taekwondo1-8, Exercise 2: Tenets and philosophies

Model answer:

Choi's Five Tenets: courtesy (yeui), integrity (yeomchi), perseverance (innae), self-control (geukgi), indomitable spirit (baekjeolbulgul).
Oath themes (also authored by Choi): observe the tenets; respect the instructor and seniors; never misuse taekwondo; be a champion of freedom and justice; build a more peaceful world.
Authorship: the article says Choi expressed the tenets and authored the oath; it gives no year; modern ITF organisations have updated and expanded the philosophy.

WT and Kukkiwon: WT refers to the Hwarang commandments; aims at a peaceful society; says this can be furthered by adopting the Hwarang spirit, behaving rationally ("education in accordance with the reason of heaven"), and recognising the philosophies in the taegeuk (yin and yang, the unity of opposites) and the sam taegeuk (change as interaction of heaven, earth and man). The Kukkiwon's position is likewise based on the Hwarang tradition. No named author or date appears for it.
