It all depends what you mean by "today's knowledge". When Wolfgang uses the phrase, it means one thing. When I use it, it means another. When Two Bears uses it, it might mean another.

There's a lot of knowledge out there, but people aren't all agreed on their interpretation of it.

They used to say "George has carnal knowledge of Mary", and it meant that he had had sex with Mary, therefore was aware of her in a physically intimate sense. It is my opinion that Wolfgang does not have carnal knowledge of Chi. Some people, however, do. (Chi being a form of vital energy.) Wolfgang HAS Chi, like everyone, but he is probably unaware of how to move it...or that it can be moved in order to heal another person, animal, or plant...or to heal oneself. That doesn't fit into his definition of "today's knowledge". It does fit into mine. It's totally obvious at this point.
