Time magazine, using the collection as a springboard for a broader discussion of the sf genre, concluded that "The reader who reads science fiction dispassionately is likely to be struck by how closely the human imagination is tied to reality, even when it deliberately sets out to violate it. Stanley Weinbaum's loonies and slinkers have been seen before. The shapes may be different, but his dream-beasts come startlingly close to what the human race has been running across, for a good many years, in its childish nightmares."[1]
