This is a community textbook project. The production
process was was funded by the more than 700 backers who pleged their contributions
through Kickstarter.com, an online crowd-sourcing fundraising platform. We raised
almost $17,000 to pay for the first edition's contributors, designers, editors, and publicists.
This enables the book to be published electronically for free, and in print for the lowest possible price.
Clear and Present Thinking is published under a
Creative Commons open culture license. This means anyone can use it, share it, and do
almost anything with it, as long as the creator's names remain attached to it.
The team and I would like to thank everyone for their generous support for their project,
and for helping make knowledge a little bit more free.
