The secular utopians basically said the exact same thing, they just took the Bible out of the equation. The religious and the secular groups recognized each other as fellow travellers. They exchanged newsletters and asked each other questions like, "What's a good soup pot to use if you're making dinner for 800 people?" They had these practical connections.

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?

don't think I should be in the business of making big pronouncements about where we are now, but I would say that dissatisfaction is as acute now as it was then.

They [Oneida people] didn't want to fix problems one at a time. If someone invited them to a feminist convention, their answer would have been, 'In the new world women will have total equality, so lets spend our energy creating that whole new world.' And to their credit, the women at Oneida probably had far greater practical equality than what any of the women gathered at Seneca Falls experienced in their lifetimes.

I was really interested in 20th century communalism and alternative communities, the boom of communes in the 60s and 70s. That led me back to the 19th century. I was shocked to find what I would describe as far more utopian ideas in the 19th century than in the 20th century. Not only were the ideas so extreme, but surprising people were adopting them.

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

The Enlightenment faith that things are getting a little bit better each decade becomes difficult to support. People recognized that there had just been a war that was worse than the war of 1812, and worse than the Revolution; things were clearly not getting better and better.
