In this collection of two of Sédir's works, Austin Avison introduces Paul Sédir, situating him in the exciting period of societal and cultural changes during the pre-war years in Europe. Avison then offers a translation of Sédir's Dreams: Theories-Practice-Interpretation, a short discourse of how dreams function, their art, and a list of dream interpretations, and finally his translation of Magic Letters, which offers an insight into Sédir himself not only through his own prologue, but also in the collection of letters he curated for the collection. These two texts, along with Sédir's other contributions, marked a significant chapter in the development of French esotericism in the early 20th century.
