Reasoning patterns that resemble fallacies but operate differently—arguments that look fallacious from outside but make sense within their context. Quasi-fallacies are the shape-shifters of logic: they wear the clothes of fallacy but serve legitimate functions. A circular argument in a formal debate is fallacious; the same circle in a therapeutic context might be healing. An ad hominem in a scientific paper is wrong; the same attack in a political context might be relevant. Quasi-fallacies remind us that fallaciousness is context-dependent, that the same form can serve different functions in different settings.
Quasi-fallacies Example: "He attacked the speaker's character in a political debate. Textbook ad hominem—but the speaker's character was directly relevant to the issue (trust on policy). Quasi-fallacy: it looked like a fallacy, functioned like a fallacy in some contexts, but here it was relevant. She couldn't dismiss it with a label; she had to address the relevance."
