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.

Descartes' characterisation of the mind as a 'thinking thing' marks the beginning of modern philosophy of mind. It is also the point of departure for Descartes' own system in which the mind is the first object of knowledge for those who reason in an 'orderly way'. This ground-breaking book shows that the Cartesian mind has been widely misunderstood: typically treated as simply the subject of phenomenal consciousness, ignoring its deeply intellectual character. James Hill argues that this interpretation has gone hand in hand with a misreading of Descartes' method of doubt which treats it as all-inclusive and universal in scope. In fact, the sceptical arguments of the First Meditation aim to lead the mind away from the senses and towards the intellectual 'notions' that the mind has within it, and which are never the subject of doubt. Hill also places Descartes' concept of mind into the wider setting of his science of nature, showing how he wished to reveal a mental subject that would able to comprehend the new physics necessitated by Copernicus' heliocentrism.

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.

"Descartes was the first to bring to light the idea of a transcendental science, which is to contain a system of knowledge of the conditions of possibility of all knowledge." - Kant A new 2023 translation directly from the original manuscripts into English of Descartes' famous work "Rules for the Direction of the Mind" (Règles pour la direction de l'esprit). This edition contains a new introduction and afterword from the translator, as well as a timeline of Descartes' life and summaries of each of his works. Here, Descartes lays out a method for approaching problems and seeking knowledge. The importance of this work lies in the fact that it established the scientific method as a way of investigating the world, and had a significant influence on the development of modern science. This work is one of the foundational texts of Western Philosophy

Descartes' ideas not only changed the course of Western philosophy but also led to or transformed the fields of metaphysics, epistemology, physics and mathematics, political theory and ethics, psychoanalysis, and literature and the arts. This book reprints Descartes' major works, Discourse on Method and Meditations, and presents essays by leading scholars that explore his contributions in each of those fields and place his ideas in the context of his time and our own. There are chapters by David Weissman on metaphysics and psychoanalysis, John Post on epistemology, Lou Massa on physics and mathematics, William T. Bluhm on politics and ethics, and Thomas Pavel on literature and art. These essays are accompanied by others by David Weissman and by Stephen Toulmin that introduce the idea of intellectual lineages, discuss the period in which Descartes wrote, and reexamine the premises of his philosophy in light of contemporary philosophical, political, and social thinking.

Is it possible to be certain of anything? If so, how? The father of modern philosophy and the founder of rational method in philosophical thought, René Descartes (1596–1650) sought the answers to these questions and in doing so, addressed the most important of methods of thinking and understanding truth. In Discourse on Method, he applies a scientific approach to philosophy that comprises four principles: to accept only what reason recognizes as "clear and distinct"; to analyze complex ideas by dividing them into smaller elements; to reconstruct the ideas; and to make accurate and complete enumerations of the data. His Meditations proceed according to this method, exploring the mind/body distinction, the nature of truth and error, the existence of God, and the essence of material things.
