Hopefully you've had a chance to read and view the material on the 52 Blocks. It occurred to me today that 52 is an interesting parallel to Ninjutsu. Not necessary in the styles themselves, but the pedigrees.
The Takamatsuden "Ninjutsu" schools have had a hard time finding accpetance for many different reasons. First is the history and documentation of the lineages. As a "secret" art used by warriors considered less than the noble, honorable ideal, the ability to trace real history is hard. Documentation of the schools was nearly non-existent. Historians and Martial Arts Masters questioned the legitimacy of such an art, and even questioned the morals and motivations of anyone who wanted to learn an "assassin's art."
52 is also an underground style, closely associated in the popular imagination with thugs and prisons. It has no documentation associated with it -- so how are we to trace any development? We rely upon oral history accounts and vague connections to historical figures or developments, such as the more evasive style of African American boxers as they rose to prominence.
This is, of course, a gross oversimplification. But it makes you think about certain issues. If 52 Blocks is now emerging from the shadows to become a legitimately recognized martial art, what kind of frictions will it encounter on this journey? Will it find more ready acceptance?
I'm eager to hear more about the 52 Blocks. I think this is a fascinating American story and our country's contribution to the martial arts.
