This video does an excellent job explaining numerous variations of the classical boxing stance, from a boxing perspective (philosophy). Alot of what is said here transfers over to the philosophy of other striking arts, including weapon arts.
Remember that the differences are as important as the similarities though, so just because there are important parallels to be found between your art and boxing, it doesn’t mean that everything will transfer 100%. For instance, in the case of boxing, the cover-up (stonewall) defense makes sense for a number of reasons. Although movement may be similair for a knife fighter, the fact that a knife is in play makes the stonewall defense completely unusable (unless you’re ok with taking a slash/stab to the arm…)
Its also important to remember that in addition to considering the similarities and differences of technical realities, so too can the philosophical similarities and differences affect your ultimate decision to adopt or reject a given technique. For example, the philosophy (strategy, telos, etc) of a boxer is to view the fist as the totalizing tool for inflicting damage in a fight. An art that includes grappling, however, will likely view strikes as a tool for setting up grappling maneuvers, or simply as something to opportunistically take advantage of. Although all the technical skills of boxing may be “legal” in a particular grappling disciplines’ game, it doesn’t mean that their philosophy will lead them to adopt all those techniques in all the ways a boxer applies them. This isn’t an issue of technical form, but one of strategic/tactical/philosophical function.
Don’t blindly adopt techniques just because somebody gives a compelling argument or demonstration. Don’t blindly reject techniques just because “we don’t do it that way”. The fact is: a fist is just a fist, but when a boxer sees a fist he sees something different than what a wrestler sees, and a wrestler sees something different than what a kickboxer sees, and a kickboxer sees something different than what a CQB practitioner sees. For all these people, a fist is more than just a fist, according to the specificities innate within technical embodiment and philosophical application. Until one reaches a level of total martial mastery this is true, and then: a fist is simply a fist once more, for one is now free do use any technique or philosophy, for one understands all. This does not mean they will deploy their skill without consideration of technique or philosophy, but that their deep understanding frees them to know the most fitting time and place for everything they do.
