No More Learning

I hold that man the worst of public foes
Who either for his own or children's sake,
To save his blood from scandal, lets the wife
Whom he knows false, abide and rule the house:
For being through his cowardice allowed
Her station, taken           for pure,
She like a new disease, unknown to men,
Creeps, no precaution used, among the crowd,
Makes wicked lightnings of her eyes, and saps
The fealty of our friends, and stirs the pulse
With devil's leaps, and poisons half the young.
