PLANTS VIRUS DISEASES OF PLANTS BY JOHN GRAINGER PH. D., B. Sc. OXFORD UNIVERSITY PRESS LONDON HUMPHREY MILFORD 1934 PREFACE THE need for a small book upon the subject of Plant Virus Diseases appeared during my teaching work at Leeds University and in the County of Yorkshire. The study of this subject is, indeed, developing rapidly, but it seemed that this was not sufficient justification for with holding a simple text-book from the student of Mycology or Plant Pathology. A comprehensive volume would be inappropriate, as yet, and would have a limited use. The aim of this book has therefore been to introduce the student to the phenorrfcria associated with Virus Diseases, rather than to provide him with descriptions of all known viroses it is typical rather than complete. Many pitfalls aw r ait the new worker on Virus Diseases, so it was decided to include descriptions of the various items of technique in common use. The list of references at the end of the volume will provide an introduction to the very extensive literature on the subject of Plant Viruses. In its compilation, accessibility and comprehensiveness o the papers quoted have been constantly in mind. The references cited in the text follow the general plan of the book, being representative, not exhaustive. It is with great pleasure that I acknowledge my in debtedness to many persons to my wife, for much con structive criticism and help, and to Dr. J. Henderson Smith, of Rothamsted, who criticized the manuscript in its early stages. Dr. J. Johnson, of Wisconsin University, U. S. A., has helped in ways too numerous to mention, and Prof. J. H. Priestley, of Leeds University, introduced me to the study of VirusDiseases of Plants, and helped consider ably in its prosecution. Many workers in Ireland, Holland, America, Germany, and our own country have given written and verbal communication of their results. The Oxford University Press has throughout been most cour teous and helpful. J-G - June, 1933. J CONTENTS . INTRODUCTORY. Historical i II.

Weight-Loss Apocalypse - Emotional Eating Rehab Through the HCG Protocol (Hardcover): Robin Phipps Woodall Weight-Loss Apocalypse - Emotional Eating Rehab Through the HCG Protocol (Hardcover)
Robin Phipps Woodall
R625 Discovery Miles 6 250 Ships in 10 - 15 working days

This book was written to start a new conversation about how Dr. Simeons' protocol has relevance, not only as a hormonal therapy, but as a means to end our national eating disorder. Instead of continuing to apply the protocol as a short-term diet, it shoulder be discussed as a real solution --a tool to end irrational eating for emotional fulfillment. This country is dealing with a crisis: an addiction to eating emotionally, and the obvious result is the overwhelming increase in obesity. Think about the number of people in our culture who eat without hunger. When you observe our nation's behavior with food, it's very clear that fat isn't what we should be obsessed about, and weight shouldn't be the target of the problem. We need a genuine desire to eat less, one that isn't dependent on weight loss as a reward. This requires each of us to be accountable for our own emotions, and find happiness in life not centrally stimulated by food. "Finally a book that credibly answers the questions every doctor, patient, and skeptic needs to know about the hCG protocol." - Dr. Heidi Anderson, Doctor of Osteopathic Medicine "I've been prescribing hCG for weight loss for over four years, and nothing I've read comes close to having this level of expertise. Without question, this is the most informative and enlightening book about Dr. Simeons' hCG protocol available." - Dr. Ed Hagen, OB/GYN "Robin's approach to the hCG protocol is ingenious. Using the protocol as a way to heal the mind and body as an emotional and physical therapy is exactly what this country needs." - Becky Crowther, Registered Dietitian, Life Coach

Science and Islam provides a detailed account of the relationship between Islam and science from the emergence of the Islamic scientific tradition in the eighth century to the present time. This relationship has gone through three distinct phases. The first phase began with the emergence of science in the Islamic civilization in the eighth century and ended with the rise of modern science in the West; the second period is characterized by the arrival of modern science in the Muslim world, most of which at that time was under colonial occupation; and the third period, which began around 1950, is characterized by a more mature approach to the major questions that modern science has posed for all religious traditions. Based on primary sources, the book presents a panorama of Islamic views on some of the major issues in the current science and religion discourse. Written in accessible language, Science and Islam is an authentic account of the multi-faceted and complex issues that arise at the interface of Islamic intellectual tradition and science. Rich in historical details, the book is a fascinating survey of the interaction of Islamic beliefs with the enterprise of science.

