Thomas Nagel 
What Does It All Mean? [PDF ebook] 
A Very Short Introduction to Philosophy

In this cogent and accessible introduction to philosophy, the 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. Although he states his own opinions clearly, Nagel leaves these fundamental questions open, allowing students to entertain other solutions and encouraging them to think for themselves.
