The Sleepwalkers

A History of Man's Changing Vision of the Universe




The 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. He also provides vivid and judicious pen-portraits of a string of great scientists and makes clear the role that political bias and unconscious prejudice played in their creativity.

Praise for The Sleepwalkers

The Sleepwalkers is a valuable and provocative book . . . a work with a noble aim

Sunday Times

The greatest part of this massive work is a close and valuable study of Copernicus, Tycho Brahe, Kepler, and Galileo . . . He writes tensely, with passion, as though personally involved, about events that took place more than 300 years ago
