Context

“she parades it more and more, and shows no sign of wishing to give up even the smallest part of it. It is this which makes us despair of being able to do anything with her and feel that either she or we must go. Gratitude and Revenge Gratitude is as much an evil to be minimised as revenge is. Justice, our law and our law courts are for the taming and regulating of revenge. Current prices and markets and commercial regulations are for the taming of gratitude and its reduction from a public nuisance to something which shall at least be tolerable.” source
