Bruce Lee’s philosophical influences

Bruce Lee was born on November 27, 1940, and died on July 20, 1973 (he would have celebrated his 82nd birthday last week). Since his passing, much has been said about his system, Jeet Kune Do, and its philosophical roots. They have all pointed to the same Taoist and Zen Buddhist sources that already lie behind other martial arts philosophies. But how Eastern is Lee’s system?