R1,318 Discovery Miles 13 180 Ships in 10 - 15 working days

The book introduces concepts on a wide range of materials and has several advantages over existing texts, including: 1. The presentation of a series of scientific postulates and laws of RF and microwaves, which lay the foundation for the behavior of waves and their propagation on transmission lines, is unique to this book compared with similar RF and Microwave texts.2. The presentation of classical laws and principles of electricity and magnetism, all inter-related, conceptually and graphically.3. There is a shift of emphasis from rigorous mathematical solutions of Maxwell's equations, and instead has been aptly placed on simple yet fundamental concepts that underlie these equations. This shift of emphasis will promote a deeper understanding of the electronics, particularly at RF/Microwave frequencies.4. Wave propagation in free space and tramsmission lines has been amply treated from a totally new standpoint. Designing RF/Microwave passive circuits using the Smith Chart as covered in this book becomes a systematic and yet pleasant task, which can easily be duplicated by any practitioner in the field.5. New technical terms are precisely defined as they are first introduced, thereby keeping the subject matter in focus and preventing misunderstanding, and 6. Finally the abundant use of graphical illustrations and diagrams brings a great deal of clarity and conceptual understanding, enabling difficult concepts to be understood with ease.The fundamentals of RF and microwave electronics can be mastered visually, through many tested practical examples in the book and in the accompanying CD using Microsoft Excel environment. This book is perfect for RF/microwave newcomers or industry veterans The material is presented lucidly and effectively through worked practical examples using both clear-cut math and vivid illustrations, which help the reader gain practical knowledge in passive circuit design using the Smith Chart.

R3,332 Discovery Miles 33 320 Ships in 18 - 22 working days

This book brings together contributions from leading figures in legal studies on analogy and related forms of reasoning in the law. Analogical reasoning-which relies on the concept of two different things being in some way like each other-is hugely important not just in the practice of law, but it is nonetheless strongly contested. This volume raises key questions like: What is the logical, argumentative, rhetorical, or just heuristic force of analogy in law? Is analogy really different from extensive interpretation, reasoning by precedent and appeal to paradigm?

Energy & Society (Revised) - The Relation Between Energy, Social Change, and Economic Development (Hardcover): Fred Cottrell Energy & Society (Revised) - The Relation Between Energy, Social Change, and Economic Development (Hardcover)
Fred Cottrell
R1,092 Discovery Miles 10 920 Ships in 18 - 22 working days

Energy and Society (Revised) When first published in 1955, this book was among the first interpretive treatments of the connection between a society's energy conditions and evolution of its culture. The book begins with a basic discussion of the earliest forms of energy uses and evolves through a discussion of how the evolution of alternative energy converters has impacted the growth of civilization. Dr.Cottrell takes us from food gathering societies up through the beginning of the industrial revolution into the age of nuclear power. With each step of change, he discusses how society has changed and the impact these changes have had on economic, moral and social issues. Today, more than any time in history, the questions of energy sources, energy conversion, energy uses and energy distribution are among the greatest challenges faced by civilization. In this book, Dr. Cottrell does not give you answers or predictions but takes you through the thought processes necessary to overcome the multible barriers we face in moving into the future.

Jeanine Mary Williamson
R1,652 Discovery Miles 16 520 Ships in 10 - 15 working days

Teaching to Individual Differences in Science and Engineering Librarianship: Adapting Library Instruction to Learning Styles and Personality Characteristics applies learning styles and personality characteristics to science and engineering library instruction. After introducing the idea that individuals tend to choose college majors and occupations in alignment with their learning style and personality characteristics, the book presents background on the Kolb Learning Styles model, the 16 PF (Personality Factor) framework, and the Big Five/Narrow Traits personality framework. It then reviews extant knowledge on the learning styles and personality characteristics of scientists, engineers and librarians. Next, the book considers general approaches to the personalization of instruction to learning styles and personality characteristics, opportunities for such personalization in science and engineering library instruction, and science and engineering librarian attitudes towards, and approaches to, this type of personalization of instruction.

R4,329 Discovery Miles 43 290 Ships in 10 - 15 working days

This volume is a collection of up-to-date articles on Maltese on all linguistic levels, demonstrating the variety of topics Maltese has to offer for linguists of all specializations. Two diachronic studies discuss the early contact of Maltese and Sicilian Arabic (Avram) and the possible lexical influence of Occitan-Catalan on Maltese in the 13th-15th century (Biosca & Castellanos). Fabri & Borg shed light on the rules that govern verb sequences in Maltese. Ceploe presents a corpus analysis of the syntactic and semantic properties of focus constructions in Maltese. Stolz & Ahrens analyze the behavior of prepositional phrases with identical heads under coordination. Wilmsen & Al-Sayyed study the use of mus as a negator in Maltese and beyond. Puech presents a detailed phonological analysis of Maltese and Tunisian Arabic based on prosody, syllabic structure, and stress. Azzopardi-Alexander gives a fine-grained analysis of phonological features in Maltese English, placing speakers on a Maltese-English continuum. Sciriha takes a visual approach to multilingualism in Malta with her quantitative study of public and private signs. Finally, Versteegh offers a thought-provoking perspective on the notion "mixed language" and its viability.
