I worry that I may have overstated the impact of Civil War on the utopians. By the time the Civil War comes, most of the communities were quite separated from the wider American society. Their rhetoric is still about transforming the world, but they're not having that much traffic with their neighbors.

The Oneida Perfectionists, along with some of the others, believed that feminism, and abolitionism, and other causes that they pursued in their own way without participating with other people outside of their communities, were all piecemeal reforms. That's what makes a utopian a utopian, this idea that they were going to create a whole new world from scratch.

That to me was one of the most exciting, and weird puzzles of this book: how are the most religious people and the least religious people of their time all drawn to very similar visions of utopia?

Some people think God is going to guide those humans. The Oneida community and the Shakers both believed that they had received revelations about how to build the New Jerusalem that the Bible says is coming

Utopians don't say, 'The world's corrupt, women make less money, people of color are oppressed at every turn.' You don't list the problems of the world; you describe a world in which those things aren't the case. The critique is implicit and as a result it's kind of a positive critique. You're not listing what's bad, but rather what would be good - you're oriented toward this positive vision.

They [Rappites] were moving from Southern Indiana to Pennsylvania, where they had originally settled when they came from Germany. They were looking for someone who wanted to buy a pre-built town, which wouldn't have been appropriate for any kind of normal settlement. That's when Robert Owen [Welsh industrialist and utopian socialist] buys the village and founds New Harmony.

There are Harvard grads, free thinkers, feminists, abolitionists, well-to-do people who want to go write poetry and live on a farm and cook and laugh and have a good time. As they themselves described it, it was an "inward facing" community. They were focusing on making a better existence for themselves, which I think is also the driving force of 20th century communalism in the US, the thought being that the world is corrupt, and we're going to build this little garden of innocence.
