When these lectures
were first translated into English and published in ANTHROPOSOPHY:
A Quarterly Review of Spiritual Science in 1929, lecture 16
“Earthquakes, Volcanoes, and the Will of Man” was not
published. Rene Querido translated this 16th lecture into English
from the French and kindly furnished the diagram following lecture 16
which shows the interior of the Earth. Rene Querido also wrote the
preface for this reprint edition.
