Hi Sevenstar,
Nice rebuttal. 
<<<Shuai chiao is a traditional CMA, and it takes this approach. Why would it differ for other styles?>>>
Shuai Chiao IMHO uses as different training protocol than other more common styles of Kung Fu. It is not that it is not traditional. It is just that it’s approach is different. As far as I understand it, it is one of the styles that doesn’t claim to have ties with Shaolin. There are basically 2 protocols or approaches to TCMA, one is short strike protocols (SSP), which is what Shuai Chiao is. The other is long fist protocols (LFP), which Shaolin styles over time adopted as the major training protocols. SSP doesn’t rely on long routines (forms) while LFP is heavily into forms. Shuai Chiao being a SSP style relies heavily on principles instead. The use of routines/forms in TCMA IMHO has its ritualist root in Kalaripayattu, which is also considered as an ancient temple art originated in southwestern India and brought to China by Bodhidharma. In a sense, practicing forms is like reciting sutra, it helps to promote and concentrate devotion (as a form of love), which is one of the the main ingredients for building a style.
For reasons unknown (I could speculate but not at this time), LFP became the more popular method and gained dominance in spreading MA through out China, then Japan and the rest of the world. I would say the popularity comes from LFP appeals to a broad demographic base. SSP is demanding and strenous, which is not necessary everyone’s cup of tea. Not that LFP isn’t hardcore, but it has a versatility that SSP doesn’t have. The truth is even scholars [re: bookworms, nerds] could appreciate forms.
and they are the ones who write about things so that glories could be retold and myths are spreaded far and wide in all eternalty. lol…
So there is a notable difference as we compare styles and approaches. It would not be accurate IMHO to generalize on TCMA by grouping them as one group of MA. We have to be aware of the diversity of TCMA.
<<<I can see your point there, however A style will not lose it’s identity. principles are common things, but they don’t change the essence of the style. look at the examples I showed. Also, the shearing principle is present in wing chun. will it look the exact same? heck no, because the principle is fitting within the style that is applying it. In addition to that, there are other obvious things, like footwork. My judo/sc and muay thai footwork will never look like my longfist footwork, and none of those will ever look like mantis footwork. Also, there will always be the individual style within the core style. muay thai is muay thai, however, I may prefer knees and the rear leg roundhouse, whereas my coach may prefer elbows and the front leg roundhouse.>>>
I think that is a need to discern system and style. If principles transcend systems and styles, why are we having so many systems and even more styles?
<<<how? With a structured curriculum, this should not be the case.>>>
The way I see it, structured curriculum is like a skeleton. You will need the muscularture to move the skeleton. Without the muscularture, the checks and blocks that students go through, the skeleton is just a pile of bones.
<<<I don’t see how it’s one dimensional. IMO, what’s more one dimensional is teaching set applications for techniques. It doesn’t encourage a lateral thought process. For example, you may have a sifu who teaches grabbing a strike and pulling your opponent into a strike of your own as the only application of “shoot the bow” The student may get in the habit of only using/seeing that application and never even begin to think that maybe that technique could be a fireman’s carry… When you understand a principle, what you can do with it is limitless.>>>
You have a point. but… In the example that you gave, I would say that it would not be the teacher’s fault. The teacher did his job by teaching what the “principle” outlined as permitted within the construct of the system and/or style. It’s a guideline. He definitely has the right to reserve furthering the guideline. This will bring us to the issue of the integrity of the system and of the teacher. I think that issue deserves another thread. It is nothing worse to me than a student needs me to spoon fed him/her. I don’t think you can make a good figther out of a spoon fed automaton. Personally, I don’t blame it on others for not seeing further. It is my solemn duty as a human being to expand and explore new grounds (within reason of course). If the teacher is a true guiding light the need for me to exlpore on my own is minimal. I will be more than happy to follow him til the very end. But I also needs to be responsible for my choices and not to blame it on others for my concious choices.
<<<I apologize, that was a miscommunication on my part. I meant to say that the student shouldn’t stress about it.>>>
No offence taken, my friend, no need for apologies.
