I've read the "Top Secret" and "Not For Distribution" Wedge Document, which years ago confirmed DI's strategy when it was leaked. The main author of the book mentioned by SirLinksalot confirmed its authenticity.
Any of the books they publish afterwards are towards this end. If they appear scientific-sounding, that means their strategy is working. The Privileged Planet was written by two people from the very same Discovery Institute.
Okay for you, all knowing.
