Of the many Schoolmen who read the pseudo-Aristotelian Secretum secretorum in the thirteenth century, none was more enthusiastic about this book than Roger Bacon. So highly did Bacon regard the Secretum that he prepared a redaction of the text, annotated it, and wrote an accompanying introductory treatise. Historians have long recognized the importance of Bacon's confrontation with the Secretum, but they have also misunderstood it. They have wrongly divided up Bacon's Secretum project between two widely separated dates. They have left (...) unasked the capital question of why Bacon undertook this project. More generally, they have fundamentally misjudged the place of the Secretum in Bacon's intellectual biography. Consequently, there are several distortions and gaps in the picture of Bacon's career currently circulating that deserve our critical attention. (shrink)
