"In the Fire of the Heart" is the biggest and prettiest of those fine "Life Books" by Ralph Waldo Trine. And some say it's the best-which is saying a good deal. This book deals with cosmic things, love, life, beautiful living, socialism and "agencies whereby we shall secure the people's greatest good." The author has collected a vast quantity of statistics and quotable facts upon social conditions in America, and woven them together in the web of his own enthusiasm for humanity.
