even more extensively disgusting. Speculations pointed to monstrous offences, bore upon their very face and frontispiece the intimation that they related to cases rare and anomalous. But sometimes casuistry pressed into the most hallowed recesses of common domestic life. The delicacy of youthful wives, for example, was often not less grievously shocked than the manliness of husbands, by refinements of monkish subtlety applied to cases never meant for religious cognisance--but far better left to the decision of good feeling, of nature, and of pure household morality. Even this revolting use of casuistry, however, did less to injure its name and pretensions than a persuasion, pretty generally diffused, that the main purpose and drift of this science was a sort of hair-splitting process, by which doubts might be applied to the plainest duties of life, or questions raised on the extent of their obligations, for the single benefit of those who sought to evade them. A casuist was viewed, in short, as a kind of lawyer or special pleader in morals, such as those who, in London, are known as Old Bailey practitioners, called in to manage desperate cases--to suggest all available advantages--to raise doubts or distinctions where simple morality saw no room for either--and generally to teach the art, in nautical phrase, of sailing as near the wind as possible, without fear of absolutely foundering. Meantime it is certain that casuistry, when soberly applied, is not only a beneficial as well as a very interesting study; but that, by whatever title, it is absolutely indispensable to the _practical_ treatment of morals. We may reject the name; the thing we cannot reject. And accordingly the custom has been, in all English treatises on ethics, to introduce a good deal of casuistry under the idea of special illustration, but without any reference to casuistry as a formal branch of research. Indeed, as society grows complex, the uses of casuistry become more urgent. Even Cicero could not pursue his theme through such barren generalizations as entirely to evade all notice of special cases: and Paley has given the chief interest to his very loose investigations of morality, by scattering a selection of such cases over the whole field of his discussion.
