There’s plenty of rip-snorting adventure in Beam Piper’s SPACE VIKING: raiding, pillaging, space battles, political coups, gunfights in underground bunkers. Mainly, though, the novel serves as a platform for Piper’s political ideas. The planetary democracies in the book (like Marduk) he describes as effete, unstable, and easily toppled by demagogues (like Zaspar Makann) or external foes. Humanity tends on the whole toward “neobarbarism”; increasingly dependent on welfare-state handouts and the benefits of a technological society, they lose sight of those blessings’ costs, and either refuse to pay them or tear down their infrastructure in a fit of pique. The only society that makes sense to Piper is the feudal-libertarian one that his hero, Lucas Trask, establishes on Tanith. People get what they are willing to work or pay for, no more no less, with the minimal state services Piper believes they need (essentially a night-watchman state) provided by a warrior aristocracy. That the aristocracy also owns much of the means of economic production, making economic transactions intrinsically unfair, doesn’t bother Piper much. Kudos to him, anyway, for realizing the feudal tendencies within libertarianism more than four decades before political scientists did so.
Piper doesn’t seem to like women much in this novel, by the way. The only positive female characters are Trask’s former wife (generally only manifesting as a ghost) and a few simpering little girls. Perhaps HBP’s then-recent divorce made him more inclined to misogyny than usual, but IIRC he wrote LORD KALVAN OF OTHERWHEN at about the same time, and it had at least a few strong or sympathetic women in its cast of characters. Another note: as often occurs in mid-century space operas, the weapons that the Men of the Future employ in SPACE VIKING seem rather old-fashioned. Ground troops exchange machine-gun and rocket fire, space-going warships slug away at one another with nuclear bombs and “hellburners” (a sustained fusion-reaction bomb resembling the weapons in Wells’s WORLD SET FREE). Technological speculation apparently interested Piper less than political speculation, and, like many of his generation, he found it difficult to imagine a weapon more devastating than a nuclear bomb - except, perhaps, human complacency.
