The illustrious archbishop of Cambray was of more worth than his chambermaid, and there are few of us that would hesitate to pronounce, if his palace were in flames, and the life of only one of them could be preserved, which of the two ought to be preferred … Supposing the chambermaid had been my wife, my mother or my benefactor. This would not alter the truth of the proposition. The life of Fénelon would still be more valuable than that of the chambermaid; and justice, pure, unadulterated justice, would still have preferred that which was most valuable. Justice would have taught me to save the life of Fénelon at the expense of the other. What magic is there in the pronoun "my", to overturn the decisions of everlasting truth?
