Philosophy[edit]

Since taekwondo is developed in several different kwans, there are several different expressions of taekwondo philosophy. For example, the tenets of the ITF are said to be summed up by the last two phrases in the ITF Student Oath: "I shall be a champion of freedom and justice" and "I shall build a more peaceful world."^{[citation needed]} Many forms of Tae Kwon Do, however, are based on what are called the "Five Tenets of Tae Kwon Do". These tenets are: Courtesy (Ye Ui), Integrity (Yom Chi), Perseverance (In Nae), Self Control (Guk Gi), and Indomitable Spirit (Baekjul Boolgool).^[30]
