This whole thing came out of my reading from a couple of different books lately. It's been building and I just had to say something. The interesting point that comes out of this is that I'm not entirely sure that I completely agree with what either of the books are saying, which comes back to your point Cicero.
While I don't completely agree with the authors, it is always good to have different points of view. Sometimes I might change my mind about issues I thought I had completely understood because something new or different comes to light. I don't view other points of view as a threat, so much as a learning experience.
I think, for instance, that while it seems that Will and I might disagree that he presents his point quite respectfully (and much love and appreciation to you for that, Will).
I like the ocean/waves metaphor.
