Flight Into Yesterday

The Paradox Men is a science fiction novel by American writer Charles L. Harness, his first novel. Initially published as a novella, "Flight into Yesterday", in the May 1949 issue of Startling Stories, it was republished as The Paradox Men in 1953. The "science-fiction classic" is both "a tale dominated by space-opera extravagances" and "a severely articulate narrative analysis of the implications of Arnold J. Toynbee's A Study of History." Boucher and McComas described it as "fine swashbuckling adventure ... so infinitely intricate that you may never quite understand what it's about." P. Schuyler Miller described it as "action-entertainment, fast-paced enough that you don't stop to bother with inconsistencies or improbabilities."
