When the manual stops and we go on in our speculation beyond the documented techniques, is that being true to the art. It is a double quandry.
1. If you extrapolate, you may be wrong
2. If you don't you are limited.
Totally agree with everything that you have said here, especially the last part.
What I have found, and I suspect that Phillippe may have the same mileage, is that you should continually go over and review your source based on the new things that you have found out through your first study of your source.
For instance I work mainly with Fiore nowadays, although I do keep a hand in with other Historic sources. When I first worked through his system I obtained a good overview of the techniques, I then decided to concentrate my studies upon the unarmed section, building the section up based on what I had found out through studying the other techniques, taking what was common and applying them in this arena. This was a fairly continual process which took almost 2 years to be able to draw a line under (sometimes a dotted line). This was something that I was not expecting.
I then moved on to an in depth study of the dagger section, which overlapped the work I was doing with unarmed, and even though I had taken some of the lessons from the dagger and had already applied them to the unarmed, I was almost shocked to find that there were still elements from the dagger that I had to take back to the unarmed, which further opened up the dagger, which in turn further opened up the unarmed. This in turn has led to a greater understanding of the later sections.
This is fairly mind blowing stuff for me, as rather than supporting people's opinion that there is only so much that the Master can convey in the text, it tended to show that the system can be found, by following exactly what the master says, looking at a technique while adherring to his instructions, and then finding the underlaying lessons that are not transferred through words but rather through the actions of following the technique through..... does that make sense?
The story does not stop there. At some point I felt that I had enough system to take out and show and use with people from different systems. The system held up in a variety of places. Where it did not hold up was down to me not follow the Master's instructions or lessons, when it was successful it was because I had followed the system.
There was much that I found to be common, I often had people say to me that they had similar things going on in their system, but what that tended to boil down to was that they had a similar technique, but when questioned the decision making process, the tactical consideration and even the manner of physically moving to get to that technique could be different - though this may have boiled down to individual style rather than the style of the system that was being practised. This has been largely true of all the aspects that I have been able to test in this manner, eg unarmed, dagger, sword, cudgel, bastoncello etc
So, what I have found, rather than reaching a dead end, I have found that I have been using other arts to confirm or refute theories, parts of system and technique rather than using other arts to fill in the gaps.
This is not always possinle with some texts as there is just not enough data to do this with, but with something like Fiore you can really build up parts of his system that at first site appear to be extremely minor for example the abrazare or the spada a uno mano.
Hope this makes sense for people, and I hasten to add, that other people have different methods of working that are probably just as successful as the methodolgy that I have found myself applying - what is important is that we always keep an open mind and be brave enough to openly share what we have found, even if that does bring about riddicule or derision. Who knows, perhaps everyone else has it wrong <img src="/forum/images/icons/smile.gif" alt="" />.
Enough waffle.
