Austen Said:

with all the cost and care of an anxious and expensive education, he had brought up his daughters without their understanding their first duties, or his being acquainted with their character and temper.

had there been no young woman in question, had there been no young person of either sex belonging to him, to be endangered by the society or hurt by the character of Mrs. Rushworth, he would never have offered so great an insult to the neighbourhood as to expect it to notice her. As a daughter, he hoped a penitent one, she should be protected by him, and secured in every comfort, and supported by every encouragement to do right, which their relative situations admitted; but farther than that he could not go. Maria had destroyed her own character, and he would not, by a vain attempt to restore what never could be restored, by affording his sanction to vice, or in seeking to lessen its disgrace, be anywise accessory to introducing such misery in another man's family as he had known himself.
