Of course not. And neither have I said anything about Lao Tzu's type. I have only said that Taoism is and IP.
It's not the same thing, but the "temperaments" are very similar. And the book on your bookshelf has very little to say about Zen. It is much more interesting. I envy you if haven't read it yet. I wish I could read that book for the first time again ... that experience you can only have once in a lifetime. Don't miss it (and have patience the first 100 pages or so).
Yes, no doubt.
