"Engdahl has marshalled an impressive and fascinating selection of primary sources--including a roster of believers that includes Newton, Ben Franklin, Walt Whitman, and rocket pioneer Robert Goddard; and . . . reminded us that our ancestors entertained a view of the universe that was larger and more imaginative than the history books lead us to believe. Challenging and original." --Kirkus Reviews, 17 October 1974

"By piecing together fragments of the past, The Planet-Girded Suns has placed the belief in extraterrestrial life into sharp perspective."
