Abstract
Roger Bacon was a very important logician in the thirteenth century and he had a profound influence on the development of logic, particularly in Oxford. He developed a theory of signs that had a lasting influence on the medieval and early modern philosophical tradition. The selection here presents his theory as developed in the beginning of On Signs.
