INTRODUCTION

English translation pending.

CORE DEFINITION

Named by Hans Albert after the Baron von Münchhausen, who supposedly pulled himself out of a swamp by his own bootstraps. The trilemma states that any attempt to justify a claim fully must either regress forever, circle back on itself, or halt at an unjustified premise. The point is not that justification is impossible but that every system has a chosen floor.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Axiom setting: Pick a small set of premises you will stop justifying and label them explicitly. - Foundation check: Ask where a chain of reasons bottoms out before extending it. - Bootstrap honesty: Admit which starting points are choices rather than conclusions.

Anchor fast decisions

Each reason demands a further reason, and the demand cannot be satisfied without either looping or stopping. Since an infinite chain is unusable and a circle proves nothing, the only workable option is a deliberate halt. Naming the halt converts an unexamined assumption into a declared premise, which is what makes the rest of the structure inspectable.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Take a belief you hold and ask what justifies it. 2. Repeat until you hit a loop, an endless regress, or a stop. 3. Name the premise where you stopped and mark it as a choice. 4. Check whether that premise is one you would defend on other grounds. 5. Rebuild upward from the declared floor.
