Yin and Yang


The principle of Yin and Yang from Chinese philosophy is that all things exist as inseparable and contradictory opposites. Examples of Yin-Yang opposite forces are female-male, dark-light, and old-young. The pairs of equal opposites both attract and complement each other. The Yin and Yang principle dates from the 3rd century BCE or even earlier.
