René Guénon
Guénon’s The Great Triad was the last book to appear during his lifetime. Even for his regular readers, this book contained largely new material, as did his The Metaphysical Principles of the Infinitesimal Calculus, published the same year. The author here refers especially to the Chinese tradition, principally in its Taoist form (though touching on Confucianism as well), in which the ‘Great Triad’ is defined as Heaven-Man-Earth.
