The Bible: "Encouragement for the Christian "Truther" ", The NET Bible, Proverbs 18:13 (1000 - 350 BC)

If you've ever tried to tell someone about one of the countless official lies that we're bombarded with on a regular basis, and they've "answered" you before even bothering to listen to what you have to say...

... well, the writer of this proverb said it all thousands of years ago:

 "The one who gives an answer before he listens that is his folly and his shame.^"

And the NET Bible adds this helpful note (with my emphases):

"Poor listening and premature answering indicate that the person has a low regard for what the other is saying, or that he is too absorbed in his own ideas.

The Mishnah lists this as the second characteristic of the uncultured person (m. Avot 5:7)."
