INTRODUCTION

CORE DEFINITION

The line comes from the Dao De Jing: in pursuing the Way one subtracts daily, subtracting and subtracting again until one arrives at non-action. As a method it holds that understanding advances by removal rather than addition, because each element removed reveals whether the remainder still works. The core claim is that the essential is found by testing what can be deleted, not by deciding in advance what matters. The qualification is that removal must be iterative and verified: a single large cut removes the inessential and the load-bearing together, and simplification that breaks function is not simplicity but damage.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- List the parts: write every component of the object before deciding what matters. - Delete and test: remove one layer, see what breaks, and restore only what proves necessary. - Stop at the core: continue until the next deletion would damage the function itself.

Anchor fast decisions

Additions hide their own necessity, because a component that no longer serves a purpose looks the same as one that does. Removal is the only test: taking an element away and observing what fails reveals its actual role. Each pass also exposes the next layer of the real problem, which was previously obscured by the elements just removed, so progress compounds. The process terminates when further deletion causes damage, and that boundary defines the essential rather than guessing at it.

First Principles

In philosophy and science, a first principle (or first principles) refers to a basic proposition that cannot be deduced from any other proposition or assumption. The concept originates in philosophy from Aristotle's doctrine of the 'first cause', while in Kantian philosophy, its corresponding form is called a 'postulate'. In mathematics and formal logic, first principles manifest as 'axioms' or 'postulates', constituting the absolute starting point of logical deduction. In physics and other scientific fields, if the research process is entirely based on fundamental physical laws, without relying on empirical models or parameter fitting, it is referred to as 'from first principles' or 'ab initio'.
