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.

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.

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.

In this concise text, Roy Bhaskar sets out to diagnose, explain and resolve the "problems of philosophy". Plato Etc. reviews all the main areas of the subject: the theory of knowledge and philosophy of science; the philosophy of logic and language; the philosophies of space, time and causality; the philosophy of the social and life sciences and of dialectic; ethics, politics and aesthetics; and the history and sociology of philosophy. Among the issues discussed are the problems of induction and universals, the question of relativism, Heidegger’s "scandal of philosophy" (the search for a proof of the reality of the external world), the nature of moral truth and the conundrum of free will and determinism. The last two chapters consist of a synoptic account of the development of Western philosophy from the pre-Socratics to poststructuralism. Plato Etc. seeks to revindicate the philosophical project, and to demonstrate that the author’s "dialectical critical realism" has the categorical power to remedy the problem fields of philosophy. The book serves both as a critical introduction to philosophy and as an invaluable resource for the scholar.
