This groundbreaking study of Roger Bacon, the 13th-century Franciscan scholar and philosopher, explores his lifelong quest for a "universal science" that would reconcile reason with revelation. Easton argues that Bacon's work laid the foundation for modern scientific inquiry by insisting on the importance of empirical observation and systematic experimentation. Along the way, Easton provides a fascinating glimpse into Bacon's life and times, from his encounters with Pope Clement IV and King Edward I to his interest in alchemy and astronomy. A must-read for anyone interested in the history of science and philosophy.
