Josh Gold, the new editor of Aikido Journal, delivered a lecture/presentation at an ideas event in Los Angeles on November 10th in which he explained Aikido to the layperson. It is a wonderful analysis and expression of the spirit of Aikido and I encourage everyone to read it. You can access the article here.
