Legend may have transformed the thirteenth-century English friar Roger Bacon into the Faust-like sorcerer Doctor Mirabilis, but he stands today in high regard as Europe's first great pioneer in the field of science. Bypassing the vicissitudes of Bacon's reputation, this definitive new biography by science writer Brian Clegg places the medieval monastic firmly in the turbulent and contentious intellectual atmosphere of his day. It also finds in Bacon's attempt to reconcile, or at least acknowledge, the variant methods and means of science and theology a quest that places him well ahead of his intellectual times. For Bacon brought to his inquiry into the nature of things his gifts not only as a lucid observer of natural phenomena, rigorous experimenter, empirical thinker, and gifted mathematician but as a theologian and philosopher as well. In his search for truth he would, like Galileo, suffer imprisonment rather than sacrifice his intellectual integrity. From Bacon's popularity as a teacher at Oxford and Paris, through his innovations in calendar reform, his experiments in optics, his designs for a flying machine, and, most famously, his development of the principle of inductive experimental science, this illuminative volume unfolds the story of a brilliant career.
