Have you ever been with someone who, when they see a particular martial art technique, action, etc. immediately makes a comment like, “Oh, that’s no good” or “That won’t work,” but if you ask them to explain to you the reasons behind their comment, they’re unable to tell you, or all they can offer is some vague, nebulous answer. Whereas another individual can articulate exactly why they believe a technique or action to be ineffective and why they don’t think it will work. They can give you legitimate, clear reasons. The reason is that the second individual has cultivated what we refer to in Jeet Kune Do as the “educated” eye and “discerning” mind. What do these terms mean? The “educated” eye relates to the ability to look with eyes that can see what is functional from the perspective of structure and technique. The “discerning” mind relates to the capacity to filter out unrealistic concepts and theories, and ineffective techniques in one’s training. Both relate to having good judgment, understanding, and insight.
