Remember JKD is The Way of the Intercepting Fist. It was a style at first, when Bruce later used the quote "Use no way as way and no limitation as limitation." He had quit JKD he was doing the Art of Expressing the Human Body. Thats why he closed down his schools when he got his back hurt from (severed nerve or spinal cord damage) I don't remember which. He read something like 500 or 5000 books I don't remember which. This was in 1969 or 1970, thats when he made the discovery that the perfect style wasn't the answer and style was the problem. He has a 30 minute interview where he says "I do not teach karate anymore, because I do not believe in style." He says karate cause most Americans around that time mistook Martial Arts as Karate. I'm not saying Karate isn't martial arts i'm just saying that when they heard martial arts it was "What kind of karate do you do or something like that." I hope this enlightens you, it did me when I heard it all and pieced together the puzzle.
