Knowing how to keep a friend is more important than gaining a new one.
To find one real friend in a lifetime is a good fortune; to keep him is a blessing.
Friendship multiplies the good of life and divides the evil.
Don’t take the wrong side of an argument just because your opponent has taken the right side.
Don’t lie, but don’t tell the whole truth.
Do not show your wounded finger for everything will knock up against it.
Do pleasant things yourself, but unpleasant things through others.
There is no revenge like oblivion, for it is the entombment of the unworthy in the dust of their own nothingness.
Do not commit yourself to anybody or anything, for that is to be a slave, a slave to every man above all, keep yourself free of commitments and obligations— they are the device of another to get you into his power.
Even knowledge has to be in the fashion, and where it is not, it is wise to affect ignorance.
