Of course, I have to agree with Hock here.
When I first met Hock I was somewhat of a purist. Although I jumped around from system to system, I always devoted myself to the particlaur system I was involved with at the time. Example, when I trained in kenpo I would only practice kenpo as it was passed to me by my instructors in the way it had been taught to me. When I met Hock, my eyes were opened to the ways of innovation and more importantly they were opened to the concept of "reality-based" training. I came to realize that the majority of martial arts are about doctrine, unconscious brain-washing, and the devotion to history for the sake of history.
No, we are not likley to develop a tool or tactic that has not been discovered, taught , or used somewhere else. However, by striving to be innovators we can develop our personal skills way beyond that which we might aquire through the purist mind-set alone. We might develop a way of presenting the material, that has not been thought of before, or has been overlooked before now. This can be seen over and over again in modern times when someone draws attention to certain tools or techniques that have been around for quite a while but were overlooked before. These tools & techniques are given catchy names and are presented in ways that grab people's attention. Of course, people who have never seen such tools or techniques before think that these are new developments when in fact they are only modern innovations of old material.
As the old saying goes, "there is nothing new under the sun". However, there are new ways to present the same old material or to improve the learning and retention ability of the students. There are new ways to grab the student's interest or to spark their creativity. All of which, leads to better students & better instructors. It creates future innovators rather than mindless drones or robots that just follow commands and then pass those same commands on to their future students.
