London: Elek, nd [1958] dj. Hardcover first edition - A non-technical discussion by this noted astronomer (among other things he was the head of the Harvard College Observatory for over 30 years and discoverer of a large galaxy supercluster named after him) which concludes that it is time to write an obituary for anthropocentrism when it comes to the universe - not only is there very likely life elsewhere in the universe, but it may be smarter than we are. He concludes with the note that man's greatest enemy is himself - but also optimism that man will continue to learn about the universe, that rationalism will prevail, and that man can create beauty. Illustrated with photographs. 145 pp.
