Abstract

This thesis examines Roger Bacon's contribution to experimental science under four headings: in relation to Bacon's life and chronology, the place of this science in his reform of studies, Bacon's doctrinal account of scientia experimentalis, a newly edited text of Opus maius, part six, on experimental science. The correlation of the main autobiographical texts in Bacon's works leads to a more firm chronology. Bacon's reform of studies is examined in order to present a clear picture of his list of the sciences. A comparison is made between Bacon's list and the list found in Robert Kilwardby's De ortu scientiarum. Further, the attitude of Bacon to the sciences is compared with that of John Pecham, O.F.M. and St. Bonaventure. The study of experimental science as a philosophical concept in Bacon illustrates his scientia experimentalis as a universal practical knowledge. This study consists of a review of modern interpretations since 1840, a reexamination of Bacon's texts together with new material on experimental science by Bacon. It is argued that Bacon was not wholly original in his experimental science. In fact, he appears to have depended on Peter of Maricourt
