But it is not every unjust design, though indicated by some outward act, which can authorize and direct hostilities. For if the actual commission of crimes and aggressions is, in some cases, proper to be overlooked, much more will it be a mark of deliberate caution to use the same forbearance, where nothing further than the pure design of aggression appears. A forbearance which Cicero justifies upon the possibility that the enemy may have repented of his design, before the execution of it. No conclusive inference can be drawn from the severity of Mosaic Law against all intended acts of impiety and murder. For, in comparing human laws with the divine counsels, whose depths we cannot sound, we are liable to run into error; and the impulse of anger, where it is attended with no fatal consequence, is a case in which the infirmity of human nature calls for pardon. For altho' the precepts of the decalogue are designed to lay a restraint upon unlawful desires as well as upon unlawful actions, yet in addition to the spiritual sense, that which is called the carnal, or external commandment applies to those dispositions that are manifested by some open act. This interpretation may be deduced from a passage in the gospel of St. Mark, c. x. 19, where the prohibition to defraud is immediately preceded by the injunction not to steal. So that intended aggressions are not to be punished by force of arms, except in cases of atrocity, where the very design threatens consequences of the greatest danger. All punishment therefore must have in view either security against future aggressions, reparation for the injury done to national or private honour, or it must be used as an example of awful severity.
