Conscious Choice cover

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.


“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.


Available everywhere for $3.99 (before discount) at Amazon, Barnes & Noble, and all ebook vendors, or direct from the ebook publisher, ebookit. And if you buy it from ebookit you don't support the big tech companies and I get a bigger cut much sooner.

Beginning in June Staples will be the first major retailer to sell a 3D printer.

The price, $1299, is reasonable, but the printer will likely be capable of only making very small parts. Nonetheless, this is a start. The price will drop, and the capabilities will go up.

  • It also could mean a reduction in the price or increase in the availability of printing materials. Most people I know currently buy PLA and ABS on the Internet and have it shipped.

  • Now if someone comes up with an affordable 3D scanner, things will really take off.

  • Oh, they’re around.. most of them are Kinect based.. but it still takes a fair amount of skill to turn a point cloud into a 3d model which the printer can print.

  • My apologies. I should have said affordable and accessible. When the average person can have what amounts to a machine shop on their desk for a couple – three thousand dollars, and able to take credit cards (now available), there’s going to be a whole new industry. The potential is mind boggling.

  • We’re a long way away from that. 3D printers are neat, but they’re just another tool in the toolbox.

  • Absolutely. With a 3D printer you don’t first have to make a mold which makes it more accessible to more people. But it’s not the best tool for high production.

    It reminds me of that saying that if all you have is a hammer, everything looks like a nail.

  • There are many niche markets (model building, for example) where you don’t need high production to make a nice profit. The introduction of consumer – grade 3D printers and scanners is going to open a world of possibilities. I expect to see magazines devoted to hobbyist 3D printing this year (if they don’t already exist).

    I’m still seeing this as a niche market. The materials are high cost, you can’t make anything of much size, they take all night to print one thing, and most importantly, there is too steep a learning curve to make anything useful easily. I see this as a boon to people already in the business of making small prototypes for R&D, but other then that, its for geeks only. Even if the price drops significantly to lets say $300, how many people want to spend $300 to make $5 items? After all, its not like a machine shop at all. It only produces plastic.

  • Chris Kirkendall

    Can’t wait for the more advanced (& lower-cost) 3D printers to come out – I’ll snap one up & “print out” a Ferrari for myself – or would that be copyright infrigement ??
