To refute an argument is to show that it's not good by giving a convincing argument against it. Forms: 1. We can argue that some of the premises are dubious or even false (we can use [[Counterexample]]. 2. We can argue that the conclusion of the argument leads to absurd results ([[Reduction ad absurdum]]). 3. [[Refutation by Parallel Reasoning]]: We can show that the conclusion does not follow from the premises (or, in the case of an inductive argument that the premises do not provide strong enough support for the conclusion). 4. We can show that the argument begs the question (this is [[Reasoning in a Circle]]).
