"As long as there is no general agreement on what does or does not constitute science fiction, there can be no agreement as to what 'pure' science fiction is, although the term is frequently used. But Charles Harness's THE PARADOX MEN must come close to anybody's idea of one kind of pure science fiction: the wild and imaginative kind which juggles amusedly with many scientific concepts."
- Brian W. Aldiss

"One thing I liked about Harness was the sense of sheer intelligence in his writing. His stuff is as imaginative as anything you will ever see, but also totally controlled -- a marvellous combination of extravagance and restraint."
Barrington Bayley, 1998.

"CLH is an original, stylish and imaginatively audacious writer whose relative neglect is difficult to understand."
- Brian Stableford
