There is an artistic motif known as "the tree of knowledge." I don't know how old it is, but there are also artists' trees known as "tree of life" and sometimes they're very similar.. . . .
Thinking about this concept though, in light of my children's never having gone to school, has brought lots of thoughts welling up in me about our culture's worship of books, both in what's good and understandable about that attitude, and also of the ways it has been and continues to be harmful and unreasonable in light of Howard Gardner's writings about multiple intelligences and of the "information age," which gives even non-reading children access to a huge world of input.
