Perennial philosophy
Perennial philosophy (Latin: philosophia perennis; sometimes sophia perennis, with "sophia" meaning "wisdom" and "perennial" meaning "eternal", literally "lasting through the years"), also known as perennialism and perennial wisdom, views the world's (religious) traditions as sharing a common truth or origin.
Perennial philosophy as a term has its roots in Renaissance interest in neo-Platonism and its idea of the One, from which all existence emanates. The term perennial philosophy was first used by the Italian Agostino Steuco (1497/1498–1548) who in 1540 published De perenni philosophia, which argued that philopical/religous views of classical antiquity were in essential harmony with Christian views. A related term is "prisca theologia", first used by the Italian Marsilio Ficino (1433 – 1499). Giovanni Pico della Mirandola (1463–94), a student of Ficino, went further than his teacher by suggesting that truth could be found in many, rather than just two, traditions. However, their views lost influence after the Renaissance.
Wikipedia dubiously lists numerous later views, organizations, and individuals as perennial philosophy. That many of these themselves used the term(s) is dubious.
The term(s), sophia perennis especially, may now be particularly associated with the Traditionalist School.
