Yea, it's my understanding that this meme is pretty old. "The Tao that can
be expressed is not the eternal Tao..." All Taoists probably host it, as
well as most of the Zen Buddhists. I'm fairly sure that just about any
mystical tradition will have expressed it at one time or another as well.
As to whether it's actually a meme... probably. A most unusual one, for
sure. Perhaps a good candidate for a memetic study?
