On First Principles

Origen’s On First Principles is a foundational work in the development of Christian thought and doctrine: it is the first attempt in history at a systematic Christian theology. For over a decade it has been out of print with only expensive used copies available; now it is available at an affordable price and in a more accessible format. On First Principles is the most important surviving text written by third-century Church father, Origen. Origen wrote in a time when fundamental doctrines had not yet been fully articulated by the Church, and contributed to the very formation of Christianity. Readers see Origen grappling with the mysteries of salvation and brainstorming how they can be understood. This edition presents G. W. Butterworth’s trusted translation in a new, more readable format, retains the introduction by Henri de Lubac, and includes a new foreword by John C. Cavadini. As St. Gregory of Nazianzus, Doctor of the Church, wrote: “Origen is the stone on which all of us were sharpened.”

New York Times Bestseller Editors' Choice —New York Times Book Review "Ricks knocks it out of the park with this jewel of a book. On every page I learned something new. Read it every night if you want to restore your faith in our country." —James Mattis, General, U.S. Marines (ret.) & 26th Secretary of Defense The Pulitzer Prize-winning journalist and #1 New York Times bestselling author offers a revelatory new book about the founding fathers, examining their educations and, in particular, their devotion to the ancient Greek and Roman classics—and how that influence would shape their ideals and the new American nation. On the morning after the 2016 presidential election, Thomas Ricks awoke with a few questions on his mind: What kind of nation did we now have? Is it what was designed or intended by the nation’s founders? Trying to get as close to the source as he could, Ricks decided to go back and read the philosophy and literature that shaped the founders’ thinking, and the letters they wrote to each other debating these crucial works—among them the Iliad, Plutarch’s Lives, and the works of Xenophon, Epicurus, Aristotle, Cato, and Cicero. For though much attention has been paid the influence of English political philosophers, like John Locke, closer to their own era, the founders were far more immersed in the literature of the ancient world. The first four American presidents came to their classical knowledge differently. Washington absorbed it mainly from the elite culture of his day; Adams from the laws and rhetoric of Rome; Jefferson immersed himself in classical philosophy, especially Epicureanism; and Madison, both a groundbreaking researcher and a deft politician, spent years studying the ancient world like a political scientist. Each of their experiences, and distinctive learning, played an essential role in the formation of the United States. In examining how and what they studied, looking at them in the unusual light of the classical world, Ricks is able to draw arresting and fresh portraits of men we thought we knew. First Principles follows these four members of the Revolutionary generation from their youths to their adult lives, as they grappled with questions of independence, and forming and keeping a new nation. In doing so, Ricks interprets not only the effect of the ancient world on each man, and how that shaped our constitution and government, but offers startling new insights into these legendary leaders.

NEW YORK TIMES BESTSELLER! History called on Harry Truman to unite the Western world against Soviet communism, but first he had to rally Republicans and Democrats behind America’s most dramatic foreign policy shift since George Washington delivered his farewell address. How did one of the least prepared presidents to walk into the Oval Office become one of its most successful? The year was 1947. The Soviet Union had moved from being America’s uneasy ally in the Second World War to its most feared enemy. With Joseph Stalin’s ambitions pushing westward, Turkey was pressured from the east while communist revolutionaries overran Greece. The British Empire was battered from its war with Hitler and suddenly teetering on the brink of financial ruin. Only America could afford to defend freedom in the West, and the effort was spearheaded by a president who hadn’t even been elected to that office. But Truman would wage a domestic political battle that carried with it the highest of stakes, inspiring friends and foes alike to join in his crusade to defend democracy across the globe. In Saving Freedom, Joe Scarborough recounts the historic forces that moved Truman toward his country’s long twilight struggle against Soviet communism, and how this untested president acted decisively to build a lasting coalition that would influence America’s foreign policy for generations to come. On March 12, 1947, Truman delivered an address before a joint session of Congress announcing a policy of containment that would soon become known as the Truman Doctrine. That doctrine pledged that the United States would “support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures.” The untested president’s policy was a radical shift from 150 years of isolationism, but it would prove to be the pivotal moment that guaranteed Western Europe’s freedom, the American Century’s rise, and the eventual collapse of the Soviet Union. Truman’s triumph over the personal and political struggles that confronted him following his ascension to the presidency is an inspiring tale of American leadership, fierce determination, bipartisan unity, and courage in the face of the rising Soviet threat. Saving Freedom explores one of the most pivotal moments of the twentieth century, a turning point when patriotic Americans of both political parties worked together to defeat tyranny.

This book emphasises the systemic character of Aristotle's philosophy by examining questions on metaphysics, epistemology, philosophy and mind and ethics. His reliance on dialectic as the method of philosophy appears to conflict with the metaphysical realist view of his conclusions.

This enlightening textbook for undergraduates on civil engineering degree courses explains structural design from its mechanical principles, showing the speed and simplicity of effective design from first principles. This text presents good approximate solutions to complex design problems, such as "Wembley-Arch" type structures, the design of thin-walled structures, and long-span box girder bridges. Other more code-based textbooks concentrate on relatively simple member design, and avoid some of the most interesting design problems because code compliant solutions are complex. Yet these problems can be addressed by relatively manageable techniques. The methods outlined here enable quick, early stage, "ball-park" design solutions to be considered, and are also useful for checking finite element analysis solutions to complex problems. The conventions used in the book are in accordance with the Eurocodes, especially where they provide convenient solutions that can be easily understood by students. Many of the topics, such as composite beam design, are straight applications of Eurocodes, but with the underlying theory fully explained. The techniques are illustrated through a series of worked examples which develop in complexity, with the more advanced questions forming extended exam type questions. A comprehensive range of fully worked tutorial questions are provided at the end of each section for students to practice in preparation for closed book exams.

In this second edition of First Principles: Building Perimeter Institute, Howard Burton tells the remarkable and unconventional story—with a bold and biting humour and surprising candour—of the founding of Perimeter Institute for Theoretical Physics in Waterloo, Canada. Howard was the Founding Director of Perimeter Institute and his experiences at developing the research and outreach mandates of PI are described in this thought-provoking book featuring a foreword by Nobel Laureate Roger Penrose. How was PI created from scratch, from first principles? What were the hurdles? What were the challenges? What was the ''Howard and Mike show'' all about and what did BlackBerrys and RIM have to do with PI? In vivid and compelling detail, Howard describes his remarkable odyssey of partnering with BlackBerry founder Mike Lazaridis to develop a pioneering new theoretical physics institute entirely from scratch.
