Librarian Note: There is more than one author in the Goodreads database with this name.
Harry Harrison (born Henry Maxwell Dempsey) was an American science fiction author best known for his character the The Stainless Steel Rat and the novel Make Room! Make Room! (1966), the basis for the film Soylent Green (1973). He was also (with Brian W. Aldiss) co-president of the Birmingham Science Fiction Group.
As I recall, though, my biggest problem with many of the stories that our avoiding the scourge of war depended upon fundamental changes in human nature - i.e., we would have to become something other than human to escape it. Perversely, considering my usual pessimism regarding the species, I wanted to see stories where people created peaceful societies without having to genetically modify themselves or in some other way become nonhuman.
As with many multi-author collections, there's a range of quality here. I most enjoyed the short-short stories by Asimov ("Frustration") and Zahn ("The Peacemakers"), both on how to prevent wars from starting; William Tenn's first-contact story "The Liberation of Earth"; "The Lucky Strike," by Kim Stanley Robinson, on heroism; Joe Haldeman's semi-utopian "Beachhead"; and the very satisfying "The Long-Awaited Appearance of the Real Black Box," by Ratislav Durman. 3 1/2 stars.
This book has some of the most touching short stories about peace I have ever read - but it also has some of the least interesting as well. My personal favorites are "Iphigenia" (Nancy A. Collins), "We, the People" (Jack C. Halderman II), "The Peacemakers" (Timothy Zahn), and "Frustration" (Isaac Asimov). The rest of the short stories are decent enough, although not what I would call favorites. I highly recommend this book to anyone who likes Science Fiction, has an interest in politics, or enjoys thoughts of peace.
