The books are in the category “Philosophy and Science.” Many are also involved with consciousness. The description of the book, Consciousness and Marbles, along with the preview, give an idea of what the book is about. (The book is offered in 3 formats, paperback, and the two eBook formats, epub and pdf Adobe Acrobat. These should all be identical except that, for instance, the epub format requires no pagination or index. I recently constructed a new preview, which you can see with the paperback format or the pdf format.) The other two books are, so far, only in one format. I have a site, deeperuniverse.wordpress.com, having essays on sections in the books, providing area for comments, contacting me, and feedback.
