Tolkien was of course a deeply conservative man–and LOTR is full of conservative themes. But by one interpretation, the book also celebrates the technophobic Luddism that most conservatives associate with the environmental Left. See this essay, for example. I don’t agree with everything in it, but it makes some key points. Or read this one. It’s hard to deny that Tolkien was suspicious of capitalism. Granted, his suspicion was of a distinctly Catholic variety. But if he were around today I think he’d be a slow-growth, conservationist conservative.
I’ve written about Tolkien in several places, including here and here.
