Three causes in play in Persuasion relate to the Elliot fortune, renting Kellynch, and Lady Russell's charge to care for Lady Elliot's daughters. In the first, Sir Walter's wasted fortune forced a move to an economical lifestyle and lodgings that still allowed for the appearance of an elegant life while being secretly frugal.
In any other place Sir Walter might judge for himself; and would be looked up to, as regulating the modes of life in whatever way he might choose to model his household.
The end of these measures in response to the cause was that of saving comfort and appearances.
In regard to the second, the renting Kellynch facilitated an unexpected reunion between Wentworth and Anne while Wentworth was expecting the Elliot family to be permanently removed from the area.
A very few days more, and Captain Wentworth was known to be at Kellynch
The end of these consequences of the causative action was the forced a confrontation within each of their feelings toward the other.
In regard to the third, Lady Russell's made promise to Lady Elliott upon her deathbed to look after her daughters, especially Anne. Her promise to be the reinforcing conduit of the good and sensible lessons Lady Elliot taught that alone could contradict the ways of the silly and vain Sir Walter was the precipitating and driving factor in Lady Elliot's protest against Anne's engagement or marriage to Wentworth.
[On Lady Russell's] kindness and advice, Lady Elliot mainly relied for the best help and maintenance of the good principles and instruction which she had been anxiously giving her daughters.
The end of this promised obligation was that Lady Russell pressed her responsibility to protect Anne to too fine a point thus sabotaging Anne's chance for youthful happiness.
