In this Handbook twenty-six leading scholars survey the development of philosophy between the middle of the sixteenth century and the early eighteenth century. The five parts of the book cover metaphysics and natural philosophy; the mind, the passions, and aesthetics; epistemology, logic, mathematics, and language; ethics and political philosophy; and religion. The period between the publication of Copernicus's De Revolutionibus and Berkeley's reflections on Newton and Locke saw one of the most fundamental changes in the history of our way of thinking about the universe. This radical transformation of worldview was partly a response to what we now call the Scientific Revolution; it was equally a reflection of political changes that were no less fundamental, which included the establishment of nation-states and some of the first attempts to formulate a theory of international rights and justice. Finally, the Reformation and its aftermath undermined the apparent unity of the Christian church in Europe and challenged both religious beliefs that had been accepted for centuries and the interpretation of the Bible on which they had been based. The Handbook surveys a number of the most important developments in the philosophy of the period, as these are expounded both in texts that have since become very familiar and in other philosophical texts that are undeservedly less well-known. It also reaches beyond the philosophy to make evident the fluidity of the boundary with science, and to consider the impact on philosophy of historical and political events-explorations, revolutions and reforms, inventions and discoveries. Thus it not only offers a guide to the most important areas of recent research, but also offers some new questions for historians of philosophy to pursue and to have indicated areas that are ripe for further exploration.

George Berkeley (1685-1753) was a university teacher, a missionary, and later a Church of Ireland bishop. The over-riding objective of his long philosophical career was to counteract objections to religious belief that resulted from new philosophies associated with the Scientific Revolution. Accordingly, he argued against scepticism and atheism in the Principles and the Three Dialogues; he rejected theories of force in the Essay on Motion; he offered a new theory of meaning for religious language in Alciphron; and he modified his earlier immaterialism in Siris by speculating about the body's influence on the soul. His radical empiricism and scientific instrumentalism, which rejected the claims of the sciences to provide a realistic interpretation of phenomena, are still influential today. This edition provides texts from the full range of Berkeley's contributions to philosophy, together with an introduction by Desmond M. Clarke that sets them in their historical and philosophical contexts.

‘I shall imagine myself as if I had no hands, no eyes, no flesh, no blood, no senses at all’

Descartes was prepared to go to any lengths in his search for certainty – even to deny those things that seemed most self-evident. In his Meditations of 1641, and in the Objections and Replies that were included with the original publication, he set out to dismantle and then reconstruct the idea of the individual self and its existence. In doing so, Descartes developed a language of subjectivity that has lasted to this day and also took his first steps towards the view that would eventually be expressed in the epigram Cogito, ergo sum (‘I think, therefore I am’), one of modern philosophy’s most famous – and most fiercely controversial – claims.

The first part of a two-volume edition of Descartes’ works in Penguin Classics, this edition includes extensive selections from the Objections and Replies, Part One of The Principles of Philosophy, Comments on a Certain Manifesto and related correspondence from 1643–9.

Widely regarded as the father of modern Western philosophy, Descartes sought to look beyond established ideas and create a thought system based on reason. In this profound work he meditates on doubt, the human soul, God, truth and the nature of existence itself. GREAT IDEAS. Throughout history, some books have changed the world. They have transformed the way we see ourselves - and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives - and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are.

Descartes' Discourse on Method has long been regarded as a seminal contribution to modern philosophy. We can now see that it is also one of the key texts in the ‘scientific revolution’ of the seventeenth century.

René Descartes (1596–1650) did major research in optics, geometry, astronomy and physiology, although (partly because Galileo had just been condemned by the Inquisition) he published nothing until he was over forty. The Discourse forms the preface to his first collection of scientific papers (1637), sketching in a new method based on hypothesis and deduction which was soon to replace traditional techniques derived from Aristotle. This edition puts the work in context, by including extracts from Descartes’ correspondence, the Rules for Guiding One’s Intelligence and from The World – a posthumously published summary of his physical theories, which at one point in its chequered life had to be rescued from the river Seine. The age of Newton marks one of the great turning points in intellectual history; Descartes has a key place at its very heart.

A companion volume Meditations and other Metaphysical Writings by Descartes is also published in Penguin Classics.

A new translation of Voltaire's Treatise on Toleration, one of the most important essays on religious tolerance and freedom of thought A powerful, impassioned case for the values of freedom of conscience and religious tolerance, Treatise on Toleration was written after the Toulouse merchant Jean Calas was falsely accused of murdering his son and executed on the wheel in 1762. As it became clear that Calas had been persecuted by 'an irrational mob' for being a Protestant, the Enlightenment philosopher Voltaire began a campaign to vindicate him and his family. The resulting work, a screed against fanaticism and a plea for understanding, is as fresh and urgent today as when it was written.

Although Rene Descartes' (1596-1650) is best remembered today for writing "I think, therefore, I am," his unique contribution to the history of ideas was his effort to construct a philosophy that would be sympathetic to the new sciences that emerged in the seventeenth century. In four major publications, he fashioned a philosophical system that accommodated the needs of these new sciences, thereby earning the unrelenting hostility of both Catholic and Calvinist theologians, who relied on the scholastic philosophy that Descartes hoped to replace. His contemporaries claimed that his proofs of God's existence, in the Meditations, were so unsuccessful that he must have been a cryptic atheist, and that his discussion of skepticism served merely to fan the flames of libertinism. Although Descartes died in Stockholm in obscurity, he soon became one of the most famous philosophers of the seventeenth century, a status that he continues to enjoy today. This English-language biography addresses the complete range of Descartes' interests in theology, philosophy, and the sciences, and traces his intellectual development throughout his entire career. Desmond M. Clarke is Professor of Philosophy at University College Cork, Ireland, where he previously served as Dean of Arts and Vice-President. He is author of a number of books on Descartes and the seventeenth century, including Descartes' Philosophy of Science (1982), Occult Powers & Hypotheses (1989) and Descartes' Theory of Mind (1993). He has translated two selections of Descartes' writings and has also translated La Forge's Treatise on the Human Mind (1997) and Poulain de la Barre's The Equality of the Sexes.

Rene Descartes is best remembered today for writing 'I think, therefore I am', but his main contribution to the history of ideas was his effort to construct a philosophy that would be sympathetic to the new sciences that emerged in the seventeenth century. To a great extent he was the midwife to the Scientific Revolution and a significant contributor to its key concepts. In four major publications, he fashioned a philosophical system that accommodated the needs of these new sciences and thereby earned the unrelenting hostility of both Catholic and Calvinist theologians, who relied on the scholastic philosophy that Descartes hoped to replace. His contemporaries claimed that his proofs of God's existence in the Meditations were so unsuccessful that he must have been a cryptic atheist and that his discussion of skepticism served merely to fan the flames of libertinism. This is the first biography in English that addresses the full range of Descartes' interest in theology, philosophy and the sciences and that traces his intellectual development through his entire career.
