"You shall hear," he said. "From all this it appears that a military man may demand satisfaction on the spot from the person who has injured him--not, indeed, with the intention of rendering evil for evil, but with that of preserving his honor--_non ut malum pro malo reddat, sed ut conservat honorem_. See you how carefully, because the Scripture condemns it, they guard against the intention of rendering evil for evil? This is what they will tolerate on no account. Thus Lessius observes (_De Just._, liv. ii., c. 9, d. 12, n. 79), that, 'If a man has received a blow on the face, he must on no account have an intention to avenge himself; but he may lawfully have an intention to avert infamy, and may, with that view, repel the insult immediately, even at the point of the sword--_etiam cum gladio_.' So far are we from permitting any one to cherish the design of taking vengeance on his enemies, that our fathers will not allow any even to _wish their death_--by a movement of hatred. 'If your enemy is disposed to injure you,' says Escobar, 'you have no right to wish his death, by a movement of hatred; though you may, with a view to save yourself from harm.' So legitimate, indeed, is this wish, with such an intention, that our great Hurtado de Mendoza says that 'we may _pray God_ to visit with speedy death those who are bent on persecuting us, if there is no other way of escaping from it.'" (In his book, _De Spe_, vol. ii., d. 15, sec. 4, 48.) "May it please your reverence," said I, "the Church has forgotten to insert a petition to that effect among her prayers." "They have not put every thing into the prayers that one may lawfully ask of God," answered the monk. "Besides, in the present case, the thing was impossible, for this same opinion is of more recent standing than the Breviary. You are not a good chronologist, friend. But, not to wander from the point, let me request your attention to the following passage, cited by Diana from Gaspar Hurtado (_De Sub. Pecc._, diff. 9; Diana, p. 5; tr. 14, r. 99), one of Escobar's four-and-twenty fathers: 'An incumbent may, without any mortal sin, desire the decease of a life-renter on his benefice, and a son that of his father, and rejoice when it happens; provided always it is for the sake of the profit that is to accrue from the event, and not from personal aversion.'" "Good," cried I. "That is certainly a very happy hit, and I can easily see that the doctrine admits of a wide application. But yet there are certain cases, the solution of which, though of great importance for gentlemen, might present still greater difficulties." "Propose such, if you please, that we may see," said the monk. "Show me, with all your directing of the intention," returned I, "that it is allowable to fight a duel."
