Descartes occupies a position of pivotal importance as one of the founding fathers of modern philosophy; he is, perhaps the most widely studied of all philosophers. In this authoritative collection an international team of leading scholars in Cartesian studies present the full range of Descartes' extraordinary philosophical achievement. His life and the development of his thought, as well as the intellectual background to and reception of his work, are treated at length. At the core of the volume are a group of chapters on his metaphysics: the celebrated 'Cogito' argument, the proofs of God's existence, the 'Cartesian circle' and the dualistic theory of the mind and its relation to his theological and scientific views. Other chapters cover the philosophical implications of his work in algebra, his place in the seventeenth-century scientific revolution, the structure of his physics, and his work on physiology and psychology.

Since Descartes famously proclaimed, "I think, therefore I am," science has often overlooked emotions as the source of a person’s true being. Even modern neuroscience has tended, until recently, to concentrate on the cognitive aspects of brain function, disregarding emotions. This attitude began to change with the publication of Descartes’ Error in 1995. Antonio Damasio—"one of the world’s leading neurologists" (The New York Times)—challenged traditional ideas about the connection between emotions and rationality. In this wondrously engaging book, Damasio takes the reader on a journey of scientific discovery through a series of case studies, demonstrating what many of us have long suspected: emotions are not a luxury, they are essential to rational thinking and to normal social behavior.

Plotinus is the first Greek philosopher to hold a systematic theory of consciousness. The key feature of his theory is that it involves multiple layers of experience: different layers of consciousness occur in different levels of self. This layering of higher modes of consciousness on lower ones provides human beings with a rich experiential world, and enables human beings to draw on their own experience to investigate their true self and the nature of reality. This involves a robust notion of subjectivity. However, it is a notion of subjectivity that is unique to Plotinus, and remarkably different from the Post-Cartesian tradition. Behind the plurality of terms Plotinus uses to express consciousness, and behind the plurality of entities to which Plotinus attributes consciousness (such as the divine souls and the hypostases), lies a theory of human consciousness. It is a Platonist theory shaped by engagement with rival schools of ancient thought.

The Philosophical Roots of the Ecological Crisis: Descartes and the Modern Worldview traces the conceptual sources of the present environmental degradation within the worldview of Modernity, and particularly within the thought of René Descartes, universally acclaimed as the father of modern philosophy. The book demonstrates how the triple foundations of the Modern worldview – in terms of an exaggerated anthropocentrism, a mechanistic conception of the natural world, and the metaphysical dualism between humanity and the rest of the physical world – can all be largely traced back to Cartesian thought, with direct ecological consequences.

Fourteen new essays trace the historical development of the distinction between primary and secondary qualities, a key topic in metaphysics, epistemology, and philosophy of perception. The volume starts with the ancient Greeks, discusses virtually all major figures of the early modern era, and reflects on the place of the topic in philosophy today.
