 Moreover, some highly educated philosophers writing mainly in Latin worked outside the universities.  Ramon Llull  (1232–1315/16) wrote prolifically in Catalan as well as Latin and reportedly also in Arabic, devising his own logical system, unrelated to university logic, for thinking about God and his attributes and demonstrating the truth of Christianity. In the fifteenth century, non-university philosophers included the Cardinal and papal diplomat  Nicholas of Cusa  (1401–64), courtier and papal secretary  Lorenzo Valla  (1407–57),  Marsilio Ficino  (1433–99), protégé of the Medici in Florence, and the nobleman  Pico della Mirandola  (1463–94). They all developed their ideas in forms different from those common in the universities and held classical antiquity in high regard; Ficino was a noted Platonist  (§1.3.2),  Pico aimed to find wisdom in every available source, from the Kabbala to … university  theology.[21]
