INTRODUCTION

English translation pending.

CORE DEFINITION

First principles inquiry asks after the ultimate grounds of a thing, refusing assumptions that have not been examined and rebuilding understanding from the base. The core proposition is that received practice is a hypothesis rather than a foundation, so reasoning should start from what can be verified or must be granted. The key qualification is that the search is for the premise explaining the phenomenon, not for one final answer, and each step up the chain must be checked for self-consistency.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Assumption strip: write down everything you are taking for granted, then mark which items are actually verified. - Why ladder: keep asking why until you reach a premise you cannot push any further. - Rebuild test: reconstruct the solution from those premises and see what constraints disappear.

Anchor fast decisions

Convention accumulates layers of inherited reasoning, and each layer hides its own assumptions. Asking why until the chain bottoms out exposes which steps are load-bearing and which are merely habitual. Rebuilding from verified premises then removes constraints that were never necessary, which is why the method so often produces solutions that look obvious only after the fact.
