This is a weird book, you guys. Weird even by the standards of sixties science fiction, weird even in the career of E.E. "Doc" Smith. Which is not to say that it's a very good book, by either of those standards; but it pushes against the mores of time, place and genre in a way that's interesting if you're a weirdo like me, who views society through the lens of what kind of people get to be protagonists.
Having read a lot of Smith's pre-World War II work, I was surprised at how different The Galaxy Primes felt - specifically, in the realm of character, it felt less like the other Smith work I've read, and more like the characterization of Smith's friend and compatriot Robert Heinlein. This is not a great thing, though, because our Prime couple shows the traits of Heinlein's most annoying protagonists - highly competent and highly defensive, puffing themselves up at the drop of a hat and making big speeches about how the world really works at anyone the narrative designates as lesser. And naturally, when they apply this behavior to each other, no matter how nasty and petty it gets (and no matter how painful in terms of sexism), it means they're Meant For Each Other.
At least, that's the status quo at the beginning of the book, when said couple and their not-quite-as-powerful-but-equally-competent-and-way-nicer friends are exploring the outer universe. (Incidentally, the female member of that couple is a person of color who gets to be beautiful, powerful, kind and skilled. She does, however, get saddled with the nickname "Brownie", because we can't have nice things.) Halfway thru, though, after a thinly veiled and very angry satire of the Cold War, things shift. It feels like Smith, in the process of getting inside his characters' heads, realized - wow, being someone who's constantly a superior jerk to everyone around them would actually really suck!?
At that point, we move back to Earth's galaxy, and our main couple travels around, discovering that nearly every inhabited planet has a pair of Primes, and almost every such pair are assholes who need to be taken down a peg before they're ready to be part of galactic civilization. It feels like a direct attack on a particular idea of "toughness" and "strength", an acknowledgement - incredibly rare in this era, especially among non-hippies - that being the loudest and the pushiest and the most confrontational doesn't actually mean that you're the best, or even good at what you do. This is especially true when the most pressing problem is that our main pair realizes that they, too, need to be taken down a peg - but how?
Like I said, this is a weird book. It seems to be reacting intuitively against several things - the framework of masculinity in mid-20th-century America, the mindset that being in the military imposes on you on what a Good Leader is and how they act. Yet at the same time, the not-so-intuitive level of the book is pushing the same old shit - a narrowly defined gender binary, the idea that military rank and discipline is preferable to debate and representative government. It's very of its time - the copy I got from a secondhand bookstore had cigarette ads in it - but also very much in reaction against and dialogue with that time. It's a frustrating read, but it has definite historical value, and it's reaching for the stars.
