Hermann Beckh's lectures on language - published here in English for the first time - offer a unique and penetrating discussion of the origins and evolution of speech. Based on his professional knowledge of Tibetan, Sanskrit and Pali - and complete fluency in at least six other ancient languages, not to count nine modern languages - and accompanied by a heartfelt understanding of anthroposophy, the lectures comprise an unparalleled marriage of academic and meditative insights. Further, they give a valuable introduction to the author's later works on music, the stars and the Gospels of Mark and John. The Source of Speech features Beckh's complete series of articles on the subject that were developed during the early, 'seeding' period of his life and work. These include: 'Rudolf Steiner and the East', an unprecedented study of Steiner's relationship to Sanskrit and Buddhist spirituality; 'Let There be Light', Beckh's exploration of the six Hebrew words forming Genesis 1:3; articles devoted to the origins of language, Indian philosophies and the names of the Divine in sacred texts; and essays published in Das Goetheanum which examine speech sounds, especially those of Sanskrit and Classical Hebrew. Also included are contemporaneous reviews of Beckh's articles by Albert Steffen and Eugen Kolisko and a lecture on academia, materialism and the undisciplined enthusiasm for Indian spirituality, held at the University of Berlin. Nearly one hundred years on, Beckh's perspectives and themes remain as exciting, relevant and fresh as ever.
