"The cause of anger is the belief that we are injured; this belief, therefore, should not be lightly entertained. We ought not to fly into a rage even when the injury appears to be open and distinct: for some false things bear the semblance of truth. We should always allow some time to elapse, for time discloses the truth."
Lucius Annaeus Seneca
(4 B.C.-A.D. 65) Roman Stoic philosopher, statesman, dramatist, "Seneca the Younger"
