We now leave the Westminster Reviewer to alter and amend his "magnificent principle" as he thinks best. Unlimited, it is false. Properly limited, it will be barren. The "greatest happiness principle" of the 1st of July, as far as we could discern its meaning through a cloud of rodomontade, was an idle truism. The "greatest happiness principle" of the 1st of October is, in the phrase of the American newspapers, "important if true." But unhappily it is not true. It is not our business to conjecture what new maxim is to make the bones of sages and patriots stir on the 1st of December. We can only say that, unless it be something infinitely more ingenious than its two predecessors, we shall leave it unmolested. The Westminster Reviewer may, if he pleases, indulge himself like Sultan Schahriar with espousing a rapid succession of virgin theories. But we must beg to be excused from playing the part of the vizier who regularly attended on the day after the wedding to strangle the new Sultana. The Westminster Reviewer charges us with urging it as an objection to the "greatest happiness principle" that "it is included in the Christian morality." This is a mere fiction of his own. We never attacked the morality of the Gospel. We blamed the Utilitarians for claiming the credit of a discovery, when they had merely stolen that morality, and spoiled it in the stealing. They have taken the precept of Christ and left the motive; and they demand the praise of a most wonderful and beneficial invention, when all that they have done has been to make a most useful maxim useless by separating it from its sanction. On religious principles it is true that every individual will best promote his own happiness by promoting the happiness of others. But if religious considerations be left out of the question it is not true. If we do not reason on the supposition of a future state, where is the motive? If we do reason on that supposition, where is the discovery?
