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).

"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.

Two works from the father of modern philosophy. In Discourse on Method, he formulated a scientific approach comprising four principles, including to accept only what reason recognizes as "clear and distinct." In Meditations, he explores the mind/body distinction, the nature of truth and error, the existence of God, and the essence of material things.

Descartes is possibly the most famous of all writers on the mind, but his theory of mind has been almost universally misunderstood, because his philosophy has not been seen in the context of his scientific work. Desmond Clarke offers a radical and convincing rereading, undoing the received perception of Descartes as the chief defender of mind/body dualism. For Clarke, the key is to interpret his philosophical efforts as an attempt to reconcile his scientific pursuits with the theologically orthodox views of his time.

Descartes’s concern with the proper method of belief formation is evident in the titles of his works—e.g., The Search after Truth, The Rules for the Direction of the Mind and The Discourse on Method of rightly conducting one’s reason and seeking the truth in the sciences. It is most apparent, however, in his famous discussions, both in the Meditations and in the Principles, of one particularly noteworthy source of our doxastic errors—namely, the misuse of one’s will. What is not widely recognized, let alone appreciated and understood, is the relationship between his concern with belief formation and his concern with virtue. In fact, few seem to realize that Descartes regards doxastic errors as moral errors and as sins both because such errors are intrinsically vicious and because they entail notably deleterious social consequences. Reforming the Art of Living seeks to rectify this rather common oversight in two ways. First, it aims to elucidate the nature of Descartes’s account of virtuous belief formation. Second, it aims both (i) to illuminate the social significance of Descartes’s philosophical program as it relates to the understanding and practice not of science, but of religion and (ii) to develop a kind of Leibnizian critique of this aspect of his program. More specifically, it aims to show that Descartes’s project is “dangerous,” insofar as it is subversive not only of traditional Christianity but also of other traditional forms of religion, both in theory and in practice.

'I realized it was necessary to demolish everything and start again right from the foundations, if I wanted to establish anything in the sciences that was stable and likely to last.' Ren Descartes Revered as the 'father of modern philosophy', Descartes is one of the most influential philosophers of all time, but his ideas are also highly controversial and have been subjected to intense criticism by present-day philosophers. John Cottingham examines Descartes's remarkable attempt to construct a new basis for scientific understanding, his famous first principle, 'I am thinking, therefore I exist,' and his notorious and often misunderstood account of the relation between mind and body. He also tackles fascinating and lesser-known aspects of Descartes's philosophy, including his views on language, human and animal nature, the role of the emotions in the good life, and the place of God in science and ethics. Extracts are taken from the whole range of Descartes's writings, including the Discourse on the Method, Meditations on First Philosophy, Principles of Philosophy and his last book, the Passions of the Soul, as well as extracts from his philosophical letters.
