Miscellanea gathers together for Anglophone readers various articles by René Guénon and by 'Palingenius', his pseudonym during the time of La Gnose, a journal he founded in 1909. These articles have been divided into three categories: 'Metaphysics and Cosmology', 'Traditional Arts and Sciences', and 'Some Modern Errors'.
A sampling of chapters: 'Monotheism and Angelology'; 'Spirit and Intellect'; 'Silence and Solitude'; 'The Empiricism of the Ancients'; 'Gnosis and the Spiritist Schools'; 'The Origins of Mormonism', 'On the Production of Numbers', 'On Mathematical Notation'; 'Initiation and the Crafts'; and 'The Arts & their Traditional Conception'. In the latter two chapters the author explains why initiation became necessary in the measure that humanity receded from the 'primordial state', explaining the reasons for the degeneration of the arts and crafts due to the 'fall' or descending trajectory of the present cycle. He nonetheless points out the possibility of an initiation into the 'lesser mysteries' based upon the craft of building which still exists validly in the West.
