This has to be one of the most comprehensive articles on a model to understand the various dimensions of self defense I have ever read. Written by Erik Kondo, the author cites many of my preferred authors on several aspects of self defense, from Col. Jeff Cooper to Rory Miller, Massad Ayoob and "Animal" MacYoung.
This makes a very nice framework for examining several aspects of self defense, from the physical application of martial arts and systems to legal ramifications on use of force as well as societal dynamics involved in violence both social and asocial. I for one have always believed that while in the actual instant when violence is occurring there is very little time for analysis, all things leading to the moment when it happens should be deeply thought about a priori... Yet many people remain locked in their viewpoints due to lack of experience (or in some cases, too much experience), personal preferences or belief systems. Putting our own beliefs and prejudices under clinical examination is easier said than done, but what is a greater loss to you: the death of a part of your ego, or the possibility of an actual physical death due to a hard headed refusal to be critical about your own understanding of whatever knowledge you might think you possess?
Absorb what is useful, eliminate the unessential... to do this we must maintain an open, objective mind. Otherwise, how can we know what to keep and what to discard?
