Every man knows the smell of his own fart.
Recompense injury with justice, and recompense kindness with kindness.
To know everything is to know nothing, but to know nothing is to know everything.
For one word a man is often deemed to be wise, and for one word he is often deemed to be foolish. We should be careful indeed what we say.
If a man sets his heart on benevolence he will be free from evil.
The person of benevolence never worries.
