Written in 1159 and addressed to Thomas Becket, John of Salisbury's The Metalogicon presents -- and defends -- a thorough study of the liberal arts of grammar, logic, and rhetoric. The very name "Metalogicon", a coinage by the author, brings together the Greek meta (on behalf of) and logicon (logic or logical studies). Thus, in naming his text, he also explained it. With this lucid treatise on education, John of Salisbury urges a thorough grounding in the arts of words (oral and written) and reasoning, as these topics are addressed in grammar and logic. Written more than nine hundred years ago, The Metalogicon still possesses an invigorating originality that invites readers to refresh themselves at the sources of Western learning.
