No deceit is so veiled as that which lies concealed behind the semblance of courtesy.
Be a pattern to others and then all will go well.
Never injure a friend, even in jest.
Scurrility has no object in view but incivility; if it is uttered from feelings of petulance, it is mere abuse; if it is spoken in a joking manner, it may be considered raillery.
It is besides necessary that whoever is brave should be a man of great soul.
To live long, live slowly.
