Different styles of taekwondo adopt different philosophical underpinnings. Many of these underpinnings, however, refer back to the Five Commandments of the Hwarang as a historical referent. For example, Choi Hong Hi expressed his philosophical basis for taekwondo as the Five Tenets of Taekwondo:[37]
Courtesy
Integrity
Perseverance
Self-control
Indomitable spirit
These tenets are further articulated in a taekwondo oath, also authored by Choi:
I shall observe the principles of taekwondo, respect the instructor and seniors, never misuse taekwondo, be a champion of freedom and justice, build a more peaceful world.
Modern ITF organisations have continued to update and expand upon this philosophy.[38][39]
The World Taekwondo Federation (WTF) also refers to the commandments of the Hwarang in the articulation of its taekwondo philosophy.[40] Like the ITF philosophy, it centres on the development of a peaceful society as one of the overarching goals for the practice of taekwondo. The WT's stated philosophy is that this goal can be furthered by the adoption of the Hwarang spirit, by behaving rationally.
