Vei alltid dine tanker før du sier noe, for hos mange løper tungen fra tankene.
Til Demonicus, vers 41.
Always when you are about to say anything, first weigh it in your mind; for with many the tongue outruns the thought.
Always when you are about to say anything, first weigh it in your mind; for with many the tongue outruns the thought. Let there be but two occasions for speech — when the subject is one which you thoroughly know and when it one on which you are compelled to speak. On these occasions alone is speech better than silence; on all others, it is better to be silent than to speak.
