Rene Descartes discusses the basic rules he has devised to guide human thought toward better knowledge.

    The central concept of his philosophy is found in a careful discrimination between the awareness of objects independent of our perception and the awareness of essences attributed to objects by our mind, or between what Santayana calls the realm of existents and the realm of subsistents. Since we can never be certain that these attributes actually inhere in a substratum of existents, skepticism is established as a form of belief, but animal faith is shown to be a necessary quality of the human mind. Without this faith there could be no rational approach to the necessary problem of understanding and surviving in this world.Santayana derives this practical philosophy from a wide and fascinating variety of sources. He considers critically the positions of such philosophers as Descartes, Euclid, Hume, Kant, Parmenides, Plato, Pythagoras, Schopenhauer, and the Buddhist school as well as the assumptions made by the ordinary man in everyday situations. Such matters as the nature of belief, the rejection of classical idealism, the nature of intuition and memory, symbols and myth, mathematical reality, literary psychology, the discovery of essence, sublimation of animal faith, the implied being of truth, and many others are given detailed analyses in individual chapters.

    He approaches his subject through a discussion of language, the relationships of truth to experience and an investigation into how knowledge of the structure of language helps our understanding of the structure of the world.This edition includes a new introduction by Thomas Baldwin, Clare College, Cambridge

    His contributions have had a profound impact on almost every philosophical movement that followed him. His teachings on religion were unorthodox in that they were based on rationality rather than revelation. Tho logically proving God's existence might be impossible, it's morally reasonable to "act as if there be a God." His strictly rational approach was considered so scandalous that the King of Prussia forbid him to teach or write further on religious subjects, which Kant obeyed until the king's death. A work of major importance in the history of Western religious thought, Religion Within the Limits of Reason Alone represents a great philosopher's attempt to spell out the form & content of a type of religion grounded in moral reason & meeting the needs of an ethical life.

    Challenging Locke's views in Essays on Human Understanding chapter by chapter, Leibniz's references to his contemporaries and his discussion of the ideas and institutions of the age make this work a fascinating and valuable document in the history of ideas.

    One meaning is the effect of certain ideas in promoting the slow drift of mankind towards civilization. This is the Adventure of Ideas in the history of mankind. The other meaning is the author's adventure in framing a speculative scheme of ideas which shall be explanatory of the historical adventure.

    The subjects treated include Abraham, Angel and Anthropophages; Baptism, Beauty and Beasts; Fables, Fraud and Fanaticism; Metempsychosis, Miracles and Moses; all of them exposed to Voltaire's lucid scrutiny, his elegant irony and his passionate love of reason and justice.

    It is also one of the best introductions to Deleuze's thought, establishing many of his central philosophical positions.In Nietzsche and Philosophy, Deleuze identifies and explores three crucial concepts in Nietzschean thought-multiplicity, becoming, and affirmation-and clarifies Nietzsche's views regarding the will to power, eternal return, nihilism, and difference. For Deleuze, Nietzsche challenged conventional philosophical ideas and provided a means of escape from Hegel's dialectical thinking, which had come to dominate French philosophy. He also offered a path toward a politics of difference. In this new edition, Michael Hardt's foreword examines the profound influence of Deleuze's provocative interpretations on the study of Nietzsche, which opened a whole new avenue in postwar thought.

    The unstated objective of his lecture (“Existentialism Is a Humanism”) was to expound his philosophy as a form of “existentialism,” a term much bandied about at the time. Sartre asserted that existentialism was essentially a doctrine for philosophers, though, ironically, he was about to make it accessible to a general audience. The published text of his lecture quickly became one of the bibles of existentialism and made Sartre an international celebrity.The idea of freedom occupies the center of Sartre’s doctrine. Man, born into an empty, godless universe, is nothing to begin with. He creates his essence—his self, his being—through the choices he freely makes (“existence precedes essence”). Were it not for the contingency of his death, he would never end. Choosing to be this or that is to affirm the value of what we choose. In choosing, therefore, we commit not only ourselves but all of mankind.This book presents a new English translation of Sartre’s 1945 lecture and his analysis of Camus’s The Stranger, along with a discussion of these works by acclaimed Sartre biographer Annie Cohen-Solal. This edition is a translation of the 1996 French edition, which includes Arlette Elkaïm-Sartre’s introduction and a Q&A with Sartre about his lecture.

    Drawing on examples from many fields, it explains how scientists analyze and choose their working facts, and it explores the nature of experimentation, theory, and the mind. 1914 edition.

    In 1943, the final year of her life, unable to join the resistance movement in France, she worked in London for the Free French government in exile. Here she was commissioned to outline a plan for the renewal of Europe after the scourge of Nazism. The Need for Roots was the direct result. In it she seized the opportunity to denounce the false values of contemporary civilisation. In the cult of materials she witnessed a devastating loss of spirit and consequently of human values. To counteract this she sets out a radical vision for spiritual and political renewal with a passion for truth which sweeps through these pages. The book has become a lasting spiritual testament for our age, where we are confronted, as T.S. Eliot comments, by a 'genius akin to that of the saints'.

    In the three years that followed, Luther clarified and defended his position in numerous writings. Chief among these are the three treatises written in 1520. In these writings Luther tried to frame his ideas in terms that would be comprehensible not only to the clergy but to people from a wide range of backgrounds. [i]To the Christian Nobility of the German Nation[/i] is an attack on the corruption of the church and the abuses of its authority, bringing to light many of the underlying reasons for the Reformation. The second treatise, [i]The Babylonian Captivity of the Church[/i], contains Luther's sharp criticism of the sacramental system of the Catholic church. [i[The Freedom of a Christian[/i] gives a concise presentation of Luther's position on the doctrine of justification by faith. The translations of these treatises are all taken from the American edition of Luther's Works. This new edition of [i]Three Treatises[/i] will continue to be a popular resource for individual study, church school classes, and college and seminary courses.

    This Penguin Classics edition of The Complete Essays is translated from the French and edited with an introduction and notes by M.A. Screech.In 1572 Montaigne retired to his estates in order to devote himself to leisure, reading and reflection. There he wrote his constantly expanding 'assays', inspired by the ideas he found in books contained in his library and from his own experience. He discusses subjects as diverse as war-horses and cannibals, poetry and politics, sex and religion, love and friendship, ecstasy and experience. But, above all, Montaigne studied himself as a way of drawing out his own inner nature and that of men and women in general. The Essays are among the most idiosyncratic and personal works in all literature and provide an engaging insight into a wise Renaissance mind, continuing to give pleasure and enlightenment to modern readers.With its extensive introduction and notes, M.A. Screech's edition of Montaigne is widely regarded as the most distinguished of recent times.Michel de Montaigne (1533-1586) studied law and spent a number of years working as a counsellor before devoting his life to reading, writing and reflection.If you enjoyed The Complete Essays, you might like Francois Rabelais's Gargantua and Pantagruel, also available in Penguin Classics.'Screech's fine version ... must surely serve as the definitive English Montaigne'A.C.
