Volen-told to to reduce pricing?
I only said no.
What I should have said was ask your mother.
Exception paradox: if every rule has an exception, then there must be an exception to the rule that every rule has an exception.
From the logical point of view, this can be taken as a proof that the sentence "every rule has an exception" is false - a simple example of a proof technique known as reductio ad absurdum. More formally,
- Every rule has an exception. (Statement)
- "Every rule has an exception" has an exception. (By 1)
- There exists some rule R without exception. (By 2)
- Since R is a rule, by the first statement it must have an exception. But by 3, it does not have an exception - a contradiction.
Or, in another view:
- Every rule has an exception. (Statement)
- "Every rule has an exception" has an exception. (By 1)
- There exists some rule R without exception. (By 2)
- Since R is a rule, by the first statement it must have an exception. Therefore, the statement should be the only rule that doesnīt have an exception, what could be called a contradiction.
- The rule itself represents its own exception, because it should be the only rule without an exception.
In this last point of view there isnīt a contradiction but a systematic interpretation. This is a reason why it could not be considered a real paradox. Otherwise, the sentence could be read: "Every other rule, except this one, has an exception." This is a hermeneutic rule, saving the meaning, and represents a common technique applied on legal and constitutional norms, by extracting from the different interpretations of the statement the possible one, even if implicit.
