Welcome to the dawn of human cognition. This is not merely a philosophical inquiry, but a quest forspiritual awakeningthe pursuit. Laozi, in Chapter Two of the Dao De Jing, reveals with astonishing insight how humanity fractures reality through 'definition'.

1. The Symbiotic Relationship of Value Definitions

Laozi says:“When everyone in the world knows what beauty is, then ugliness arises; when everyone knows what goodness is, then badness appears.”This is an experiment on language and cognition. When a society uniformly defines a certain quality as 'beauty' (‘si’ meaning ‘then’), ugliness (evil) simultaneously emerges as its shadow. This symmetry implies that beauty and ugliness, goodness and badness, are not independent entities, but artificial boundaries created by human definition.

2. Delayed Construction and Power

This phenomenon is ubiquitous in human civilization. Take religion as an example,the concept of the Trinity (Father, Son, Spirit) established by the Roman Catholic Church emerged some 400 years after Jesus departed from the world. This reflects a universal principle: the original truth (Dao) is inherently whole and ineffable, while later generations construct 'orthodox' conceptual perspectives—through deliberate framing—to manage, disseminate, and establish order. Such construction defines what lies within the boundary, and what falls outside as heresy.

3. The Duality and Unity of Relative Concepts

The text mentions 'Being and non-being give rise to each other, difficulty and ease arise together, length and shortness define one another, height and depth leaning toward one another’. The character 'qing' means 'toward' or 'tendency.' When our mind leans toward one side, the overall balance is disrupted. Laozi reminds us that the sage (awakened being) understands thisduality and unity of relative concepts, thus transcending the constraints of definition, acting without effort, and teaching without words.
