Ophelimity from greek "Ophelimos" "useful" is an economic concept introduced by Vilfredo Pareto as a measure of purely economic satisfaction, so he could use the already well-established term utility as a measure of a more broadly based satisfaction encompassing other dimensions as well, such as the ethical, moral, religious, and political.[1] As such, it corresponds to the sense in which utility is often used in economic calculations. Irving Fisher proposed replacing ophelimity (and thus utility as it is commonly construed) with the term wantability.[2]
