Context

“but what shall we say now, Captain Harville? If the change be not from outward circumstances, it must be from within; it must be nature, man's nature, which has done the business for Captain Benwick." "No, no, it is not man's nature. I will not allow it to be more man's nature than woman's to be inconstant and forget those they do love, or have loved. I believe the reverse. I believe in a true analogy between our bodily frames and our mental; and that as our bodies are the strongest, so are our feelings; capable of bearing most rough usage, and riding out the heaviest weather."” source
