7. What a man does from fear, he is said to do under compulsion, especially if the fear be applied to him by some other person in order to gain a purpose. Such compulsory action is distinguished in ordinary parlance from voluntary action. And it is certainly less voluntary, inasmuch as the will is hedged in to make its choice between two evils, and chooses one or other only as being the less evil of the two, not for any liking to the thing in itself. Still, all things considered, the thing is chosen, and the action is so far voluntary. We may call it voluntary in the concrete, and involuntary in the abstract. The thing is willed as matters stand, but in itself and apart from existing need it is not liked at all. But as acts must be judged as they stand, by what the man wills now, not by what he would will, an act done under fear is on the whole voluntary. At the same time, fear sometimes excuses from the observance of a law, or of a contract, which from the way in which it was made was never meant to bind in so hard a case. Not all contracts, however, are of this accommodating nature; and still less, all laws. But even where the law binds, the penalty of the law is sometimes not incurred, when the law was broken through fear.

SECTION II.—Of the determinants of morality in any given action.
1. The morality of any given action is determined by three elements, the end in view, the means taken, and the circumstances that accompany the taking of the said means. Whoever knows this principle, does not thereby know the right and wrong of every action, but he knows how to go about the enquiry. It is a rule of diagnosis.
2. In order to know whether what a man does befits him as a man to do, the first thing to examine is that which he mainly desires and wills in his action. Now the end is more willed and desired than the means. He who steals to commit adultery, says Aristotle, is more of an adulterer than a thief. The end in view is what lies nearest to a man's heart as he acts. On that his mind is chiefly bent; on that his main purpose is fixed. Though the end is last in the order of execution, it is first and foremost in the order of intention. Therefore the end in view enters into morality more deeply than any other element of the action. It is not, however, the most obvious determinant, because it is the last point to be gained; and because, while the means are taken openly, the end is often a secret locked up in the heart of the doer, the same means leading to many ends, as the road to a city leads to many homes and resting-places. Conversely, one end may be prosecuted by many means, as there are many roads converging upon one goal.
3. If morality were determined by the end in view, and by that alone, the doctrine would hold that the end justifies the means. That doctrine is false, because the moral character of a human act depends on the thing willed, or object of volition, according as it is or is not a fit object. Now the object of volition is not only the end in view, but likewise the means chosen. Besides the end, the means are likewise willed. Indeed, the means are willed more immediately even than the end, as they have to be taken first.
4. A good action, like any other good thing, must possess a certain requisite fulness of being, proper to itself. As it is not enough for the physical excellence of a man to have the bare essentials, a body with a soul animating it, but there is needed a certain grace of form, colour, agility, and many accidental qualities besides; so for a good act it is not enough that proper means be taken to a proper end, but they must be taken by a proper person, at a proper place and time, in a proper manner, and with manifold other circumstances of propriety.
5. The end in view may be either single, as when you forgive an injury solely for the love of Christ: or multiple co-ordinate, as when you forgive both for the love of Christ and for the mediation of a friend, and are disposed to forgive on either ground separately; or multiple subordinate, as when you would not have forgiven on the latter ground alone, but forgive the more easily for its addition, having been ready, however, to forgive on the former alone; or cumulative, as when you forgive on a number of grounds collectively, on no one of which would you have forgiven apart from the rest.
6. Where there is no outward action, but only an internal act, and the object of that act is some good that is willed for its own sake, there can be no question of means taken, as the end in view is immediately attained.
7. The means taken and the circumstances of those means enter into the morality of the act, formally as they are seen by the intellect, materially as they are in themselves. (See what is said of ignorance, c. iii., s. i., nn. 3-5, p. 27.) This explains the difference between formal and material sin. A material sin would be formal also, did the agent know what he was doing. No sin is culpable that is not formal. But, as has been said, there may be a culpable perversion of the intellect, so that the man is the author of his own obliquity or defect of vision. When Saul persecuted the Christians, he probably sinned materially, not formally. When Caiphas spoke the truth without knowing it, he said well materially, but ill formally.
