'The occasions on which any person (except one in a thousand) has it in his power to do this on an extended scale--in other words, to be a public benefactor--are but exceptional; and on these occasions alone is he called on to consider public utility; in every other case private utility, the interest or happiness of some few persons, is all he has to attend to.' And that these few persons should be those endeared to her by every domestic tie no argument was needed to prove. That their happiness would be in proportion to her own well-doing, and power to remove their risks of indigence, required no proving either to her now. By a sorry but unconscious misapplication of sound and wide reasoning did the active mind of Ethelberta thus find itself a solace. At about the midnight hour she felt more fortified on the expediency of marriage with Lord Mountclere than she had done at all since musing on it. In respect of the second query, whether or not, in that event, to conceal from Lord Mountclere the circumstances of her position till it should be too late for him to object to them, she found her conscience inconveniently in the way of her theory, and the oracle before her afforded no hint. 'Ah--it is a point for a casuist!' she said. An old treatise on Casuistry lay on the top shelf. She opened it--more from curiosity than from guidance this time, it must be observed--at a chapter bearing on her own problem, 'The disciplina arcani, or, the doctrine of reserve.' Here she read that there were plenty of apparent instances of this in Scripture, and that it was formed into a recognized system in the early Church. With reference to direct acts of deception, it was argued that since there were confessedly cases where killing is no murder, might there not be cases where lying is no sin? It could not be right--or, indeed, anything but most absurd--to say in effect that no doubt circumstances would occur where every sound man would tell a lie, and would be a brute or a fool if he did not, and to say at the same time that it is quite indefensible in principle. Duty was the key to conduct then, and if in such cases duties appeared to clash they would be found not to do so on examination. The lesser duty would yield to the greater, and therefore ceased to be a duty. This author she found to be not so tolerable; he distracted her. She put him aside and gave over reading, having decided on this second point, that she would, at any hazard, represent the truth to Lord Mountclere before listening to another word from him. 'Well, at last I have done,' she said, 'and am ready for my role.'
