“As we know, there are known knowns. There are things we know we know. We also know there are known unknowns. That is to say we know there are some things we do not know. But there are also unknown unknowns, the ones we don’t know we don’t know.” So spoke Donald Rumsfeld, U.S. Secretary of Defense, back in 2002, regarding our knowledge of Saddam Hussein’s Iraq. He could have been talking about Judo, too.
“Man’s mind, once stretched by a new idea, never regains its original dimensions.” Oliver Wendell Holmes
The problem with stretching man’s mind, especially in a highly traditional sport like Judo, is that it’s fraught with opposition. Recently, I had the pleasure of conducting a USJA Coach Education Course for twenty-two coaches from Southern California. Several had shown up because they had heard that I was controversial! Much to their credit, they came to see and hear for themselves, rather than rely on the words of people who have never had an intelligent conversation with me.
John Locke was correct when he said, “New opinions are always suspected, and usually opposed without any other reason, but because they are not already common.” While I am considered controversial in Judo, my courses are based on the latest research, and I would be considered mainstream in other fields.
