Review of the hardback: From reviews of the first edition: 'In an age where philosophers and social scientists are trying to outdo one another in imitating physicists, it's refreshing and perhaps fitting that a physicist should remind them that there are important subjects that can't be approached in this way … Harrison has done a marvellous piece of historical research, and the book is filled with gems … He speaks in the language of science about mankind's age-old need to find meaning and order in a seemingly senseless Universe.' James Trefil, New York Times
