The purpose of the present study is to find out whether Baduk could be included in physical education or a sport or not. To compare Baduk with a sport or physical education in a diachronic aspect, it is approached on three views, that is, normative, realistic and future oriented concepts. The following findings are obtained. First of all, a sport or physical education are involved in physical activities. In contrast, Baduk requires intellectual activities. According to this concept, it is examined closely that these couldn’t be included in same category. Second, the argument that Baduk could be a sport or physical education is based on needs for political and selfish actions. A sport or physical education and Baduk might be lose their own identity without considering academic judgment or verification of philosophical theory throughly. Lastly, mind sports (i.e. Baduk) and e-sports in cyber space should have independent fields as themselves. It’s necessary to have their own categories between a sport or physical education and others.
