Implicature
Implicature
When someone says “If P, then Q,” we often understand them tosuggest or imply or implicate that “If not P, then not Q.”
But that is not a consequence of what they have said, or part ofthe meaning of what they said. (They’ve uttered a conditional, nota biconditional!)
Philosophers of language have a name for this sort of thing:implicature.

Implicature
Content or Implicature? Testing by Cancellation
Here’s a test for telling whether something is a consequence ofwhat was said or just something that you are “reading between thelines”:
Can you “cancel” the sentence without contradicting yourself?
Suppose I say: “If the virus doesn’t mutate, we’ll be okay.”
And then I say: “In fact, even if it does mutate, we’ll still probablybe okay.”
I haven’t contradicted what I said earlier. I have justcanceled an implicature: something that you might(reasonably) have “read between the lines.”

Implicature
Be careful of implicature
Implicature can mess with your head. For instance, you might read
If a is in back of b, then it is larger than b.
Then when you find out that a isn’t in back of b, you mightassume that a isn’t larger than b.
But that would be a mistake!
The conditional will still be true when the antecedent is false andthe consequent is true!
