 Here we seem to have an indirect non-explicit conflict of obligations, if we assume that satisfying both obligations is practically impossible. Yet, unlike in our prior example, where the two promises might naturally have been on a par, we would all agree that the obligation to help my child overrides my obligation to meet you for lunch. In other words, the first obligation is defeated by the second obligation, which takes precedence. Ordinarily, we would also assume that no other obligation overrides my obligation to rush my child to the hospital, so that this obligation is an all things considered non-overridden obligation, but not so for the obligation to meet you for lunch. Furthermore, we are also prone to say that the situation is one where the general obligation we have to keep our appointments (or to keep our promises, still more generally) has an exception—the circumstances are extenuating.
