The allegation that the subjugation of Mexico would be the means of enlightening the Mexicans, of improving their social state, and of increasing their happiness, is but the shallow attempt to disguise unbounded cupidity and ambition. Truth never was or can be propagated by fire, and sword, or by any other than purely moral means. By these, and by these alone, the Christian religion was propagated, and enabled, in less than three hundred years, to conquer idolatry. During the whole of that period, Christianity was tainted by no other blood than that of its martyrs. The duties of the people of the United States towards other nations are obvious. Never losing sight of the divine precept, "Do to others as you would be done by," they have only to consult their own conscience. For our benevolent Creator has implanted in the hearts of men the moral sense of right and wrong, and that sympathy for other men, the evidences of which are of daily occurrence. It seems unnecessary to add anything respecting that false glory which, from habit and the general tenor of our early education, we are taught to admire. The task has already been repeatedly performed, in a far more able and impressive manner, than anything I could say on the subject. It is sufficient to say that, at this time, neither the dignity or honor of the nation demand a further sacrifice of invaluable lives, or even of money. The very reverse is the case. The true honor and dignity of the nation are inseparable from justice. Pride and vanity alone demand the sacrifice. Though so dearly purchased, the astonishing successes of the American arms have at least put it in the power of the United States to grant any terms of peace, without incurring the imputation of being actuated by any but the most elevated motives. It would seem that the most proud and vain must be satiated with glory, and that the most reckless and bellicose should be sufficiently glutted with human gore. A more truly glorious termination of the war, a more splendid spectacle, an example more highly useful to mankind at large, cannot well be conceived, than that of the victorious forces of the United States voluntarily abandoning all their conquests, without requiring anything else than that which was strictly due to our citizens.
