Seneca · On the vitality of the soul and its attributes
Letters 113.32
Fasten deep in your mind that which I remarked a short space above: that it makes no difference how many persons are acquainted with your uprightness. Those who wish their virtue to be advertised are not striving for virtue but for renown. Are you not willing to be just without being renowned? Nay, indeed you must often be just and be at the same time disgraced. And then, if you are wise, let ill repute, well won, be a delight. Farewell.
Seneca, Letters to Lucilius 113.32, translated by Richard Mott Gummere
