To refute such an argument is superfluous; it is based on a groundless assertion. The moral sentiments of men have differed to infinity. With regard to a few classes of actions, the moral judgments of most, though not of all, men have been alike. With regard to others, they have differed, through every shade or degree, from slight diversity to direct opposition. But this is exactly what we should expect on the principle of utility. With regard to some actions, the dictates of utility are the same at all times and places, and are so obvious as hardly to admit of mistake or doubt. On the other hand, men's positions in different ages and nations are in many respects widely different; so that what was useful there and then is useless or pernicious here and now. Moreover, since human tastes are various, and human reason is fallible, men's moral sentiments often widely differ in the same positions. He next alludes to some prevailing misconceptions in regard to utility. One is the confusion of the _test_ with the _motive_. The general good is the test, or rather the index to the ultimate measure or test, the Divine commands; but it is not in all, or even in most cases, the motive or inducement. The principle of utility does not demand that we shall always or habitually attend to the general good; although it does demand that we shall not pursue our own particular good by means that are inconsistent with that paramount object. It permits the pursuit of our own pleasures as pleasure. Even as regards the good of others, it commonly requires us to be governed by partial, rather than by general benevolence; by the narrower circle of family and friends rather than by the larger humanity that embraces mankind. It requires us to act where we act _with the utmost effect_; that is, within the sphere best known to us. The limitations to this principle, the adjustment of the selfish to the social motives, of partial sympathy to general benevolence, belong to the detail of ethics.
