Each of the 17 chapters of this book is an introduction to the life and beliefs of a great scientist, philosopher, poet or thinker who rejects faith in theistic concepts of religion developed by primitive people. They run from Voltaire, Thomas Paine and Robert Ingersoll, to Walt Whitman, Isaac Asimov and Carl Sagan. These thinkers expound on their views of the natural world and on what we can hope and believe based on the scientific method and discoveries. They fill us with overwhelming sense of wonder and awe by what they teach about how to view our wonderful world. They teach us to thrill to evolving life and to be at peace with ourselves despite the limits of our lives. Past President of the Humanist Association of Central Connecticut, Dr. David Schafer, said, "For several years, among the talks most consistently popular with our members have been those in Doug Peary4s long running series, 4Humanist Heroes.4 One reason seems to be the emotional intensity Doug brings to his research on each of his subjects, an intensity that continues to reward him, and us, deeply with each of his subjects with each new biography he touches. These are not just interesting stories from and about the lives of Humanists--they are intimate glimpses of more meaningful insights into living, working, loving, and dying, profoundly inspirational for Doug and his audiences."
