Hey There,
I have to agree that they pretty much mean the same thing, but I have to assert that I didn't hear about "Kali"until I read Dan Inosanto's book. I'd lived in the Philippines and taken "Arnis" in our school for a part of YDT or Youth Development Training and then also at a camp for the Philippine Boy Scouts. I'd heard it referred to as "Arnis" more than anything else. My Uncle is from Cebu and he told me about Doce Pares Eskrima. But he used to "Doce Pares" as the term rather than "Eskrima". But not once did I hear about "Kali". On a trip back to Manila in 1997 I asked about "Kali" and people thought I was talking about the Hindu deity. Whenever I said "Arnis" they knew what I was talking about. I was for the most part talking with lay people and not FMA practitioners.
When I was in Cebu a few years later, the people referred to what they did most often by the Proper Name of the Style as opposed to the generic term of "Eskrima and we were all regarded as "Eskrimadors" in general. This is much like kung-fu practitioners will more likely refer to themselves as doing Wing Chun or Choy Lai Fut or Tai Chi as opposed to Kung Fu. The same goes with Karateka. They will say Kenpo or Shotokan more often than karate in general conversation. "Kali" was rarely mentioned and it seemed to be thought of more as the American word for "Eskrima". But in a multi lingual society like the Philippines, language is much more flexible than it is here in the monolingual US. So people don't get hung up on terminology so much as just being a means to getting the idea across that you want to impart.
Kalis Illustrisimo would of course be sword based as a "kalis" is a type of sword. You can see it on most "Weapons of the Moroland" plaques.
About the sword and stick things not relating to the development of each other, I have to disagree. The spanish kept detailed records and though they didn't really chronicle the FMA, they did chronicle technology. They introduced domestic steel to the Philippines. Before that time, often traditional wooden weapons were superior to the metal weapons made in the Philippines. Really durable metal weapons were brought by Arab, Chinese, and Indian traders. The record of Magellan's defeat is filled with details of fire hardened wood, and other wooden weapons. They were amazed by the weapon quality metal the Spanish had. Although taken from secondary sources it implies that if FMA existed then that it incorporated both wooden and metal weapons.
Before modern times, we can do nothing but conjecture. In modern times we can draw quite a nice developmental link especially in Cebu, which I believe is even where Kalis Illustrisimo finds its roots. Almost every system claims both blunt and edged weapon techniques. The Doce Pares system does. Balintawak does as does the Maranga. I think the interelation between the two is quite obvious.
I have not seen the posts that were made earlier on other forums to demonstrate the separation of development. Can you please post this information here? I'm always open to new information and my opinion is not set in stone. If there is empirical data to back up the claims, I would be willing to count it as true.
