Let's see, heterological is a descriptionary word that describes other words that do not describe themselves which would lead one to believe it to be itself heterological, but if heterological is heterological then it describes itself and is therefore autological instead. So lets take it to be autological, well if heterological is autological it describes itself and is therefore heterological. . . In a formal way: Heterological is heterological if and only if it is not heterological. Paradoxes: Brain pain never felt so good.
