Explanation
A fallacy in which the claim to be proven is already contained in the premises. In the atlas, the term is not treated in isolation: it reveals hidden circular reasoning. This makes it clear what distinctions the form enables and how it relates to related phenomena.
Example
This rule is correct because it is the correct rule.
Counterexample
A valid reduction to independently justified premises is not circular.
Distinction
A valid reduction to independently justified premises is not circular.
Effect on thought and perception
The concept draws attention to hidden circular reasoning. What previously appeared to be a unified process becomes perceptible as a structured relationship.
Resonance
Resonance arises when petitio principii is not merely named but experienced as a movement between form, expectation, and effect.
