Law of Absolute and Relative Logical Fallacies

The principle that fallacies operate in two modes: absolute fallacies (errors that are fallacious in all logical systems, by any reasonable standard) and relative fallacies (errors that are fallacious in some systems but may be acceptable in others). The law acknowledges that some errors are universally wrong—affirming the consequent is a mistake in any logic that cares about validity. Other errors are system-dependent—what counts as a fallacy in formal logic may be perfectly acceptable in rhetorical argument. The law of absolute and relative fallacies reconciles these by recognizing that fallaciousness has both universal and context-dependent dimensions.

Law of Absolute and Relative Logical Fallacies Example: "He accused her of ad hominem, claiming it was an absolute fallacy. She pointed out that in political debate, attacking character is sometimes relevant and not always fallacious. The law of absolute and relative fallacies said: in formal logic, absolutely fallacious; in political rhetoric, context-dependent. Both were right, which is why fallacies are complicated."

Law of the Absolute and Relative Fallacies

The principle that fallacies operate in two modes: absolute fallacies (errors that are fallacious in all contexts, by any reasonable standard) and relative fallacies (errors that are fallacious in some contexts but may be acceptable or even valid in others). The law acknowledges that some fallacies are universally wrong—affirming the consequent, denying the antecedent, non sequiturs that genuinely don't follow. Other fallacies are context-dependent—appeals to emotion that are appropriate in some settings, ad hominem that is relevant, slippery slopes that sometimes happen. The law of absolute and relative fallacies reconciles the need for logical standards with the reality of contextual reasoning.

Law of the Absolute and Relative Fallacies Example: "They debated whether his emotional appeal was fallacious. Absolute fallacies: non sequiturs, formal errors—he hadn't committed those. Relative fallacies: emotional appeals can be fallacious in some contexts, appropriate in others. Here, asking for compassion was relevant. The law said: relatively, not absolutely fallacious. She accepted the nuance, which is rare in online arguments."
