Letters 79.18

Virtue has never failed to reward a man, both during his life and after his death, provided he has followed her loyally, provided he has not decked himself out or painted himself up, but has been always the same, whether he appeared before men’s eyes after being announced, or suddenly and without preparation. Pretence accomplishes nothing. Few are deceived by a mask that is easily drawn over the face. Truth is the same in every part. Things which deceive us have no real substance. Lies are thin stuff; they are transparent, if you examine them with care. Farewell.

Seneca, Letters to Lucilius 79.18, translated by Richard Mott Gummere
