Smart and stupid

It's no surprise that the fool has talked the wise one down;
Once content that the scholar had nothing to counter him,
he began to shout vulgarity even more loudly;
until he was finally exhausted—but when he had rested,
the wise man said, so that he would not be indebted to him in reply:
"Do you know why the bell is loud? Because it is empty within."
Ignacy Krasicki (1735-1801)
