This classic work, first published in 1912, has never been supplanted as an approachable introduction to the theory of philosophical enquiry. It gives Russell's views on such subjects as the distinction between appearance and reality, the existence and nature of matter, idealism, knowledge by acquaintance and by description, induction, truth and falsehood, the distinction between knowledge, error and probable opinion, and the limits and value of philosophical knowledge.

"The Value of Philosophy" is one of the most important chapters of Bertrand's Russell's magnum Opus, The Problems of Philosophy. As a whole, Russell focuses on problems he believes will provoke positive and constructive discussion, Russell concentrates on knowledge rather than metaphysics: If it is uncertain that external objects exist, how can we then have knowledge of them but by probability. There is no reason to doubt the existence of external objects simply because of sense data.

With the clarity that James deemed obligatory, Some Problems of Philosophy outlines his theory of perception. The early chapters expose the defects of intellectualism and monism and the advantages of empiricism and pluralism. The novelty that enters into concrete perceptual experience, and that is disallowed by the rationalizing intellect, suggests exciting possibilities. Denied any absolute truth in an ever-changing world, privy to only a piece of the truth at any given moment, the individual can, with faith and good will, help create order out of chaos. Some Problems in Philosophy, published posthumously, represents an important advance in William James’s thought.

A leading philosopher takes a mind-bending journey through virtual worlds, illuminating the nature of reality and our place within it. Virtual reality is genuine reality; that’s the central thesis of Reality+. In a highly original work of “technophilosophy,” David J. Chalmers gives a compelling analysis of our technological future. He argues that virtual worlds are not second-class worlds, and that we can live a meaningful life in virtual reality. We may even be in a virtual world already. Along the way, Chalmers conducts a grand tour of big ideas in philosophy and science. He uses virtual reality technology to offer a new perspective on long-established philosophical questions. How do we know that there’s an external world? Is there a god? What is the nature of reality? What’s the relation between mind and body? How can we lead a good life? All of these questions are illuminated or transformed by Chalmers’ mind-bending analysis. Studded with illustrations that bring philosophical issues to life, Reality+ is a major statement that will shape discussion of philosophy, science, and technology for years to come.

A fresh and original introduction to philosophy, written in a clear and entertaining style. The first part of the book presents philosophical problems, the second part contains solutions and further discussions.

We must all make choices about how we want to live. We evaluate our possibilities by relying on historical, moral, personal, political, religious, and scientific modes of evaluations, but the values and reasons that follow from them conflict. Philosophical problems are forced on us when we try to cope with such conflicts. There are reasons for and against all proposed ways of coping with the conflicts, but none of them has been generally accepted by reasonable thinkers. The constructive aim of The Nature of Philosophical Problems is to propose a way of understanding the nature of such philosophical problems, explain why they occur, why they are perennial, and propose a pluralist approach as the most reasonable way of coping with them. This approach is practical, context-dependent, and particular. It follows from it that the recurrence of philosophical problems is not a defect, but a welcome consequence of the richness of our modes of understanding that enlarges the range of possibilities by which we might choose to live. The critical aim of the book is to give reasons against both the absolutist attempt to find an overriding value or principle for resolving philosophical problems and of the relativist claim that reasons unavoidably come to an end and how we want to live is ultimately a matter of personal preference, not of reasons.

"This [text] is an introduction to some of the main problems of philosophy—the existence of God, the nature of the mind, human freedom, the limits of knowledge, and the truth about ethics. The chapters may be read independently of one another, but when read in order, they tell a more or less continuous story. We begin with some reflections on the life of Socrates and then go on to the existence of God, which is the most basic philosophical question, because our answer to it affects everything else. This leads naturally to a discussion of death and the soul, and then to more modern ideas about the nature of persons. The later chapters are about whether we can have objective knowledge in either science or ethics." -from the Preface Problems from Philosophy represents the final work of author and philosopher James Rachels. In it, he brings the same liveliness and clarity to the introduction of philosophy that he brings to his best-selling ethics text, The Elements of Moral Philosophy. This second edition has been revised by Rachels' son Stuart, who carefully has carefully refined his father's work to further strengthen its clarity and accessibility.
