Volume XI of The Oxford Francis Bacon comprises the first new critical edition of Bacon's most important philosophical work, the Novum Organum, for a hundred years. One of the foundation documents of early-modern philosophy, Novum Organum is edited in accordance with modern textual-criticalprinciples for the first time. Graham Rees presents the only edition ever to include the original Latin text with a brand new, facing-page translation, and a thorough Introduction and detailed commentary of the text. The edition represents a major step towards the reinstatement of Bacon as a centralfigure in the history of early-modern philosophy, and will be essential reading for anyone studying the history of science and ideas in the seventeenth-century.
