' ... we are challenged to think ... these challenges will be the book's strength and delight even for those who have not bothered with ET and all that.' Christopher J. Corbally, S. J., , JHA 'As a source book this readable history is to be recommended, it is not just a science history but an intellectual and popular culture story.' Anders Hansson, Spaceflight 'As a source book this readable history is to be recommended, it is not just a science history but an intellectual and popular culture story.' Spaceflight 'The book ... contains useful historical references and many interesting comments, and will be appreciated by non-scientific devotees of the extraterrestrial life debate.' Irish Astronomical Journal 'Well researched and clearly written ... I recommend it to any who have more than just a passing interest in the history of the extraterrestrial life debate in the twentieth century.' Peter Stanley, Astronomy Now 'Steven J. Dicks masterpiece The Biological Universe... provides a wonderful account of the idea of life on Mars which abounded earlier this century and also discusses the role of the extraterrestrial in the literature ... This is a rare SETI book in that it can be easily digested by both the enthusiast and the professional alike. If I had to recommend a book for the serious SETI enthusiast to start with then The Biological Universe is it.' Modern Astronomer ' ... Dick, then, has written a large, ambitious and outstanding book.' Studies in History and Philosophy of Science
