offers students and general readers a uniquely straightforward yet challenging introduction to fundamental philosophical problems. Readily accessible to novices yet rich enough for more experienced readers, it combines serious investigation across a wide range of subjects in analytic philosophy with a clear, user-friendly writing style. Topics include logic and reasoning, the theory of knowledge, the nature of the external world, the mind/body problem, normative ethics, metaethics, free will, the existence of God, and the problem of evil. A concluding chapter outlines the worldview developed in the text and connects that view to questions about the meaning of life. The interconnection of philosophical problems and the relationship of philosophy and science are emphasized throughout. The book includes both extensive quotes from historical figures such as Aquinas, Descartes, and Hume and references to philosophically minded nonphilosophers like Dostoevski, Stephen Jay Gould, and Carl Sagan. is designed for use in introductory philosophy courses at a wide range of institutions. It contains numerous pedagogical materials at the end of each chapter: sections called "misconceptions" list errors that introductory readers should avoid; guide questions prompt students to explain in their own words what the text is saying; review questions help students prepare for examinations; open-ended discussion questions call for independent judgment; and annotated bibliographies provide suggestions for further reading. The volume is further enhanced by a list of famous quotations from philosophers, a glossary of philosophical terms, a glossary of names of the most famous philosophers and scientists discussed in the text, and an extensive bibliography listing every work cited.
