Really, it says right at the beginning, that the ideas can't be communicated by language, these are some pretty aloof descriptions. Not sure testing is how we should value ancient texts.
The Art of War is held up as some great text, but it has a lot of contradictions, and bad advice. (Not sure on this) Wish I had link, but apparently it was not used by generals in ancient times, it was more of a puff piece by a non-military writer.
