Descartes thought that we could achieve absolute certainty by starting with radical doubt. He adopts this strategy in the Meditations on First Philosophy, where he raises sweeping doubts with the famous dream argument and the hypothesis of an evil demon. But why did Descartes think we should take these exaggerated doubts seriously? And if we do take them seriously, how did he think any of our beliefs could ever escape them? Janet Broughton undertakes a close study of Descartes's first three meditations to answer these questions and to present a fresh way of understanding precisely what Descartes was up to. Broughton first contrasts Descartes's doubts with those of the ancient skeptics, arguing that Cartesian doubt has a novel structure and a distinctive relation to the commonsense outlook of everyday life. She then argues that Descartes pursues absolute certainty by uncovering the conditions that make his radical doubt possible. She gives a unified account of how Descartes uses this strategy, first to find certainty about his own existence and then to argue that God exists. Drawing on this analysis, Broughton provides a new way to understand Descartes's insistence that he hasn't argued in a circle, and she measures his ambitions against those of contemporary philosophers who use transcendental arguments in their efforts to defeat skepticism. The book is a powerful contribution both to the history of philosophy and to current debates in epistemology.

In 'Descartes's Method of Doubt', Broughton analyses Descartes's novel way of raising radical doubt and argues that he thought he could use doubt to achieve certainty by uncovering the conditions that make radical doubt possible.

Tarek Dika presents a systematic account of Descartes' method and its efficacy. He develops an ontological interpretation of Descartes's method as a dynamic and, within limits, differentiable problem-solving cognitive disposition or habitus, which can be actualized or applied to different problems in various ways, depending on the nature of the problem. Parts I-II of the book develop the foundations of such an habitual interpretation of Descartes's method, while Parts III-V demonstrate the fruits of such an interpretation in metaphysics, natural philosophy, and mathematics. This is the first book to draw on the recently-discovered Cambridge manuscript of Descartes's Rules for the Direction of the Mind (1620s): it gives a concrete demonstration of the efficacy of Descartes's method in the sciences and of the underlying unity of Descartes's method from Rules for the Direction of the Mind to Principles of Philosophy (1644).

This is an English translation of Descartes' seminal discourse, with an original essay by Richard Kennington. This text is designed to provide the student with a close translation, notes, and a glossary of key terms, facilitating access to ideas as they originally were presented and helping to make the translator's work transparent. Focus Philosophical Library translations are close to and are non-interpretative of the original text, with the notes and a glossary intending to provide the reader with some sense of the terms and the concepts as they were understood by Decartes' immediate audience. The Focus Philosophical Library publishes clear, faithful editions enabling access for modern students to the essential ideas and wisdom of the world’s greatest thinkers.

"It is not enough to have a good mind; it is more important to use it well" René Descartes was a central figure in the scientific revolution of the seventeenth century. In his Discourse on Method he outlined the contrast between mathematics and experimental sciences, and the extent to which each one can achieve certainty. Drawing on his own work in geometry, optics, astronomy and physiology, Descartes developed the hypothetical method that characterizes modern science, and this soon came to replace the traditional techniques derived from Aristotle. Many of Descartes’ most radical ideas—such as the disparity between our perceptions and the realities that cause them—have been highly influential in the development of modern philosophy. This edition sets the Discourse on Method in the wider context of Descartes’ work, with the Rules for Guiding One’s Intelligence in Searching for the Truth (1628), extracts from The World (1633) and selected letters from 1636-9. A companion volume, Meditations and Other Metaphysical Writings, is also published in Penguin Classics.

I perceived it to be possible to arrive at knowledge highly useful in life; and in room of the Speculative Philosophy usually taught in the Schools, to discover a Practical, by means of which, knowing the force and action of fire, water, air, the stars, the heavens, and all the other bodies that surround us, as distinctly as we know the various crafts of our artizans, we might also apply them in the same way to all the uses to which they are adapted, and thus render ourselves the lords and possessors of nature. from Part VI of Discourse on the Method Sometimes called the father of modern philosophy, French mathematician, scientist, and writer RENE DESCARTES (15961650) continues to have a deeply profound impact on our modern world. His thinking on how the mind works and what is it capable of has profoundly impacted our understanding of ourselveshe summed up his philosophy with the phrase I think, therefore I am, which still thrills usand his influence extends to our own experiments with modern computing and artificial intelligence. Here, in one volume, are two of the great thinkers most significant works: [ Discourse on the Method was written in French and first published in 1637 under the full title Discourse on the Method of Rightly Conducting the Reason, and Seeking Truth in the Sciencesits treatise on the value of doubt and skepticism when studying the natural world laid the foundation for the modern scientific method as we still employ it today. [ Meditations, originally subtitled In which the existence of God and the immortality of the soul are demonstrated, was written in Latin and first published in 1641here, Descartes considers that nature of the human mind, how we can know whatwe know, and the essence of material things. Essential reading for understanding both todays science and todays philosophy, these foundational works are here presented in the 1901 edition of the 1850 English translations by Scottish poet, philosopher, and historian JOHN VEITCH (18291894).
