The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete.

Distinguished author of Mortal Questions and The View from Nowhere sets forth the central problems of philosophical inquiry for the beginning student. Arguing that the best way to learn about philosophy is to think about its questions directly, Thomas Nagel considers possible solutions to nine problems - knowledge of the world beyond our minds, knowledge of other minds, the mind-body problem, free will, the basis of morality, right and wrong, the nature of death, the meaning of life, and the meaning of words.

"Consciousness is what makes the mind-body problem really intractable." So begins Thomas Nagel's classic 1974 essay "What is it Like to be a Bat?" Nagel's essay initiated the now widespread attention to consciousness as a central problem for philosophy, psychology, and neuroscience; it also influenced the recognition of the consciousness of nonhuman creatures as an important subject of study.

This book offers what may with reservations be described as a theory of the mind. But it does not give new information about minds. We possess already a wealth of information about minds, information which is neither derived from, nor upset by, the arguments of philosophers. The philosophical arguments which constitute this book are intended not to increase what we know about minds, but to rectify the logical geography of the knowledge which we already possess.

In 1943, Jean-Paul Sartre published his masterpiece, Being and Nothingness, and laid the foundation of his legacy as one of the greatest twentieth century philosophers. A brilliant and radical account of the human condition, Being and Nothingness explores what gives our lives significance. In a new and more accessible translation, this foundational text argues that we alone create our values and our existence is characterized by freedom and the inescapability of choice.
