On the Yin–Yang Principle
The yin–yang principle is the view that everything has two complementary aspects—such as yin and yang, positive and negative—and that this duality underlies the world at its root.
In Four Pillars (BaZi), yin–yang and the five elements are foundational. Western astrology likewise rests on frameworks such as the four elements—fire, earth, air, and water—and a yin–yang polarity. I view the yin–yang principle as a core truth of the greater cosmos—a universal principle underlying everything in this world.
In the yin–yang and five‑elements view, the cosmos begins from Wuji (the undifferentiated state), from which Taiji (the Supreme Ultimate) arises. Taiji comprises yin and yang, and from this foundation all phenomena express a two‑sided nature—a fundamental truth of the greater cosmos.
Yin and yang, plus and minus, male and female, white and black, light and shadow, X and Y chromosomes, good and evil, wealth and poverty, strengths and weaknesses, direct and retrograde motion.
Although I won’t go into detail here, one can even frame the persistence of war in terms of the world’s duality of good and evil. Because of this, resolving conflicts purely through dialogue is often difficult, and credible deterrence becomes critically important to prevent war.
There are many programming languages, but no program runs “as is.” Ultimately, all software is executed as machine code—bit sequences of 0 and 1. Since AI ultimately runs on software, the worlds it enables can be viewed as grounded, at the lowest level, in a yin–yang‑like binary of 0 and 1.
In this way, the yin–yang principle is both a deeply important cosmic truth and a universal foundation of everything in this world.
