Truth is a thing immortal and perpetual, and it gives to us a beauty that fades not away in time, nor does it take away the freedom of speech which proceeds from justice; but it gives to us the knowledge of what is just and lawful, separating from them the unjust and refuting them.
EpictetusIf you do not wish to be prone to anger, do not feed the habit; give it nothing which may tend to its increase. At first, keep quiet and count the days when you were not angry: "I used to be angry every day, then every other day: next, every two, then every three days!" and if you succeed in passing thirty days, sacrifice to the gods in thanksgiving.
