CORE DEFINITION

Any proof ultimately faces one of three predicaments: 1. Infinite regress (A is proven by B, B by C, ...); 2. Circular reasoning (A is proven by B, B by A); 3. Dogmatism (I say so, no proof needed).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Skeptical undertone. Acknowledge that the foundation of human knowledge is suspended (usually based on axiomatic dogmatism). Do not pursue absolute truth, only 'the best explanation for now'.

anchor

Anchor fast decisions

The ultimate basis of any argument can only fall into one of three: infinite regress (the chain of proof has no bottom), circular reasoning (mutual proof), or dogmatism (stopping at an unproven premise/axiom). The foundation of knowledge is 'controlled dogmatism' rather than absolute truth.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

When pursuing an argument, identify which predicament you fall into. Explicitly declare basic premises as 'axioms/assumptions' rather than pretending they are proven. Accept 'the best explanation for now' rather than absolute certainty.
