We answered, with much more lenity than we should have shown to such nonsense, had it not proceeded, as we supposed, from Mr Bentham, that interest was synonymous with greatest happiness; and that, therefore, if the word OUGHT has no meaning, unless used with reference to interest, then, to say that mankind ought to pursue their greatest happiness, is simply to say, that the greatest happiness is the greatest happiness; that every individual pursues his own happiness; that either what he thinks his happiness must coincide with the greatest happiness of society or not; that, if what he thinks his happiness coincides with the greatest happiness of society, he will attempt to promote the greatest happiness of society whether he ever heard of the "greatest happiness principle" or not; and that, by the admission of the Westminster Reviewer, if his happiness is inconsistent with the greatest happiness of society, there is no reason why he should promote the greatest happiness of society. Now, that there are individuals who think that for their happiness which is not for the greatest happiness of society is evident. The Westminster Reviewer allowed that some of these individuals were in the right; and did not pretend to give any reason which could induce any one of them to think himself in the wrong. So that the "magnificent principle" turned out to be, either a truism or a contradiction in terms; either this maxim--"Do what you do;" or this maxim, "Do what you cannot do." The Westminster Reviewer had the wit to see that he could not defend this palpable nonsense; but, instead of manfully owning that he had misunderstood the whole nature of the "greatest happiness principle" in the summer, and had obtained new light during the autumn, he attempts to withdraw the former principle unobserved, and to substitute another, directly opposed to it, in its place; clamouring all the time against our unfairness, like one who, while changing the cards, diverts the attention of the table from his sleight of hand by vociferating charges of foul play against other people. The "greatest happiness principle" for the present quarter is then this,--that every individual will best promote his own happiness in this world, religious considerations being left out of the question, by promoting the greatest happiness of the whole species. And this principle, we are told, holds good with respect to kings and aristocracies as well as with other people.
