Constitutional Law in Greece

By: Philippos C. Spyropoulos,Theodore P. Fortsakis

Derived from the renowned multi-volume International Encyclopaedia of Laws, this very useful analysis of constitutional law in Greece provides essential information on the country’s sources of constitutional law, its form of government, and its administrative structure. Lawyers who handle transnational matters will appreciate the clarifications of particular terminology and its application. Throughout the book, the treatment emphasizes the specific points at which constitutional law affects the interpretation of legal rules and procedure. Thorough coverage by a local expert fully describes the political system, the historical background, the role of treaties, legislation, jurisprudence, and administrative regulations. The discussion of the form and structure of government outlines its legal status, the jurisdiction and workings of the central state organs, the subdivisions of the state, its decentralized authorities, and concepts of citizenship. Special issues include the legal position of aliens, foreign relations, taxing and spending powers, emergency laws, the power of the military, and the constitutional relationship between church and state. Details are presented in such a way that readers who are unfamiliar with specific terms and concepts in varying contexts will fully grasp their meaning and significance. Its succinct yet scholarly nature, as well as the practical quality of the information it provides, make this book a valuable time-saving tool for both practising and academic jurists. Lawyers representing parties with interests in Greece will welcome this guide, and academics and researchers will appreciate its value in the study of comparative constitutional law.

A Therapy for Dying Democracies

By: Theodore C. Stathis

A Therapy for Dying Democracies By: Theodore C. Stathis The world economic crisis and the provocatively unjust distribution of wealth have exposed the real crisis, which is a political one. All the malfunctioning democracies that are gradually growing into oligarchic governments have become the main focus of many political experts. "Are Democracies Dying?" or "How Democracies Die" are a couple of titles belonging to corresponding books on democracy. Because of them, global interest in ancient Greek democracy has been significantly reinvigorated, and even though a lot of publications refer to it, they do not propose any functional and substantial solutions that keep up with the present; as a result, direct democracy is being rejected, not only by the enemies of this political system, but also by well-meaning prominent figures and public officials, who consider it as being nothing but a utopia. The book contains a remedy for our modern malfunctioning democracies, which suffer from a lack of democracy. Actually, the dying democracies, one by one, are removing their'' democratic masks'' and reveal their real identity, which is oligarchic in nature. A Therapy for Dying Democracies is a unique proposal and shows how the operational difficulties of ancient Greek democracy can be bypassed, and presents for the first time worldwide an effective way that shows how true democratic governments can be established today.

Microcosmic God

Volume II: The Complete Stories of Theodore Sturgeon

By: Theodore Sturgeon

The second of a planned 10 volumes that will reprint all Sturgeon's short fiction covers his prolific output during 1940 and 1941, after which he suffered five years of writer's block. Showcasing Sturgeon's early penchant for fantasy, the first six selections include whimsical ghost stories, such as "Cargo," in which a World War II munitions freighter is commandeered by invisible, peace-loving fairies. With the publication of his enduring SF classic, "Microcosmic God," Sturgeon finally found his voice, combining literate, sharp-edged prose with fascinating speculative science while recounting the power struggle between a brilliant scientist, who creates his own miniature race of gadget makers, and his greedy banker. Voice found or not, every one of the stories here is readable and entertaining today because of Sturgeon's singular gifts for clever turns of phrase and compelling narrative. As Samuel R. Delaney emphasizes in an insightful introduction, Sturgeon was the single most influential SF writer from the 1940s through the 1960s.

Theodore Roosevelt

An Autobiography

By: Theodore Roosevelt

Theodore Roosevelt's writing has the same verve, panache, and energy as the life he lived. Perhaps no president in U.S. history--not even Jefferson--had so many opinions and intellectual interests, believed in so many causes, or worked so hard to translate his beliefs into action. A hard-headed idealist, an unabashed interventionist, a crusader on behalf of environmental preservation and against big business "trusts," he was also a writer of uncommon grace and passion with a gift for the memorable phrase. His autobiography, one of the two or three finest ever written by a U.S. president, abounds in exciting episodes of personal transformation and insights into the bitter politics of the day. Roosevelt was a sickly youth who steeled himself for a life of vigor, growing up surrounded by wealth in nineteenth-century Manhattan but vacationing in the West, where he rode with cowboys and learned to revere and study the natural world. His book describes his early failures in his political career and his ascent from the New York City police board to assistant secretary of the Navy where he advocated war with Spain, to his brief stint and public renown as a Rough Rider; and on to the governorship of New York, vice presidency under McKinley, and finally the presidency itself. Elting Morison's new introduction analyzes what Roosevelt has included-and not included-about his many political conflicts, his role in the acquisition of the Panama Canal, and the deaths of his wife and his mother. As everywhere in his writing, the personality of T.R.-alert, voluble, forceful, compassionate-shines forth from this book, which remains a singular study of a dynamic and, in many respects, exemplary man who was also a key figure in the Age of Reform.
