Meditations 11.15

How unsound and insincere is he who says, I have determined to deal with thee in a fair way!—What are thou doing, man? There is no occasion to give this notice. It will soon show itself by acts. The voice ought to be plainly written on the forehead. Such as a man's character is, he immediately shows it in his eyes, just as he who is beloved forthwith reads everything in the eyes of lovers. The man who is honest and good ought to be exactly like a man who smells strong, so that the bystander as soon as he comes near him must smell whether he choose or not. But the affectation of simplicity is like a crooked stick. Nothing is more disgraceful than a wolfish friendship [false friendship]. Avoid this most of all. The good and simple and benevolent show all these things in the eyes, and there is no mistaking.

Marcus Aurelius, Meditations 11.15, translated by George Long

How rotten at the core is he, how counterfeit, who proclaims aloud: I have elected to deal straightforwardly with thee! Man, what art thou at? There is no need to give this out. The fact will instantly declare itself. It ought to be written on the forehead. There is a ring in the voice that betrays it at once, it flashes out at once from the eyes, just as the loved one can read at a glance every secret in his lover's looks. The simple and good man should in fact be like a man who has a strong smell about him, so that, as soon as ever he comes near, his neighbour is, will-he nill-he, aware of it. A calculated simplicity is a stiletto. There is nothing more hateful than the friendship of the wolf for the lamb. Eschew that above all things. The good man, the kindly, the genuine, betrays these characteristics in his eyes and there is no hiding it.

Marcus Aurelius, Meditations 11.15, translated by C. R. Haines
