The Traditionalist or Perennialist school, founded on the work of René Guénon and continued by Ananda Coomaraswamy, Frithjof Schuon and others, holds that the orthodox religions are formal expressions of one primordial metaphysical truth. Schuon’s The Transcendent Unity of Religions (1948) gave the school its watchword. It is sharply critical of modernity.
