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."
