Mencius said: "Without the compass, you cannot draw a circle. Without the square, you cannot draw a rectangle."
The phrase "不以规矩不成方圆" (without compass and square, no circle or square) became the Chinese idiom for the necessity of rules and standards. Freedom without structure produces chaos; creativity without discipline produces nothing lasting.
不以规矩，不能成方圆。
不以规矩，不能成方圆。

Core Wisdom
The circle is free — but it is drawn with a tool. The rectangle is regular — but it is measured. Even freedom needs a framework.
Mencius's metaphor is precise: the compass and square are not the circle and rectangle — they are the tools that make them possible. Rules are not the goal; they are the instruments that enable the goal. The artist needs technique before they can break the rules creatively.
This teaching resolves the tension between freedom and discipline: they are not opposites but complements. The compass constrains the hand — and the hand, constrained, draws perfection.
