Special pleading is a term used to describe an argument that is based on exemption or exception rather than evidence or reason. This term also refers to the tactic in which one seeks to justify a position by resorting to an exception to the rule. Synonyms for special pleading include begging the question, loading the dice, and stacking the deck. Other terms that may be used to describe special pleading include arguing from ignorance, arguing from emotion, and moving the goalposts. While special pleading can be effective in gaining a temporary advantage in an argument, it is generally considered a fallacious tactic and is not a valid way to justify a position.
