I'm not sure we should even call Erewhon a novel. If it is one it's a novel of ideas. Not like one of Aldous Huxley's though. Great ideas don't play out among characters or decide the plot. In Butler's Erewhon, characters are ciphers and narrative an afterthought—they exist just as an excuse to present the alternative society and allow the author to comment on it. Or rather, give the author an way to present his own ideas as though they are someone's else's.

There is a bit of narrative framework, a few chapters about how Butler's narrator stumbles onto the land of Erewhon (an anagram for "nowhere") somewhere near southeast Asia. (It sounds geographically like New Zealand where Butler once resided.) And there's an adventurous escape by balloon near the end.

But Erewhon is really more a work of philosophical, religious and scientific speculation. The novel is often called dystopian—since it purports to describe a bad imaginary society—but really Butler is more concerned with showing us our own world. Each aspect of the ridiculous nature of the state of Erewhon has its counterpart in our own society, or at least in Western society of Butler's time.

Sometimes the comparisons point up opposites between our world and Erewhon, as in the Erewhonian condemnation of sickness as immoral and criminal, while they are quite understanding of what we would consider criminal activity such as theft. Sometimes the differences are near-parallels, as in the mystical belief Erewhonians have in a before-life of the unborn, while most citizens of our world hold out hope for an afterlife. In both cases, the intent is to point up how illogical our own attitudes are. Butler makes no attempt to explain how such a society as Erewhon's could actually function with such bizarre laws and economics.

Sometimes he just seizes the opportunity to put his own theories into other people's mouths. Religion is one of the two great topics that absorb him. Butler is still a Christian here but in defending his beliefs to Erewhonians he reveals to us they are based on nothing better than the Erewhonians' strange creeds. The all-out criticism of The Way of All Flesh is still a few years away but we see him expressing doubts in Erewhon. Religious skepticism plays a role throughout the story, being evident even behind the long exposures of the Erewhonian banking and educational systems.

Butler's other prime target is Darwinian evolution. During this period of great intellectual upheaval during the later nineteenth century, Butler sided with the evolutionists but came up with his own variation on Darwin's theory which allowed the inheritance of habits. This would become full-blown in Butler's later non-fictional works, which are probably better forgotten, but here he just hints at it. He recycles an earlier piece he had written about the rise of intelligent machines in the future, attributing it to an Erewhonian philosopher, and in a similar fashion goes on about consciousness in animals and plants. Interesting stuff—some of it outdated but some of it still profound.

Okay, the truth is that much of Erewhon is very dull reading. If you want a good story, forget it. You have to be interested in the ideas he raises to get much out of this so-called novel.

Yet Erewhon has lasted into its second century while other utopian/dystopian fantasies have come and gone. Perhaps the ideas are of interest beyond the religious and scientific concerns of the 1870s.
