MULTI-VALUED LOGIC

Even more serious trouble arises around concepts like inversion of states or values. In binary logic the opposite of '1' is '0'. Or the opposite of 'true' is 'false'. It is reasonable to assume that if '0' is 'false' and '1' is true that '2' as a third state has to mean something like 'perhaps'. But 'perhaps' as we understand it is no state. And we also do not have an inversion for it.
