Levi ben Gershon, or Gersonides, wrote 16 major works on religious, philosophic, mathematical, and medical topics. He spent most of his life in the major papal cultural centers of southern France and maintained extensive relations with Christian intellectuals. Gersonides was a supreme rationalist in the tradition of Maimonides, although they disagreed on a number of key points. Gersonides held that humans can attain certain positive knowledge of God and that humans possess a speculative intellect that permits the perception of truth and the attainment of immortality.
