Provençal philosopher of the middle of the fourteenth century. He was a disciple of Samuel of Marseilles, and a relative of Shelemiah of Lunel, at whose request he composed a commentary on Averroes' middle commentary on the "Organon." In his treatise Cohen often corrects Averroes, and quotes Levi ben Gerson, whom he defends against the attacks of his (Cohen's) master, Samuel of Marseilles. A portion of this commentary, comprising the "Isagoge" and the "Categories," is still extant in manuscript (Christ Church, Oxford, No. 201).
