Honor in the martial arts is something that goes back thousands of years. What the martial arts has taught us is that the most important person to honor is you. The martial arts in Korea dates back to 50 B.C. The first Honor Code had a philosophical background similar to the philosophy of today.
The Martial Arts Code of conduct of today is derived from the ethics and standards that have been taught throughout generations. The wording may vary from art to art or from school to school, but basically the conduct says the same message.
