Roger Bacon's Philosophy of Nature

Bacon believed that an investigation of the behavior of light would lead to an understanding of nature's inner workings. The larger of the two treatises edited and translated in this book represents Bacon's best and fullest attempt to explore all of the implciations of this doctrine. The shorter work is an attempt to explore in detail the modes of propagation of light, a subject related to the larger issues treated in De multiplicatione specierum.
