I am working on a post that relates to an ongoing discussion here and elsewhere when I once again looked at the yew tree in my front yeard (tiny front yard). I have been fascinated by this tree since I moved in 9 years ago and it is like an old and steady friend. One of the aspects of yews is that they are exceedingly geometricaly complex and, in spite of that, the branches rarely touch. One can think of a zillion human situations for which this could be a metaphor, including aspect of the brain. Fascinating.
