Two of the most well-known martial artists are Bruce Lee and Miyamoto Musashi. They were two martial artists from different time periods, yet they espoused the same pragmatic philosophy of fighting that defied their contemporaries' views. Bruce Lee was a film star and martial artist, and Musashi was a samurai.
Bruce Lee founded Jeet Kune Do, or the Way of the Intercepting Fist. His philosophy was that no form or obvious structure should exist in fighting. Therefore, he taught basic techniques in martial arts, focusing on sparring and extreme conditioning. Lee was considered to be one of the most physically fit people of the 20th century, capable of incredible speed.
Miyamoto Musashi, who lived in the 1600s, is most famous for his treatise on Japanese swordsmanship, "The Book of Five Rings," in which he describes his philosophy of using everything at a fighter's disposal to fight and devoting fully to bushido. He is also known for creating the sword style of Niten Ichi-ryu, which advocated the use of both the katana and wakizashi — or at least the ability to use a sword one-handed. Musashi frequently used psychological warfare and the environment to ensure victory. For example, he deliberately showed up late to his famous duel with Sasaki Kojiro, taking advantage of the samurai's anger and catching him off-guard to kill him.
