The Sleepwalkers Reptiles The clock is tickingThe visionary history of the universe and human progress In this masterly synthesis, Arthur Koestler cuts through the sterile distinction between 'sciences' and 'humanities' to bring to life the whole history of cosmology from the Babylonians to Newton. He shows how the tragic split between science and religion arose and how, in particular, the modern world view replaced the medieval world view in the scientific revolution of the seventeenth century.
