Boucher and McComas, describing Kuttner as "one of s.f.'s most literate and intelligent storytellers", found the collection to be "just about as good as the modern magazine science-fantasy story can get".^[3] P. Schuyler Miller similarly reported that Ahead of Time was "as good as any of the short-story collections now being published".^[4] New Worlds reviewer Leslie Flood described Ahead of Time as "excellent".^[5]
