On my view, the notion of moral oughtness or duty is not explicable simply in terms of the concepts of goodness and badness. |
There is a sense of divine oughtness from which there is no escape. |
Oughtness, may I suggest, consists in the power which a greater good has over a lesser good in compelling our choices. |
Every attempt to derive oughtness from rightness must, as we have shown, either end in an illogical system or destroy the possiblity of a separate science of Ethics at all. |
