Two thoughts strike me as I drive in to work today.
The first is of a picture I saw recently of Bill Nye, with the caption, “Everyone you will ever meet knows something you don’t“. Never assume that a person has nothing to contribute to your understanding. The central message of the JKD philosophy, “Absorb what is useful, throw away what is useless, and add specifically what is your own“, requires enough understanding to recognize what is useful or useless. A principle must be understood before it can be evaluated. One must learn before one can assess. The quality I admire most about Guru Dan Inosanto is his ability to look at each art with a sense of openness. Everyone you meet knows something you don’t.
The second thought is a response to the first. Humility and integrity are the only defense against self-deception. Never borrow someone else’s truth. Test everything, and forgive yourself for being less knowledgeable or less skillful than you’d like to be.
