Alberic of Paris
Alberic of Paris was a teacher of logic in Paris in the 1130s and 1140s. He was a major critic of Peter Abelard. No writings attributed to him are extant, but he is regularly cited by contemporary logicians. His followers were known as the Albricani.
The only source for Alberic's biography is John of Salisbury's Metalogicon. According to John, Alberic came to Paris around 1136 and attended Abelard's lectures on the Montagne Sainte-Geneviève. After Abelard left Paris, John attended lectures given by Alberic. Alberic left Paris for the University of Bologna before 1142. He returned to Paris only after 1146 (and before John wrote the Metalogicon in 1159). Upon his return, he rejected his former teaching and adopted a new one opposed to Abelard's.
