We cannot just ask a book, hey book, tell me about the temple of Luxor. No. A reader is consuming the fruits of labor by the writer, and is tasting the work at some level, savoring it in the case of Schwaller. It becomes a moveable feast...
"An appetite is developed between reader and writer to continue the story, to take the work further and evolve the seed into a tree of knowledge. And other works by other writers become the branches bearing new fruit. There is an ancestory of consciousness woven into the substance of a human writer. Readers, are mind readers. We are reading the minds of writers. We are living in the seen and unseen worlds"

We observe and absorb the world that has been formed by those before us, and work to evolve a new world formed by us for our future generations.
