"All the things and the kinds that come about
surely have a point from which they start out.
Honor or disgrace that comes unto you
surely reflects your degree of virtue.
In rotten meat bugs are generated.
In fish that's spoiled maggots are created.
Lazy, haughty men who forget their place
shall have misfortune and ruin to face.
Rigid things get themselves used for bracing.
Pliant things get themselves used for lacing.
If with corruption your person is filled,
It's this upon which hate toward you will build."

The Xunzi from: An exhortation on learning
