Aristotelian Sophism

A form of sophistry that rigorously follows the rules of Aristotelian logic—valid syllogisms, no formal fallacies—while using false or misleading premises, or while ignoring crucial context. The argument is logically impeccable but unsound. It often takes the form of accusing opponents of committing logical fallacies (e.g., “that’s an ad hominem”) while being fallacious themselves (e.g., committing the fallacy fallacy). Common in strong-restricted debunking, anti-pseudoscience activism, and neo-atheism. The practitioner appears rational by wielding formal logic, but the reasoning is disconnected from reality or strategically omits counter-evidence. It is the art of being “formally correct” but substantively wrong.

Example: “He argued: ‘All pseudoscience is harmful; homeopathy is pseudoscience; therefore homeopathy is harmful.’ The syllogism was valid, but the major premise was false (some homeopathy may be harmless placebo). Aristotelian sophism: logically perfect, factually wrong.”
