This is eventually the main reason why I mentioned Bateson's work in particular (besides the depth and orthogonality of his ideas).
I've read Watzlawick's work on interaction and pragmatics of communication before I've read Bateson's. I found Watzlawick's ideas easier to grasp (at least, I'm under that illusion), clearly presented with e.g. axioms. Then I read Bateson's work, and got this strange feeling of dwelling around the same underlying concepts, but without a clear understanding of his main argument.
I've read "Steps to an Ecology of Mind" quite a few times (I still re-read some chapters every once in a while) and always felt that a) I'm reading new material; and b) I'm not getting it all. Yet, I always get something new, and this is an extremely interesting insight on how my own perception changes over time.
Of course, this happens with other books and authors. Still, personally, I have a clear feeling that not to the same extent as it happens with Bateson's ideas. It's my own mirror, so to speak.
