Quote

Silence is safer than speech.

Keep silence for the most part, and speak only when you must, and then briefly.

Let there be a door to thy mouth, that it may be shut when need arises, and let it be carefully barred, that none may rouse thy voice to anger, and thou pay back abuse with abuse.

Teach thy tongue to say 'I do not know', and thou shalt progress.

Your silence will not protect you.

While you are proclaiming peace with your lips, be careful to have it even more fully in your heart.

Let the veil of silence fall presently over what happened afterwards. Silence, too, can speak out.

Silence is better than unmeaning words.

Whereof one cannot speak, thereof one must be silent.
