Men seek retreats for themselves, in country houses, on shores, and in the hills; and you, too, are especially wont to long for such things. But this is completely the mark of the most unphilosophical soldier, since it is open to you at any hour you wish to retire into yourself.
"Nowhere can man find a quieter or more untroubled retreat than in his own soul. Constantly then grant yourself this retirement, and so renew yourself."
Let your concise premises be brief and fundamental, which as soon as you have recurred to them will be sufficient to clear away all gloom and send you back without irritation to the duties you must confront. For what is it that troubles you? The wickedness of men?
Reflect on the judgment that rational beings are born for one another, that patience is part of justice, and that men transgress unwittingly. Consider how many who lived in enmity, suspicion, hatred, and combat have been stretched out dead and turned to dust. Be quiet at last.
