8 Do not, I pray you, regard these general remarks— applying as they do to all young women— as intended to insult you or to take you to task. I write in a spirit of apprehension, yet pray that you may never know the nature of my fears. A woman's reputation is a tender plant; it is like a fair flower which withers at the slightest blast and fades away at the first breath of wind. Especially is this so when she is of an age to fall into temptation and the authority of a husband is wanting to her.
For the very shadow of a husband is a wife's safeguard. What has a widow to do with a large household or with troops of retainers? As servants, it is true, she must not despise them, but as men she ought to blush before them. If a grand establishment requires such domestics, let her at least set over them an old man of spotless morals whose dignity may guard the honour of his mistress. I know of many widows who, although they live with closed doors, have not escaped the imputation of too great intimacy with their servants.
These latter become objects of suspicion when they dress above their degree, or when they are stout and sleek, or when they are of an age inclined to passion, or when knowledge of the favour in which they are secretly held betrays itself in a too confident demeanour. For such pride, however carefully concealed, is sure to break out in a contempt for fellow-servants as servants. I make these seemingly superfluous remarks that you may keep your heart with all diligence and guard against every scandal that may be broached concerning you.
