The author’s final work, presented in a one-volume edition, is a rich, challenging analysis of man’s mental activity, considered in terms of thinking, willing, and judging.

    Heath's translation of the thirteen books of Euclid's Elements. In keeping with Green Lion's design commitment, diagrams have been placed on every spread for convenient reference while working through the proofs; running heads on every page indicate both Euclid's book number and proposition numbers for that page; and adequate space for notes is allowed between propositions and around diagrams. The all-new index has built into it a glossary of Euclid's Greek terms.Heath's translation has stood the test of time, and, as one done by a renowned scholar of ancient mathematics, it can be relied upon not to have inadvertantly introduced modern concepts or nomenclature. We have excised the voluminous historical and scholarly commentary that swells the Dover edition to three volumes and impedes classroom use of the original text. The single volume is not only more convenient, but less expensive as well.

    Though he never wrote down his thoughts, he had a brilliant pupil in Plato, who immortalized his teacher's legacy in 35 timeless dialogues that laid the philosophical basis for Western civilization.Professor Michael Sugrue of Princeton University brings the Socratic quest for truth alive in these lectures, which discuss ideas that are as vital today as they were 25 centuries ago. Ideas about truth, justice, love, beauty, courage, and wisdom. Ideas that can change lives and reveal the world in new ways to the true student.Professor Sugrue reveals the inner structure, action, and meaning of 17 of Plato's greatest dialogues, making this course an indispensable companion for anyone interested in philosophy in general or Platonic thought in particular.

    Descartes's Meditations on First Philosophy, the fundamental and originating work of the modern era in Western philosophy, is presented here in Donald Cress's completely revised edition of his well-established translation, bringing this version even closer to Descartes's original, while maintaining its clear and accessible style.

    Basing his assertions on the belief that knowledge is strictly relative to human interaction with the world, he considers the need for thought training, its use of natural resources, and its place in school conditions; inductive and deductive reasoning, interpreting facts, and concrete and abstract thinking; the functions of activity, language, and observation in thought training; and many other subjects.John Dewey’s influence on American education and philosophy is incalculable. This volume, as fresh and inspirational today as it was upon its initial publication a century ago, is essential for anyone active in the field of teaching or about to embark on a career in education.

    "A Treatise Concerning the Principles of Human Knowledge" is one of Berkeley's best known works and in it Berkeley expounds upon this idea of subjective idealism, which in other words is the idea that all of reality, as far as humans are concerned, is simply a construct of the way our brains perceive and according to Berkeley no other sense of reality matters beyond that which we perceive.

    It challenged the entire edifice of the philosophy and learning of Bacon's time, and left its mark on all subsequent discussions of scientific method. This volume presents a new translation of the text into modern English by Michael Silverthorne, together with an introduction by Lisa Jardine that sets the work in the context of Bacon's scientific and philosophical activities.

    The Structure of Scientific Revolutions is that kind of book. When it was first published in 1962, it was a landmark event in the history and philosophy of science. Fifty years later, it still has many lessons to teach. With The Structure of Scientific Revolutions, Kuhn challenged long-standing linear notions of scientific progress, arguing that transformative ideas don’t arise from the day-to-day, gradual process of experimentation and data accumulation but that the revolutions in science, those breakthrough moments that disrupt accepted thinking and offer unanticipated ideas, occur outside of “normal science,” as he called it. Though Kuhn was writing when physics ruled the sciences, his ideas on how scientific revolutions bring order to the anomalies that amass over time in research experiments are still instructive in our biotech age. This new edition of Kuhn’s essential work in the history of science includes an insightful introduction by Ian Hacking, which clarifies terms popularized by Kuhn, including paradigm and incommensurability, and applies Kuhn’s ideas to the science of today. Usefully keyed to the separate sections of the book, Hacking’s introduction provides important background information as well as a contemporary context.  Newly designed, with an expanded index, this edition will be eagerly welcomed by the next generation of readers seeking to understand the history of our perspectives on science.

