circular logic
[SUR-kyuh-ler LAH-jik]
noun
lógica circular
1. A logical fallacy in which the conclusion of an argument is used as a premise, creating a self-reinforcing but ultimately unproven statement
The argument that 'God exists because the Bible says so, and the Bible is true because God wrote it' is an example of circular logic.
O argumento de que 'Deus existe porque a Bíblia diz assim, e a Bíblia é verdadeira porque Deus a escreveu' é um exemplo de lógica circular.
2. Reasoning that returns to its starting point without providing independent proof or establishing truth
Using circular logic to justify a policy is intellectually dishonest and unconvincing.
Usar lógica circular para justificar uma política é intelectualmente desonesto e não convincente.
Circular logic is frequently criticized in both American and Brazilian academic discourse. In Brazil, the term is particularly used in philosophical debates, journalism, and political discussions to expose weak argumentation. In the US, it's a common rhetorical critique in law, debate competitions, and media analysis. Both cultures value linear, evidence-based reasoning and view circular logic as a mark of poor argumentation or intellectual dishonesty.
