Reception
John ONeill, covering the 1970 reprint edition retrospectively on blackgate.com, writes "[n]ot that everything was better in the good ‘ole days, ... [b]ut you could get terrific original anthologies in spinner racks at the supermarket for under a buck ... like Groff Conklin's Minds Unleashed [with] great science fiction stories about 'the potential of human imagination and the range of strength of human intelligence' by Arthur C. Clarke, Theodore Sturgeon, Murray Leinster, Robert A. Heinlein, Poul Anderson, Eric Frank Russell, Isaac Asimov, William Tenn, and many others."
