INTRODUCTION

English translation pending.

CORE DEFINITION

An idiom meaning to wash away the stale and establish the new, breaking the old and setting up the new. Its core claim is that renewal needs clearance: before introducing something new you must first ask what has to be cleared away, otherwise the old accumulates beneath the new and the new can never settle.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Ask what to clear: before adding anything new, name what must go first. - Cut the dead weight: remove technical debt and stale structures deliberately. - Keep what still works: distinguish inheritable value from decay before deleting.

Anchor fast decisions

New structures cannot stand on uncleaned ground: old rules, habits, and debts compete for the same space and force the new into compromise. Clearing removes the competing constraints, so the replacement faces fewer antibodies and can actually take root.

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'.
