Whatever type Bruce Lee was, JKD isn't "synthesis", it's pragmatism. He taught people different things at different paces, and encouraged them not to even copy him. Bruce Lee didn't want to build anything. What he encouraged was formlessness, taking what you need from here or there, not getting dogmatic about any one approach, improvising. And not the kind of thing he thought one could learn by threshing about in their mind, but in doing, in sparring, in practice, in expression.
The highest technique is to have no technique. My technique is a result of your technique; my movement is a result of your movement.
Jeet Kune Do uses no way as way. The consciousness of self is the greatest hindrance to the proper execution of all physical action.
I have not invented a "new style," composite, modified or otherwise that is set within distinct form as apart from "this" method or "that" method. On the contrary, I hope to free my followers from clinging to styles, patterns, or molds. Remember that Jeet Kune Do is merely a name used, a mirror in which to see "ourselves". . . Jeet Kune Do is not an organized institution that one can be a member of. Either you understand or you don't, and that is that.
Knowledge in martial arts actually means self-knowledge. A martial artist has to take responsibility for himself and accept the consequences of his own doing. The understanding of JKD is through personal feeling from movement to movement in the mirror of the relationship and not through a process of isolation. To be is to be related. To isolate is death. To me, ultimately, martial arts means honestly expressing yourself. Now, it is very difficult to do. It has always been very easy for me to put on a show and be cocky, and be flooded with a cocky feeling and feel pretty cool and all that. I can make all kinds of phoney things. Blinded by it. Or I can show some really fancy movement. But to experience oneself honestly, not lying to oneself, and to express myself honestly, now that, my friend, is very hard to do.
