The Master said,
"There are some with whom we may study in common,
But we shall find them unable to go along with us to principles.
Perhaps we may go on with them to principles,
But we shall find them unable to get established in those along with us.
Or if we may get so established along with them,
We shall find them unable to weigh occurring events along with us."
The Analects of Confucius
Book 9, Chapter 29
