11. A variety of specifying circumstances may place one and the same action in many various species of virtue or vice. Thus a religious robbing his parents would sin at once against justice, piety, and religion. A nun preferring death to dishonour practises three virtues, chastity, fortitude, and religion. 12. The means chosen may be of four several characters:-- (a) A thing _evil of itself_ and inexcusable under all conceivable circumstances; for instance, blasphemy, idolatry, lying. (b) _Needing excuse_, as the killing of a man, the looking at an indecent object. Such things are not to be done except under certain circumstances and with a grave reason. Thus indecent sights may be met in the discharge of professional duty. In that case indeed they cease to be indecent. They are then only indecent when they are viewed without cause. The absence of a good motive in a case like this commonly implies the presence of a bad one. (c) _Indifferent_, as walking or sitting down. (d) _Good of itself_, but liable to be vitiated by circumstances, as prayer and almsgiving; the good of such actions may be destroyed wholly or in part by their being done out of a vain motive, or unseasonably, or indiscreetly. 13. It is said, "If thy eye be single, thy whole body shall be lightsome." (St. Matt., vi., 22.) The eye is the intention contemplating the end in view. Whoever has placed a good end before him, and regards it steadily with a well-ordered love, never swerving in his affection from the way that reason would have him love, must needs take towards his end those means, and those only, which are in themselves reasonable and just: as it is written: "Thou shalt follow justly after that which is just." (Deut. xvi., 20.) Thus I am building a church to the glory of God; money runs short: I perceive that by signing a certain contract that must mean grievous oppression of the poor, I shall save considerable expense, whereas, if I refuse, the works will have to be abandoned for want of funds. If I have purely the glory of God before my eyes, I certainly shall not sign that contract: for injustice I know can bear no fruit of Divine glory. But if I am bent upon having the building up in any case, of course I shall sign: but then my love for the end in view is no longer pure and regulated by reason: it is not God but myself that I am seeking in the work. Thus an end entirely just, holy, and pure, purifies and sanctifies the means, not formally, by investing with a character of justice means in themselves unjust, for that is impossible,--the leopard cannot change his spots,--but by way of elimination, removing unjust means as ineligible to my purpose, and leaving me only those means to choose from which are in themselves just.
