This is the second edition of the book originally crafted by my dear friend, mentor and now member of the great cloud of witnesses, Dr. Joseph J. Bohac.For both Doc Bohac and myself, much of our understanding of human development comes from being acutely interested in people. We were/are observers, and we have studied much in this dynamic field. That being said, we are not really academics...more practitioners, and we have written this book to be read by students who may not do much additional study in the field of Human Development than this work. Thus, though we believe it is scholarly, it is not written for the advanced scholar, but the average person who is also fascinated with God's special creation...mankind. "
