'We know,' says he, 'no universal proposition respecting human nature which is true but one--that men always act from self-interest.'" "It is manifest from the sequel, that the writer is not the dupe of the confusion; but many of his readers may be so. If, indeed, the word "self-interest" could with propriety be used for the gratification of every prevalent desire, he has clearly shown that this change in the signification of terms would be of no advantage to the doctrine which he controverts. It would make as many sorts of self-interest as there are appetites, and it is irreconcilably at variance with the system of association proposed by Mr Mill." "The admirable writer whose language has occasioned this illustration, who at an early age has mastered every species of composition, will doubtless hold fast to simplicity, which survives all the fashions of deviation from it, and which a man of genius so fertile has few temptations to for sake." When Macaulay selected for publication certain articles of the Edinburgh Review, he resolved not to publish any of the three essays in question; for which he assigned the following reason:-- "The author has been strongly urged to insert three papers on the Utilitarian Philosophy, which, when they first appeared, attracted some notice, but which are not in the American editions. He has however determined to omit these papers, not because he is disposed to retract a single doctrine which they contain, but because he is unwilling to offer what might be regarded as an affront to the memory of one from whose opinions he still widely dissents, but to whose talents and virtues he admits that he formerly did not do justice. Serious as are the faults of the Essay on Government, a critic, while noticing those faults, should have abstained from using contemptuous language respecting the historian of British India. It ought to be known that Mr Mill had the generosity, not only to forgive, but to forget the unbecoming acrimony with which he had been assailed, and was, when his valuable life closed, on terms of cordial friendship with his assailant." Under these circumstances, considerable doubt has been felt as to the propriety of republishing the three Essays in the present collection. But it has been determined, not without much hesitation, that they should appear. It is felt that no disrespect is shown to the memory of Mr Mill, when the publication is accompanied by so full an apology for the tone adopted towards him; and Mr Mill himself would have been the last to wish for the suppression of opinions on the ground that they were in express antagonism to his own. The grave has now closed upon the assailant as well as the assailed. On the other hand, it cannot but be desirable that opinions which the author retained to the last, on important questions in politics and morals, should be before the public.
