Can an atheist believe that life has meaning? Where do his values come from and are they different from those who believe in God or Spirit? Can he view all life as sacred and interconnected? If he doesn't believe in God, is he free of guilt? These are among the questions addressed in this small book. Written by an atheist, Is God Really Necessary? shares the author's progression from being a religious believer to being a nonbeliever. He outlines his materialist philosophy and its implications for topics such as belief in spirit, or development of a value system. The book is written in an informal personal style, but contains more formal arguments for the material point of view in the appendices.
