"The purchase, according to the Federal view of the Constitution, was perfectly legitimate. … But the Federalists in general took narrow and partisan views, and in order to embarrass the administration resorted to quibbles which were altogether unworthy the party which had boasted of Washington as its chief and Hamilton as the exponent of its doctrines. … The Federal leaders did not stop at cavils; they insisted that the unconstitutional extension of territory was in effect a dissolution of the Union, so that they were at liberty to contemplate and plan for a final disruption."

"Monroe like Washington was re-chosen President by a vote practically unanimous. One, however, of the 232 electoral votes cast was wanting to consummate this exceptional honor; for a New Hampshire elector, with a boldness of discretion which, in our days and especially upon a close canvass, would have condemned him to infamy, threw away upon John Quincy Adams the vote which belonged like those of his colleagues to Monroe, determined, so it is said, that no later mortal should stand in Washington’s shoes. Of America’s Presidents elected by virtual acclamation history furnishes but these two examples; and as between the men honored by so unapproachable a tribute of confidence, Monroe entered upon his second term of office with less of real political opposition than
Washington." J. SCHOULER.

"The ‘Liberator’ was a weekly journal, bearing the names of William Lloyd Garrison and Isaac Knapp as publishers. Its motto was, ‘Our Country is the world, Our Countrymen are Mankind,’ a direct challenge to those whose motto was the Jingo cry of those days, ‘Our Country, right or wrong!’ … The salutatory of the ‘Liberator’ avowed that its editor meant to speak out without restraint. ‘I will be as harsh as truth and as uncompromising as justice. On this subject [Slavery] I do
not wish to think, or speak, or write with moderation. No! No! Tell a man whose house is on fire to give a moderate alarm; tell him to moderately rescue his wife from the hands of the ravisher; tell the mother to gradually extricate her babe from the fire into which it as fallen but urge me not to use moderation in a cause like the present. I am in earnest I will not equivocate I will not excuse I will not retreat a single inch I will be heard.’ This promise was amply kept."

"When Seward came to the territorial question, his words created a sensation. ‘We hold,’ he said, ‘no arbitrary authority over anything, whether acquired lawfully or seized by usurpation. The Constitution regulates our stewardship; the Constitution devotes the domain (i. e. the territories not formed into States) to union, to justice, to defense, to welfare, and to liberty. But there is a higher law than the Constitution, which regulates our authority over the domain, and devotes it to the same noble purposes. The territory is a part, no inconsiderable part, of the common heritage of mankind, bestowed upon them by the Creator of the Universe. We are His stewards, and must so discharge our trust as to secure in the highest attainable degree their happiness.’ This remark about ‘a higher law’ … was destined to have a transcendent moral influence. A speech which can be condensed into an aphorism is sure to shape convictions."
