Bacon, Roger (c.1214–92/4)

Associated with both the University of Paris and Oxford University, Roger Bacon was one of the first in the Latin West to lecture and comment on Aristotle’s writings on subjects other than logic. After he came to know Robert Grosseteste’s work in natural philosophy, he became the advocate of a curricular reform that emphasized scientific experiment and the study of languages. His views were often unpopular, and he constantly belittled all who disagreed with him.

Bacon’s work in logic and semantic theory had some influence during his lifetime and immediately after his death. His work in science, however, had little impact. His renown in the history of science is due in part to his being viewed as a precursor of the Oxford Calculators, who in turn anticipated certain important developments in seventeenth-century science.
