This book, published in 1978, was the subject of the first Spanish translation in 1982 and was distributed in traditionalist circles of the time in no more than 150 copies. Now we again, but via the Internet, invite the reader to evaluate the quality and clarity of Daniel Colon's presentation. In this text, which is based on the Evolian and Guenonian points of view, the author shows not only knowledge of the world of Tradition, but also reliable objectivity. Some parts of the text overemphasize the anti-New Right debate; it is necessary to consider these lines in the context of the intellectual controversy that France was experiencing at that time.
