You state that it is a martial artist's duty to take on an academic approach to historical investigation, which I also disagree with. As an instructor, I stress the moral and ethical standards and responsibilities that come with learning martial arts. I also intermingle history lessons from time to time, but not often in class. However, I would never suggest to any of my students that if they want to become a REAL martial artist they must devote ardent time to academic research on martial arts history. Would they benefit from it? Maybe.. . Is it necessary? No. This is not the perfect analogy, but here it is anyhow. I know how to shoot a gun. I spend time practicing to become proficient with its use, and I know the moral and ethical responsibilities of using it. Do I devote academic research on the history of firearms? No, I do not.
Your closing statement is downright silly. History teaches us that we are part of something larger than ourselves. It also teaches us lessons about conflict. The best instructors encourage students to dig deeper. However, most instructors, while they may be physically proficient and throw in an anecdotal story, skip the discussion of philosophy and history to the detriment of students. The real message of the martial arts/sports in modern America is about getting the next belt or trophy. So why bother to hang signs on the wall about "temperance," "justice," "self control," "honor," and "respect"? It is simply lip service if it is not truly made part of the curriculum.
