Roger Bacon

On Signs (Mediaeval Sources in Translation) Roger Bacon Tra edition

Roger Bacon's Opus maius represents an attempt to create a whole new vision of what Christian education should be, one centered on service to the Church. One chapter of this work, "On Signs," is the most comprehensive and innovative treatise on semiotics in the thirteenth century. To understand the myriad ways in which things and words signify, Bacon says, is "a thing of marvelous usefulness and beauty."
