Just one more untrue thing you hear at the hall that hits you in the face when you leave.
Others:
1. Wordly people are evil; most are not. Most are decent people.
2. Those who go to college are seeking fame or fortune or are vain.
3. Evolutionists are godless; most are not. Evolutionists are in constant disagreement; they're not.
4. College is a waste of time.
The biggest lie, though, is the one in your talk:
There is no happiness outside the truth.
THAT is a whopper.
