"Only conceive how comfortable they will be!

Five hundred a year! I am sure I cannot imagine how they will spend half of it; and as to your giving them more, it is quite absurd to think of it. They will be much more able to give you something."

"Upon my word," said Mr Dashwood, "I believe you are perfectly right.
My father certainly could mean nothing more by his request to me than what you say."

The above passage reminded me of something in another book:

Dugald Stewart’s Elements of the Philosophy of the Human Mind (1792), contains the following:

What we commonly call sensibility, depends, in a great measure, on the power of imagination. Point out two men, any object of compassion; --a man, for example, reduced by misfortune from easy circumstances to indigence. The one feels merely in proportion to what he perceives by his senses. The other follows, in imagination, the unfortunate man to his dwelling, and partakes with him and his family in their domestic distresses.... As he proceeds in the painting, his sensibility increases, and he weeps, not for what he sees, but for what he imagines. It will be said, that it was his sensibility which originally aroused his imagination; and the observation is undoubtedly true; but it is equally evident, on the other hand, that the warmth of his imagination increases and prolongs his sensibility. “
