 First, unlike anything else, there is no conceivable circumstance in which we regard our own moral goodness as worth forfeiting simply in order to obtain some desirable object. By contrast, the value of all other desirable qualities, such as courage or cleverness, can be diminished, forgone, or sacrificed under certain circumstances: Courage may be laid aside if it requires injustice, and it is better not to be witty if it requires cruelty. There is no implicit restriction or qualification to the effect that a commitment to give moral considerations decisive weight is worth honoring, but only under such and such circumstances.
