I have a complicated relationship with the works of the British historian Tom Holland. While I’ve enjoyed all of his books that I’ve read, I’m always struck by two things. First is his tendency to indulge his own stylistic flourishes to an extraordinary degree and, second, to try to craft an all-inclusive argument that subsumes all things into itself. Though these might at first blush appear unrelated phenomena, they are in fact related, and each feeds into the other.

In Dominion, all of the things that I both enjoy and find infuriating about his work are front and center. Stylistically, this book is somewhat self-indulgent. It doesn’t seem as if Holland has any form of impulse control when it comes to his flights of fancy and his rather rakish and cheeky turns of phrase. To put it another way, he sometimes to be so in love with his own clever Now, don’t get me wrong. I like a bit of pizzazz in my prose, but when it’s repeated again and again and again, it starts to get a little cloying and, ultimately, distracting. Sometimes, I think that Holland should really make an effort to find an editor who can rein him in and keep him from indulging in some of his most exaggerated tendencies.

In Dominion, Tom Holland looks into the deep roots of Christianity and how, since its founding, its permutations and adaptations have shaped the modern Western world. Beginning in antiquity, he then moves into the modern world, showing how Christianity is, in essence, responsible for everything from socialism to science to secularism. And, in a rather counterintuitive move, he even suggests that such thoroughly un-Christian institutions such as ISIS are, even if they don’t realize it, Christian (he makes a similar argument about Hinduism and Judaism). Given that Holland has made no secret of his contempt for much of Islamic thought, I suppose I shouldn’t find this surprising, but nevertheless I did find it intellectually disingenuous (to put it mildly) and intellectually imperialist (to put it bluntly).

The real issue with Dominion, and with Holland’s work more generally, is his tendency to mistake his premise for his conclusion. Throughout this book, I kept wanting to hear the actual evidence to support the large claims that he makes. It’s not enough to merely assert that basically ever aspect that we have come to associate with modernity owes its roots in Christianity, and I’m not convinced that you could truly support such a huge claim with any degree of intellectual honesty. However, I’m also not entirely sure that I disagree with some of these assertions–I agree that secularism has no identity without the religious with which it is juxtaposed–but I don’t really think that Holland effectively or convincingly proves this point or, for that matter, many of the other ones. While I think he’s on surer ground on antiquity and the medieval periods, once gets to modernity things start to unravel rather quickly.

And, to be just a bit nit-picky, Holland also tends to make some slight errors that are frustrating because they’re so easily corrected. Early in the book, for example, he says that the Byzantines referred to themselves as such, when it’s pretty well-known that, for the entirety of their existence, they referred to themselves as Romans (even Europeans referred to them as Greeks, not Byzantines). Though these aren’t world-ending, when one is writing a book of popular history, and when one has a particularly large audience, accuracy becomes even more important.

That being said, I do think that Dominion makes some important points. Holland is absolutely right that Christianity was a truly world-changing development, and he’s also right that we in the West (or, to put it somewhat differently, the Global North) do owe much of our patterns of thought and our cultural sensibilities to Christianity. However, to use it as some sort of ur-myth that explains all of modernity…well, that still seems like a bit of a stretch.

Overall, I think that Dominion is vintage Tom Holland, and those with an interest in the broad history of Christianity and its influence on the ancient, medieval, and modern worlds will find it both enjoyable to read and informative. However, it’s also important that they approach it with a healthy dose of skepticism and, if possible, to seek out other sources to flesh out his narrative.
