Circular Reasoning

Also known as: Begging the question, Circular logic

A guide to circular reasoning, begging the question, and how LogicLens can help readers notice arguments that assume what they need to prove.

What it means

Circular reasoning happens when the argument's conclusion is already assumed inside the reasons offered for it.

Why it matters

Circular arguments can sound tidy because every part reinforces the same point, but they do not add independent support.

How LogicLens helps

Common signs
