Robert Silverberg:

"One essential component of great science fiction is strangeness. The story must take the reader someplace new and show him something he has never seen before...

Cordwainer Smith's 'Scanners Live in Vain,' one of the classic stories of science fiction, provides that essential degree of strangeness in two ways: by sheer originality of concept, and by a deceptive and eerie simplicity of narrative. It was the first published story of a remarkable man and a remarkable writer, and when it appeared in 1950 - in what was little more than an amateur magazine - it set off reverberations that opened the way for an extraordinary career.

For me it was a revelation. I read it over and over, astonished by its power. It had for me the fundamental science-fiction quality that I had been searching for ever since I discovered Wells' Time Machine and Lovecraft's Shadow Out of Time, and for which I continue to search to this day, some forty years later: it thrust me into a place that was utterly new to me, and imbued me with a residue of haunting images and impressions and feelings that I knew would never leave me."

John Clute:

"First, genuflect, genuflect: The Rediscovery of Man collects between one set of covers all the short fictions of the unmatchable, unthinkable Cordwainer Smith. All are magnificently weird, most are plain magnificent, and one or two are the nearest thing to perfection that you or I will ever chance upon in our little lives." (Interzone)

Gardner Dozois:

"If, when I was a young would-be writer, struggling for a glimpse of the Light from out of the stifling provincial darkness…, some supernatural agency had given me the chance to put on the saffron robe of an acolyte and sit at the feet of the writer of my choice, learning all that I could learn, I would have, without any hesitation, picked Cordwainer Smith as the Master at whose feet I would sit." (Modern Classics of Science Fiction, edited by Gardner Dozois, St. Martin's Press, New York, 1991.)

Scott Edelman:

"Sifting through tens of thousands of manuscripts in the slush pile over the years for Science Fiction Age, what I always hoped I would find is another Cordwainer Smith. Too many beginning writers are timid, fearful of stepping over the boundary separating the day after tomorrow from the vast, rich, unexplored universe beyond. Better than any writer we've yet seen, Smith represents the sense of awe and wonder that is the heart of science fiction."

Barry Malzberg:

"'Cordwainer Smith' is worth special mention . . . [Paul] Linebarger, a mysterious and complex figure . . . wrote of his mysterious and exotic far future, a network of civilizations through the galaxies administered by the diabolic and barely-glimpsed Instrumentality. Linebarger's style, a declamatory, deliberately overblown mythic narrative, has influenced hundreds of science fiction writers and has been outrightly appropriated by a good number. No one, in or out of science fiction, wrote like Linebarger; his work retains its mystery and power decades later, a mystery swathed within the enigma of that style and that never-glimpsed Instrumentality which must be the most barbarous Civil Service ever conceived." —SFWA Bulletin, Summer 2001
