Ditto on Dawkins and Heinlein. Add in all of Marion Zimmer Bradley, Orson Scott Card, David Eddings, and Arthur C. Clarke. (Clear off four of my bookshelves...)
More by the Dalai Lama (what! you say -- non sci-fi??

) would be welcomed as well.
Just ordered a book at amazon _The Making of the Fittest_ because it wasn't on connect -- very irritated...
