The Blind Spot is a science fiction novel by American writers Austin Hall and Homer Eon Flint.

It was first published in book form in 1951 by Prime Press in an edition of 74,200 copies, though fewer than 800 were actually bound, and the remainder are assumed lost.

In In Search of Wonder, Damon Knight is critical of the novel's coherence, scientific accuracy and style:[1] The Blind Spot, by Austin Hall and Homer Eon Flint, is an acknowledged classic of fantasy, first published in 1921; much praised since then, several times reprinted, venerated by connoisseurs - all despite the fact that the book has no recognizable vestige of merit.Groff Conklin, however, more generously termed The Blind Spot an "honored classic" despite being "overwritten [and] leaning a little heavily on the pseudo-metaphysical.

"[2] Forrest J Ackerman described it in Astounding as a "luxuriantly glorious Merrittesque [fantasy] of dimensional interstices" and "a highly philosophical work.

He concluded that while its opening section "evoke[s] a considerable sense of wonder," the novel "soon degenerates into a routine adventure story with loose ends.
