  Harry A. Wolfson once described medieval philosophy as a philosophy “which placed itself at the service of Scriptures” (Philo, II, p. 439). From a formal aspect, a new genre was created: “From now on, a new form of exposition appears in philosophic literature, the homily on some scriptural text or the running commentary upon some scriptural books” (p. 444). Joseph ibn Kaspi is a perfect illustration of this characterization of the medieval philosopher. He wrote some thirty works dedicated to explaining the Bible, in which philosophy served him both as a method and as a compendium of philosophical conclusions which, to his mind, the biblical author had wanted to convey to the reader. Some of Kaspi’s works were devoted to logic and linguistics as methods suitable for biblical exegesis; others were commentaries on books of the Bible or supercommentaries, and he also wrote on theological subjects. Of this vast oeuvre, only some has been published; much remains in manuscript, and some works have apparently been lost.
