What is the purpose of life on Earth? Philosopher Jacob Needleman frames man's role on the planet in a completely new and fresh way, moving beyond the usual environmental concerns to reveal how the care and maintenance of a world is something vital and basic to our existence as authentic human beings. In some of his most deeply affecting writing, Needleman draws on his childhood experiences with a terminally ill friend whose impending death forces the young boys to face questions and the meaning of existence at an early age-questions that Needleman carried with him in his explorations of science and philosophy throughout his career as a scholar of religions. The conclusions that he reaches will give all of us a new sense of the purpose of our lives and the planet we live on.