    As a philosophy, however, it also denoted the striving after an independent state of mind and body, imperturbability, and reliance on sensory data as the true basis of knowledge.Epicurus (ca. 341-271 B.C.) founded one of the most famous and influential philosophical schools of antiquity. In these remains of his vast output of scientific and ethical writings, we can trace Epicurus' views on atomism, physical sensation, duty, morality, the soul, and the nature of the gods.

    Xenophon's portrait is the only one other than Plato's to survive, and while it offers a very personal interpretation of Socratic thought, it also reveals much about the man and his philosophical views. In 'Socrates' Defence' Xenophon defends his mentor against charges of arrogance made at his trial, while the 'Memoirs of Socrates' also starts with an impassioned plea for the rehabilitation of a wronged reputation. Along with 'The Estate-Manager', a practical economic treatise, and 'The Dinner-Party', a sparkling exploration of love, Xenophon's dialogues offer fascinating insights into the Socratic world and into the intellectual atmosphere and daily life of ancient Greece.

    His great book, On Nature, the world's first coherent philosophical treatise and touchstone for Plato, Aristotle, and Marcus Aurelius, has long been lost to history-but its surviving fragments have for thousands of years tantalized our greatest thinkers, from Montaigne to Nietzsche, Heidegger to Jung. Now, acclaimed poet Brooks Haxton presents a powerful free-verse translation of all 130 surviving fragments of the teachings of Heraclitus, with the ancient Greek originals beautifully reproduced en face.For more than seventy years, Penguin has been the leading publisher of classic literature in the English-speaking world.

     His starting point is moral intuition—the nearly instantaneous perceptions we all have about other people and the things they do. These intuitions feel like self-evident truths, making us righteously certain that those who see things differently are wrong. Haidt shows us how these intuitions differ across cultures, including the cultures of the political left and right. He blends his own research findings with those of anthropologists, historians, and other psychologists to draw a map of the moral domain. He then examines the origins of morality, overturning the view that evolution made us fundamentally selfish creatures. But rather than arguing that we are innately altruistic, he makes a more subtle claim—that we are fundamentally groupish. It is our groupishness, he explains, that leads to our greatest joys, our religious divisions, and our political affiliations. In a stunning final chapter on ideology and civility, Haidt shows what each side is right about, and why we need the insights of liberals, conservatives, and libertarians to flourish as a nation.

    J. Ayer in a fabled debate about the existence of God and the possibility of metaphysics, knew that seminary students were fed a woefully inadequate diet of theses and proofs, and that their familiarity with most of history's great thinkers was reduced to simplistic caricatures. Copleston set out to redress the wrong by writing a complete history of Western philosophy, one crackling with incident and intellectual excitement -- and one that gives full place to each thinker, presenting his thought in a beautifully rounded manner and showing his links to those who went before and to those who came after him. The result of Copleston's prodigious labors is a history of philosophy that is unlikely ever to be surpassed. Thought magazine summed up the general agreement among scholars and students alike when it reviewed Copleston's A History of Philosophy as "broad-minded and objective, comprehensive and scholarly, unified and well proportioned... We cannot recommend [it] too highly."

    Ideal for anyone who wants to read a great work for the first time or revisit an old favorite, these new editions open the door to the stories and ideas that have shaped our world.

    in the eastern outreaches of the Roman Empire. Sold as a child and crippled from the beatings of his master, Epictetus was eventually freed, rising from his humble roots to establish an influential school of Stoic philosophy. Stressing that human beings cannot control life, only how they respond to it, Epictetus dedicated his life to outlining the simple way to happiness, fulfillment, and tranquility. By putting into practice the ninety-three witty, wise, and razor-sharp instructions that make up The Art of Living, readers learn to successfully meet the challenges of everyday life and face life's inevitable losses and disappointments with grace. Epictetus's teachings rank among the greatest wisdom texts of human civilization. Sharon Lebell presents this esteemed philosopher's invaluable insights for the first time in a splendidly down-to-earth rendition. The result is the West's first and best primer for living the best possible life -- as helpful in the twenty-first century as it was in the first.
