This blog contains an early, rough draft version of the book A Cosmist Manifesto.
I've left it up here for sake of amusement, and because some of the comments are interesting.
The final version has a lot of new chapters (maybe 1.5x as many as are in this blog) and incorporates a lot of editing.
You can buy a hard copy of the final version on amazon.com, click here
Or, you can download a PDF of the final version for free, click here
