When common aphorisms don't make sense

I’ve never understood the phrase, “the exception that proves the rule.”
An exception proves there isn’t a “rule” to begin with, right?

I’ve never understood the phrase, “the exception that proves the rule.”
An exception proves there isn’t a “rule” to begin with, right?
Theme based on Derek Punsalan's Grid Focus.

I have never, ever understood that saying. And I was always too embarrassed to admit it, because it sounds really clever.
I just don’t understand it at all.
Well, I think it means at least this: If there were no rule, there could be no exception; that we recognize something as an exception, proves there is a rule–a standard–from which the exception deviates.
Like if I let my daughter go to the mall with her friends THIS time, I want her to know it’s an exception, not a precedent. The rule is: There are better things to do than hang out at the mall.
Noel is exactly right. There can be no such thing as an exception if there are no rules. It’s much like G.K. Chesterton’s famous observation that “If there were no God, there would be no atheists.”
What’s funny is that “the exception that proves the rule” is a rule too.
Often it just means that the original rule was inadequately expressed.
We say, “the rule is X,” when really the rule is: if X then Y, otherwise Z. All that together is really the rule, at least in computer programming.
I think “prove” should be understood as “demonstrates” – a rule has been established, and the exception serves to show the presence of that rule.
For instance, if you pass a store that has a sign out front saying “10% off on Saturdays”, it’s reasonable to assume that they charge full price on other days. The sign that advertises the exception demonstrates the usual rule: everything is not on sale Sunday-Friday.
I guess calling something a “rule” is just a universal way to convey, “this how it is 99 times out of 100″.
It’s a stretch of the term “rule”; although, perhaps a different word could/should be used?
I wonder how many exceptions can there be for a rule to still be a rule? Such as, if there are more than 5 or even 10 exceptions, shouldn’t it be considered a “common occurrence” instead of an actual rule?
The classic rule and exception:
I before “e”, except after “c”.
And yet there are exceptions to this exception:
weird
sufficient
Argh!!!
David White has it right.
The meaning of the statement, “The exception proves the rule” is that stating an exception to a rule implies that no other exceptions exist, i.e., that the rule applies under all other conditions.
For well-documented support of this interpretation, see the last entry on this page:

How deconstructive of you, Wes! I feel the system collapsing already.
In his book The Mother Tongue, Bill Bryson cites this as an example of a “fossil”–a word preserved in an expression long after its meaning has shifted–saying “prove” once meant “test.” Other examples of fossils are “neck of the woods” (neck was once a parcel of land) and “bank teller” (tell once meant count). Interesting stuff.
And that is the exception that proves the rule!
But if you want to get theological, it’s a great way of expressing what makes a miracle miraculous.
Helpful comments, all. Thanks! I feel like I’ve learned a thing or two (or three).
“The exception that proves the rule:” Maybe it’s more clear to say, “The exception that demonstrates/indicates the existence of/calls for a/fits snugly – opposites attract – into a / rule?” Or, “The sin that proves [existence of] The Law?” (” ‘Without the Law, there is no transgression.’ “
We have this saying in Russian, and I could never understand it either.
I have never thought that saying was very accurate. The “exception” is simply that an “exception”. It doesn’t prove anything except that an exception was made.
Hey people, words have meaning. Use them correctly.
Ok, try this: The general rule is that ministers of the gospel should get formal training or else their sermons are going to be exegetical bunk.
Charles Spurgeon is the exception that proves the rule, because though, yes, he did not get formal training, he read so much on his own that he effectively did.
