The biography of Sir john Templeton, who has dedicated his life to advancing the scientific study of spiritual realities has been revised and updated. Now in his 91st year, Sir John Templeton is an inspiring and motivational force both through his personal example and through the foundation that bears his name and is dedicated to his mission. This volume reviews the life of this man of vision, from his childhood in rural Tennessee, to his education at Yale and Oxford, to his legendary years on Wall Street, the birth of his children and the development and growth of "humanity theology science." Interwoven with the stories and facts are the roots of his faith and the values that he credits for his financial success which form the catalyst for his lifelong mission. Sir John's commitment, which is, also, the mission of the John Templeton Foundation, is to encourage a major scientific effort to obtain solid empirical data about spiritual realities such as love, purpose, creativity, intellect, thanksgiving, prayer, humility, praise, thrift, compassion, invention, truthfulness, giving and worship. This second edition of his biography updates the growth of the many and varied programmes of the John Templeton Foundation that support this mission. It, also, introduces some of the scientists, theologians, philosophers, writers and fellow investors who now serve as staff and advisors to the John Templeton Foundation, striving toward Sir John's goal of one hundred fold more spiritual information gained through the application of scientific methodology and analysis.
