Stupidity

Does anyone understand what Pope John Paul II was talking about when he said, "Stupidity is also a gift of God, but one mustn't misuse it."  Does anyone know the context within which this was said and the source of the quotation?  All I can find is the quoted sentence, repeated over and over again.

If you have any idea about this, please leave a comment.  In a few days I will post what I believe he might have meant.
