When these are modified under changed circumstances, moral duty also undergoes a change and it does not always remain the same. For a given promise or agreement may turn out in such a way that its performance will prove detrimental either to the one to whom the promise has been made or to the one who has made it. If, for example, Neptune, in the drama, had not carried out his promise to Theseus, Theseus would not have lost his son Hippolytus; for, as the story runs, of the three wishes/a that Neptune had promised to grant him the third was this: in a fit of anger he prayed for the death of Hippolytus, and the granting of this prayer plunged him into unspeakable grief. Promises are, therefore, not to be kept, if the keeping of them is to prove harmful to those to whom you have made them; and, if the fulfilment of a promise should do more harm to you
