This novel, the story of two men of the early 20th century who stay on a remote island for 20 years and then find a Utopian Jewish state in Palestine, was the second of my "Herzl Trilogy" after The Jewish State. While I found this book a lot more fun than that boring screed, it too definitely has its issues.
For one, the book is mostly exposition given to Friedrich and Kingscourt, the main characters, by members of the New Society in Palestine. Granted, it's necessary in order to make both those two characters and us, the audience, understand how Palestine turned from an allegedly barren and swampy place to a Utopia within 20 years, but that doesn't make it any less dull to read. The worst part is when Joe Levy, who nearly single-handedly started the whole process, just gives pages and pages of exposition over a record player to the other main characters sitting in a living room. Ugh.
The book does have some interesting characters and events in it, but it really suffers from Herzl's colonial European mindset. He seemed to have little regard for the non-Jewish people already living in the land i.e. Palestinians, despite the nearly inconsequential inclusion of one character named Reschid Bey. That character really annoyed me as well, being the archetypal sycophant to his colonial overlords, stating that Zionism made everything better and showing a very Perennialist view of religion. Clearly, Herzl didn't have much experience with speaking to non-Europeans in his quest to create a Jewish state in Palestine.
Perhaps I'm being too hard on Herzl. After all, contrary to the actual founders of the State of Israel, he seemed to have no concept of Palestinians being expelled in mind for his Utopian vision of a Jewish state. Though he did have an extremely colonial, European mindset and almost completely ignore Sephardi and Mizrahi Jews - never mind the native Arabs - Dr. Herzl did have some good ideas that could, in theory, be beneficial to any society. We can't know what would've happened had he lived longer, but I don't think he'd be happy with what's happened especially since 1948.
There's really no reason for anyone to read this book unless, as I was, they're interested to see what Herzl's ideal Jewish state would look like. It's not great, it's not bad, it's just there - and it's somewhat irrelevant nowadays. Read it if you don't mind a lot of exposition, but otherwise just skip it.
