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.

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.

"Chemistry from First Principles" examines the appearance of matter in its most primitive form. It features the empirical rules of chemical affinity that regulate the synthesis and properties of molecular matter, analyzes the compatibility of the theories of chemistry with the quantum and relativity theories of physics, formulates a consistent theory based on clear physical pictures and manageable mathematics to account for chemical concepts such as the structure and stability of atoms and molecules. This text also explains the self-similarity between space-time, nuclear structure, covalent assembly, biological growth, planetary systems, and galactic conformation.

Damascius was head of the Neoplatonist academy in Athens when the Emperor Justinian shut its doors forever in 529. His work, Problems and Solutions Concerning First Principles, is the last surviving independent philosophical treatise from the Late Academy. Its survey of Neoplatonist metaphysics, discussion of transcendence, and compendium of late antique theologies, make it unique among all extant works of late antique philosophy. It has never before been translated into English. The Problems and Solutions exhibits a thorough?going critique of Proclean metaphysics, starting with the principle that all that exists proceeds from a single cause, proceeding to critique the Proclean triadic view of procession and reversion, and severely undermining the status of intellectual reversion in establishing being as the intelligible object. Damascius investigates the internal contradictions lurking within the theory of descent as a whole, showing that similarity of cause and effect is vitiated in the case of processions where one order (e.g. intellect) gives rise to an entirely different order (e.g. soul). Neoplatonism as a speculative metaphysics posits the One as the exotic or extopic explanans for plurality, conceived as immediate, present to hand, and therefore requiring explanation. Damascius shifts the perspective of his metaphysics: he struggles to create a metaphysical discourse that accommodates, insofar as language is sufficient, the ultimate principle of reality. After all, how coherent is a metaphysical system that bases itself on the Ineffable as a first principle? Instead of creating an objective ontology, Damascius writes ever mindful of the limitations of dialectic, and of the pitfalls and snares inherent in the very structure of metaphysical discourse.
