20 Mar exception
A deviation from a rule. Exception may be a misnomer. Whenever you find an exception, you are likely to find the action of a different rule that brought about the exception. To accept the idea of an exception, we must first agree that all rules are absolutely true or false. In multi-valued logic, we attempt to find the rules that are being followed and ignore those that are not. Multi-valued logic presupposes that there may be no such thing as an exception.
