MARCUS AURELIUS. MEDITATIONS. Book vii. 11.AT ANY things there be, which oftentimes insensibly trouble and vex thee, as not armed against them with patience, because they go not ordinarily under the name of pains, which indeed are of the same nature as pain; as to slumber unquietly, to suffer heat, to want appetite: when therefore any of these things make thee discontented, check thyself with these words: "Now hath pain given thee the foil: thy courage hath failed thee."
